Abstract
Biochar is a solid “charred” organic residue produced by heating plant material in the absence of oxygen (pyrolysis). Biochar tends to have high aromaticity and reduced oxygen to carbon and hydrogen to carbon ratios. As such, it is more resistant to microbial decomposition than the original plant residues or ‘feedstocks’ (e.g., crop residue, straw, wood, shells, etc.). Applying biochar to agricultural soils has shown potential to increase soil carbon storage, reduce GHG emissions, enhance soil health, and improve yields. However, much remains uncertain about the practical application and impacts of biochar in working agricultural systems. This trial aims to assess the impact of biochar incorporated just prior to the application of urea fertilizer and dairy liquid manure on soil nutrient concentration, soil health indicators, corn silage yield, and quality.
