**2.3 Ways for farmers to control weeds and soil loosening of soybean plants**

The way farmers control weeds in soybean cultivation generally uses traditional tools such as hoe. Farmers do not use herbicides in controlling weeds in soybean plantations because they can cause soybean death or leaf. In controlling weeds in soybean cultivation in paddy fields, farmers usually also loosen the soil. Weeds that have been honed are collected and then processed into organic fertilizer (fermentation). The fermented weeds after they become weathered are used for organic fertilizer on soybean plantations (**Figure 5**).
