Alt— Lancaster Farming, Saturday, May 22,1982 How best to control water pollution from small feedlots COSHOCTON, Ohio - Many cattle on small farms in the eastern United States are being fed on small paved lots, and runoff from these lots often carries pollutants into nearby streams Although we do not know exactly how serious the problem is, federal tax funds and farmers’ dollars are being spent to reduce runoff from these small feeding operations, reports Agricultural Research Service William M Edwards, soil scientist at the North Appalachian, Experimental Watershed, designed a 3-year study to evaluate the runoff quality from a typical small paved feediot and from an unpaved feediot He also developed and tested facilities to control pollutants in the runoff Each October for.! years a 2,600- square-foot feediot was stocked with 56 steers that were fed corn silage until March Then the ration was gradually shifted to shelled corn for the last 3 months of growth The animals were removed in small groups as they reached market weight A 400-square-foot setting basin caught all runoff from the paved lot Overflow from the basin then moved in sequence through two filter strips of fescue sod, each 100 feet long by 15 feet wide Runoff material was evaluated at four points as it came off the Vegetable Co-op holds annual meeting BERWICK - Berwick Vegetable Cooperative’s 29th Annual Dinner Meeting for members and area farm leaders will be held Saturday, June 26, here at the Maria Assunta Hall. The Cooperative's guest speaker of the evening will be E. Chester Heim, Deputy Secretary of Agriculture. His speech will be entitled “Structuring a Successful Marketing Program.” Heim has a lifetime experience in farming and agriculture. Just prior to being appointed Deputy Secretary of Agriculture in February of 1979, he was employed by the Pennsylvania Farmers Association as Manager of the Public Affairs Department. The evening’s activities begin with registration and a cash bar at 6 p.m. dinner at 7 p.m., Heim’s address at 8:30, followed by the annual business meeting. f~ Sensenig Spouting I R.D. 3 Box 23 s New Holland, PA I Seamless Spouting Now in Seven Colors Old Style Half Round Spouting | Aluminum & Vinyl Siding I Soffit & Fascia & Window Capping r Sheet Metal Work & Roof Ventilators I Nelson S.

Owens, and agricultural engineer Richard K White of Ohio State University, analyzed the water for chemical oxygen demand, biological oxygen demand, total solids, total and soluble nitrogen, phosphorus, and potassium The settling basin was verj effective in reducing solids and nonsoluble materials in the runoff.” Edwards said The filter strips were more effective in removing the soluble ammonium nitrogen, phosophorus, and potassium Reduction of these chemicals was as effective in the second filter strip as in the first, indicating the value of the ad ditional filtering area under these test conditions ” Concentrations of all materials being measured were higher in the latter part of the feeding cycle when the ration was higher in shelled corn than in coin silage Animals fed corn silage produce a coarser textured manure, which is more easily retained in the settling basin after each runoff event Runoff from the paved lot equalled about two-thirds of total precipitation while runoff from the unpaved lot equalled about one- Why we are selling- due TO A CHANGE IN OUR FARMING ENTERPRISES, WIS ARE REGRETFULLY FORCED TO LIQUIDATE OUR ENTIRE SHEEP PROGRAM.
