liming

liming

the addition of calcium compounds to the soil, producing three main effects:
  1. the provision of the major element calcium,
  2. the neutralizing of acid soils,
  3. the promotion of flocculation (clumping) of clay particles into larger crumbs, so as to encourage aeration and drainage.

However, residual acidity represents the greatest contributor of acidity to soil (1000 to 10,000 times as much as the other two), so liming recommendations are based on neutralizing residual soil acidity.

A secondary objective is to determine the influence of liming treatments, following a controlled burning program, on the soil's structure and its physical and chemical attributes.

Ultimately the model may be integrated into a decision support system (DSS) for the site-specific management of soil acidity by variable-rate liming. Anderson and Humburg (1997) provided a review and description of variable-rate application equipment for site-specific management.

Rather than liming the acidified waters themselves, this treatment limes the land draining into them.
