Technical Abstract: Biochar is under intensive evaluation by United States Department of Agriculture-Agricultural Research Service (USDA-ARS) scientists and cooperators for its many roles, such as an amendment to improve soil fertility, hydraulic properties, greenhouse gas reductions, and to sequester metals and plant nutrients in waste streams. In our laboratory, greenhouse and field evaluations, biochar amendments can effectively improve fertility of nutrient poor soils, increase hydraulic conductivities of hard setting soil layers, decrease nitrous oxide (N2O) emissions, and sorb dissolved copper and phosphorus in waste streams. Our research has shown that a biochar’s performance can be enhanced when characteristics of the biochar are specifically tailored or designed for the intended use. Currently, biochars are being designed by adding activating agents to manure and plant-based feedstocks or adjusting pyrolysis temperatures to create biochars capable of binding dissolved phosphorus in manure waste effluents and heavy metals in mine spoils. This presentation will highlight different biochar research projects and will discuss results produced by scientists from several USDA-ARS locations and collaborative projects with university and United States Environmental Protection Agency researchers.
