Lawn Fertilizer and Lawn Nutrients: The Basics


Applying lawn fertilizer is an essential maintenance practice for achieving a healthy lawn. Regular application of turf fertilizer provides essential lawn nutrients that might not be present in your yard, helping to improve your lawn’s appearance and health.

Healthy lawns have better color, density, growth and tolerance to stress factors. Healthy lawns also:

  • Resist stresses like drought, insect and disease damage
  • Have fewer weeds and insects
  • Require fewer control applications over time
  • Reduce run-off and erosion
  • Provide cooling effect in the immediate surroundings

There are many factors that will determine which type of lawn fertilizer is best for your lawn. These include seasonal growth pattern of the turfgrass in your lawn, local weather and climate, and also the lawn nutrients that your turfgrass demands. Only a trained lawn care specialist can help determine which lawn nutrients are necessary for your turfgrass, as well as what levels are best to produce a lush, thick lawn.

Primary and Micro Nutrients-

Dry vs. Liquid Lawn Fertilizer -

There is very little difference between dry and liquid lawn fertilizer when it comes to lawn response and turfgrass nutrition. The common misconception is that liquid fertilizers are quick-release and cause rapid growth, while granular fertilizers feed the roots and last longer. Turfgrass plants eventually require all nutrients to be in soluble form before they can be used so the carrier ultimately makes little difference to the plant.

Cool Season Turfgrass Nutrition


Cool season grasses grow well during the mild periods of the year, so lawn fertilizer practices must match the growth and development periods of the turf. For example, in order to maintain quality turf, a greater percentage of slow-release nitrogen is often used during warmer periods of the year when cool season turfgrass growth slows. Conversely, a lower percentage is used during cool periods of the year when turf is actively growing.


Warm Season Turfgrass Nutrition


Warm season grasses grow well during the warm periods of the year, so lawn fertilizer practices must match the growth and development periods of the turf. There is great diversity in growing conditions for warm season turf. In most areas where warm season turf is adapted, there is a period of dormancy and a period of active growth. In these cases, nitrogen is applied only during periods of active growth. However, in some parts of the southern United States, warm season grass grows year-round and nitrogen applications can be made all year.
