N-Tester - the easy & efficient way to measure leaf N
The nutritional status of the plants determines the timing and amount of fertiliser. With the N-Tester it is possible to identify the nitrogen requirements of plants directly on the field easily, safely and quickly. The nitrogen fertiliser demand is never constant and can vary considerably from year to year and field to field. By splitting the N-fertilisation into more dressings, it is possible to optimise the N-fertiliser rate according to the actual plant's needs on any field in any year.
A plant analysis with the N-Tester gives valuable information about the current nutritional status of the plant. In cereals from this measurement, the optimum N-fertiliser amount at ear emergence can be calculated.
