Soil Resource Diversity and Its Role in Food Security Preservation

摘要

This paper shows the expediency of using the cartographic method for assessing soil resources by area with the addition of resource diversity (production, energy, and information resources). It studies the genetic nature of a production resource, which is an important category of diversity. Ratios are revealed for the values of annual growth and plant litter and the share of total biomass reprocessed into food; the threshold concentration of nutrients and competitive relations in their consumption act as factors of mobilization of unused resources.
