    Use of magnesium hydroxide and calcium compounds with and without a carrier medium to treat animal waste: to reduce air emissions (including ammonia volatilization) from, retain nutrients from, and manage phosphorous solubility of decaying animal litter, manure, and animal excretions and waste in CAFOs and animal enclousures; to reduce farm nutrient runoff; to extract and bind waste nutrients for fertilizer use; and to reduce air emission of waste-based fertilizers and animal bedding

    Abstract: A method for treating CAFO animal litter, manure and waste, reducing volatilization, retaining nitrogen and phosphorous, and reducing soluble phosphorus levels in litter, manure-based compost, and manure-based fertilizers. The method adds magnesium hydroxide (and calcium carbonate or calcium compounds) with or without a carrier medium to animal litter, compost, manure, and manure-based fertilizers as well as pet and zoo animal bedding material to maintain the litter pH at values inhibiting ammonia and hydrogen sulfide volatilization. Calcium compounds added to the litter and waste reduce soluble phosphorus runoff from fields receiving the resulting litter, fertilizer or lagoon water. Application of magnesium hydroxide and calcium compounds in CAFO waste, washwaters and lagoons precipitates a compound recoverable as fertilizer material. The method is effective in poultry, hog, and dairy CAFOs, animal care facilities, pet and zoo enclosures, pastures, agricultural fields, manure storage piles, animal waste treatment, manure-based fertilizer manufacture, and manure-based fertilizer products.

    Abstract translation: 一种处理CAFO动物垃圾，粪便和废物，减少挥发，保持氮磷的方法，降低垃圾，粪便堆肥和粪便肥料中的可溶性磷含量。 该方法向动物垃圾，堆肥，粪便和肥料为基础的肥料以及宠物和动物园动物床上用品中添加或不添加载体介质的氢氧化镁（和碳酸钙或钙化合物），以将枯枝落叶pH值保持在抑制氨 和硫化氢挥发。 添加到垃圾中的钙化合物和废物减少了从接收所产生的垃圾，肥料或泻湖水的田地的可溶性磷径流。 氢氧化钙和钙化合物在CAFO废水，洗涤水和泻湖中的应用，可以将化合物作为肥料回收。 该方法在家禽，猪肉，奶牛CAFO，动物护理设施，宠物动物园，牧场，农田，粪便储存桩，动物粪便处理，肥料肥料生产和肥料肥料产品中均有效。
