摘要: Land application of livestock manure has caused concern about excess nutrients in soil and the potential risk to water quality. Application based on crop-nutrient requirements is considered a beneficial management practice. A field study was conducted assess feasibility impact crop-based N P rates cattle (Bos taurus) compost for crop productivity accumulation extractable P. The 6-yr (2002-2007), small-plot included 10 amendments: control (CONT), annual synthetic fertilizer (F-N), (F-P), plus (F-NP), N-based (M-N), P-based (M-P), three times once per 3 yr (M-3P), (C-N), (C-P), (C-3P). Amendments were arranged randomized complete block design with five replicates applied testing nutrient re...
