Abstract

Application of livestock wastes during three years has exerted generally positive influence on humus storage. Pig effluents application assisted in storing the total forms of nutrient elements in comparison to the bench-mark data and control. The more significant storage of nutrient elements in soil and certain increase of organic matter content has been witnessed during the increase of the rate of livestock wastes application from 100 to 300 m3/ ha. A mathematical model reflecting the dynamics of humus reserve by means of livestock waste and plant residues humification and considering humus waste has been developed. The adequacy of the model was analyzed with regards to the data obtained as a result of watering with pig effluents in the meadow-steppe area of Togulsky region in Altai Krai, Russia. The mathematical model has gained high evaluation of approximation accuracy. The approximation error is 6%. The estimate of annual irrigation by pig effluents during 20 years at the rate of wastes equal to 300 m3/ha has indicated the 1.21 times increase of humus reserve from 146.858 ton/ha to 177.87 ton/ha; while the content of non-humified organic matter will increase during 7 years in soil up to 1.19 ton/ha and then the content will stabilize. The 20 year forecast with the irrigation with pig effluents with the norm 300 m3/ha has shown the negligible storage of non-humified organic matter of pig effluents in soil
