Abstract :

Maximal allowed nitrogen fertiliser rates for field crops in Latvia are limited by legislative acts and set up for different yield levels. The main objective for such limitation is to reduce the excess of mineral nitrogen left after crop harvesting. To monitor plant nutrient nitrogen requirements and to assess the possible nitrogen surpluses balance method was used. In field experiments with w ...
