The agronomic crop scientists at The Ohio State University are pleased to present the 14th edition of the Ohio Agronomy Guide. First published in 1966, the Ohio Agronomy Guide continues to serve as the official compilation of adaptive research results and recommendations from research and educational programs.
Ohio agronomic research programs are designed to determine responses of various crops and cropping systems to management practices and resource inputs, as well as to understand the basic biological and chemical mechanisms responsible for these responses. This basic research thrust allows us to model cropping systems and predict their behavior under a variety of management schemes. Our aim is also to continue developing technologies and cropping systems that are efficient in capturing solar energy, sustainable over time, and environmentally compatible.
This 14th edition reflects a major change in format for the Ohio Agronomy Guide. Weed control products and recommendations are printed in a separate bulletin (Weed Control Guide for Ohio Field Crops, OSU Extension Bulletin 789). Soil fertility information and fertilization recommendations for soybeans, corn, wheat, and alfalfa are also printed separately (Tri-State Fertilizer Recommendations for Corn, Soybeans, Wheat, and Alfalfa, OSU Extension Bulletin E-2567). Both bulletins are available at county Extension offices and are also available on the Internet at the Ohio Agronomic Crops Team web site: www.agcrops.osu.edu.
We will continue to supplement the information in this guide with other publications and fact sheets as necessary. For additional details and assistance, contact your local county Extension educator or one of the authors (see inside front cover). We welcome your suggestions and input for improvement of both this publication and our research and educational programs.
We would also like to thank the Section of Communications and Technology for text editing, layout, and development of illustrations.
This publication contains pesticide recommendations that are subject to change at any time. These recommendations are provided only as a guide. It is always the pesticide applicator’s responsibility, by law, to read and follow all current label directions for the specific pesticide being used. Due to constantly changing labels and product registration, some of the recommendations given in writing may no longer be legal by the time you read them. If any information in these recommendations disagrees with the label, the recommendation must be disregarded. No endorsement is intended for products mentioned, nor is criticism meant for products not mentioned. The authors and Ohio State University Extension assume no liability resulting from the use of these recommendations.
