Model tehnologic de pregătire, stocare și valorificare a gunoiului de grajd amestecat produs în gospodăriile populației rurale

Abstract

The article reflects the key points in the use of mixed manure from different species of animals and birds as organic fertilizer in agriculture. The technological model for the evacuation, storage and administration of the manure was developed based on the results of field experiments in the period 2010-2019. Mixed manure contains on the average 56,1% water, 18,4% organic matter and 25,5% ash. Compared to the cattle manure with bedding (conventional) the mixed manure contains 1.21 times more nitrogen, 1.32 times more phosphorus and about 7% more organic matter. The application of 22 t/ha of mixed manure during four years ensured a specific annual income per 1 ton of manure of 67 MDL. The specific income per 1 MDL spent was about 1.03 MDL.
