Impact of Agroforestry on soil fertility and soil carbon: A Review

Abstract

Agroforestry combines woody perennials with arable crops, grasses and / or livestock, on the same piece of land, promoting more efficient resource utilization when compared to mono-cropping through structural and functional diversification. This integration offers various soil-related ecological services, such as enhancing fertility and improving soil's physical, biological, and chemical properties, while also providing food, wood, and fodder. Agroforestry systems have gained recognition for their potential to enhance soil health and productivity while promoting sustainable land management. Volume of innovative research has led agroforestry to address complex issues related to food security and climate change for wellbeing of the people. This review is an attempt to understand the role of agroforestry in improving soil quality, microclimates and productivity, particularly in degraded areas, when management practices are carefully considered. It also lists some of the researchable gaps and issues for future.
