Determination Of The Efficacy Of Fertilization Practices On Bob Kidd Lake, Richard L. Meyer, Jeanette K. Shipley-Phillips
Technical Reports
Fertilization strategies have been used as a standard practice on Bob Kidd and other lakes and reservoirs to enhance the availability of phytoplankton and zooplankton as food sources for developing fish. The nominal practice is to use a fixed application rate and a constant ratio of nitrogen and phosphorus fertilizer per acre of lake surface. The application technique varies as does the timing. Application techniques vary from spillage and bulk deposition of fertilizer at selected sites to broadcasting of pellets or a pre-mixed slurry via boat and/or airplane. Timing is usually in the spring under appropriate weather conditions.

Woodruff County Groundwater Vulnerability, H. D. Scott
Technical Reports
There is much unknown about the extent of pesticide contamination of groundwater in Arkansas. In recent years, several research studies have been conducted where wells for irrigation and domestic uses have been sampled and analyzed for pesticides (Lavy, 1988; USGS,1993; Nichols, et al., 1993). For state and federal regulatory agencies, evaluation of the potential ground water contamination begins with considering those areas in Arkansas where pesticides are used and where the ground water is vulnerable to contamination. With a relatively large area of crops grown in Arkansas and only limited financial resources available for chemical analyses by state and federal …
