Most homeowners understand that applications of lime to the home lawn are necessary to maintain a high quality lawn. Few individuals, however, have a complete understanding of why lime is applied, how to determine if liming is needed and how to apply lime to the lawn. Also, most homeowners are not aware of the potential negatives of creating a pH too high by excessive application of lime.
Lime is applied to the lawn’s soil to increase its pH level. Soil pH, a measure of the soil's acidity or alkalinity, governs the availability of many soil nutrients and can directly influence the vigor and quality of the home lawn. When the pH is below 7, the soil is said to be acidic; when above 7, it is alkaline. For turfgrasses used in local lawns, a soil pH between 6 and 7 (slightly acidic) is ideal. PH levels that are too high (8+) will have the same effect as a pH level that is too low.
When the soil pH drops below 6, a number of nutrients necessary for proper growth become less available for use by the turfgrass plant. As nutrients become less available, the lawn's color, vigor and ability to resist or recover from heat, drought or traffic stress will be reduced. Applications of lime to raise the soil pH above 6 can increase the availability of these nutrients, making it easier to maintain the quality and vigor of your lawn.
New England soils tend to be naturally acidic. Factors that contribute to acidic soils are the breakdown of rock, the prevalence of pine trees and acid rain. A yearly maintenance application of lime is recommended. Testing the pH of your soil and application of an adjustment quantity of lime is ideal.
