Approach for nitrate balance in the soil solution under fertirrigation.

The use of fertirrigation brings inputs o soil solution that affect solute dynamics and nutrient balance in the soil etted volume.This work has s objective to present an approach for nitrate balance in the soil wetted volume under drip irrigation from readings of electrical condutivity and soil water content using TDR technique. The approach uses a balance for nitrate in he soil solution, based upon the fact that he transport of nitrate is solely convective. Ion concentration is etermined based on a combination of an empirical model for estimating soil solution electrical conductivity (ECw) and a potential model that relates ECw and nitrate concentration in the soil solution.The approach has given satisfactory results,although the absolute values of the estimated dependent variables of the model may not stands for the real values in the soil.However,it can used for analyzing different components of the nitrate balance in the soil (uptake,leaching,infiltration) among fertirrigation events.
