Patterns of Formation of the Soil Resources Diversity in Delta Ecosystems
Researchers conducted in various regions are devoted to studying the resource potential of soils and substantiating the importance of soil resources in the production of food products. The main attention is paid to the spatial parameters of soils and the distribution of their ranges across continents, regions and the determination of the areas of existing soils per capita. It is generally recognized that the existing areas of soils are depleted and the land areas are limited in geometric shapes. To increase the biomass of plants used for the production of food products, it is necessary to study the primary tasks - to study the diversity of categories of soil resources, and, first of all, bioproducts. Inexhaustibility is characteristic of bioproduction resources, the potential of which is determined by the use of solar energy and the increase in photosynthetic activity of plants (FAR). The revealed regularities of the change in the threshold concentration of nutrients and the ratio of litter to increment make it possible, under the condition of using fertilizers, to form a phytocenosis, providing a dominant position to fodder plants with high productivity.
