Abstract

Following the 25-year intensive fertilisation practice in the country, two-thirds of Hungarian soils became well or very well supplied with phosphorus (P) and potassium (K). As a consequence of both political and ecological changes in the late 1980s and early 1990s, fertiliser subsidies were withdrawn, and nitrogen (N) use has dropped to one-fifth, one-third, P and K use to one twenty-fifth, one-twentieth of the amounts used in the early-mid 1980s. An enormous demand has risen for a new, cost saving, and environmentally friendly fertiliser recommendation system. The new system based on the results of the published long-term field trial data in the period of 1960-1995 faces the new challenges.
