Nontraditional organic fertilizer: lignin – poultry manure – bark – cattle manure and lignin – bark – mineral – cattle manure are made from waste of the timber industry (bark, lignin) and livestock (cattle manure, poultry manure), by biothermal composting with careful stirring of the mixture components. The influence on the humus condition, acidity, water-physical and agrochemical soil properties, crop yields and agroresource potential was studied. The object of the research was reclaimed low-fertile medium loam alluvial soil of the Delta of the river Northern Dvina. Introduction of fertilizers in the norm of 100 t/ha contributed to the increase of humus content from 1.87% to 2.02-2.14%, mobile phosphorus - from 69 to 78 mg/kg of soil, exchangeable potassium - from 70-73 to 112-143 mg/kg of soil and to reduce the density of the plow layer from 1.31-1.36 to 1.26-1.27 t/m3. Organic fertilizers both in action and in the aftereffect optimized water-air regime, agrochemical properties and improved crop yields (of perennial and annual grasses) by 46-51% in the year of fertilizer application and by 8-15% in the third year of aftereffect. It affected the increase of the agroresource capacity of the soil, expressed in grain units, by 31-32% in an average per year.
