Abstract: A field-cum lab study conducted on ‘soil micronutrients status of different agroforestry systems in north Bihar’. The work took to check out how agroforestry systems act on micronutrient status of soil. The investigation conducted on three agroforestry systems which includes Kadamb (Anthocephalus cadamba Miq.) based agrisilvicultural system, Simarouba (Simarouba glauca DC) based agrisilvicultural system , Litchi (Litchi chinensis Sonn.) based agri horticultural system and one open (without trees). Available micronutrient cations (Copper, Zinc, Iron, Manganese) were analyzed by using DTPA extracting solution. Study revealed that all agroforestry systems has ability to increase micronutrient contents in both (15 cm and 30 cm) depths of soil. It was also noticeable that among the three plantation Simarauba recorded highest micronutrient reviving capability over control plot. Surface soil accounted higher presence of all micronutrients over lower soil in all plots.
