Intense soil preparation and disturbance in crops, over time, reduces the quantity quality of organic matter. Given this context, work aimed to determine carbon stocks labile fractions under agroforestry system (AFS) toposequences an altitude marsh, Taquaritinga do Norte, Pernambuco, Brazil. The study was carried out at Yaguara farm, areas studied were native forest with 4.57 ha coffee plantation shade 25.59 ha. Soil samples collected four trenches measuring 1.5 x 0.60 m, a distance 50...
MOS (soil organic matter) is a natural carbon reservoir, and divided into different stages of decomposition according to its solubility structural complexity. In view this context, work aimed quantify the content in humic fractions soil matter under an agroforestry system three toposequences swamp altitude Pernambuco, Brazil. The study was carried out on Yaguara farm, studied areas were native forest system. Soil samples collected trenches 1.5 x m, at depths 0-20, 20-40 40-60 cm, with four...
The present work aimed to quantify the concentrations and biomass stock of fine andthick roots, in three areas municipality Capitão Poço-PA, Brazil. used were degraded area, recovery area native forest. For soil sampling, 24 trenches opened, measuring 70 x 100 cm. In these trenches, samples taken at depths 0-10, 10-20, 20-30, 30-40, 40-50, 50-60, 60-80 80-100 cm sieving was carried out.All roots other underground plant structures that remained sieve collected by manual collection. separated...
O Brasil é líder mundial na produção e exportação de café, cultivados em diferentes sistemas manejo. Sabe-se pouco sobre os efeitos ambientais desses sistemas, assim, o objetivo desse estudo foi utilizar parâmetros físicos, químicos biológicos do solo como indicadores nas mudanças no sistema agroflorestal Taquaritinga Norte, Pernambuco, Brasil. As amostras foram coletadas três posições relevo: terço superior - TS, médio TM inferior TI da encosta. Foram avaliados atributos físicos...
Through sustainable agriculture it is possible to explore the coffee culture in consortium with native forests more rugged reliefs, as a permanent crop addition climatic conditions offered by swamps that favor its development. Given above, present work proposes, based on acidity results, quantify need for correctives soil obtain better nutritional use agroforestry cultivation of organic shade favorable results increase productivity and, consequently, farmer's profit. The research was carried...
