Uso racional de recursos naturais não-renováveis: Aspectos biológicos, econômicos e ambientais

Abstract

Due to limitations of new land areas for agriculture, its development has being based on increase in productive indexes in animal and plant production. However, negative effects have being emerged, as excessive utilization of non renewable natural resources and environmental pollution. The objective of this work was to demonstrate the possibility of use of models of saturation kinetics in agriculture (plant and animal production) to improve efficiency of use of non renewable natural resources, avoid complete depletion of them and minimize the problems related to environmental pollution. © 2009 Sociedade Brasileira de Zootecnia.
