摘要：
The paper presents results of studying chalking efficiency of leached black soil when cultivating spring wheat in the conditions of the forest-steppe of the Volga region. It was established in field experiments that liming of leached black soil significantly reduces soil acidity: exchangeable by 0,21-0,38 pH(KCl) units, hydrolytic by 0,22 -0,41 mg / kg of soil depending on the application dose (2-6 t / ha) in the first year. Improvement of soil medium in terms of acidity contributed to an increase in the yield of spring wheat by 0,18-0,20 t / ha in case of using chalk in pure form and by 0,17-0,28 t / ha in combination with NPK, in farm conditions by 0,4 0,8 t / ha.
