    A PRELIMINARY ANALYSIS OF AN ECO-AGRICULTURAL SYSTEM OF AN UNITED PRODUCTION UNIT

      Graphical Abstract
      • Abstract
    • Shucture,functions and effects of agroebosys tem were studied quantitatively for an united production unit of several households. Energy analysis and nutrient cycling estimates showed an encouraging effect of food processing subsystem on animal husbandry and food-grain production with a sustained increase of soil fertility. System input was predominantly from bioenergy,rather than from fossil-fuel source. The unity of economic, social and ecological effects’indicated the advantage of the human-manipulated agroecosystem with crops,livestocks and food-processing as 3 subsystems.
