Growers and consultants have relied on the Purdue Extension Corn & Soybean Field Guide for more than 20 years. This is the perfect in-field reference that takes the popular guide to the next level. Purdue University specialists created this comprehensive, science-based app to help you effectively manage corn production. The Purdue Extension Corn Field Scout provides built-in calculators for seeding rates, estimating yield loss, limestone recommendations, nitrogen recommendations, phosphorus recommendations, and potassium recommendations. There’s even a section to add field notes. The Insects & Nematodes, Diseases, and Weeds sections will help you identify the common pests of corn and the damage they cause. You’ll also find sampling and management information. The Soils & Fertility section provides the latest nutrient recommendations and shows common signs of nutrient deficiencies. The Diagnosing Herbicide Injury section provides a tool for identifying herbicide injury and describes herbicide modes of action. And the Planting, Growth, & Development section provides information about identifying and predicting growth stages. This app includes hundreds of useful, high-quality images to help you diagnose problems and understand common issues in corn production.
