Manure spreader or other dry spreader is used to apply biochar. All material typically remains on the surface until incorporated by tillage which is recommended to avoid losses and maximize benefits from biochar. Minimal to no effective surface cover is provided by biochar and it can be transported by runoff and wind. Examples include manure based biochar and wood based biochar. crop_devnotes Changed mass to cover ratio set similar to compost and half life of about 10 years for decomposition coefficeint to be consistent with WEPP MJK 2-17-2021
