| Over-application of manure on cropland can cause water quality degradation. This paper reports a modeling approach for assessing tradeoffs among manure storage and handling systems as they relate to the nutrient loadings in cropland runoff, including nitrate losses to groundwater. The CREAMS simulation model provided estimates of nutrient losses. A linear optimization model was used to determine the income-nutrient loss tradeoffs. Six-month storage was profitable for farmers with average-size dairy herds, but compared to daily spreading caused increased nitrate leaching through the soil to groundwater resources. Twelve-month storage systems decreased farm profitability while decreasing the total nitrogen losses from farm fields. |

| Expected prices and expected net returns from cropping activities are used to estimate soybean acreage response in the Northeast. Futures prices and lagged cash prices constitute proxies for price expectations. Expected net returns appear as good or better than expected prices for estimating acreage response. Short-run and long-run elasticities of soybean acreage with respect to expected net returns from soybeans are estimated as 0.5 and 1.6 for the northeast region. Soybean acreage appears less responsive to changes in expected net returns than to expected changes in prices. |
