Estimating the Impacts of Storage Dry Matter Losses on Switchgrass Production AgEcon
Larson, James A.; Mooney, Daniel F.; English, Burton C.; Tyler, Donald D..
This poster estimates dry matter losses as a function of harvest method, storage treatment, and time in storage. We then calculate the cost to store switchgrass bales under alternate harvest method and storage treatment scenarios; and determine the breakeven harvest method and storage treatment as a function of biomass price and time in storage.

Switchgrass Production in Marginal Environments: A Comparative Economic Analysis across Four West Tennessee Landscapes AgEcon
Mooney, Daniel F.; Roberts, Roland K.; English, Burton C.; Tyler, Donald D.; Larson, James A..
Switchgrass (Panicum virgatum L.) has been identified as a model feedstock for the emerging biofuels industry. Its selection was based, in part, upon the observation that switchgrass can produce high yields in marginal production environments. This trait may become particularly valuable in coming years, as renewable fuel mandates begin to take effect and concerns over the food-versus-fuel debate increase. Relatively little research information exists about how management practices and production costs vary across different production environments. The objectives of this research were (a) to compare switchgrass yields as influenced by seeding rate and nitrogen fertilization rates in low-, intermediate-, and high-yielding switchgrass production environments,...

Cost Analysis of Alternative Harvest and Storage Methods for Switchgrass in the Southeastern U.S. AgEcon
Larson, James A.; Mooney, Daniel F.; English, Burton C.; Tyler, Donald D..
This study evaluated the potential impacts of dry matter losses from alternative harvest and storage methods on the costs of growing switchgrass for energy production. Data from a switchgrass bale harvest and storage experiment at Milan, TN, indicate that storage losses for covered rectangular bales were greater than for covered round bales. In addition, the cost of delivered feedstock increased with longer storage times because of larger dry matter losses. Even though storage losses were higher with uncovered large round bales, production costs were the lowest because costs of storage were minimal compared to other storage methods.

Economics of the Variable Rate Technology Investment Decision for Agricultural Sprayers AgEcon
Mooney, Daniel F.; Larson, James A.; Roberts, Roland K.; English, Burton C..
Producers lack information about the profitability of variable rate technology (VRT) for agricultural sprayers. An economic framework was developed to evaluate the returns required to pay for VRT investments. Payback variables included input savings, yield gains, and reduced application costs. We illustrate the framework with two example investment scenarios.
