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.
