The models are based on calculating the coefficient of moisture deficit in the soil or the coefficient of moisture content (for April) — predictors. The following factors were used as predictors in pedotransfer models: the amount of precipitation during the growing season; soil moisture coefficient in April; Hydrothermal coefficient; coefficient of normalized atmospheric precipitation for the cold period; humus content in the layer 0-20 cm; soil washout coefficient; the bulk density of the soil in the layer 0-20 cm; height on the profile; coefficient of protective action of forest belts; coefficient of agrobackground. The initial information is a systematized set of data — hydrological characteristics of agricultural landscapes and soil properties, partially published by the authors earlier in the guidelines. The method of pedotransfer modeling of soil moisture supply on slope lands includes sequential mathematical and statistical analysis (using GIS technologies) according to the following thematic stages: (i) selection of factors affecting soil moisture supply as predictors of pedotransfer models; (ii) cluster analysis of the efficiency of soil moisture supply factors in the catchments of the agricultural landscape; (iii) development of pedotransfer models of soil moisture supply based on fragments of the growing season of crops by constructing regression equations and assessing the adequacy of the models by statistical criteria. The models are developed taking into account the phases (periods) of organogenesis of crops and the sequence of agrotechnical measures in the soil protection system of agriculture. It was found that among the studied factors, the most influential factor in predicting the soil moisture supply in any period is the agrophone factor, the share of which in different models ranges from 46 to 89 %. At the same time, the share of the influence of the natural factor of humidification — the Hydrothermal coefficient, is limited to the range of 10–17 %. It is shown that according to the results of predicting the moisture deficit in the soil, the territory of the agricultural landscape can be conditionally divided into working areas for the development of a differentiated system of practical agrotechnical measures to correct the supply of plants with productive moisture.","PeriodicalId":189346,"journal":{"name":"Agrochemistry and Soil Science","volume":"112 28","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131914411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the research is to identify the features of the effect of radiological load on the quality of agricultural products in fertilized and non-fertilized areas by measuring the specific activity of radioactive 137Cs in the dry phytomass of collected herbs, the density of soil contamination and calculating the coefficients of the transfer of radionuclides from soil to pasture fodder. The activity of 137Cs in plants was determined by gamma spectrometer. The introduction of increased doses of potash (K120) and phosphorus fertilizers together with potash (P60 K120) was effective in reducing the activity of radiocaesium in the dry mass of feed. Over the three years of research on the variant with potash fertilizers, a decrease in 137Cs activity in the feed by an average of 2.9 times was recorded, and at the site of the combined application of potash and phosphate fertilizers – by 2.7 times compared with the control variant of the experiment (without fertilizers).","PeriodicalId":189346,"journal":{"name":"Agrochemistry and Soil Science","volume":"167 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129049702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Monitoring and conservation of soils as a component of a sustainable management for agroecosystems at the local level","authors":"Y. Dmytruk, V. Semenchuk","doi":"10.31073/acss92-03","DOIUrl":"https://doi.org/10.31073/acss92-03","url":null,"abstract":"The article assesses the prospects of local and regional agroecosystems to provide modern measures to improve the quality of land and soils. The authors applied the analysis (induction and deduction) of guiding and normative documents and current publications of both Ukrainian and European on the organization of sustainable use of soils and the priority of their protection. It is important to remember, that the United Nations (U.N.) sustainable development goals (SDGs, indicator 15.3.1) have land degradation neutrality by 2030. A serious aspect of the article is the assessment of the possibilities of Ukrainian agriculture to implement a system of sustainable soil management at the local level in the near future. It is determined that drivers for soil management of agroecosystems, which determine the agenda for all land users and landowners are follows: (1) global processes and geopolitical significance of agriculture; (2) characteristics of soils as a natural object, in particular, their irreplaceability, non-renewability and performance of global biosphere functions; (3) national features, including the lack of real monitoring, gaps in legislation and non-compliance with existing regulations and acts and the land market. Therefore, there is a need for precise legislation to protect and preserve soils, as well as the implementation of agricultural technologies that will ensure a land degradation neutrality and soil sequestration of carbon. Given the uncertainty about the functioning of real soil monitoring at the state level, we consider it promising to organize soil monitoring as a local network. This means that the creation of a components of a specific soil management system should be provided by land users. The authors are convinced that experimental stations in the structure of NAAS should maintain / create their own database. Based on such a database it will be possible to effectively ensure sustainable soil management, namely: to assess soils current state at the moment, ecosystem services from soils, to predict the dynamics of soil indicators, to simulate different variants of their changes and so on. The costs of such a local GIS are offset by gains, including profits from business activities for many years to come. Due to the increased attention to soil organic carbon reserves (introduction of carbon taxes, restrictions on greenhouse gas emissions), it is urgent to assess and forecast the processes of carbon emission-sequestration and appropriate soil capabilities for a particular type of land use. Soil scientists are ready to develop a method of data collection and local GIS, taking into account the specifics of the type of agriculture.","PeriodicalId":189346,"journal":{"name":"Agrochemistry and Soil Science","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127038141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Statistical models — regression equations for determining temporary changes in the studied indicators are developed. Statistical analysis was carried out and patterns of dynamics of parameters of hydrothermal indicators were revealed within the framework of such stages: year, growing season; sowing periods of spring crops (April); harvest formation (May-June); post-harvest (July–August); sowing of winter cereals (September-October); cold period (November-March). A general trend towards an increase in the average annual precipitation and a high variability (CV > 25%) of the average monthly values in certain stages of the growing season were revealed. Probabilistic analysis of long-term data, using the method of constructing empirical and theoretical (analytical) security curves, revealed that the average monthly temperature during the sowing periods of early spring and winter crops 11-14 ℃ corresponds to 10% probability level, and 8.0–11.5 ℃ — 50%. In the same period, precipitation of 58-60 mm corresponds to a 10% probability level, and 30-40 mm corresponds to 50%. By analyzing the angles of inclination of trend lines, the dynamics of the average monthly values of precipitation and air temperature in the study area was studied and the distribution of the rate of increase or decrease in precipitation and temperature change was obtained. The generalization showed that the angle of inclination of trend lines is associated with the stage of the growing season. Fluctuations in average monthly temperatures correspond to fluctuations in the average monthly precipitation and are most noticeable in the periods of early spring sowing, crop formation and post-harvest. The average annual temperature in 1845-1935 on the territory of the region it is kept at the level of 8 ℃, and from 1935 to nowadays time it has been steadily increasing to 10 ℃. The revealed features of changes in the amount of precipitation over time can be used for further studies of the unevenness of atmospheric soil moisture, flood forecasting, changes in erosion activity, and the like.","PeriodicalId":189346,"journal":{"name":"Agrochemistry and Soil Science","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114091344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The soil cover of one of the fields is made up of Chernozem podzolized (Chernic Phaeozem) in combination with Dark gray podzolized soil (Luvic Greyzemic Phaeozem), and the second field is Chernozem typical (Haplic Chernozem) with eroded and highly moistened varieties. Each field was divided into 24 plots, from which mixed soil samples were taken from 7 individual samples from a layer of 0–30 cm twice a season – in April–May and in October–November. On the soils of the podzolized row, a high amplitude of fluctuations in the pH values of salt was found during 3-year observations – from 4.4 to 5.2. As a result, the parameters of soil saturation with mobile phosphorus, determined by the methods of Chirikov and Machigin, were significantly different. In a field with chernozem, the typical measurement results for both methods were similar. The results of the analysis of the content of mobile phosphorus in the soils of the field according to the average values of the aggregate of individual samples did not show significant seasonal differences. However, on each of the fields, there were separate locations with higher values both according to the Chirikov method and the Machigin method, regardless of the sampling season. Along with this, in both fields there are locations where two methods of determination show different trends in the spatial distribution of the content of mobile phosphorus, which indicates the artificial nature of such heterogeneity. This confirms the hypothesis about the presence of a stable and temporarily artificial component of the spatial heterogeneity of the phosphate state of soils.","PeriodicalId":189346,"journal":{"name":"Agrochemistry and Soil Science","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116918657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are various methods developed for pH measurement, although we using only distilled water from the beginning. In Nepal, there do not have database for showing performance of the methods. The three methods namely; H2O, KCl and CaCl2 with their soil:solution ratios (1:1, 1:2 and 1:2.5) were used. The total 115 samples were collected randomly at a depth of 0-20 cm from the hill and terai regions of Nepal. The collected samples were analyzed following mentioned methods, separately. The various statistical tests (F-test, mean separation, correlation, and regression model) were performed for comparison. Moreover, model validation parameters were also calculated for relating H2O with electrolyte method. The three models linear, quadratic and cubic were used for this task. The result revealed the effect of methods on pH measurement was significantly different in the entire ratio. The pHH2O was 0.57, 0.56 and 0.67 units higher than pHCaCl2 in 1:1, 1:2 and 1:2.5 ratios, respectively. Whereas, 1.24, 0.99 and 0.95 units higher than pHKCl in respective ratio. Moreover, regarding timing to reach stable during measurement were in the order pHH2O (89.44 sec) > pHCaCl2 (54.29 sec) > pHKCl (33.08 sec). Similarly, relating modeling quadratic and cubic model showed nearly equal performance (lower RMSE, MAE and higher R2 and d) for predicting pHCaCl2 and pHKCl from the pHH2O in each soil solution ratio.

The study was carried out on two fields in the Kharkiv region in the zone of the Left-Bank Forest-Steppe of Ukraine. The soil cover of one of the fields is represented by gray forest (Haplic Luvisol) and dark gray podzolized (Luvic Greyzemic Phaeozem) soils, the second – by podzolized chernozem (Chernic Phaeozem) (including reclaimed) and dark gray podzolized (Luvic Gremizem) with eroded counterparts. According to the granulometric composition, all soils are heavy loamy. Relationships were found between the main indicators of soil fertility and the characteristics of the relief of the surveyed land plots, cartographic materials were created for the spatial distribution of nutrients using statistical methods of data processing. The existence of spatial heterogeneity of soil properties (Cv > 25 %) was confirmed and factors influencing the features of their spatial distribution were determined. It was found that the existence of heterogeneous landforms and, in particular, the presence of microdepressions in the surveyed areas, causes an uneven distribution of precipitation, which significantly affects the formation of heterogeneity of soil quality within the field – the content of nutrients (nitrogen, phosphorus and potassium) and soil pH. The results show that the soil at high relief points and in micro-depressions is better provided with humus and available phosphorus compounds. The zones of available potassium and nitrogen enrichment coincide with depressions in the relief. The reason for the distribution of nutrients is the migration of flows of substances, the intensity of which depends on the topographic features of the territory. It was found that the soil at higher parts of the field is characterized by pHH2O values close to neutral. Relative acidification of the soil was found in areas with a sharp slope of the surface.

It is known that the irreversible annual soil loss under the influence of water erosion on average in the Polissia zone is 7.6, in the Forest-Steppe zone – 7.8, in the Steppe zone – 3.3 t / ha. It is shown that the erosion component in the part of humus losses approaches 40 %, strengthening the negative part of the balance. To obtain the most correct information on the humus balance in soils, a differentiated approach to balance models is recommended. At the regional territorial level, to calculate the predicted losses of humus because of erosion, the value of the average slopes on the arable lands of the administrative region, the average values of soil washout at specific slopes and soil and climatic conditions were used. It is proved that the calculation of the humus balance under individual agricultural crops, or in the crop rotation should include the average, in the administrative region, humus losses caused by water erosion, which differ significantly by regions in the soil and climatic zones of Ukraine (from 154 to 1700 kg/ha). According to the total losses of humus from water erosion, 3 groups of territories were identified: I – from 50 to 100 (South Steppe), II – from 140 to 200 (Polissia, Left-Bank Forest-Steppe and Northern Steppe), III – from 200 to 300 kg/ha (Right-Bank Forest-Steppe). In areas where there is a threat of deflation, the loss of humus caused by wind erosion, which in the southern part of the country ranges from 293 to 1700 kg/ha, significantly affects the humus state of the soil and should be included in the calculations of the humus balance along with the data on water erosion.","PeriodicalId":189346,"journal":{"name":"Agrochemistry and Soil Science","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130702108","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main problems in the modelling of organic carbon reserves for the territory of Ukraine have been identified, among which: lack of high-resolution data (hard to access), including types of land use; need for harmonization of existing data; the need for predicative modelling of indicators (clay and organic carbon content) for areas where data are not available; significant amounts of machine time for actual modelling. The need for open access to archived data (technical reports) from large-scale soil surveys 1957-1990 is highlighted. Also, the need to access large-scale topographic data as in the form of scanned topographic maps M 1:10000 and vectorized isolines are substantiated. It is shown that calculations of areas based on rasters in the geographical coordinate system to ensure the same pixel size, regardless of the location within Ukraine, it is proposed to use the “Ukraine Albers conic equal area” projection based on the Datum Pulkovo 1942 for which the error in the lengths of the lines is only 0.1%. Within areas can be used as a proposed projection, as well as precise Gauss-Kruger projections (EPSG 28404-28407, 5565-5583). In this case, it is necessary to take into account the likelihood of finding individual areas in several of the listed zones. It is demonstrated that simulation allows to establish territories in which even the best practices of management do not provide neutralization of emission of organic carbon from soils. However, it is necessary to introduce a priority introduction of adaptive management of the soil resources of agro-landscapes that will contribute to carbon sequestration or minimization of its emission.","PeriodicalId":189346,"journal":{"name":"Agrochemistry and Soil Science","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130040251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
