Influence of the fertilizer system and humus content in a soil on the quantity of gross phosphorus, mineral and organic phosphates, mobile phosphorus in humic acids has been shown. The application of the organic and mineral fertilizer as well as the increase of the humus content from 1,2-1,6 to 3,0-3,6 % promotes to increase of the above-mentioned indexes. The further increasing of humus content up to 7,0-10,0 % rises the gross phosphorus content, organic phosphate quantity and mobile phosphorus in humic acids and decreases the mineral phosphate content
