Native and exotic tree leaves litter contributions to soil organic matter formation in revegetation strategies
16/jun/2025
ABSTRACT The use of native and exotic species in the reforestation of degraded areas has been considered an important strategy to improve soil quality. However, there is still scarce information about which species are more efficient for soil organic matter (SOM) formation. This study aimed to evaluate the decomposition of leguminous and non-leguminous tree litter, its impact on light organic matter (LOM), particulate organic matter (POM), and mineral-associated organic matter (MAOM) dynamics, and consequently, SOM formation efficiency. Leaf litter from […]
Clonal teak litter in tropical soil: decomposition, nutrient cycling, and biochemical composition
26/nov/2020
ABSTRACT: Litter decomposition dynamics and nutrient release are also dependent on their biochemical composition, and such information is important for adequate nutritional management but is still incipient for plants like teak. This study aimed to evaluate the decomposition dynamics, nutrient release, and biochemical composition of clonal teak litter. The study was conducted in areas of clonal teak stands, in São José do Rio Claro, Mato Grosso, Brazil. Litter collectors were arranged in the area to collect material along the entire […]
Decomposição e liberação de nutrientes de resíduos culturais de plantas de cobertura em argissolo vermelho-amarelo na região noroeste Fluminense (RJ)
01/dez/2007
A decomposição pode assumir importante papel no manejo da fertilidade do solo, possibilitando a elaboração de técnicas de cultivo que melhorem a utilização de nutrientes contidos nos resíduos vegetais. O objetivo deste trabalho foi estimar as taxas de decomposição e liberação de C, N, P, K, Ca e Mg de resíduos culturais provenientes de plantas de coberturas na cultura do maracujá. As espécies avaliadas foram feijão-de-porco (Canavalia ensiformis), amendoim forrageiro acesso CIAT 1734 (Arachis pintoi), siratro (Macroptilium atropurpureum), cudzu tropical (Pueraria […]
