Biochar: crop yield, greenhouse gasses and soil microarthropods

Carbon dioxide is increasing in the atmosphere; one of several ways to reduce the rate of increase is to sequester carbon in soil as biochar. Biochar is likely to have many effects on soils including changing populations of soil microarthropods, changing greenhouse gas production (especially nitrous oxide derived from fertilizer nitrogen); it may also change crop yields. The project will involve measuring all three on an RSPB farm in Cambridgeshire; the results may effect farming and conservation practice
