The autor calculated the NPK balance for the years 1986-1990 and 1991-1995 on 6 million hectares of cultivated land in Hungary. By summarising previous studies, trends in nutrient balance were estimated for the period 1900-1995. It was found that during this century the N and K balance was only positive for 20 years, between 1970 and 1990, while the P balance was positive for 30 years (1960-1990), resulting in the accumulation of 800-1000 kg/ha N, P2O5 and K2O per hectare of soil. As a consequence of this, the P and K supplies in the soil, the yields, and the nitrification of the groundwater increased in the 70s and 80s. The deficiency in the nutrient balance and the rate of fertiliser application dropped in 1991-1995 to the level recorded 30 years earlyer. The author also formulates the tasks facing research, extension services and environmental protection in agriculture.
