Animal Manure Components and Production of the Animal Husbandry in Anhul Province
摘要
Abstract
The contents of nutrients and heavy metals, including N, P, K, Pb, Cd, Cr, Cu, Zn, Hg and As, etc. in the manure of different animals were surveyed and tested in Anhui Province. According to the data in Anhui Statistical Yearbook, the total manure production from the animal husbandry in Anhui Province in 2008 was estimated. Results showed that the N, P and K nutrients contents in the animal manure in 2008 were 113 235,58 441 and 80 573 t, which equalled to 246 200 t urea, 1 115 900 t calcium phosphate and 161 800 t KC1, the N content accounted for about 18. 20% of the total maximum N carrying capacity of farmland in Anhui Province. The production amount of Pb, Cd, Cr, Cu, Zn and As was 72.59, 2.30, 125.97,977.96, 1 123.98 and 32.67 t, and that of Hg was 171.41 kg. However, the long-term application of animal manure in farmland may result in the risks of heavy metals exceeding the standards.关键词
