Abstract:

The long-term use of high mineral fertilizer rates, aimed at intensifying the plant production, causes the process of soil acidification, resulting in the decrease of the yield of grown plants, due to increased contents of aluminium and manganese and decreased contents of organic matter and basic cations in the soil. In order to eliminate or reduce these harmful effects trials were set up and different materials for the neutralization of acidity and the excess of mobile aluminium were used: bentonite, zeolite, crude phosphates, MgO and CaO.
