| Research Abstract |
Catch crop cultivation followed by flood irrigation simultaneously realized the reduction of nitrogen leaching and removal of salts accumulated in the topsoil of greenhouse horticulture. Polysaccharides in the corn biomass cultivated as a catch crop was easily hydrolyzed, and the L-lactate fermentation using sugars derived from the biomass was demonstrated. Around 80% of phosphorus in the corn biomass was recovered by soaking powdered biomass in distilled water and calcium addition to the extract. These results demonstrated that the proposed system was effective for the prevention of nitrate groundwater pollution and resource recovery.
