The Rotational Benefits of
Forages: A Review

Background

"In 1950, forage crops occupied 4.5% of our cropped acreage in Manitoba. Nevertheless, the best advice obtainable indicates that at least 20% of our acreage should be sown to these crops to meet the need of our soil and livestock."

- from 1951 Bulletin of the Manitoba Department of Agriculture and Immigration

"Today, the estimated percent of arable cropland rotated with forages ranges from 5 to 15% on the northern Great Plains."

The benefits of forages in crop rotation have long been recognized. In the past, forages were associated with "stable or balanced" agriculture. Modern research tells the same story, but due to less diversified production systems, the benefits of forages are often not taken advantage of.

The Value of Forages to Agriculture

Forages offer a direct value to agriculture by being a large part of the rations fed to livestock. For example:

Livestock % Forage in Ration
Beef: cow-calf 98
Beef: finishing 25
Dairy 60

Forages also offer an indirect value to agriculture. Forages offer benefits by improving the soil, crop yield and quality, suppressing pests and reducing the impact of agriculture on the environment to name a few.

A quote about alfalfa...

Today, upon the threshold of an era of infinite promise, who is bold enough to measure the civilizing values of such a plant upon human destiny?

Geo W. Hendry, 1932

Recommendations

  • Consider rotating short-term forage stands to benefit the whole farm.
  • In not interested in traditional forages, consider cover crops or forage seed crops.
