Application Management <br /> a <br /> The key features of a manure utilization plan include details about objectives, rates, quantities, <br /> and timing. <br /> Objectives <br /> The primary objective of a utilization program is to use the nutrients for crop production while . <br /> ` minimizing negative water quality impacts. A secondary objective is improvement of the soil profile <br /> through increased organic matter amendment. <br /> I , <br /> Rates, quantities, and timing <br /> i Solid manure will be applied with mineralization rates considered and as close to the time of crop <br /> nutrient needs as possible. Crop growth stage tables will be consulted see Appendix C . <br /> l , Solid manure will be applied: <br /> on days when winds are relatively calm so that aerosols and odors are prevented from drifting <br /> F onto neighboring areas, thus reducing odor complaints. <br /> • During periods that.will result in minimizing leaching and runoff of the manure components. <br /> F <br /> • When the soil moisture content is such that excessive soil compaction from equipment traffic is <br /> Fnot promoted. <br /> 4 <br /> O Early in the day when the ground and air are warming, as opposed.to late in the day when the <br /> temperature is dropping and the air is settling. <br /> Monitoring the Applied Nutrients <br /> At the beginning of each growing season, a soil sample will be taken and analyzed for each field. <br /> The estimated nitrogen release (ENR) from previous years' lagoon water applications will be <br /> determined for each field. Nitrogen in the manure solids contained in dairy effluent is released <br /> approximately 50% the first Year and 25% the following two years. ENR from the previous three <br /> years' dairy effluent or commercial fertilizer applications must be subtracted from the current <br /> crop's projected nitrogen requirements to determine the amount to be applied. <br /> A hand-held lagoon water nitrogen quick-tester and dispersion tables as developed by Marsha <br /> Campbell-Matthews of the University of California Cooperative Extension (see Appendix C), will <br /> be used to test lagoon waters prior to irrigating any field with lagoon water. <br /> The proodrtion of lagoon water vs dear water required for each crop will be determined from the <br /> soil analysis and the amount of nitrogen the crop requires based on the stage of crop maturity, <br /> See Page 47 for References and Bibliography <br /> O Western Dairy Design Associates,Inc.2003 <br /> F, Page 41 <br />
