ABSTRACT Agrosilvopastoral systems have been used as sustainable production models that can promote soil organic carbon (SOC) storage. However, there are no simulation studies with the Century model to estimate the SOC accumulation capacity in the long term, analyzing the effects of management and climate change in integrated crop-livestock-forest (ICLF) systems. This study aimed to simulate soil C dynamics in two chronosequences of land-use composed of native vegetation (NV), degraded pasture (DPA) and ICLF system in the Cerrado of Minas […]

ABSTRACT New management practices applied to coffee crops may influence the soil’s capacity to tolerate vertical stresses. This paper aimed to evaluate the influence of two coffee crop management systems on the soil load-bearing capacity and critical soil water content to agricultural machinery traffic. This study was performed in the experimental area of the Federal Institute of the Southeast of Minas Gerais – Rio Pomba college, in Rio Pomba city, Minas Gerais, Brazil. Dystrophic Red-Yellow Oxisol (Latossolo Vermelho-Amarelo distrófico) (LVA7) […]

ABSTRACT Evidence of arbuscular mycorrhizal fungal colonization of mat litter in various ecosystems plus previous reports of external mycelium of those fungi and mycorrhizal roots in litter from coffee plants and shade trees on coffee plantations suggest that they have a relationship with closed direct nutrient cycling between organic matter and living roots. This relationship was first proposed more than 50 years ago. Mycorrhizal symbiosis in tropical crops is affected by agricultural management practices. This study aimed to assess the […]
Qualidade física de um Latossolo sob integração lavoura-pecuária-floresta no Cerrado brasileiro
01/abr/2014
A qualidade física do solo é um importante fator para a sustentabilidade dos sistemas agrícolas. O objetivo desta pesquisa foi avaliar as propriedades físicas do solo e o carbono orgânico em um Latossolo Vermelho distrófico, sob sistema de integração lavoura-pecuária-floresta. O experimento foi conduzido no Mato Grosso do Sul, Brasil. Os tratamentos consistiram de sete sistemas: integração lavoura-pecuária-floresta, com 357 árvores ha-1 e altura de pastejo de 30 cm (CLF357-30); integração lavoura-pecuária-floresta, com 357 árvores ha-1 e altura do pastejo […]
Comparação entre solos sob uso agroflorestal e em florestas remanescentes adjacentes, no norte de Rondônia
01/abr/2008
A importância e a eficácia dos sistemas agroflorestais na conservação dos solos tropicais necessitam de comprovações demonstrativas localizadas. Atributos físicos e químicos dos solos de sete parcelas com cinco anos e meio de uso agroflorestal, avaliados na camada de 0-0,2 m, foram comparados aos respectivos solos de florestas remanescentes adjacentes no norte do Estado de Rondônia. Não foram constatadas diferenças na composição granulométrica entre os solos na camada avaliada, sugerindo que os dois sistemas localizam-se sob o mesmo tipo de solo […]
