Abstract The excessive accumulation of animal manure in livestock production units has made manure a valuable phosphorus (P) source that if used efficiently can be a sustainable alternative to mineral P fertilizer. A two-year field experiment was conducted at Paterson, South Central Washington, to assess corn (Zea mays L.) grain yield, tissue P concentrations, soil quality indices and Olsen P test in soils amended with composted chicken manure, anaerobically digested dairy manure (AD dairy manure) and mono-ammonium phosphate (MAP). Treatments were applied using four rates. There was no significant grain yield and grain P response to fertilizer treatments. Corn leaf P concentration was significantly higher when application rate was twice (40 kg P ha−1) and four times (80 kg P ha−1) the recommended rate relative to the no-P control treatment. At these higher P application rates, leaf P from plots receiving composted chicken manure and AD dairy manure were comparable to leaf P concentration in the MAP treatment. Soil Olsen P test increased with application rate, although increases were not always statistically significant. Soil quality indices for both years did not differ significantly for the two-manure derived P sources vs mineral P fertilizer. These results suggest that changes in soil quality indices should not be expected change within 2 years of using manure derived P

厌氧消化乳粪和堆肥鸡粪对玉米产量、磷吸收和土壤质量的影响

摘要 畜牧生产单位动物粪便的过度积累使粪便成为一种有价值的磷（P）来源，如果有效利用，可以成为矿物磷肥的可持续替代品。在华盛顿中南部帕特森进行了为期两年的田间试验，以评估玉米（Zea mays L.）谷物产量、组织 P 浓度、土壤质量指数和 Olsen P 测试在用堆肥鸡粪、厌氧消化乳粪改良的土壤中（AD 乳制品粪便）和磷酸一铵 (MAP)。使用四种速率进行处理。施肥处理没有显着的粮食产量和粮食P响应。相对于无磷对照处理，当施用量是推荐施用量的两倍（40 kg P ha-1）和四倍（80 kg P ha-1）时，玉米叶磷浓度显着更高。在这些较高的磷施用率下，来自接受堆肥鸡粪和 AD 奶牛粪的地块的叶磷与 MAP 处理中的叶磷浓度相当。土壤奥尔森 P 检验随着施用量的增加而增加，尽管增加并不总是具有统计学意义。两种肥料来源的磷源与矿物磷肥相比，这两年的土壤质量指数没有显着差异。这些结果表明，土壤质量指数的变化不应在使用粪肥后 2 年内发生变化。两种肥料来源的磷源与矿物磷肥相比，这两年的土壤质量指数没有显着差异。这些结果表明，土壤质量指数的变化不应在使用粪肥后 2 年内发生变化。两种肥料来源的磷源与矿物磷肥的土壤质量指数在这两年没有显着差异。这些结果表明，土壤质量指数的变化不应在使用粪肥后的 2 年内发生变化。
