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, such as:
- the CFAR Toolbar integrates tools from our site with tools from our partner projects.
- 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.
