<br />practices for feedlots will be cost-shared. The nutrient management plan needs to <br /> <br />include the amount of nitrates in the applied water and livestock waste and commercial <br /> <br />. application as needed for the crop being grown. <br />002452 . <br /> <br />Residue Management will increase residue to reduce irrigation induced erosion on the <br /> <br />upper 300 feet of the irrigated cropland. This will also reduce sediment on the lower <br /> <br />portions of the fields and into the Arkansas River. No cost sharing is available through <br /> <br />PL-566 for residue management. <br /> <br />Irrigation water management will be improved by changing water irrigation methods and <br /> <br />procedures. This is a non-cost share practice through PL-566. <br /> <br />Wetland mitigation practices anticipated will include approximately SO .aAcres of <br /> <br />wetland development. <br /> <br />Improved Surface Systems will be cost shared at a so-so cost share rate..- About <br /> <br />31,000 acres will have surface irrigation systems improved. An estimated 1/2 of the <br /> <br /> <br />acres will be converted to surge irrigation. Improvements include land leveling, plastic <br /> <br /> <br />pipe, on farm ditch lining, gated pipe, and related practices. Land leveling is to improve <br /> <br /> <br />irrigation water application and reduce deep percolation. Plastic pipe will be installed to <br /> <br />deliver water to surge valves, and also to gated pipe in fields proposed for shorter <br /> <br />lengths of run. PAM will be installed to improve water application and reduce erosion. <br /> <br /> <br />Total estimated cost of improved surface irrigating systems is $2,946,300 for ~federal <br /> <br />share and $2,946,300 for the local share. The management practices costs are a local <br /> <br />cost and are estimated at $8S0,000. <br /> <br />~ <br />
