3 Basic Nutrient Elements For A Healthy Lawn and Garden

Nitrogen, Phosphorus and Potassium are three primary nutrients for a healthy lawn. Each one of these basic nutrient elements plays a major role in promoting a healthy turf.

Nitrogen

Nitrogen is very mobile in the soil, making it subject to leaching out of the soil faster than any other nutrient. As a result, nitrogen is the nutrient most likely to be deficient in lawns. Nitrogen promotes rapid growth, encourages a dense lawn and produces a dark green color. Too much nitrogen tends to reduce the lawn’s tolerance to extreme high temperatures and diseases. Just take care and simply do not apply fertilizer just for color.

Applying excessive nitrogen can burn the foliage during warm and dry conditions. Lawns deficient in nitrogen appear yellow-to-light green and grow slowly.

Phosphorus

Phosphorus is important for establishing and maintaining a healthy lawn. It is especially needed by young lawn grasses for the development of a strong root system. The amount of phosphorus can be determined by a soil test. If the soil test reads low, more phosphorus will be needed than if the soil test reads medium or high. Once the lawn is established, only a small amount should be required. Lawns deficient in phosphorus may have a red-purple color.

Potassium 

Potassium is used by the lawn almost like nitrogen. Potassium increases  resistance to diseases and improves the hardiness of lawns to temperature and moisture stresses.  If adequate amounts of potassium are applied when the lawn is established, only a small amount should be required for maintenance. If grass clippings are removed, nutrients will be depleted from the soil  faster than if clippings are mulched and  allowed to remain on the lawn. Lawns deficient in potassium may show a browning of the tips.
