Abstract: The dynamic development of the pig industry in Russia is associated with an increase in the production of waste requiring efficient disposal. Among them, animal excrement occupies a leading place, containing a significant amount of mineral nutrition elements, which makes them a valuable type of fertilizer for most agricultural crops. Within the framework of this work, in order to identify the economic features of the use of pig manure, a comprehensive assessment of the effectiveness of applying various fractions and doses of organic fertilizer in the conditions of fodder crop rotation was performed. Manure of various fractions (initial, solid, liquid) for field experiments was taken from enterprise Zavolzhskoye of the Tver region and was introduced in the field experiment on the basis of the Tver State Agricultural Academy in the system of autumn soil preparation before the crop rotation starting (1. Annual herbs; 2. Winter rye; 3. Barley). It was found that the introduction of fractions of pig manure in doses of 100 and 200 kg / ha of the active substance nitrogen allows to obtain an increase in the yield of fodder crops in value terms up to 40 thous. rub./ ha at the level of additional income up to 25 thous. rub./ha and recoupment of application costs up to 3.06 rub/rub. In descending order of effectiveness, the fractions of manure were placed as follows: solid → liquid → initial. At the next stages of the work, it is supposed to study the feasibility of using composted fractions of pig manure.
