南达科他州的农民利用环隧道全年种植有机农产品,在USDA的支持下延长季节。 South Dakota farmers use hoop tunnels to grow organic produce year-round, extending seasons with USDA support.

地道农业使南达科他州的农民,如佩吉·马丁和塞达溪花园的布德曼克,能够将有机农产品种植到冬季,延长季节达四个月。 Tunnel farming is enabling South Dakota farmers like Peggy Martin and Bud Manke at Cedar Creek Gardens to grow organic produce well into winter, extending their season by up to four months. 农场利用塑料覆盖的套套结构,捕捉太阳能热量,维持西红柿、胡椒和甘蓝等作物的温暖和受控条件,允许早在3月种植,收获到12月中旬。 Using hoop structures covered in plastic that trap solar heat, the farm maintains warm, controlled conditions for crops such as tomatoes, peppers, and kale, allowing planting as early as March and harvesting through mid-December. 该系统支持在没有提高床位的情况下以土壤为基础的种植,并得到美国农业部财政援助的支持,帮助农场在恶劣天气下扩大当地粮食生产。 The system supports soil-based growing without raised beds and is supported by USDA financial assistance, helping farms expand local food production despite harsh weather.
