<br />IV, ECONOMIC MONITORING AND EVALUATION <br /> <br />N <br />r..:! <br />,:::.. <br />rv <br /> <br />A. Setting & Methodology <br /> <br />Data was collected on III contracts using the <br />Salinity Planning Worksheet and copies of the <br />contracts. SPW collection has heen for all . <br />contracts since 1992. Due 10 workload and need <br />for database maintenance, NRCS plans to utilize <br />the individual economics on-fann analysis on a <br />voluntary basis rather than as a program <br />requirement in the furore. Detailed economic <br />information was collected from producers who <br />expressed an interest in a more in depth <br />evaluation of effects from installing improved <br />irrigation systems. <br /> <br />The average number of acres in a contract is 43 <br />acres. Major crops in the area are alfalfa, and <br />pasture grass. <br /> <br />8, Changes in Agricultural <br />Production Items <br /> <br />Table 5 Effect of Salinity Control Practices <br /> <br /> Before After <br />Group delivery systems <br />System type unlined ditch pipeline <br />Average Units served (#) 6.57 6.57 <br />Ave"lle System length(ft) 6,139 4,432 <br />Labor per contract (hours) 67 <7 <br />Farm delivery systems <br />System type unlined ditch pipeline or <br /> lined ditch <br />Average System length (ft) 5,508 3,182 <br />Labor per contract (he) 73 II <br />Field application systems <br />System type unlined ditch gated pipe <br /> or sprinkler <br />Operation and <br />Maintenance (hrs/acn!!) 8 4 <br /> <br />Table 6 System Installation Cosls <br /> <br />Contract Total <br />Cumulative <br />FY 9li Tn Date <br /> <br />Avcl'll.P:C Total Cost <br />Total 23,090 <br />Government 15,008 <br />Producer 8,081 <br /> <br />31,091 <br />20,209 <br />10,882 <br /> <br />A venUle A "nual System Cost <br />Total 3,071 5,141' <br />Government 1,996 3,34l <br />Producer 1,075 1,799 <br /> <br />Oner3tion find Mflintenance <br />582 1,001 <br /> <br />Cost Per Ton of Salt reduced <br />Total 68.29 77.76 <br />Government 4439 50.54 <br />Producer 23 90 2722 <br /> <br />Per Acre <br />Cumulative <br />IT 95 To Da.te <br /> <br />965.60 <br />627.64 <br />337.96 <br /> <br />152.90 <br />99.38 <br />53.52 <br /> <br />2559 <br /> <br />692.98 <br />463.44 <br />249.54 <br /> <br />77.76 <br />50.54 <br />27.22 <br /> <br />22.97 <br /> <br />, Practice cost amortized over !:he life of each practice at <br />7.75 percent interest rate.
