Intensive pig farming is an important economic activity and generates a large amount of liquid pig manure as a by-product, which is considered a promising resource for the fertilization of tropical soils, characterized as low natural fertility. In an agricultural area under no tillage soybean-corn cropping system, located in southwest of Brazil, an experiment was carried out with different forms of fertilization; that is, organic fertilization with pig manure (17 years) at different rates of application and with mineral fertilization. Regarding the pig manure application rate, with yearly carbon load of 50 m³ ha⁻¹ tended to promote the mineralization of organic matter, with formation of humic substances and to improve the size of aggregates. The use of LPM promoted little soil carbon addition varying of 0.05-3.41 kg ha⁻¹ with 17 years of LPM application and the continuous application of pig tended to be advantageous for the tropical soil, providing a positive carbon balance, which favored the soil and the environment through the rational waste disposal.

集约化养猪是一项重要的经济活动，会产生大量的液态猪粪副产品，被认为是天然土壤肥力低下的热带土壤施肥的有前途的资源。在巴西西南部一个没有耕种大豆玉米种植系统的农业地区，进行了不同施肥形式的试验；也就是说，用猪粪（17年）以不同的施用量和矿物肥料进行有机施肥。关于猪粪的施用量，年碳负荷为50 m ³ ha ^-1趋于促进有机物质的矿化，形成腐殖质并改善集料的大小。LPM的施用使LPM施用了17年，几乎没有增加0.05-3.41 kg ha ^-1的土壤碳添加量，连续施用猪对热带土壤有利，提供了积极的碳平衡，有利于土壤和土壤。通过合理的废物处理环境。
