Soil Improvement from Application of Biochar
Question: What is the Evidence That Biochar Benefits Soils in Actual Field Conditions?
Field trials using biochar have been conducted in the tropics over the past several years. All showed neutral or positive results on yields when biochar was applied to field soils and nutrients were managed appropriately. Large scale field trials have recently begun on highly fertile Iowa Mollisols by the US Department of Agriculture’s Agricultural Research Service (USDA-ARS).
