“…In the studied profile (0-20 cm), the IMC ranged from 51.57 (TCP 10-20 cm) to 99.96 (TC 5-10 cm) within the use systems. As cited by Blair et al (1995) and confirmed by several researchers, IMC values below 100 are typically found in studies where land use and management practices are degrading and indicative of a negative impact on the levels of organic matter, affecting soil quality as a result (COSTA et al, 2004), as was observed in all systems, with all layers having values below 100. Therefore, the most negatively affecting system at the 0-5 cm layer was the TC system, followed by the T8 system at the 5-10 cm layer, and the TCP system at the 10-20 cm depth layer.…”

“…Ressalta-se que a baixa profundidade média do uso D pode ter contribuído para a saturação por água das camadas superficiais desses solos, em especial na época das chuvas, normalmente de alta intensidade, o que tornou o ambiente menos oxidativo, permitindo maior acúmulo de COT nos solos. Costa et al (2004) registraram, em experimento de longa duração em Guarapuava, Paraná, em um Latossolo Bruno submetido a cultivo convencional, um teor de COT de 3,4 dag kg -1 , média das camadas de 0-5 e 5-10 cm. O clima ameno da Região Sul provavelmente proporcionou um ambiente favorável à manutenção do COT do solo.…”

“…Esse fato já podia ser esperado, em razão do baixo teor de matéria seca e carbono orgânico que os dejetos líquidos de suínos apresentam. Em média, os dejetos de suínos da região oeste de Santa Catarina apresentam 3 % de matéria seca (Scherer et al, 1996) (Costa et al, 2004).…”
