They say knowledge is power — and in agronomy, knowledge is money, too. Get the power of both in your pocket with the Purdue Extension Corn & Soybean Field Guide
for iPad. This app provides information on planting, growth, nutrients, deficiencies and more. It also provides scouting tools to identify an array of weeds, insects, diseases, nematodes, and vertebrate pests — and information on how to manage them year-round. Built-in calculators also help you estimate yields and help make decisions on replanting.
