Abstract
Litter dynamics is a primary mechanism of nutrient recharge in natural, as well as man-made agro- ecosystems through the process of biogeochemical cycling of the elements in terrestrial ecosystems. The deposition of senescent plant material alters the availability of essential soil nutrients, which in turn supports plant growth dynamics and enhances overall forest productivity. Litter dynamics (litter production and decomposition) has significant role in the sustainable management of tropical forest, and as these ecosystems are highly productive, hotspots of biodiversity, vital for the global carbon cycle, support livelihood of millions of people, bridges the gap between demand and supply of wood and other forest produces, and strongly depends on internal nutrient cycling which often highlighted as ecosystem of specific research interest. Therefore, the present study attempts to critically review on litter dynamics of tropical forests and agroforestry systems to understand their role in nutrient cycling, soil health, and ecosystem sustainability.
