Revegetation: Lime Application

In order to incorporate lime amendments for soil acidity neutralization, application is accomplished prior to soil tillage. Not all soils will be acidic therefore, lime addition will only be necessary on a site by site basis. In the event that lime amendments are necessary, surficial application may be accomplished by a variety of equipment. Independent of the choice of application equipment, amendments should be spread uniformly on the soil surface. Measurement of the amendment rate is required for calibration of the spreading and for documentation of the rate of application for post construction reporting. Measurement of amendment application rates can be performed by placing a tarp of known area on the ground prior to amendment application followed by weighing of the material captured on the tarp.

Lime spreading is particularly sensitive to weather conditions. Good judgement should be employed in selection of weather suitable to lime addition. Limiting conditions include windy weather which causes loss of lime to the atmosphere as dust, and wet soil conditions which may cause "clumping" of the lime and poor incorporation efficiency. Staging of lime stockpiles nearby areas to be amended is encouraged to expedite loading of spreaders.
