The Best Fertilizer to Make Your Lawn Green

Benefits

• Homeowners should have their soil tested every 3 to 5 years. A soil test can tell the nutrient balance of the soil. Homeowners can choose a fertilizer that supplies nutrients that the soil is deficient in.

Function

• Nitrogen is the most important element for lawns. Nitrogen in fertilizer promotes vigorous growth and green color. The amount of nitrogen a lawn needs varies among turf grass types.

Features

• Phosphorous is important to lawns in smaller amounts to stimulate root growth. Potassium is more important than phosphorous because it helps turf grasses to use nitrogen efficiently.

Significance

• Fertilizer is labeled with N-P-K numbers that indicate the ratio of nitrogen, phosphorous and potassium in the fertilizer. The best fertilizers for lawns have high N number, low P number and a moderately-high K number such as 22-3-14, 29-2-5 or 20-4-8.
