Soil fertility management: An agroecosystem approach

Soil fertility management is considered with respect to its determinants-delimiters (resource-related, biological, ecological, and economic). Four modules are suggested for soil fertility management: spatial and functional structure of an agroecosystem, regulation of interactions within the plant-soil system, system of soil cultivation, and the system of fertilization and plant protection. The fertility management objective is to ensure food security as an essential condition for creating a sustainable society.
