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.
