Abstract
Objective. To study the effect of meliorant on changes in the content of total humus and its fractions in a weakly acid chernozem typical. Methods. Physico-chemical and agrochemical analysis of soil and plant samples and phenological observations on growth and development of plants have been carried out. Results The use of a defecate in the same norm of CaCO3, calculated on the basis of the hydrolytic acidity of the soil (4.9 t / ha in physical weight), combined with mineral fertilizers (N90P60K90) in the autumn under discarding of the stubble with subsequent stacking, increased the total humus content to 3.5% , Total carbon - up to 2.02% for the content of humic acids 0.49% of the weight of soil for the indicators in the control variants of the experiment: 3.3%; 1.91; 0.49% respectively. Conclusions The introduction of defecet obtained by the new technology contributes to the restoration of the processes of melioration and humification of organic matter in a weakly acid chernozem typical.

Key words: humus, liming, organic matter, chemical reclamation, chernozem typical.
