This publication is a comprehensive guide to field crop production. The latest recommendations on all aspects of producing field crops are included. Information on tillage options, soil management, variety selection, seeding, fertility, harvest, storage and more make this an important tool for a better bottom line. Descriptions of crop problems and more than 200 colour photos help with quick diagnosis. Diagnostic guides and scouting calendars make this publication a useful resource.


Field crops are produced in Ontario under diverse soil and climatic conditions. The goal is sustainable crop production using proven techniques that include: scouting and pest management, soil and fertility management, tillage, variety selection, planting and harvesting practices. These techniques also take into consideration the responsible use of natural resources. These, combined with in-field trials, help producers determine which practices warrant adoption. Good agronomic practices are essential for helping Ontario farmers produce food, fibre and fuel. Successful crop production is dependent upon many inter-related management practices. A little good luck and good weather helps too.

Publication 811, the Agronomy Guide for Field Crops is designed to be a technical resource for field crop production.

This third edition replaces the 2009 edition. It has been updated with current Ontario research and production guidelines as approved by the Ontario Soil Management Research and Services Committee (OSMRSC), which is represented by researchers, industry, producers and extension staff.
