The plant growth and nitrogen uptake pattern of a crop with a short production period (iceberg lettuce) grown at two different periods in the growing season and a crop with a long growth period (gherkins) are analyzed in order to formulate an improved nitrogen fertilizer recommendation. A split fertilizer application which is tuned to the uptake pattern of the crop and the mineral content of the soil (0–30 cm) or the removal of nitrogen from the field. In this way it is expected that the fertilizer will be used more effectively and nitrogen losses by leaching will be prevented or decreased.
