McNitt, and H. Jones; Date: 2003; Summary: Nitrogen and phosphorous losses from manure and fertilizers were modeled for dairy farms (very small, small, medium, and large dairies) with varied stocking densities (6.4, 7.7, 3.5, 2.2 cows/ha) and fertilizer rates (baseline, nitrogen, high and low phosphorus) to identify the combination of management practices that could reduce water pollution, on a northeastern Texas watershed.

Total revenue, total cost, net returns, livestock rations, sales, and cost of individual production ...; Agrovoc Control Words: Riparian zones, Water quality, Stocking density; View more details about this article
