Simulation of the nitrogen balance in the soil and a winter wheat crop,dry matter production agreed with measurements, nitrogen uptake was simulated accurately. The total amount of soil mineral nitrogen as well as the distribution of mineral nitrogen over the various soil layers were generally simulated well, except for experiments in which fertilizer was applied late

Simulation of nitrogen in soil and winter wheat crops: a management model that makes the best use oo that it is useful as an aid to management. The adapted model, which was developed in the UK, was tested against data from six experiments on winter wheat in the Netherlands. It proved reasonably successful in simulating the amounts of mineral N found in the soil in early spring and the changes tha

Modelling water flow, nitrogen uptake and production for wheat, depths from one site with a sandy loam soil indicated bypass flow in macropores. Nitrogen turnover was simulated using the output of SOIL as input to a nitrogen model. To improve the nitrogen model, a crop-growth submodel was introduced, and simulations were compared with measured data for two seas

,A comparison of the performance of N simulation models in the prediction of Nmin on farmers’ fields predict N. content in the spring under cereal crops. The models of British, Dutch and German origin, were tested using data from farmers’ fields supplied by 70 farmers over two growing seasons in FRG. The models were run between harvest of the previous crop and spring of the following year, and pre

Response of wheat to nitrogen fertilization, a data set to validate simulation models for nitrogen esting simulation models for soil nitrogen dynamics, crop growth and nitrogen uptake. Each experiment comprised three different nitrogen treatments, and observations were made at intervals of two or three weeks. The observations included measurements of soil mineral nitrogen content, soil water cont
