Effects of Biochar Feedstock and Co-Application with Organic Nitrogen Fertilizer on Soil Carbon Pools and Inorganic Nitrogen Availability
Biochar can increase soil carbon (C) and nutrient retention, but application of raw biochar may reduce inorganic nitrogen (N) availability and crop yields. As a result, biochar is sometimes co-applied with organic fertilizers, though the efficacy of this practice for preventing decreases in inorganic N remains unclear....
