Nitrogen turnover in the soil-crop system; comparison of fourteen simulation models,hods of process description, as well as the results of simulations carried out with the same data set. It is concluded that simulation of the aboveground processes was less problematic than that of the belowground processes. None of the models could account for the loss of mineral nitrogen occurring

Modelling of the nitrogen cycle in farm land areas, leached nitrate, the main inputs into a model of transfer in aquifers. The processes of the N cycle included here are: mineralization, nitrification, ammonium adsorption-desorption, immobilization of N from ammonium and nitrate, N uptake by plants and leaching of nitrate. The results of a limited t

Nitrate leaching and soil moisture prediction with the LEACHM model,op from February to April in two years and three locations. The model grossly overestimated soil water content, probably due to the bad fitting of the assumed water retentivity function to the experimental data at high water contents, and to the presence of a relatively shallow water table (1.0–1.5

Some results of nitrogen simulations with the model ANIMO,IMO simulations of the hydrological conditions in the soil crop ecosystem were executed with the model SWATRE. Compared with measured data the simulation of nitrogen uptake by the crop was satisfactory. The simulation of mineral nitrogen in the soil agreed reasonably well with measured data for one

The distribution of water and nitrogen in the soil-crop system: a simulation study with validation ction of water and nitrogen deficit effects on crop growth and yield. Mathematical descriptions of these processes, based on the findings of detailed studies, were used as part of a larger simulation model to calculate the extraction and uptake of water and nitrogen, and the distribution of nitrogen

Simulating water and nitrogen behaviour in soils cropped with winter wheat,reatments. The experiments were monitored at three different locations on different soil types in the Netherlands. Crop growth was simulated using the SUCROS model which was integrated in the SWATNIT model. Both water and nitrogen stress were incorporated. Except for the soil hydraulic properti
