New environment-friendly and cost-saving fertiliser recommendation system for supporting sustainable agriculture in Hungary and beyond

摘要

In the current economic situation the former, intensive fertiliser recommendationsystem is unfit to help Hungarian farmers in their fertilising practice. The aim of thenew system has been to apply the lowest possible NPK rates required to achievesafe and high yields as well as allowing minimal agricultural NP losses to surface andsubsurface waters. The new system was developed by using the correlationsrevealed by analyzing the results of long-term fertilisation experiments set up inHungary between 1960 and 2000. Several field experiments as well as comparativeanalyses confirmed the correctness of the basic principles as well as of the methodsof 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 formore than 160,000 ha arable land applying the new system.
