Abstract

Background: Exhaled nitric oxide (FeNO) is a validated marker of eosinophilic inflammation. Fenom ProTM is a novel FDA-cleared monitor for FeNO. The American Thoracic Guidelines from 2005 recommend at least 6 s exhalation for adults and in some cases up to 10 s, and 4 s for children, and that the average of the first two valid exhalations is taken as the FeNO value. Methods: Clinical precision, 6 versus 10 s exhalations, the first versus the average of the first two valid exhalation methods comparison were evaluated for Fenom ProTM, as well as a methods comparison to the NIOX VERO® monitor. Results: The intent-to-treat population (n = 126) consisted of 83 adults, and 43 pediatric subjects with 16 subjects under 12 years of age. Clinical precision for 10 s exhalations on Fenom ProTM was excellent with a within-subject standard deviation (SD) range of 0.57–3.73 ppb and mean coefficient of variation (CV) range of 4.21% to 9.65%. The clinical precision for the separate adult and pediatric groups as well as for the 6 s exhalations were similar. The 10 and 6 s exhalation comparisons and one versus the average of two valid exhalations showed a high level of agreement. The Fenom ProTM and the NIOX VERO® monitors also demonstrated a high level of agreement with the values from the latter slightly lower (mean bias of −3.2 ppb). Conclusion: Fenom ProTM demonstrated eminently acceptable performance supporting its clinical utility. The data suggests that 6 s exhalations can be used in adults and children, and that one exhalation is adequate rather than obtaining the average of two exhalations on Fenom ProTM.

Abstract
In this study, four land use type soils from Yingtan Jiangxi Province China, i.e., forest (F), bamboo (B), tea plantation (TP) and upland (U), were collected, and gene of ammonia-oxidizing archaea (AOA) and bacteria (AOB), nirS, nirK, and nosZ were determined, to identify the effects of land use on abundance of microorganism in red soil and their role to nitrification and denitrification. The result shows that AOA copy numbers ranged from 6.20 × 106 to 6.58 × 106 copies/g soil and AOB varied from 4.18 × 106 to 7.41 × 106 copies/g soil. The highest AOA and AOB were all measured in U soil that was the highest pH and the lowest C/N ratio. The Abundance of AOB is stimulated by enhancing soil pH due to lime application and more available NH4+ from N fertilization that could be responsible for the high net nitrification rate in U soil. Meanwhile, nirK copy numbers ranged from 6.46 × 106 to 7.05 × 106 copies/g soil, nirS from 5.50 × 106 to 5.85 × 106 copies/g soil, and nosZ from 6.57 × 106 to 7.35 × 106 copies/g soil. The nirS (p<0.05) and nirK (p<0.05) was positively correlated with soil potential denitrification rate.

Abstract
It is well-known that there are some problems faced in cultivating peat-land as an agricultural land. The main problems are related to both its low soil acidity and its high cation exchange capacity. Previous studies showed that coastal sediment has shown its potential to overcome these constraints. This experiment is design to invent new potential coastal sediment resource after the closeness of Pantai Kijing areas as the coastal sediment source, and to study some of important basic chemical properties of coastal sediment collected from new sites. The samples were collected from 10 selected sites in District of Sambas, and analyzed in the Laboratory of Soil Chemistry and Soil Fertility of Faculty of Agriculture, Tanjungpura University. For other two districts we used secondary data from previous studies. It was found that (1) District of Sambas could be the most next potential coastal sediment source after the closeness the area of Pantai Kijing, (2) High pH and BS values of coastal sediment from District of Sambas are two important properties needed to improve poor soil properties in West Kalimantan, and (3) high base element content could be further resource in improving properties of upland degrade soil in West Kalimantan. It is highly recommended to do more further basic experiments in order to optimize this new coastal sediment funtion as soil ameliorant.

Abstract
Development of agricultural commodities, including for horticulture crops, must lead to suboptimal lands and often already degraded. The study aims to study the effectiveness of organic ameliorant in improving soil quality on degraded acidic upland and its impact on the productivity of chili plants. The study was conducted on acidic upland in Tamanbogo, East Lampung, using a randomized block design with six treatments and three replications. The treatment used 3 ameliorants namely compost, biochar KK-50, Biochar KK-20 with a dose of 20 t ha−1, each combined with and without mulch, the control treatment was without mulch and ameliorant. The results showed that the amelioration treatment had a significant effect on improving soil physical properties, indicated by the average BD values which was significantly lower and the soil porosity was significantly higher. The treatment of biochar also results in significantly higher aeration pores than control treatment. The average soil pH in the control treatment <5, while the average pH in the biochar treatment >5. The average potential soil K content at the biochar treatment was significantly higher. Amelioration treatment has a significant effect on the growth of chili plants. The average chili production in the amelioration treatment was relatively higher than control.

Abstract
A part of peatlands in Indonesia developed above sulfidic material. They spread around the tidal swamps area. Vertical tide movement will certainly bring a consequences to the behaviour of both materials, such as ash content and electrical conductivity properties. The research was conducted to study ash content and electrical conductivity of peatland with several thickness and acid sulphate soil under some hydrological conditions. The results showed that ash content and electrical conductivity decreased with increasing of peat thickness, especially in upper layer of peatland. Decrease and disappear of peat layer has increased the ash content and electrical conductivity in the peat layer and in the sulfidic layer. Declining of ground water level increased electrical conductivity of soil.

Published: December 2019

Abstract
Efforts to restore the environmental conditions of ex-coal mine land through reclamation can be monitored through land quality indicators. Soil quality is a soil condition that describes the soil as healthy, which has good physical, chemical and biological properties of soil, and high productivity in a sustainable manner. The quality of soil in biology is largely determined by the number of micro-bodies in the soil (especially fungi, actinomycetes, and bacteria). This aim of this study is to describe changes in soil quality from the abundance of several types of soil microorganisms after the application of ameliorant and re-vegetation on coal mine land in Muaro Jambi Regency, Jambi Province. This activity was carried out in the coal mine reclamation land that had been reclaimed / stockpiled at PT Gea Lestari, Tanjung Pauh Village, Mestong District, Muaro Jambi Regency from January to December 2016. The study design used was Randomized Block Design with treatment factors: 10 tons of manure/ha and manure 10 tons/ha + mycorrhizae 30 g/plant. Each treatment was repeated 3 times. The plants used are corn, soybeans, Setaria and ground cover plants (leguminoceae) among conservation plants. Samples obtained from 3 replications were composite for biology analysis of the soil. The results of the biological analysis of the soil obtained various results both at the initial conditions of the soil at the study site and after the results of the assessment. The initial conditions of the land indicate that the reclamation land of former coal mines has a diversity of soil microorganisms, namely cellulotic fungi, cellulotic bacteria, mycorrhizae, propragules fungi and heterotrophic aerobic bacteria and has C-mic activity. Re-vegetation on reclaimed land of ex-coal mines shows indicators of macro-fauna and microorganism life that increase in number and activity.

Published: December 2019

Abstract
Soil erosion is one of the most important natural resource management problems in watershed zone that affects soil quality, reduce soil nutrient content and further may harms food resilience. Erosion produced sediment is the biggest pollutant of surface water, contributes further to eutrophication and affecting water quality. Radionuclide Fallout (RNF) have been developed by Unesco to measure erosion qualitatively using isotope trace found in soils surface originated nuclear bomb test. This method has been applied in the Region of Sembalun at Lombok island and Kertasari at Greater Bandung in 2017. Grasslands of Mt Rinjani and Mt. Papandayan have been chosen as the reference sites. Kertasari area possess steeper slopes and receive more rainfall than Sembalun Area. The soil profiles at the expected reference on Mt. Papandayan contain less 137Cs radioactivity than those of Mt. Rinjani. Both study area represents locations where the activity of 137Cs was undetected due to the topsoil removal by high rate of erosion process. Undetected 137Cs radiation is more widespread in Kertasari than in Sembalun area. 137Cs RNF methods for quantitative assessments of erosion seems possess the limitation for the utilization in the steeply sloping region with high soil erodibility due to the presence of undetected radiation area. The method will still useful to be applied in a more flat area for both erosion and sedimentation study.

Published: December 2019

Abstract
The main function of applying biochar on acid mineral soil is to overcome soil acidity for optimizing the soil utilization. The high ability of biochar to retain nutrients can increase the efficiency of inorganic fertilizers. In the field, it can be reached by enriching biochar with inorganic fertilizers. The objective of study was to improve soil properties and inorganic fertilizer efficiency in degraded acid mineral soil in East Lampung. The study was conducted in 2018 at Taman Bogo Research station, Purbolinggo sub district, East Lampung district. The study used a randomized block design with 4 replications. Treatments tested were: 1) Cocoa shell Biochar (BC CS) + 100% Ponska dose (mixed), 2) BC CS + 50% Ponska dose (mixed), 3) BC CS + 100% ponska dose (digged), 4) BC corn cobs (CC) + 100% Ponska dose (mixed), 5) BC CC + 50% Ponska dose (mixed), 6) BC CC + 100% ponska dose (digged), 7) No BC+100% ponska dose (control). The parameters observed were the soil properties and crop yield. The results showed that BC CS was more effective in reducing soil acidity and yielded higher N, K and P significantly than BC CC. The biochar application can increase the K content up to 209-471%. Application a 50% Ponska dose only affected the soil K content. BC CC was better in improving soil physical properties than BC CC. The Ponska enrichment was more effective for BC CC application compared to BC CS although the highest yield was obtained in the BC CS application. The reduction of 50% Ponska dose decreased maize yield by 8.1% and 17%, but needed to be evaluated economically to choose profitable treatment.

Published: December 2019

Abstract
Women in developing nations are more exposed to climatic risk due to higher dependence on the natural resources that tend to be more sensitive to these changes. Quality climate change information for rural women farmers can be a decisive factor in how they perceive and cope with these changes, thus the purpose of this study. Purposive sampling technique was used to select 5 communities each from the five Local Government Areas in Kwara North, giving a total of 25 communities. Raosoft online sample size calculator was used to determine the sample size. Three hundred and eighty-four (384) copies of the questionnaire were administered; in addition, Focus Group Discussion and oral interviews were conducted to determine the; (i) sources of climate information (ii) medium/language of communication and, (iii) adequacy of climate information. Results from the data analyzed indicates that about (68.0%) of all the women farmers in the study area do not always receive adequate climate information as their sources of information are not official, while only (32.0%) of the respondents received information in English. Also, the contents of climate information generated and disseminated in Nigeria and particularly the study area does not meet the actual needs of the farming population. Recommendations are therefore made accordingly for improvement.
