This report produces Leaching Index Values (1, 2 and 3) suitable for use as described in Part

539.58 - National Ranking Factor N2, Subfactor B in the CRP Manual. The index information

presented in the report is a weighted average of the component indexes by the map unit

component percent composition.

The values 1, 2 and 3 are derived by using the same algorithms included in the SOIL PESTICIDE

INTERACTION SCREENING PROCEDURE II, Goss and Wauchope, November, 1990. These algorithms

produce the leaching values 1, 2, 3 and 4 but this report reverses the order of meaning and

combines values 3 and 4. Thus, this report, as required by CRP rules correctly reports 1 as

low, 2 as medium, and 3 as high. These values are ready for use in determining signup scores

for National ranking subfactor N2 without further code conversion.
