Comparative Animal Hygiene Assessment of two Technologies for Buffalo Manure Processing
The Organic crop production is one of the main pillars of development of the agriculture in Bulgaria.Regulation No.22/ 2004 of the MZG offers the opportunity to improve soil fertility through the use of organic fertilizers.which are processed by fermentation or composting.The purpose of this paper is to explore the use of two regulated in Ordinance No.22 byproducts of the processing of fertilizer-compost,obtained after methane fermentation,and composting.After laboratory experiments and mathematical modeling,the optimal technological parameters were found to be dry matter content of 7%,mesophilic temperature range of 330 Celsius and time of degradation of organic matter 49%-51% for 15 days.An assessment is made of the qualities of the methane fermentation byproduct(compost)and compost by physiochemical parameters,nutrient content of macro and micronutrients,and opportunities to use it to improve soil fertility.
