METHOD FOR PREDICTION OF NITROGEN PRESERVATION LEVEL DURING UTILIZATION OF LIVESTOCK BREEDING WASTES ON THE WHOLE TECHNOLOGICAL CYCLE

摘要

FIELD: agriculture.;SUBSTANCE: invention relates to the field of agriculture (agroengineering ecology) and is intended for the nitrogen level safety forecasting during the livestock breeding wastes utilization that is necessary for the livestock enterprises functioning ecological safety level estimation, assessment of potential modernization of existing enterprises, as well as selection of rational technologies for utilization of livestock farming wastes for newly created enterprises. Method for prediction of level of nitrogen conservation during utilization of livestock waste by whole process cycle comprises sampling initial waste, in which it is determined: water content by thermostatic-weight method, content of total nitrogen by Kjeldahl method, content of total carbon by Tyurin method, nitrogen level is determined on the whole process cycle by formulas.;EFFECT: invention will make it possible to increase reliability of prediction of level of preservation of nitrogen during utilization of livestock breeding wastes on the whole technological cycle, including operations of processing, storage, transportation and introduction into soil as fertilizer, and enables to predict nitrogen preservation level for wastes with water content less than and greater than 92 %.;1 cl, 5 tbl, 2 ex
