Producer Machinery And Labor Sharing Arrangements Workshops, Roger Ginder, William M. Edwards, Georgeanne M. Artz, Darren H. Jarboe Jul 2016

Producer Machinery And Labor Sharing Arrangements Workshops, Roger Ginder, William M. Edwards, Georgeanne M. Artz, Darren H. Jarboe

William Edwards

Four case studies were developed for Iowa farm operations that have successfully used machinery and labor sharing arrangements for intergenerational transfer of farm assets. Results were shared at workshops and through publication of a resource manual.

Combine Harvester Econometric Model With Forward Speed Optimization, Nathan E. Isaac, Graeme R. Quick, Stuart J. Birrell, William M. Edwards, Bruce A. Coers Jul 2016

Combine Harvester Econometric Model With Forward Speed Optimization, Nathan E. Isaac, Graeme R. Quick, Stuart J. Birrell, William M. Edwards, Bruce A. Coers

William Edwards

A combine harvester econometric simulation model was developed with the goal of matching the combine forward speed to the maximum harvested net income per acre. The model considers the machinery management costs of owning a combine and platform header for harvesting wheat. A statistical Design of Experiment (DOE) was used to evaluate the model using tri-level variables; the medium values constituted the model base case. Of the 27 input variables, the optimum speed was significantly influenced by the crop area, G/MOG ratio, grain unit price, field yield, field efficiency, grain moisture content, probability of a working day in the post-optimum …

Economics Of Residue Harvest: Regional Partnership Evaluation, David W. Archer, David J. Muth Jr., Jacob J. Jacobson, Douglas L. Karlen Dec 2011

Economics Of Residue Harvest: Regional Partnership Evaluation, David W. Archer, David J. Muth Jr., Jacob J. Jacobson, Douglas L. Karlen

Douglas L Karlen

Economic analyses on the viability of corn (Zea mays, L.) stover harvest for bioenergy production have largely been based on simulation modeling. While some studies have utilized field research data, most field-based analyses have included a limited number of sites and a narrow geographic distribution. An Iowa case study is developed illustrating the use of data extracted from a database of geographically distributed field studies for a region-specific economic analysis. The analysis utilizes grain and residue yield and associated management information from two Iowa field research sites that are Sun Grant Regional Partnership locations associated with the Corn Stover Regional …
