NatureMate Sea Mate , 4oz. SeaMate is a balanced seaweed, N-P-K, trace mineral, carbon, and humic acid based water-soluble powder for use as a stand alone product, or as an ingredient in balanced fertility programs as a foliar nutrient spray or soil drench for plant growth and development. SeaMate has excellent flexibility due to its balanced formulation and neutral pH. SeaMate supplies levels of natural growth stimulants, soluble nitrogen, potassium and phosphorus in readily available forms. Combined with humic acid, the nitrogen, potassium, phosphorus, calcium, and iron can be rapidly absorbed and incorporated into the plant whether via soil or foliar application methods. SeaMate is compatible with almost all starter and foliar fertilizers for sustained nutrition. Simply, it makes the fertilizer with which it is applied work better.
