Cheongju City is supporting snail seed for producing high-quality eco-friendly rice. The city is supplying 130 tons of snails to 1,831 rice farming households (cultivation area of 1,892 hectares) with a total project budget of 860 million won. The snail farming method utilizes the weed-eating habit of snails to control weeds in rice paddies. By introducing snails to the paddy 7 days after transplanting, farmers can prevent damage to young rice plants and achieve weeding effects. Additionally, eco-friendly rice cultivation using snails can reduce labor for weeding and cut production costs by approximately 50% compared to herbicide use. However, snails have strong reproductive capabilities and a rapid spread rate.
