The Poison-Free Agricultural Promotion Center serves as a learning hub centered around the concept of sustainable sufficiency economy as per royal initiative. Nakhon Ratchasima province is a destination abundant with leisure activities, particularly in Wang Nam Khiao district, which is renowned for its natural beauty and refreshing atmosphere. When discussing agricultural tourism, there is no place more significant than visiting the organic vegetable garden at the Poison-Free Agricultural Promotion Center (Wang Nam Khiao), part of a initiative stemming from royal guidance. Founded in 1998, this project originated from a collective of farmers in Wang Nam Khiao who recognized the detrimental effects of chemical and toxic substances used in agriculture. These practices were directly impacting the environment and the health of local communities, particularly in the watershed areas. Consequently, they began transitioning to chemical-free agriculture and establishing a self-sustaining community economic model. They were subsequently honored to be integrated into the royal initiative, and today, their network spans the districts of Wang Nam Khiao, Sakhio, Kham Thale So, and Chok Chai in Nakhon Ratchasima province. Visiting agricultural spaces in such a pristine natural setting is a delightful form of relaxation that revitalizes the body and spirit. *Must-Visit Attractions* - Organic vegetable plots where you can observe the cultivation of pesticide-free vegetables as part of the project.
