55-160-08 4.50 ac. wheat/alfalfa/oats/corn 55-160-59 13.50 ac. wheat/alfalfa/oats/corn 55-160-62 48.89 ac. Almond Wheat/alfalfa/oats/corn total: 348.31 ac. Almond total: 48.89 ac. Total ac.: 397.20 ac. See the Irrigation Plan Map, Sheet 1 D, attached, for APN number, location and irrigation direction of the fields to be irrigated with nutrient water. All fields except the almond orchard are labeled "wheat" but will actually be rotated between alfalfa, oats, corn, and wheat. Nutrient water blended with clear water from the irrigation system flows across the field in the direction indicated by the arrows. When nutrient water irrigation is managed properly, the flow is regulated so that all the water is absorbed by the soil, and a minimal amount reaches the lower end of the field. In the event that there is excessive flow, a drainage system will return any water which is not absorbed by the soil to the lagoons, or to the upper side of the field, where it can flow over the soil again. It is recommended to periodically "deep rip" the soil to breakup any hardpan layers and facilitate root penetration. Manure solids should be applied to and worked into the soil profile to a depth of 18" or deeper. This will build up the soil tilth due to an increase of organic materials to the profile. In order to determine manure liquids and solids application each year, a field soil sample will be analyzed to monitor: • "ENR" (estimated nitrogen release) to be performed by a N.A.P.T. accredited laboratory. Nitrogen in manure solids is released over a period of approximately four years. Approximately 25% of the nitrogen content is released each year. ENR from the previous three years' manure applications must be subtracted from the current crop's projected nitrogen requirements to determine the amount to be applied. • Nitrate nitrogen, using EPA method 353.2, in order to accurately calculate amounts of solid manure required Results will be used to determine amounts of dairy pond lagoon water and/or commercial fertilizer to be added to the soil to provide a balance of elements for optimal plant growth and nutrient uptake. Manure solids are to be applied in a ratio not to exceed the crops' estimated nitrogen uptake, less the ENR from previous years' manure solids applications. °Western Design/David Avila 2001 27
