Making dry fertilizer involves mixing animal manure, rice husks, rice husk ash, and fine bran until they are well blended. A concentrated microbial culture is added, and the mixture is mixed until it forms a lump. It is often used during soil preparation, where the soil is mixed with the soil in the plot. The soil is then covered with straw, leaves, or branches. The soil should be left to ferment for seven days before planting (in the case of rice fields, field crops, and vegetables).
