Modelling of seasonal dynamics of nitrogen, phosphorus and potassium in the rooted zone

Abstract

A Hungarian CERES based model (4M) was used for modelling the seasonal changes of the available nutrients in the soil, and the dynamics of the whole nutrient balance. Changes of soil moisture content of the profile has also been measured and simulated. These data are key for any modeller to test the capability of a given crop model. 4M performed well in estimation of water and nitrogen dynamics. Phosphorus and potassium dynamics are more complicated in nature. Availability for plant uptake is a difficult question to follow and even so to measure. The results certainly give a step forward in modelling of P-and K-cycles.
