Sažetak
In the current economic situation the former, intensive fertiliser recommendation
system is unfit to help Hungarian farmers in their fertilising practice. The aim of the
new system has been to apply the lowest possible NPK rates required to achieve
safe and high yields as well as allowing minimal agricultural NP losses to surface and
subsurface waters. The new system was developed by using the correlations
revealed by analyzing the results of long-term fertilisation experiments set up in
Hungary between 1960 and 2000. Several field experiments as well as comparative
analyses confirmed the correctness of the basic principles as well as of the methods
of calculating fertiliser rates of the new system. An estimated amount of 3,200,000 €
was saved for the Hungarian farmers in 2007 alone by giving recommendations for
more than 160,000 ha arable land applying the new system.
