Nutrients

Nitrogen 3% is the mineral element used in the greatest quantity by turf. Nitrogen is a component of many of the biochemical constituents of plants, including chlorophyll, amino acids, proteins, and enzymes. The addition of Nitrogen fertilizer can encourages ideal conditions for a dense attractive lawn.

Phosphorus 18% The proper level of phosphorus in your grass is essential for root and early plant development. Its primary role is in the storage and transfer of energy. Without sufficient P, normal growth and development cannot occur. Phosphorus fertilizer effects on turf are usually more subtle and, while not as readily visible, are still very important.

Potassium 18% is involved in carbohydrate formation, photosynthesis, enzyme activation, and the formation of proteins. Potassium fertlilizer plays a role in photosynthesis, and carbohydrate production is reduced when K is deficient. Potassium can enhance the plant’s endurance to stress if a deficiency is present.
