Abstract:

Today, climate change is exacerbating the problems of efficient and environmentally friendly use of acidic soils, which are widespread in Ukraine. At the same time, the role of mobile aluminium compounds in acidity formation is also becoming increasingly important. In this regard, chemical amelioration remains a primary and very important factor in the system of resource-saving and environmentally friendly agricultural measures for the efficient and balanced use of acidic soils. Therefore, the main objective of the research is to establish scientifically sound doses of chemical ameliorant that reduce the content of mobile aluminium compounds and ensure environmental safety and high productivity of agrocenoses on Albic Pantostagnic Luvisol. The research was carried out in a long-term stationary experiment established in 1965 with different doses of mineral fertilisers, manure and lime on an Albic Stagnic Luvisol. It was found that with a prolonged application of mineral fertilisers and the use of this soil without fertilisers, the content of mobile aluminium compounds at the end of the X rotation at pHKCl 4.20 and 4.42 was 68.4 and 58.5 mg kg-1 respectively. Under the organo-mineral and mineral fertilisation systems with liming with 6.0 t ha-1 of CaCO3 calculated by hydrolytic acidity, the content of mobile aluminium compounds decreased to 7.2 and 6.7 mg kg-1 of soil respectively. Under identical fertilisation systems with a lime application by pH-buffering capacity (2.5 t ha-1 CaCO3), the content of mobile aluminium compounds is 10.8–10.0 mg kg-1 soil.
