The United States (US) is a market leader in many of the world's major crops. Understanding where and when major US crops are grown can help Canadian farmers market their crops. Reports on US seeded acreage, growing conditions, weather forecasts, production reports, and harvest progress are all relevant for Canadian farmers. Some reports, particularly in farm papers, are interesting news but they have little market significance. Other reports are very important. Knowing where the various crops are grown can help separate important market news from "market noise".

This article will show where each of the major US crops is grown. It will also show when the crops are planted, when they are in their reproductive state, and when they are harvested.

Corn, Soybeans, Barley, and Oats

The largest US crop in terms of total production is corn, the majority of which is grown in a region known as the “corn belt”. The second largest crop grown in the US is soybeans. As with corn, soybeans are primarily grown in the Midwestern states. The US barley crop is of most interest to Canadian malt barley growers. US barley is grown over a wide area geographically and the US produces about 60 per cent as much barley as Canada. Although the US produces some oats, Canada is the world’s largest oat exporter and supplies about 70% of the oats imported into the US. Figure 1 and Table 1 show the average annual production of each crop in the US, where they are grown, when they are seeded, when the crop flowers or heads, and when it is harvested.

The third largest crop grown in the United States is wheat. The US produces hard red, soft red, and white winter wheats and hard red and durum spring-seeded varieties. The US also produces very small amounts of white spring wheat. Table 2 and Figure 2 show the primary growing areas for each type of wheat, including the average seeding, heading, and harvesting dates.

Market Noise

The goal of this Agricultural Marketing Manual is to help farmers to decide what is "market noise" and what is market news. For example, if you hear a report that says that the corn crop in Texas is suffering from severe drought, you will know that is "market noise" rather than significant market news. Texas doesn't produce a great deal of corn. Or if you hear that the soybean crop in northern Alabama has been damaged by a frost, you'll know that is "market noise".
