Abstract:
A field-cum lab investigation on Influence of agroforestry systems on soil micro-nutrients was carried out. The main objective of the investigation was how agroforestry systems influence soil micro-nutrient status. The research was carried out on three agroforestry systems including Kadamb (Anthocephalus cadamba Miq.) based Agri silvicultural system, Simarouba (Simarouba glauca DC) based Agri silvicultural system, Litchi (Litchi chinensis Sonn.) based agri horticultural system, and one open system (without trees). DTPA extracting solution was used to analyse available Copper, Zinc, Iron and Manganese. According to the findings, all agroforestry systems have the ability to increase these micro-nutrient content in both surface (15 cm) as well as sub-surface (30 cm) soil. Simarauba had reported the highest micronutrient increasing capability compared to the other plantations and control plot.
