A high potassium analysis NPK solution incorporating nitrification inhibitors and humic acid, optimal for intensively managed turfgrass

THE ROLE OF NITROGEN

Maintenance, but not excessive, rates of nitrogen are required for optimum health of intensively managed turfgrass. Nitrogen is the essential building block of plant structure and is vital to plant growth but can be a limiting factor in uptake of other nutrients. Highly mobile in the plant, it is translocated and utilised in the growing tips. Nitrogen is often leached from the soil therefore regular application in low doses will ensure efficient uptake without excessive losses.

THE ROLE OF PHOSPHORUS

Phosphorus acts as a structural component of nucleic acids and phospholipids w hich form plant membranes. It is also important in root growth, cell division, photosynthesis, sugar and starch formation, energy transfer and movement of carbohydrates. Without phosphorus, turfgrass growth and health is limited due to low energy production

THE ROLE OF POTASSIUM

Highly mobile in the plant, potassium regulates the turgidity of cells and is therefore important in stomata control and turfgrass strength. Potassium also maintains cell division, formation of proteins, carbohydrates and fats. Deficiencies of potassium generally result in a weakened turfgrass plant that is susceptible in periods of high stress.

THE ROLE OF HUMIC ACIDS

Humic acid, the active constituent of humus, plays an important role in nutrient availability and cation exchange. Microbial activity, water-holding capacity and soil structure all improve with humic acid application. Its inclusion within the formulation greatly enhances the uptake of the applied nutrients.
