牛粪的土地传播是有效的，在处理废物和利用植物养分的粪便。本研究的目的是确定肥料的残留效应后，3年的应用率为0，22.5，45，90，180和270公吨/公顷，分别纳入2土壤。在这些3年中的每一年中，用珍珠粟[Pennisetum americanum（L.）K. Schum“Gahi 1”]和黑麦（Secale cereale L. ''雷恩''s Abruzzi''）.在实验的剩余阶段，用黑麦和玉米（Zea mays L.）#35757;，4年。从高施用率的奶牛粪便的残留物增加了玉米的产量Dothan壤土砂（Plinthic Paleudults）和Lucedale桑迪壤土（Rhodic Paleudults）4年后的肥料。在多森土壤上，高比例的粪肥对黑麦生长产生不利影响。大多数年份，残留物增加了两种作物在两种土壤上的氮吸收。高比例的粪肥增加pH值的深度超过100厘米的多森土壤。K在100 cm以下土层中积累。磷素在60-75 cm土层中逐渐增加。Mg也向下层土壤迁移，Ca在表层以下30 cm处几乎没有迁移。对pH值，K，P和Mg的运动的影响是小得多的Lucedale土壤比粗质地的Dothan土壤。高施肥量增加了土壤pH值和土壤K、Mg、P含量，提高了土壤阳离子交换量。这些因素有助于提高肥料处理地块的作物产量。对牛粪的反应可以在停止高比例施用牛粪后测量4年或更长时间。
Land spreading of dairy manure is effective both in disposing of waste and in utilizing plant nutrients in the manure. This study was conducted to determine the residual effect of manure after 3 annual application at rates of 0, 22.5, 45, 90, 180 and 270 metric tons/ha were each incorporated into 2 soils. Plots were double-cropped each of those 3 yr with pearl millet [Pennisetum americanum (L.) K. Schum ''Gahi 1''] and rye (Secale cereale L. ''Wren''s Abruzzi''). During the residual phase of the experiment, plots were double-cropped with rye and corn (Zea mays L. ''Funks 5757'') for a period of 4 yr. Residue from high application rates of dairy cattle manure increased yields of corn on both Dothan loamy sand (Plinthic Paleudults) and Lucedale sandy loam (Rhodic Paleudults) for 4 yr after the manure was applied. On the Dothan soil high rates of manure adversely affected rye growth. Most years, the residue increased N uptake in both crops on both soils. The high rates of manure increased pH to a depth of over 100 cm on the Dothan soil. K accumulated in the subsoil to the 100 cm depth. P was increased to the 60-75 cm soil depth. Mg also moved into the subsoil, but there was little movement of Ca below the surface 30 cm. The effect on pH, K, P and Mg movement was much smaller on the Lucedale soil than on the coarser-textured Dothan soil. The high rates of manure increased soil pH and soil contents of K, Mg and P and increased the cation exchange capacity of soils. These factors contribute toward higher crop yields on manure-treated plots. Response to dairy manure may be measured for 4 yr or more after high rates of manure applications have been stopped.
