農場野菜と菌類の一体化栽培計画：デュアルエンジン駆動、高効率な生態農業の循環構築

Henvic's integrated farm solution combines vegetable and mushroom cultivation in one closed-loop system. Vegetable straw and vine waste become mushroom substrate, while spent mushroom residue turns into organic fertilizer for vegetables, cutting chemical use and cost. The model boosts land value by 30% or more, reaches a 95% premium-product rate, and builds a replicable eco-agriculture model.
