Precision Farming - The Management Implications
Creators: name: King, Tony
Publisher: name: Unknown
Year: 1997
Subjects: Research and Development/Tech Change/Emerging Technologies

description: Precision Farming with ifs use of satellite technologies in arable farming is now with us and will have a dramatic effect on large scale farm management in the next decade and beyond. It is a fast moving and dynamic development, with much of the agricultural supply industry becoming involved. Like Integrated Crop Management, Precision Farming will become an increasingly pervasive management concept. This paper reviews some of the wide range of uses, possibilities and hoped for benefits of Precision Farming, and sets out to identify those aspects that are likely to make a major contribution to the management of growing arable crops and their profitability. The successful adoption of these technologies will require manufacturers and suppliers of equipment, services and software to agree common (world-wide?) standards. As Precision Farming is developing many of the management systems of crop production are being called into question, with much research now necessary to underpin our understanding of the essentials of crop production. This paper identifies the principal areas of research and development in the UK.

Evening Squeaker
Material: Two males, NGK-Nimba 0019, NGK-Nimba 0130 (Fig. 6A).
Comments: On a rainy day they were found together with a juvenile Nimba Toad (N. occidentlais) below a stone in montane grassland (07°35.555’N, 008°25.788’W; 1,235 m asl). These males had an oval to slender elongated body and measured 15.5 and 21.0 mm SUL, respectively. Arthroleptis crusculum always possesses a granular to warty dorsal skin. Its habitat differs from other species of the genus which are present on Mounts Nimba. Arthrolpetis nimbaensis, A. langeri, and A. krokosua, and occur in rainforest and/or farmbush (Guibé and Lamotte 1958b; Rödel et al. 2009; Adum et al. 2011; Nopper et al. 2012; Sandberger-Loua et al. 2018a). Arthrolpetis crusculum occurs in high elevation grasslands up to 1,750 m asl during the rainy season and seems to survive the dry season in gallery forests and at the edges of marshes (Guibé and Lamotte 1958b).

description: We obtain a novel bound state spectrum of the low energy excitations near the Fermi points of graphene in the presence of a charge impurity. The effects of possible short range interactions induced by the impurity are modelled by suitable boundary conditions. The spectrum in the subcritical region of the effective Coulomb coupling is labelled by a parameter which characterizes the boundary conditions and determines the inequivalent quantizations of the system. In the supercritical region we obtain a renormalization group flow for the effective Coulomb coupling.

Mottled Squeaker
Material: Two males, NGK-Nimba 0021 (Fig. 6B), NGK-Nimba 0022.
Comments: These squeaker frogs were widespread in the forest area as well as in farmlands within the vegetation, where several concealed males emitted their insect-like chirping calls which cannot be assigned to any morphotaxa. They occured from 425 to 847 m asl. A male of 23.0 mm in SUL was captured in a patch of forest and retained as voucher (07°35.233’N, 008°25.190’W; 847 m asl). Another male voucher (SUL 24.0 mm) was recorded in an agricultural area (07°31.928’N, 008°25.401’W; 425 m asl). Arthroleptis poecilonotus -complex are larger than A. langeri but smaller than A. krokosua. The two vouchers may comprise different species, of which one could be conspecific with A. nimbaensis. However, currently that cannot be clarified (see Rödel and Bangoura 2004; Channing and Rödel 2019). All of these Arthroleptis species, apart from A. crusculum, may have similar habitat requirements (Rödel et al. 2009; Adum et al. 2011; Nopper et al. 2012; Sandberger-Loua et al. 2018a).

description: Rapid sky localization of gravitational wave sources is crucial to enable prompt electromagnetic follow-ups. In this article, we present a novel semianalytical approach for sky localization of gravitational waves from compact binary coalescences. We use the Bayesian framework with an analytical approximation to the prior distributions for a given astrophysical model. We derive a semianalytical solution to the posterior distribution of source directions. This method only requires one-fold numerical integral that marginalizes over the merger time, compared to the five-fold numerical integration otherwise needed in the Bayesian localization method. The performance of the method is demonstrated using a set of binary neutron stars (BNS) injections on Gaussian noise using LIGO-Virgo's design and O2 sensitivity. We find the median of 90% confidence area in O2 sensitivity to be $\mathcal{O}(10^2) ~\mathrm{deg}^2$, comparable to that of the existing LIGO-Virgo online localization method Bayestar and parameter estimation toolkit LALInference. In the end, we apply this method to localize the BNS event GW170817 and find the 50% (90%) confidence region of 11 $\mathrm{deg}^2$ (50 $\mathrm{deg}^2$). The detected optical counterpart of GW170817 resides within our 50% confidence area.

Western Night Frog
Material: Two males, NGK-Nimba 0014, NGK-Nimba 0023, and one female, NGK-Nimba 0024 (Fig. 6C).
Comments: While A. occidentalis was previously mostly recorded in patches of lowland forests (Rödel and Branch 2002; Rödel and Bangoura 2002; Ernst and Rödel 2006; Hillers and Rödel 2007; Hillers et al. 2008b; Rödel and Glos 2019), on Mounts Nimba the species occurs in altitudinal forest habitats as well (Guibé and Lamotte 1958a). During the night several active individuals were detected among leaf litter in a patch of forest (07°35.233’N, 008°25.190’W; 847 m asl), close to fast-flowing streams. Male SULs ranged from 45.0‒ 50.2 mm (N = 3), while females measured from 46.0‒61.0 mm (N = 9). The majority of specimens had a dark brown dorsum, although one female exhibited an orange color. In contrast to the general forest habitat requirements of this species we found some, presumably migrating, frogs at night, in the core rainy season near a crystal-clear stream in predominantly grassy savannah (07°35.453’N, 008°24.957’W; 843 m asl). During the day, they were hidden underneath stones.

Winter habitat selection and use of clearcuts by elk in the White River drainage of southeastern British Columbia
Creators: name: Churchill, Brian Phillip
Publisher: name: University of British Columbia
Year: 2010

description: This study of elk winter habitat selection was conducted from June 1975 to May 1977. Surveys were conducted from November to April to observe elk use of habitat, patterns of use within clearcuts, and elk reaction to human activities and vehicle traffic. Programmes of habitat mapping, vegetation description and pellet group counts were conducted during the rest of the study period. The two winters of the study were mild. Snow depths never exceeded 45 cm, the depth hypothesized to initiate elk movement to areas of lower snowdepth. During these mild snow conditions elk selected clearcuts for feeding but utilized forested habitats for resting and escape cover. Subsequent studies in the same area (McLellan 1978) showed contrasting avoidance of clearcuts for two months during deep snow conditions where snowdepths exceeded 50 cm. Within clearcuts elk were observed to select moderate slopes further than 200 m from active roads for feeding and resting. Feeding activities within clearcuts showed selection for ridges, grass/forb vegetation and burned areas. Elk showed varying responses to slash accumulations during feeding activity. Elk selected the largest clearcut site and no preference for areas near edge of clearcuts was shown. Elk showed a strong avoidance reaction to human activity and vehicle traffic, fleeing to forest cover when disturbed. Recommendations for forest management are included.
Weather Related Risk and Crop Choice in Alberta, Canada

Subjects: Resource /Energy Economics and Policy

description: The growth of crops in Alberta is highly sensitive to weather factors. In order to capture profitable returns on average, Alberta farmers have adopted early maturing cereal varieties and oilseeds. Nevertheless considerable risk is involved in crop choice and management practices. The purpose of this paper is to analyze the crop choice decision made by farmers in southern Alberta and the effect of weather-induced risk as well as risk arising from price variability. A crop growth simulation model (Erosion Productivity Impact Calculator) was used to simulate the growth of all major crops grown in sourthern Alberta, under six different seed/harvest combinations, and covering 30 years of weather data. Given EPIC’s strength for simulating drought years, it was coupled with a farm-level Target MOTAD model which assesses bottom-side risk. Some observations from the analysis on the brown soil zone in southern Alberta were: farmers in general appear to exhibit risk aversion; risk aversion to yield variability appears to be significant in the brown soil zone; price variability appears to be relatively less important than yield variability; and forage crops are a tool for reducing income variability induced by price variability.

Based on the ergodicity considerations we conclude that the isothermal susceptibility will diverge as $T\to 0$ both in finite clusters and in the bulk system in two non-ergodic regions of the phase diagram of the system.

Material: Three males, NGK-Nimba 0025, NGK-Nimba 0026 (Fig. 6D), NGK-Nimba 0027.
Comments: Cardioglossa occidentalis is a nocturnal leaf litter frog, distributed along forest streams from Sierra Leone to Ghana (Rödel et al. 2001; Rödel and Branch 2002; Ernst and Rödel 2006; Blackburn et al. 2008; Hillers et al. 2008c). During the night, males frequently emitted insect-like calls (see Rödel et al. 2001), and were well concealed below leaf litter along forest streams. Three males were collected near a small stream running through a slightly degraded forest patch that was dominated by bamboo (07°32.993’N, 008°24.753’W; 425 m asl). Their SULs ranged from 27.0‒29.0 mm.

NADA: A new code for studying self-gravitating tori around black holes

Year: 2008

description: We present a new two-dimensional numerical code called Nada designed to solve the full Einstein equations coupled to the general relativistic hydrodynamics equations. The code is mainly intended for studies of self-gravitating accretion disks (or tori) around black holes, although it is also suitable for regular spacetimes. Concerning technical aspects the Einstein equations are formulated and solved in the code using a formulation of the standard 3+1 (ADM) system, the so-called BSSN approach. A key feature of the code is that derivative terms in the spacetime evolution equations are computed using a fourth-order centered finite difference approximation in conjunction with the Cartoon method to impose the axisymmetry condition under Cartesian coordinates (the choice in Nada), and the puncture/moving puncture approach to carry out black hole evolutions. Correspondingly, the general relativistic hydrodynamics equations are written in flux-conservative form and solved with high-resolution, shock-capturing schemes. We perform and discuss a number of tests to assess the accuracy and expected convergence of the code, namely (single) black hole evolutions, shock tubes, and evolutions of both spherical and rotating relativistic stars in equilibrium, the gravitational collapse of a spherical relativistic star leading to the formation of a black hole. In addition, paving the way for specific applications of the code, we also present results from fully general relativistic numerical simulations of a system formed by a black hole surrounded by a self-gravitating torus in equilibrium.

description: "He was an artist of thought and mind, with his thinking he performed a drama", says Rüdiger Safranski, the renown Nietzsche-biographer, in an interview. In an unique way the 19th century philosopher Friedrich Nietzsche - born 1844 in Lützen, expired 1900 in Weimar - forethought the 20th century unlike (most probably) any other European intellectual of his time. As a radical proponent of the Enlightenment, he was one of the most striking masterminds of a secular worldview in 19th century Europe. For him Europe was a super-continental principle, he was pro Europe, but contra any form Eurocentrism. The following central streams of Nietzsche's thought shall be brought to discussion in this article: The era of modernity that has begun with the French Revolution postulating liberty, equality and fraternity, elevated ratio and reason to the central objectives of European modern secular society.

description: It is proven that the $\star$-product of field operators implies that the space of test functions in the Wightman approach to noncommutative quantum field theory is one of the Gel'fand-Shilov spaces $S^β$ with $β< 1/2$. This class of test functions smears the noncommutative Wightman functions, which are in this case generalized distributions, sometimes called hyperfunctions. The existence and determination of the class of the test function spaces in NC QFT is important for any rigorous treatment in the Wightman approach.

description: Given a random variable $N$ with values in ${\mathbb{N}}$, and $N$ i.i.d. positive random variables $\{μ_k\}$, we consider a queue with renewal arrivals and $N$ exponential servers, where server $k$ serves at rate $μ_k$, under two work conserving routing schemes. In the first, the service rates $\{μ_k\}$ need not be known to the router, and each customer to arrive at a time when some servers are idle is routed to the server that has been idle for the longest time (or otherwise it is queued). In the second, the service rates are known to the router, and a customer that arrives to find idle servers is routed to the one whose service rate is greatest. In the many-server heavy traffic regime of Halfin and Whitt, the process that represents the number of customers in the system is shown to converge to a one-dimensional diffusion with a random drift coefficient, where the law of the drift depends on the routing scheme. A related result is also provided for nonrandom environments.

description: We study the orbital evolution of the 4 giant planets of our solar system in a gas disk. Our investigation extends the previous works by Masset and Snellgrove (2001) and Morbidelli and Crida (2007, MC07), which focussed on the dynamics of the Jupiter-Saturn system. The only systems that we found to reach a steady state are those in which the planets are locked in a quadruple mean motion resonance (i.e. each planet is in resonance with its neighbor). In total we found 6 such configurations. For the gas disk parameters found in MC07, these configurations are characterized by a negligible migration rate. After the disappearance of the gas, and in absence of planetesimals, only two of these six configurations (the least compact ones) are stable for a time of hundreds of millions of years or more. The others become unstable on a timescale of a few My. Our preliminary simulations show that, when a planetesimal disk is added beyond the orbit of the outermost planet, the planets can evolve from the most stable of these configurations to their current orbits in a fashion qualitatively similar to that described in Tsiganis et al. (2005).

description: Quantization has been proven to be a vital method for improving the inference efficiency of deep neural networks (DNNs). However, it is still challenging to strike a good balance between accuracy and efficiency while quantizing DNN weights or activation values from high-precision formats to their quantized counterparts. We propose a new method called elastic significant bit quantization (ESB) that controls the number of significant bits of quantized values to obtain better inference accuracy with fewer resources. We design a unified mathematical formula to constrain the quantized values of the ESB with a flexible number of significant bits. We also introduce a distribution difference aligner (DDA) to quantitatively align the distributions between the full-precision weight or activation values and quantized values. Consequently, ESB is suitable for various bell-shaped distributions of weights and activation of DNNs, thus maintaining a high inference accuracy. Benefitting from fewer significant bits of quantized values, ESB can reduce the multiplication complexity. We implement ESB as an accelerator and quantitatively evaluate its efficiency on FPGAs. Extensive experimental results illustrate that ESB quantization consistently outperforms state-of-the-art methods and achieves average accuracy improvements of 4.78%, 1.92%, and 3.56% over AlexNet, ResNet18, and MobileNetV2, respectively. Furthermore, ESB as an accelerator can achieve 10.95 GOPS peak performance of 1k LUTs without DSPs on the Xilinx ZCU102 FPGA platform. Compared with CPU, GPU, and state-of-the-art accelerators on FPGAs, the ESB accelerator can improve the energy efficiency by up to 65x, 11x, and 26x, respectively.

Large-eared Tree Frog
Material: Three males, NGK-Nimba 0017, NGK-Nimba 0018, NGK-Nimba 0131 (Fig. 6E).
Comments: Leptopelis macrotis is one of the largest species in the genus. It occurs in primary forests, preferentially at the edges of streams, from eastern Sierra Leone to Ghana (Schiøtz 1967; Rödel et al. 2014; Channing and Rödel 2019). In Ivory Coast, as in its entire range, the species is threatened due to forest degradation and conversion, e.g., two of its Ivorian sites (see Rödel and Branch 2002) have been recently converted into rubber plantations (P.J. Adeba, pers. comm.). During this survey, only three males of L. macrotis were recorded, two of which were found during the dry season. Both frogs (45.5 and 48.5 mm SUL) were perched on a branch of a broad leaf, at ~ 2.5 m height, close to a large stream (07°33.121’N, 008°25.036’W; 422 m asl). The third male (42.5 mm SUL), in contrast, was found in a degraded forest during the rainy season. This male was perched on a branch, at 75 cm above the ground, close to a large stream (07°31.932’N, 008°25.508’W; 387 m asl).

description: We investigate the pion and kaon (pi^+, K^+, K^0) electromagnetic form factors in the space-like region: Q^2 ~< 1 GeV, based on the gauged low-energy effective chiral action from the instanton vacuum in the large N_c limit. Explicit flavor SU(3) symmetry breaking is taken into account. The nonlocal contributions turn out to be crucial to reproduce the experimental data. While the pion electromagnetic form factor is in good agreement with the data, the kaon one seems underestimated. We also calculate the electromagnetic charge radii for the pion and kaon: _{pi^+}=0.455 fm^2, _{K^+}=0.486 fm^2 and _{K^0}=-0.055 fm^2 without any adjustable free parameter except for the average instanton size and inter-instanton distance, and they are compatible with the experimental data. The low-energy constant L_9 in the large N_c limit is estimated to be 8.42*10^{-3} from the pion charge radius.

description: Consider a mixed quantum mechanical state, describing a statistical ensemble in terms of an arbitrary density operator $ρ$ of low purity, $\trρ^2\ll 1$, and yielding the ensemble averaged expectation value $\tr(ρA)$ for any observable $A$. Assuming that the given statistical ensemble $ρ$ is generated by randomly sampling pure states $|ψ>$ according to the corresponding so-called Gaussian adjusted projected measure $[$Goldstein et al., J. Stat. Phys. 125, 1197 (2006)$]$, the expectation value $$ is shown to be extremely close to the ensemble average $\tr(ρA)$ for the overwhelming majority of pure states $|ψ>$ and any experimentally realistic observable $A$. In particular, such a `typicality' property holds whenever the Hilbert space $\hr$ of the system contains a high dimensional subspace $\hr_+\subset\hr$ with the property that all $|ψ>\in\hr_+$ are realized with equal probability and all other $|ψ> \in\hr$ are excluded.

Economic Analysis of Dairy Farms in Korea - Analysis of Milk Production Function, Analysis by Different Size of Cows
Creators: name: Kim, Jong Moo
Publisher: name: Unknown
Year: 1997
Subjects: Productivity Analysis

description: Milk is produced on dairy farms and consumed by the urban population. Dairy farmers must earn a higher level offarm income by applying economic level of input materials such as concentrates, farmers9 own labor and hired labor. There are different sizes of dairy farms having less than 10 cows, 10-15 cows and more than 15 cows. The increasing level of concentrates may increase the level of farm income per dairy cow as some results of analysis of production function. There are certainly different increasing/decreasing aspects of farmers9 own labor and hired labor affecting level of income per cow. It might be certainly necessary to have a further research on development of different size of dairy farms in relation to level of education and number of years by farm managers. The level of price of milk may also influence to increase and/or decrease size of dairy farms.

Hemispherical power asymmetry: parameter estimation from CMB WMAP5 data
Creators: name: Lew, Bartosz
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We reexamine the evidence of the hemispherical power asymmetry, detected in the CMB WMAP data using a new method. At first, we analyze the hemispherical variance ratios and compare these with simulated distributions. Secondly, working within a previously-proposed CMB bipolar modulation model, we constrain model parameters: the amplitude and the orientation of the modulation field as a function of various multipole bins. Finally, we select three ranges of multipoles leading to the most anomalous signals, and we process corresponding 100 Gaussian, random field (GRF) simulations, treated as observational data, to further test the statistical significance and robustness of the hemispherical power asymmetry. For our analysis we use the Internally-Linearly-Coadded (ILC) full sky map, and KQ75 cut-sky V channel, foregrounds reduced map of the WMAP five year data (V5). We constrain the modulation parameters using a generic maximum a posteriori method. In particular, we find differences in hemispherical power distribution, which when described in terms of a model with bipolar modulation field, exclude the field amplitude value of the isotropic model A=0 at confidence level of ~99.5% (~99.4%) in the multipole range l=[7,19] (l=[7,79]) in the V5 data, and at the confidence level ~99.9% in the multipole range l=[7,39] in the ILC5 data, with the best fit (modal PDF) values in these particular multipole ranges of A=0.21 (A=0.21) and A=0.15 respectively. However, we also point out that similar or larger significances (in terms of rejecting the isotropic model), and large best-fit modulation amplitudes are obtained in GRF simulations as well, which reduces the overall significance of the CMB power asymmetry down to only about 94% (95%) in the V5 data, in the range l=[7,19] (l=[7,79]).

Western Tree Frog
Material: Male, NGK-Nimba 0016 (Fig. 6F).
Comments: Leptopelis occidentalis is primary a rainforest treefrog, preferring forests near streams, and ranging from western Ghana, through Ivory Coast to Liberia (Schiøtz 1967; Rödel et al. 2005; Hillers and Rödel 2007; Hillers et al. 2009; Channing and Rödel 2019). After sunset (1830 h GMT), a male (41.5 mm SUL) with a uniform green dorsum was found perching on a shrub at the edge of a forest clearing along a stream (07°33.121’N, 008°25.036’W; 422 m asl). The species is known from several forests in Ivory Coast (Schiøtz 1967; Rödel and Branch 2002; Ernst and Rödel 2008).

Subjects: subject: Probability (math.PR)

description: Control-type particle filters have been receiving increasing attention over the last decade as a means of obtaining sample based approximations to the sequential Bayesian filtering problem in the nonlinear setting. Here we analyse one such type, namely the feedback particle filter and a recently proposed approximation of the associated gain function based on diffusion maps. The key purpose is to provide analytic insights on the form of the approximate gain, which are of interest in their own right. These are then used to establish a roadmap to obtaining well-posedness and convergence of the finite $N$ system to its mean field limit. A number of possible future research directions are also discussed.

Farm Management

description: In the European Union nutrient management is a topic of major political interest.The goal for nitrogen (N) is that groundwater should contain less than 50 mg nitrate/l. The general approach might result in a maximum amount of N or number of cattle allowed per ha. However, individual countries develop alternative routes and take additional measures to deal with nutrient losses. The odour of manure as part of the environment is not a main theme in the discussions. In The Netherlands emphasis is placed both on phosphorus (P) and on nitrogen. In addition to the European guideline for nitrate, ammonia volatilization (emission) should be reduced by 50-70% in the year of2000 compared with 1980. Regulations limit the amount of manure (expressed in P) applied per ha. For some years a manure (P) quotum is allocated to each farm. A more balanced P-supply to the land is achieved by transport of manure from surplus to deficit area's. Also lower P-contents of the concentrate feeds are stimulated. N-losses can mainly be reduced by adapting the farm operation. Several management practices were studied with the PR-dairy-farm-model to assess their contribution to the mineral losses. A combination of a more efficient use of fertilizer N, restricted grazing in combination with a more balanced ration, and to a less extent, a higher milk production/cow resulted in considerable reductions in nitrate leaching. Application of slurry by injection techniques diminishes the ammonia volatilization at farm-level by almost 50%. Other low emission techniques, such as low emission housing and covering of slurry storages, have relatively a high cost. In practice, slurry application by injection has become obligatory. Injection has as side effect, that the smell of manure is largely eliminated from the environment. Application of manure to the land is only allowed in the growing seasons. Form 1998 farmers with a higher stocking (2,5 dairycowunit) rate have to keep a nutrient balance sheet. On basis of the nutrient balance a tax will be imposed on surplusses of N and P.

description: A deep convolutional neural network (CNN) is developed to study symmetry energy $E_{\rm sym}(ρ)$ effects by learning the mapping between the symmetry energy and the two-dimensional (transverse momentum and rapidity) distributions of protons and neutrons in heavy-ion collisions. Supervised training is performed with labelled data-set from the ultrarelativistic quantum molecular dynamics (UrQMD) model simulation. It is found that, by using proton spectra on event-by-event basis as input, the accuracy for classifying the soft and stiff $E_{\rm sym}(ρ)$ is about 60% due to large event-by-event fluctuations, while by setting event-summed proton spectra as input, the classification accuracy increases to 98%. The accuracy for 5-label (5 different $E_{\rm sym}(ρ)$) classification task are about 58% and 72% by using proton and neutron spectra, respectively. For the regression task, the mean absolute error (MAE) which measures the average magnitude of the absolute differences between the predicted and actual $L$ (the slope parameter of $E_{\rm sym}(ρ)$) are about 20.4 and 14.8 MeV by using proton and neutron spectra, respectively. Fingerprints of the density-dependent nuclear symmetry energy on the transverse momentum and rapidity distributions of protons and neutrons can be identified by convolutional neural network algorithm.

The Economics of Milk Production in Alberta
Creators: name: Ross, Carlyle
Publisher: name: Unknown
Year: 1997
Subjects: Production Economics

description: New trade rules within Canada, and between Canada and the USA present many challenges and opportunities for Alberta’s dairy industry. This report is part of a larger study of the competitiveness of Alberta’s dairy industry. It examined the performance of dairy farms in Alberta and compared their performance with other dairy farms in Canada and the USA. Milk production in Canada occurs under strict production and price controls. Such controls make dairy farming in Alberta a stable and profitable business. In 1994, Alberta’s dairy farms earned 15 per cent return on equity and 18 per cent return on capital. Quebec dairy farms reported the highest cost of milk production, followed by Alberta. Alberta dairy farms had a feed and/or labour cost advantage relative to other provinces. Alberta also had a feed cost advantage over dairy farms in the USA. However, milk production costs in the US Pacific region were significantly lower than in Alberta. When more efficient Alberta dairy farms were considered, they had a significant cost advantage over their provincial counterparts, and a small advantage over dairy farms in the Pacific region. The report concluded that Alberta dairy farms were well positioned to take advantage of relaxed interprovincial as well as Canada/US agriculture trade rules.
