Manufactured by the method of dispersing organic sapropel humic fertilizer is the effective type of organic fertilizer and differs from manure of cattle higher maintenance of nitrogen, phosphorus and calcium, accordingly on 0,31, the 0,04 and 7,7%. Application of humic fertilizer in a norm equivalent to 15 т/ha of manure positively influences on the ecological state of grey forest soil, In particular to reduce the content of heavy metals in the plow and subsoil layers (lead, cadmium, copper and zinc). In experience after the third year of the use of such norm of fertilizer the increase of maintenance of humus substances is also marked on 0,07 and 0,09% respectively in the layer 0 – 20 and 20 – 40 cm in comparison with the control variant. Positive influence of humic fertilizer on the ecological state of grey forest soil stipulates the increase of the productivity of agrocenosis of triticale spring to 4,72 т/ha, that on 1,6 т/ha it was anymore by comparison to control. In a variant with the most norm of humic fertilizer the harvest of grain is got with the least indexes of maintenance of heavy metals. At all variants of experience maintenance of heavy metals in grain did not exceed possible concentrations maximum. |
