Abstract
Application of biochar (BC) to agricultural soils has raised global interest. BC could serve as a carrier for immobilization of beneficial microorganisms. Effect of straw-derived BC (50 t ha -1 ) with and without immobilized Trichoderma viride on the growth of maize in a sandy loam soil in Zemgale region (Latvia) was studied in a 128-day mini-field trial. Four treatment types were compared, i.e., without amendments [C], biochar [BC], biochar with T. viride [BCT], and T. viride [T]. The highest amount of Trichoderma spp. DNA was detected by qPCR in [BCT]. The obtained results demonstrated high heterogenity of soil samples. Addition of straw-derived BC with immobilized T. viride to sandy loam soil promoted survival of Trichoderma spp. and significantly (p < 0.05) increased maize growth. The highest germination index, i.e., 87.5%, after 14 days was observed in the [BCT] treatment. These results provide new methods for the optimization of cultivation conditions for maize in Northern latitudes.
