The effect of biochar on mycorrhizal fungi mediated nutrient uptake by coconut (Cocos nucifera L.) seedlings grown on a Sandy Regosol

Abstract

Highlights Application of biochar under wet moisture condition did not impact coconut seedling growth. Under dry moisture BC-Gly enhanced crop growth similar to wet treatments and plant P uptake. AMF growth was not impacted by biochar amendment aside from a stimulation in dry soil by BC-Gly. The N rich BC-Gly likely provides N to the plants via fungi stimulated biochar decomposition.
