What You Need to Know About Turf Grass Nutrition
Turf grass nutrition consists of over 16 different elements that are required for good growth, development and health. Three of these components are carbon water and oxygen that can all be taken from air and water. The other thirteen are available in the soil or can be applied as a supplement if needed. These elements can be broken down into major nutrients, trace nutrients elements and micronutrients.
Major nutrients would include nitrogen, phosphorous and potassium. Trace nutrients for turf would be calcium, magnesium and sulphur. The micronutrients would consist of zinc, molybdenum, manganese iron, copper, boron and chloride. All sixteen nutrients need to be available for healthy turf grass in various amounts. Soil test should be done before applying products.
Turf Grass Nutrition Major Elements are:
Nitrogen is one of the most important nutrients needed by turf grass and one that is needed in the greatest amounts. Nitrogen is responsible for the growth and green color in turf. Nitrogen can improve the color and growth of a lawn quickly but if misused can harm the turf and the environment. Nitrogen is one of the main ingredients in fertilizer and also one of the most expensive.
Phosphorous is involved with holding and transferring energy required by turf grass plants for metabolic processes. Phosphorus deficiencies are rarely observed in established turf, unless the phosphorus in the soil is extremely low or an unfavourable soil pH exists. Where a deficiency does occur, turf plants may suffer from reduced growth, dark or reddish leaf color, or narrow leaf blades.
Potassium plays a vital role inhealthy turf grass growth and development and is second to nitrogen in the amounts required for turf growth. Potassium is involved in cellular metabolism, environmental stress resistance, disease incidence, internal water management, and wears tolerance. The principal factors affecting the potassium requirement for turf are clipping removal, irrigation, and soil texture. If the clippings are removed, larger and more frequent applications of potassium are generally required to maintain satisfactory growth. The specific requirement is usually about half the rate of nitrogen
