less the estimated nitrogen release (ENR) from previous years' lagoon water and/or commercial <br /> fertilizer applications. <br /> Nitrogen available from ENR varies with soil temperature and moisture content, so each field's soil <br /> samples will be analyzed immediately before each planting to accurately account for residual <br /> nitrogen available for the up coming crop. <br /> In the evaluation of salinity (see Appendix C), which requires data on concentration variation over <br /> time, a statistical methodology for determining trends will be selected. The first trend analysis will <br /> be conducted after five years of data collection, and then each year thereafter. Buildup of salt in <br /> the soil is detrimental to growing crops. Consequently, the farmer will have a natural incentive to <br /> take remedial action upon'receiving a report that a salt buildup has occurred. <br /> To provide base data for future comparison and determine amounts of dry and liquid manure to be <br /> added to the soil to provide a balance of elements for optimal plant growth and nutrient uptake, <br /> water and soil samples will be taken at those locations shown on the attached soil / water <br /> sampling location maps (Appendices B and D). <br /> Details regarding soil, surface water, and groundwater sampling procedures, type of analyses, <br /> location, and frequency are presented in the "Soil Suitability Study" Report. <br /> Record Keeping <br /> The owner and/or operators will maintain records for a 5-year period that document the <br /> implementation and management of the manure (liquid and solid). <br /> F <br /> Documentation will include: <br /> Annual manure tests for nutrient contents for each manure storage containment. <br /> Current soil test results. <br /> Application records for each manure or commercial fertilizer application event, including: <br /> FContainment source ortype and form of commercial fertilizer. <br /> FField(s) where manure or organic by-products are applied. <br /> Amount applied per acre. <br /> Time and date of application. <br /> FWeather conditions during nutrient application. <br /> General soil moisture condition at time of application (i.e., saturated, wet, moist, dry). <br /> F See Page 47 for References and Bibliography <br /> ©Western Dairy Design Associates,Inc.2003 <br /> Page 42 <br /> F4 <br /> t <br />
