On methodology problems of developing innovative technologies taking into account anti-erosion measures

Abstract

The increase in world population and the decline in soil resources requires the increase in crop yields. Erosion and soil pollution are among the major threats to soil resources. With modern land use the rate of erosion exceeds the rate of soil formation. It is almost impossible to restore erosion soil loss. Soil pollution is a source of contaminated crop products and environment. In crop production innovative technologies are needed that must simultaneously solve three problems. The first problem is to ensure the necessary quantity and quality of crop products. The second problem is to preserve soil resources. The third one is to preserve the environment. In Russia, the increase in yields is mainly due to an increase in rates of mineral fertilizers, the use of plant protection tools and the use of varieties with a greater ability to utilize mineral fertilizers. In some regions of Russia, up to 70% of the arable land area is subject to water erosion of the soil. For the conditions of Russia, an analysis of the existing problems in assessing the long-term consequences of new technologies in crop production was carried out. Approaches have been proposed to solve some of the problems.
