Uses

They can be grown for human consumption, livestock feed and as soil improving plants. They may also form part of a wild bird food mixture.

Persistence

An annual species.

Strengths

The plant produces many tillers, giving it the chance to smother out weeds. It will also grow on less fertile soils and produces good early ground cover when planted in the autumn.

Frost Tolerance

Spring and autumn varieties are available.

Sowing Rate Advice

50-70kg per acre / 125kg-175 per ha.

Ideal Sowing Time

Management

Oats can be flailed or grazed and incorporated before the next crop. As some plants break down after incorporation, The root exudates can inhibit the germination of other nearby species This is known as allelopathy. While this can be a useful situation with regards to inhibiting weed seedlings, it may reduce the germination of the following crop, especially if it is a small seeded crop. To reduce this effect a period of 6 weeks should be left before sowing the next crop.
