A new publication, Farm Energy: Case Studies – Techniques to improve tractor energy efficiency and fuel savings (PM 3063D), is now available for download in the Iowa State University Extension and Outreach Store. This publication is part of the Farm Energy: Case Study series and outlines ways for farmers to improve their tractor energy efficiency and save on fuel costs throughout the year.
"Diesel fuel is the largest direct energy cost for Iowa farmers and directly impacts profitability. Small changes in tractor management style can save several thousand dollars per year on many row crop farms without affecting field operations," says Mark Hanna, ag and biosystems engineering specialist with Iowa State University Extension. This publication provides suggestions to reduce fuel costs such as shifting up to a higher gear and reducing engine speed, adjusting tillage depth, decreasing travel speeds, correct tire inflation, dual vs. single tires and mechanical front-wheel drive recommendations.
ISU Farm Energy explains ways farmers can reduce fuel costs
The Farm Energy publications are part of a series of farm energy efficiency resources developed by the ISU Farm Energy team. This outreach effort aims to help farmers and utility providers to improve on-farm energy management and to increase profitability in a rapidly changing energy environment.

New "Weed Identification Field Guide" from ISU Extension
Also, Iowa State University Extension has released a new version of the Weed Identification Field Guide, first published in 2010, to assist producers and agronomists with accurately identifying weeds in Iowa corn and soybean fields. The Weed Identification Field Guide, 2nd Edition, includes additional weed species and updated information on herbicide resistance management. The guide is now available for purchase online from the Iowa State University Extension Store.
Kristine Schaefer, contributing author of the publication and pesticide safety education program manager at Iowa State University Extension and Outreach, said it was important to amend information about herbicide resistance and management from the first edition, as issues continue to develop. "One weed added was Palmer amaranth, a new weed to Iowa and one that has shown resistance to glyphosate and other herbicides," says Schaefer.
Provides updated weed and herbicide resistance information
The 108-page booklet is organized into five sections: weed management, grass weeds, broadleaf weeds, other weeds, and glossary and index. Each section includes supplemental identification descriptions, enhanced photos, and tools for correctly distinguishing weeds that have similar characteristics.
"The guide is intended to help producers and agronomists identify weeds in the field without having to go back to the office or check online to confirm identification," says Schaefer.
The pocket-sized guide contains 35 illustrations and more than 250 high-quality photographs of weeds found in Iowa. Funding for the development of the guide was provided by the United Soybean Board Take Action program and the Iowa Soybean Association. Printed copies can be purchased online through the Iowa State University Extension Store for $10, and the PDF version can be downloaded for $5.
