Seaweed fertilizer enhances the water absorption, water retention, drought resistance and cold resistance of plants. It can be compounded with chemical fertilizers to form organic and inorganic compound fertilizers to enhance fertilizer efficiency, improve soil structure, increase soil permeability and water retention, and prevent soil deterioration. The contained mannitol can greatly increase the water absorption capacity and chlorophyll content of crops, and the leaf area increases by more than 10%. Abscisic acid regulates the closure of leaf stomata, reduces the water loss of crops, and can reduce the amount of fertilizer and water by about one third.
