The Interactive Agronomy Handbook
The Illinois Agronomy Handbook has provided farmers and their advisers
with recommendations for optimum production of corn, soybeans, small grains,
and forages for more than a quarter of a century. Over the years, this publication
has been revised regularly to provide up-to-date and research-driven information.
A companion Website, the Interactive Agronomy Handbook at http://aces.illinois.edu/iah/,
has been developed to supplement the print version of the handbook. The
Website provides interactive decision aids that enhance the handbook’s
utility by helping producers perform calculations and access the most recent
data available as they make critical crop production decisions. The site
also serves as a portal to information on Illinois farming.
Key features of the Interactive Agronomy Handbook include:
- full-text chapters from the latest edition of the print handbook.
- calculators that enable users to perform the agronomic calculations
described and demonstrated in the print handbook. These include nitrogen
rate, limestone, seed drop rate, replant decisions, stand counting, and
yield estimation. Some allow users to plug in values and to save results
for later use.
- databases that allow users to access large storehouses of information
and input this data into the calculators. For example, the climate database
allows farmers to estimate precipitation, temperatures, corn growth stages,
and pest emergence for specific locations.
- entirely new content such as Soil Plan and Nutrient Management that
provide soil fertility recommendations designed to optimize crop yields.
They help farmers manage nutrients based on soil test results, soil type,
crop, anticipated yield, and federal rules.
- links to related high-quality resources from the Department of Crop
Sciences and sources.
- a CD-ROM version with all capabilities of the Website.
The Website also provides experimental features that break new ground,
- the CFAR Toolbar integrates tools from our site with tools from our
- county-specific pages offer yield, climate, and spatial data, including
some digital soil maps.
- wireless access through cell phones and PDAs enables the use of some
IAH resources in the field.
