This work presents the analysis of the effect of compost addition on leaching of mineral nitrogen from arable land, plant biomass production and soil properties. Compost used for experiment consists of the basic raw materials for the production of reclamation substrates in company CKB. These substrates are often used for restoring the damaged agricultural lands. Therefore, this compost was applied in increased doses (300% of recommended dose) to determine the potential impact on the parameters above. To demonstrate this effect, five variants with same doses of compost and different doses of mineral and organic fertilizers, were prepared. The highest decrease of mineral nitrogen leaching was observed by the simultaneous applications of soluble humic substances and compost to soil samples, about 400% in comparison with the control variant.
