To reasonably assess the potential utilization of cattle and sheep manure,this study adapted the essence of previous articles,basing on the nutrient content coefficient and research outcomes officially released by Agriculture Ministry of China in 2009,measured and calculated the potentialities of manure around China in 2013.Besides,converted standard coal,fertilizer (such as urea superphosphate,diammonium phosphate) were also calculated by the capacity of COD,TN (nitrogen),TP (P) rooted in the manure.Meanwhile,Linxia region was proved as the case study,which stands for the typical poverty county in the northwest of China.In Linxia region,the total amount of COD capacity from cattle and sheep manure was 48145269.74kg,which can converted into biogas coal equivalent 28176.82t.The total amount of TN and TP was 2557.18t and 256.40t respectively,which can be converted into equivalent fertilizer of urea (about 5559.09t) and superphosphate (about 4200.48t),or equivalent diammonium phosphate and urea of 1050.12t and 5.19t,respectively.The study shows that reasonable utilization of cattle and sheep manure both reduce the cost of farming and provide corresponding decision making for the poverty alleviation in northwest China.
