When a soil test report recommends lime, the application rate given is either T , for tons per acre, or M , for pounds per thousand square feet. Application of the suggested rate should increase the pH to a level suitable for the crop. Unlike fertilizer, lime can be applied at any time of year. Changing the soil pH requires a chemical reaction that does not occur immediately. Therefore, lime should be applied as soon as possible after the need is realized.
Lime is available in pulverized and pelletized forms.
Both types use the same lime material, only the form is different. Both types work equally well with no significant differences in reaction time or results. The pulverized form is less expensive, but the pelletized form is easier to apply. There are two types of lime available, calcitic and dolomitic. Calcitic lime is composed of calcium carbonate and contains little or no magnesium.
