Okaloosa County: Soil Ratings for Selecting Pesticides 1<br />
G.W. Hurt and T.A. Obreza 2<br />
RATINGS FOR OKALOOSA COUNTY<br />
SOILS FOR PESTICIDE SELECTION<br />
Resource soil scientists with the U. S. Natural Resources<br />
Conservation Service have rated the soils that are delineated<br />
by map units in the Okaloosa County Soil Survey Report 2<br />
for their potential for leaching and run<strong>of</strong>f <strong>of</strong> pesticides. The<br />
rating criteria are given in a companion publication entitled<br />
“Soil Ratings for Selecting Pesticides for Water Quality<br />
Goals.” These soil ratings have been developed to help<br />
pesticide users determine the potential for pesticides to be<br />
lost to groundwater or surface water bodies.<br />
As explained in Circular 959 1 , factors that determine<br />
pesticide leaching ratings in soil are permeability and the<br />
occurrence <strong>of</strong> mucky layers in the upper 80 inches <strong>of</strong> the<br />
soil. Soils rated High have a high potential for pesticides to<br />
leach to groundwater, soils rated Medium have a medium<br />
potential for pesticides to leach to groundwater, and soils<br />
rated Low have a low potential for pesticides to leach to<br />
groundwater. Factors that determine pesticide run<strong>of</strong>f<br />
ratings from soils are hydrologic group, permeability, and<br />
slope. Soils rated High have a high potential for pesticide<br />
run<strong>of</strong>f, soils rated Medium have a medium potential for<br />
pesticide run<strong>of</strong>f, and soils rated Low have a low potential<br />
for pesticide run<strong>of</strong>f.<br />
NOTE: The user may discover that one or more map unit<br />
names in Table 1 have been updated from names given in<br />
the legend <strong>of</strong> the soil survey report 2 . For example, a soil<br />
map unit may be listed in the survey report with a single<br />
soil series name, whereas the same soil map unit is shown<br />
as comprising two or more soil series in Table 1 (sequence<br />
numbers 1, 2, 3, ..) Where this occurs, the user should use<br />
the multi-named map unit given here, and make pesticide<br />
selections based on the most limiting condition to be found<br />
on the land in question. If necessary, the local Natural<br />
Resources Conservation Service <strong>of</strong>fice should be contacted<br />
to perform an on-site evaluation <strong>of</strong> the land in question.<br />
