Beneficios y costos ecológicos de sistemas de laboreo en el largo plazo. Estudio de caso en el SO bonarense, Argentina

Abstract

The aim of this paper is to quantify economically environmental impacts on soil quality resulting from the implementation of alternative tillage systems: conventional tillage versus no-tillage system. The analysis is developed in a farm located in southwestern Buenos Aires, Argentina, for the period 1986-2008. We quantify in economic terms the balance of nutrients by the replacement cost method; and there are assessed the environmental services of both practices using an adjusted production function that consider their physical production. We conclude that no-tillage system has a better performance from the studied perspectives, especially at low rainfall and levels of nitrogen scenarios.
