Maybe your Purdue University Corn & Soybean Field Guide is so worn from use some pages are tearing. Maybe it's yellow and brittle from laying in the windshield in the hot sun in between items that you use it. Or maybe you got one of the 2009 collector's editions with pages missing. Whatever the cause, the best bargain in all of agriculture is now printed and available, and that's no joke!
The book referred to as a reference more than any other by Indiana Prairie Farmer writers and columnists both on the Web and in print is the Corn & Soybean Field Guide. It's prepared and published by the Purdue Crop Diagnostic Training and Research Center, headed up by Corey Gerber. The clinic still holds training for farmers and fertilizer and herbicide dealers and applicators at special field days every summer.
These days, they utilize what they call the 'goof' plots, where they make mistakes on purpose so that they can teach crop diagnostic techniques, but they also utilize classrooms and alb facilities at the Beck Ag Center. Both the plots and the Beck Ag center are located at the Purdue Agronomy Research Center west of West Lafayette.
The 2011 edition features corn and soybean grain on the cover. It's 318 pages of pictures, scouting information, conversion formulas and about anything you nee dot answer questions while planting, harvesting, spraying or scouting corn and soybeans in Indiana.
For example, on page 125 you find moisture conversion factors for soybeans. If you harvested at 13%, there were 60 pounds per bushel. But if you harvested at 7% during this past dry fall, that bushel volume weight was only 56.1 pounds. It's all spelled out along with the conversion formula so you can make quick decisions if this is the information you need.
Or maybe you want to know want downy mildew looks like on a soybean lead. There's a clear, crisp color picture on page 156, plus a description of the disease. Pages of pictures and descriptions of other important soybeans diseases are located in the same section of the Guide.
