Notes: Abstract A simple functional computer model for advisory purposes is described. Results of simulation indicate some limitations of the model especially in handling the water regime in soils with fluctuating water tables. A major problem seems to be the ‘disappearance’ of fertilizer N. Measurements by the fumigation-extraction method of microbial N during the growing season show that disappearance of fertilizer N can partly be explained by immobilization by the microbial biomass.
