fall cover crop

Set the right trajectory for your cover crop program with the full caliber of AAC Bullet oats!


Ontario Farmer Article – research on cover crops.

” The research produced one clear result: while the nutrition value didn’t differ much between

the various species – except that the addition of peas produced higher protein levels

– when it came to yield, oats and oat/pea mixtures were head and shoulders above

the others, Deen says.”

Crown Rust – Oats play an important role as a solo cover crop or in mixes with other species. The only problem with oats is it can occasionally be decimated by Crown Rust disease. While fungicides do an excellent job of protecting oats from Crown Rust, a better alternative for oats as a cover crop is to plant varieties with the best resistance. AAC Bullet is new variety with very good tolerance to rust. At Cribit Seeds we will endeavor to propagate the latest SeCan varieties and make them available as fast as possible as part of our Oat Rust Buster initiative. The rust pathogen keeps adapting so we need to step up our game making the best genetics available…especially for cover cropping when a fungicide may be cost prohibitive. The chart to the right, while only one site indicates the power of better genetics.

Five Reasons to Plant a Cover Crop

1. Fix or Sequester Nitrogen
Grass species such as oats or rye will use up, or sequester, excess nitrogen left over in the soil. Once these plants start to break down they will release the nitrogen and make it available for the following year.
Legumes such as clover and peas have the ability to produce, or ‘fix’ nitrogen. Nitrogen fixation rates will vary from 20-80 lbs/acre.

2. Improved Soil texture
Plants such as clover and tillage radish have long tap roots that help break up crusting and compaction issues in your field. This also helps with drainage. Plants such as rye, oats, and peas will provide more top growth and fibrous roots. This bio-mass may be incorporated into the soil to increase organic matter.

3. Control of soil erosion
Wind, slope, and excess water can all play a part in causing soil loss. Planting a cover crop will help to control these issues while increasing organic matter.

4. Weed Control
Cover crops are a natural form of weed suppression. Thick cover crops will shade out unwanted weeds and capture carbon without increasing the ‘weed seed bank’.

5. Organic Matter
Green manure or cover crops increase the amount of organic matter which encourages earthworms to flourish. Worms bore tunnels through the soil breaking up compaction and improving drainage. Improving their food supply helps to increase the population of these natural species that in turn improves soil quality.
