Plant geneticists once doubted whether yams could be grown in clay soil like the lower central Chao Phraya basin. By naturally tilling and fertilising the soil, winged bean has delivered massive yields and slashed fertiliser costs. From these high-yield results to FoodInnovate’s organic seed donation in Lat Bua Luang Agricultural Office, we are proving that restoring soil health is the key to a sustainable, low-cost agricultural future.
