Why is lime added to soil




















Calculating the effective neutralizing value ENV of a liming material accounts for the two contributing effects purity and fineness that determine expected soil pH increase after application.

For all calculations, use decimals rather than percentage values. Example : A liming material with a CCE of 80 percent 0. The actual rate of a liming material to be applied can then be calculated from the soil-test recommendation, assuming that standard agricultural lime has an effective neutralizing value of 90 percent 0.

Compared to standard ag lime: 0. If this material had been evaluated using just CCE, the lime equivalence would have been calculated as: 0. Within one to three years, lime moves little in the soil and neutralizes acidity only in the zone where it is applied.

To be most effective, lime must be uniformly spread and thoroughly incorporated. The poorest, but most common, method of application to field crops is by spinner spreader. Double spinner spreaders apply more uniformly than single spinner spreaders; however, both types normally apply more lime immediately behind the spreader than to its sides. In practice, rates are adjusted after checking the spreader pattern and making appropriate correction. If the application is not correct, strips of underlimed and overlimed soil could result, possibly reducing crop yields.

Lime can be applied more evenly using full-width box or boom spreaders. Full-width spreaders allow lime to fall to the ground by gravity. The rate is determined by the size of the openings in the box and by ground speed. Boom spreaders use drag chains, augers, or air pressure to move lime out the booms and drop it on the ground.

If adjusted properly, both types of spreaders are vastly superior to the spinner type. The main limitations to their use are the high initial cost and more complex operation. Most commercial farmers likely will continue using spinner spreaders, but every attempt should be made to spread lime evenly.

Lime can be applied to yards and gardens by hand or with small manual or garden tractor spreaders. The best way to achieve uniform application at the appropriate rate is to measure the amount needed to cover the entire area, apply half while traveling with swaths oriented in one direction, and apply the other half with swaths oriented perpendicularly. The most commonly used lime incorporation tool for field crops is the disk.

Its main limitation is that it incorporates lime only about half as deeply as the disk blades penetrate. Even with repeated passes, it will not incorporate lime well. Offset disks that throw the soil perform better. The best incorporation implement is a heavy-duty rotary tiller that mixes the soil throughout the root zone.

Bottom plowing immediately after spreading lime will likely bury the lime too deeply. If plowing, the best approach is to apply half the lime, then disk and bottom-plow, then apply the other half, and disk again. However, this process is costly and is not generally used. Certain other tillage practices, such as bedding or middle busting, will help with lime incorporation in the long run.

Chisel plowing is very ineffective for lime incorporation. Although lime is applied on the surface to established pastures and lawns, it should be incorporated at establishment to reduce soil acidity.

Lime can be incorporated into lawns and gardens with rototillers, spades, or rakes to a depth of 4 to 8 inches. For established lawns, lime can either be left on the surface or applied prior to aeration. Long-term no-till cultivation is becoming increasingly popular in North Carolina and obviously limits the ability to incorporate lime into the soil profile.

A survey of no-till fields in North Carolina detected slightly higher soil pH at the surface with notill management, a reflection of surface lime application. Nevertheless, producer experience suggests no inherent problem maintaining optimum soil pH with surface liming in long-term continuous no-till. It is critical, however, to correct soil acidity and other fertility problems, particularly low phosphorus levels, by thorough incorporation of lime and fertilizer prior to the adoption of no-till management.

Research in Pennsylvania has documented that low soil pH problems can persist for several years following application of lime to the surface of no-till fields. Maintenance of proper soil pH can increase your crop income and improve your lawn and garden performance. However, varying rates of lime are recommended, depending on the best pH for the particular soil class and crop combination. Crozier, C. Osmond, D. Crozier, and D. Tucker, M. Messick, and C.

In many parts of the country, adding lime to your lawn is as essential as mowing it. Without lime, lawn grasses may be unable to benefit from the nutrients in your soil, including those you add through fertilizers.

By understanding how lime helps lawns and why you may need lime, you can help your lawn reach its full potential. The following questions and answers can help guide you through that process, so you can lime your lawn confidently: What is lime?

Why apply lime? How do I know when my lawn needs lime? Why is soil testing important? Why does soil pH keep changing? It takes special skills to care for the soil of plants and trees. Please keep in mind that you should not attempt lime application to soil on your own.
