Summary

This 2024 field study examines litter deposition and decomposition processes in a tropical grass–legume silvopastoral system integrating woody, legume and herbaceous forage components. The work quantifies how each system component contributes to organic matter cycling and nutrient release pathways, contributing to understanding of soil health maintenance in agroforestry systems that combine livestock production with tree cover. The findings are likely relevant to soil carbon sequestration and nutrient cycling efficiency in integrated farming systems operating under tropical or subtropical conditions.

UK applicability

Whilst the climatic and edaphic context is tropical, the mechanistic understanding of litter-mediated nutrient cycling in mixed-component agroforestry may inform management of temperate silvopastoral systems with tree–pasture integration. Direct applicability to UK farming remains limited by differences in temperature, growing season length and plant species composition.

Key measures

Litter fall (mass and nutrient content), decomposition rates, nutrient release kinetics, organic matter accumulation by component type (trees, legumes, grasses)

Outcomes reported

The study measured litter deposition rates, litter decomposition dynamics, and nutrient release patterns across woody, legume and grass components in an integrated silvopastoral system. The work quantified how organic matter inputs and cycling pathways vary by system component and contribute to soil nutrient availability.
