Abstract
Landfill sites collect tons of municipal solid waste (MSW) using an open dump mechanism, causing gases to emerge, which may cause disease and the greenhouse effect. Mainly, landfill environments are observed using a portable system that does not continuously monitor and measure emitted gas levels. It is also difficult to evaluate changes in landfill emissions over the long term unless they are monitored at regular intervals according to a detailed plan. This paper presents a new monitoring method to measure gas levels in landfill sites, which documents dynamic changes in gas composition concentrations over the long term. The system was placed in the middle area of the landfill and was charged using solar panels for convenience and greater efficiency during monitoring. While the instruments that are currently available are used for a specific parameter, this system can measure eight parameters, i.e., ambient concentration of methane (CH4), carbon dioxide (CO2), carbon monoxide (CO), temperature, humidity, wind direction, wind speed, and voltage level. The system was evaluated regarding its ability to monitor gas parameters continuously.

Published: November 2021

Abstract
Nickel ore mines have a high potential of landslides due to their weak material base, which consists of soil. It is caused by the increase of soil density in rain conditions, leading to decreased soil shear strength (c) and internal friction angle (ϕ). This research aims to determine the optimum value of the maximum iteration number based on the Cuckoo Search and Particle Swarm Optimization search method. In this research, the slope is analyzed using the 3 Dimensional limit equilibrium method “Simplified Bishop,” a slope stability analysis method that uses the principle of static equilibrium. Alongside this method, the Cuckoo Search and Particle Swarm Optimization is adopted. The Cuckoo Search and Particle Swarm Optimization are metaheuristic optimization techniques used as the slipped surface search method. Series of 3-dimensional limit equilibrium computation is performed using different amounts of nests in the cuckoo search method and different particle values and maximum iteration number. Cuckoo Search method to achieve optimal nest 100 and iteration of 80 with the fastest compute time of 3 minutes 49 seconds. While the Particle Swarm Optimization to achieve optimal on particles 60, iteration as much as 480 with a compute time of 6 minutes 46 second, with a factor of safety value of 1,12.

Abstract
It is necessary to observe and evaluate the performance of the authorized institutions, in particular, related to the sub-unit of the Environmental Agency, which manages the technical aspects (UPTD) and the five aspects of waste management to achieve better service to the people of Tembalang District. The UPTD is responsible for technical operations, including transporting domestic waste using arm roll and dump trucks, managing the cost budget plan, and supervising waste collection at waste collection site. Tembalang District has a minimum waste generation of 156 m3/day with a generation rate of 0.814 l/person/day and a maximum of 216 m3/day with a generation rate of 1.217 l/person/day. The implementation of the five management aspects in Tembalang District still needs to be evaluated from the operational, technical, and community participation aspects. This situation is related to the segregation and sorting of waste that has not been carried out, independent processing that has not gone well, and activities at the landfill that are not suitable. The community participation, public awareness, and concern for waste problems are still low where the independent waste management through waste treatment facility partnerships and waste banks are possible to do.

Published: November 2021

Abstract
The article presents the results obtained in the stationary experiment of the Novozybkovskaya SHOS. In the experiment, single-species crops of yellow alfalfa, boneless stalk and grass mixtures based on them were studied against the background of various doses of potash fertilizers (K120-180). The influence of potash fertilizers on the yield and quality of legumes and cereals, their mixed crops and a decrease in the content of 137Cs in hay is considered. It was found that the highest yield of hay of perennial grasses in both the first and second mowing was obtained in the P60K180 variant. The highest level of hay yield among the studied crops was noted in a grass mixture of yellow alfalfa with a boneless stalk. In terms of the yield of feed units and exchange energy per hectare, the alfalfa + stalk grass mixture exceeded single-species crops. Studies have established that the guaranteed receipt of normatively clean feeds based on yellow alfalfa, boneless stalk and grass mixtures based on them is provided by the use of phosphorus-potassium fertilizer in a dose P60K120.

Abstract
The ratios of pea and barley seeds for growing in mixed crops for the purpose of preparing juicy feed and obtaining grain fodder in the conditions of low-lying peatlands of the North-East of the Non-Chernozem zone of Russia are determined. Heat treatment of grain fodder from peas and barley in a ratio of 50:50 at a coolant temperature of 1100 C a duration of 30 minutes, as well as preservation of silage with LMAC (low molecular acid concentrate) reduced the solubility and cleavability of raw protein in the rumen, contributed to an increase in the use of nitrogen and energy for productive purposes when feeding lactating cows. Feeding of pea and barley silage processed with LMAC in the ratio (25:75) and processed grain mixture (50:50) as part of the main feeding diet of new – bodied cows increased the use of nitrogen taken – by 5.29%, digested-by 8.27 %. During the experiment period, the average daily milk yield of natural milk in the control group averaged 21.18 kg, in II-23.06 and in III – 25.49 kg. The difference in favor of the experimental group III was 4.31 kg (p < 0.05), and in II – 1.88 kg (p < 0.05) or 11.89 and 3.29%, respectively, in terms of 4% milk, the difference was 5.06 and 2.19 kg or 25.08 and 10.86 %. At the same time, the costs of exchange energy for obtaining 1 kg of milk with 4% fat content decreased by 10%, raw protein by more than 7 %.

Abstract
In the context of the progressive trend of aridization of the climate of the main agricultural regions in the forest-steppe and steppe zones, the problem of increasing and stabilizing the high productivity of forage crops is becoming more acute. Yellow alfalfa (Medicago falcata L.) is highly resistant to abiotic stresses such as drought and low temperatures. This crop is resistant to extremely stressful conditions for cultivation in arid conditions, high production potential for the production of various types of bulky forage. The limiting factor of the effective economic use of yellow alfalfa in the Central Black Earth region of Russia is the insufficient number of zoned varieties, only three. The zoned varieties of alfalfa that exist today do not fully meet the requirements of modern forage production, and the tasks of developing new varieties with increased productivity, competitive ability in grass mixtures and increased longevity are becoming urgent. A highly productive variety of yellow alfalfa Pavlovskaya 7 was previously created at the Voronezh Experimental Station for perennial grasses. The Pavlovskaya 7 variety is characterized by high resistance to fungal diseases and mycoplasmosis, drought resistance, and long (up to 12 years) productive longevity. Currently, the station is completing selection work to develop a new variety of yellow alfalfa with a complex of economically valuable traits and properties for conditions of insufficient moisture.

Abstract
Agriculture continues to move forward confidently. Before our eyes, the agrarian industry is reviving, becoming stronger, taking a strong position at the forefront of the Russian economy. The most important achievement of 2017 was a record grain harvest of 130 million tons. This result was achieved not only by increasing the cultivated areas, which increased by 620 thousand hectares in 2017, but also thanks to the record yield, which amounted to 28 kg / ha, which is 80% higher than in 2000. The maximum harvest in the history of new and Soviet Russia, which will ensure our country a strong leadership in the world wheat market. Russian agriculture remains a driver of the country’s economic development. For the second year in a row, we get a record harvest of not only grain, but also sugar beets and sunflowers, the production of soybeans, rapeseed and greenhouse vegetables is growing. In the new season, grain exports will reach 45 million tons, including more than 35 million tons of wheat. Russia is expanding the geography of its presence, having mastered new directions for the supply of agricultural products. At the end of 10 months of 2017, grain exports increased by 22% compared to the same period in 2016 and amounted to 32 million tons. During the same time, the export of Russian wheat exceeded 24 million tons, which is 23% more than a year earlier. … In Russia, over 17 years, the volume of grain production increased 2 times, sugar beet and sunflower - 2-3 times, soybeans and rapeseed - 10, greenhouse vegetables - 1.8, poultry meat - 6, pork - 2. Fish - 2 times. Greenhouse vegetable growing and horticulture are developing intensively. Progress is being made in the development of animal husbandry and aquaculture. The dairy industry is undergoing a significant transformation, and production volumes on farms are growing. These are new growth points for the agro-industrial complex. Thanks to the achievements of domestic scientists, grain production of agricultural crops can be increased due to many factors. One of the factors is foliar dressing with liquid micro- and macro-fertilizers. Therefore, we studied various combinations of liquid micro-, macrofertilizers, as well as the bio-logical product Albit, in order to identify the best option and recommend it for produc-tion.
The influence of the timing and methods of harvesting the seed grass of the eastern goat’s rue (Galega orientales Lam.) on the yield and sowing quality of seeds
Authors: Zolotarev V N 
Published: November 2021

Abstract
Eastern goat’s rue (Galega orientales Lam.) possesses high fodder productivity and accumulates a large amount of vegetative mass with high humidity for harvesting for seeds. This greatly complicates the harvesting of grass stand for seeds. One of the ways to solve this problem is to carry out desiccation of the grass stand. A complicating factor in choosing the optimal harvesting period is the extended flowering and ripening period of goat’s rue beans, the duration of which reaches 25-35 days. The use of the drug Reglon Super based on diquat is a highly effective agrotechnical method that allows increasing the collection of seeds by 24%. The desiccation of the herbage contributes to the production of seeds with high sowing qualities. The seeds with the best sowing qualities are found in beans with yellow, brown, brown or dark brown color of the beans. In light green beans, the seeds are fully formed, but have a high moisture content. Goat’s rue beans do not crack or crumble at the onset of the full ripeness phase. This allows the seed to be harvested when most of the beans are ripe. A comparative assessment of the timing and method of harvesting the seed herbage of the goat’s rue showed that with a ripening of 39% and the presence of 47% of light green and yellow beans, the yield losses ranged from 26 to 56%. The highest seed yield in one confidence interval of 422-453 kg / ha and 444 kg / ha was obtained, respectively, by direct threshing with preliminary desiccation of the grass stand in the ripening phase of 74-97% of beans or by separate harvesting when mowing into swaths during ripening 74 % beans.
