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.
