Lafayette County: Soil Ratings for Selecting Pesticides1

G.W. Hurt and T.A. Obreza2

RATINGS FOR LAFAYETTE COUNTY SOILS FOR PESTICIDE SELECTION

Resource soil scientists with the U. S. Natural Resources Conservation Service (formerly the U. S. Soil Conservation Service) have rated the soils that are delineated by map units in the Lafayette County Soil Survey Report2 for their potential for pesticide leaching and runoff. The rating criteria are in a companion publication entitled "Soil Ratings for Selecting Pesticides for Water Quality Goals." These soil ratings have been developed to help pesticide users determine the potential for pesticides to be lost to groundwater or surface-water bodies.

As explained in Circular 9591, factors that determine pesticide leaching ratings in soil are permeability and the occurrence of mucky layers in the upper 80 inches of the soil. Soils rated High have a high potential for pesticides to leach to groundwater, soils rated Medium have a medium potential for pesticides to leach to groundwater, and soils rated Low have a low potential for pesticides to leach to groundwater. Factors that determine pesticide runoff ratings from soils are hydrologic group, permeability, and slope. Soils rated High have a high potential for pesticide runoff, soils rated Medium have a medium potential for pesticide runoff, and soils rated Low have a low potential for pesticide runoff.

NOTE: The user may discover that one or more map unit names in Table 1 have been updated from names given in the legend of the soil survey report2. For example, a soil map unit may be listed in the survey report with a single soil series name, whereas the same soil map unit is shown as comprising two or more soil series in Table 1 (sequence numbers 1, 2, 3, ...) Where differing leach and runoff ratings occur between soil series within the same map unit, the user should use the multi-named map unit given here, and make pesticide selections based on the most limiting condition found on the land in question. If necessary, the user should contact the local Natural Resources Conservation Service office for an on-site evaluation.

SEQ NUM = Sequence Number, indicating a particular soil series name among one or more names constituting a map unit name.
MUSYM = Map Unit Symbol from the soil map and legend in the Soil Survey of Lafayette County, Florida. Note: If a MUSYM appears more than once in this list, it signifies that two or more soil series are co-dominant in that map unit, and each is rated separately here.
SOIL SERIES NAME = Name of soil or other landscape component (urban land, made land, borrow pits, spoil banks, etc.).
SOIL LEACH = The rating of the soil for leaching of pesticides through the soil profile.
SOIL RUNOFF = The rating of the soil for runoff of pesticides from the soil surface.

NOTE: See "Soil Ratings for Selecting Pesticides for Water Quality Goals" (IFAS Extension Circular 959) for explanations of the criteria used to develop soil ratings presented in the two right-hand columns of this list.
