| Abstract/Contents: | "The turfgrass microecosystem, developed at the University of Illinois to study the fate of pesticides in turf, has been operational for the last year. The system consists of a base with a porous ceramic plate sealed into the bottom of the base. The base holds the soil; but, more important, the ceramic plate is used to apply a tension to the soil. This tension pulls the water from the soil until the remaining soil water is at the same potential as that applied to the porous plate. This setup mimics the situation found in turf. A glass atmospheric chamber rests on top of the base to form a closed system. Air moves through the chamber, and the air stream is scrubbed to remove any volatilized pesticide or 14CO2 from the microbial degradation of the radioactive pesticide. Leachate from the base is collected and analyzed for any radioactivity. Experiments on the rate of breakdown of Dacthal as influenced by soil moisture and soil type have recently been run using the microecosystems. The analysis of the soil residues is all that remains to conclude the experiment. The factor preventing more pesticides from being examined is the analysis time of the samples collected. As soon as the soil analysis of the Dacthal is completed, experiments will begin on the fate of the insecticide Diazinon. Variables such as irrigation amount and frequency, soil type, and that the microecosystems will provide valuable data concerning the factors affecting pesticide dissipation by allowing experimentation with widely differing soil types under controlled conditions. The versatility of the microecosystem has been demonstrated by the experiments of Torello in 1981 on ammonia volatilization in turf (in press) and the work with Dacthal. As experience is gained with the microecosystem, more and more commonly used pesticides will be examined and the results used to better predict the fate of a pesticide on turf." |
