In arid and semi-arid areas, timely and effective monitoring and mapping of salt-affected areas is essential to prevent land degradation and to achieve sustainable soil management. The main objective of this study is to make full use of synthetic aperture radar (SAR) polarization technology to improve soil salinity mapping in the Keriya Oasis, Xinjiang, China. In this study, 25 polarization features are extracted from ALOS PALSAR-2 images, of which four features are selected. In addition, three soil salinity inversion models, named the RSDI1, RSDI2, and RSDI3, are proposed. The analysis and comparison results of inversion accuracy show that the overall correlation values of the RSDI1, RSDI2, and RSDI3 models are 0.63, 0.61, and 0.62, respectively. This result indicates that the radar feature space models have the potential to extract information on soil salinization in the Keriya Oasis.

The environment is changing quickly and it is ever more burdened in connection with the greater needs of human society. This fact has increased efforts to improve the management of land and natural resources and the necessity to evaluate them. Land valuations become more important as the land consumption increases. Soil needs to be evaluated in the whole context of how its quality is affected and the values it provides. The concept of ecosystem services offers this holistic view. This paper defines ecosystem services (ES), the various linkages between soil properties, their functions and benefits, the assessment of soil quality using indicators and then briefly mentions EU environmental assessment methods and terms used in the context of ES. The article also mentions frameworks with which to assess and evaluate the soil quality that can be divided into two groups. The first group is comprised of a framework of indicators that describe the current state of the soil system assessment for evaluating the quality of the agricultural land. This is based on a detailed measurement of the terrain, a statistical analysis of soil databases or processing the status of specific threats to the soil. The second group is comprised of a framework of indicators focused on changes in the soil quality and applied soil management. These frameworks deal with the productivity of the soil in various systems of farming, compare agricultural systems or discuss the advantages of soil biota as indicators of soil quality in detail. Many of the designs of the soil quality indicators focus on the soil management in the context of a single discipline such as agriculture or water pollution. There are concepts for considering the soil quality in regional planning.

<p><em><strong>Soil Ecology Training and ToT for Strengthening Organic Agriculture in Al-Barokah and Walisongo Farmer Groups in Ketapang Village</strong>. </em>In sustainable integrated agriculture, farmers are expected to be experts in managing agricultural ecosystems. To support this, training and empowerment of sustainable agricultural management can be carried out for farmers. The process of soil ecology training and training of trainers (ToT) is directed at strengthening organic farming and it is hoped that farmers can play a role as a farm manager, able to stand parallel and have an active relationship with the community and have a role in the system built by the community. Therefore, it is proposed the title of PKM-Training and ToT of Ecology Soil for Strengthening Organic Agriculture. The purpose of training and soil ecology ToT for strengthening organic agriculture is to increase farmers' understanding of the importance of ecology in soil management that has been applied so that there is renewal in soil management and building farmer knowledge. Through the Participatory Action Program approach, the Al-Barokah and Walisongo Farmer Groups farmers are very enthusiastic, which is indicated by an increase in understanding of soil ecology. Training and soil ecology ToT for farmers is very important so that soil management is in harmony with nature and increase the understood that soil ecology is part of the global ecosystem, and soil ecology is a process of interaction between ecological components on the level of fertility and crop production.</p>

The article provides a brief analysis of the results of plot and field experiments to study the productivity (yield) of sunflower, depending on the area of plant nutrition, performed at VNIIMK. Based on the analysis of the experimental dependencies that determine the change in yield, the following statement is applied: yield (y) and its increase rise with an increase in the amount of growth factor (x) and are proportional to the amount of yield (A - y) that does not reach the maximum the limiting value (A), and the possible yield value (B + y), is higher than a certain minimum (initial) value (B) of the yield. The analytic formulas for the quantitative determination of yield value (у), maximum limiting yield (A), amount of nutrients in soil, a rate of action of growth factors, etc. are present for the first time. These formulas allow studying many problems of soil management in certain hydro-temperature conditions and landscape. The samples of accounts due to the new methodology which showed good correspondence between test and theme data are presented.
