Simulation of nitrate and potassium concentrations in soil solution using parametric models and Hydrus-2D

This study estimated the nitrate and potassium concentration in soil solution of drainage lysimeter using mathematical models developed by Vogeler et al. (1996) Muñoz-Carpena (2005) computational model Hydrus-2D, while comparing simulated observed data statistical parameters. The cultivar used for was ‘Prata Gorutuba’. experimental plots were six lysimeters drainage. Fertigation performed weekly. to determine specific a given ion (Ci). Hydrus software simulate dynamics nutrients. concentrations (1996), adapted linear type CEw-Ci ratio model, resulting an acceptable characterization distribution these
