Forage crops offer an excellent solution to filling the forage gap in the autumn and winter months when grass growth slows down. In addition, forage crops are an excellent break crop, increase organic matter and allow for a return of the grazed nutrients to the soil. Many forage crops can offer a high dry matter yield, making them very cost effective to grow.
Field Choice
- Soil type – capable to create a fine seed bed for sowing, light to medium free draining soil
- Shelter –for the animals to shelter in the winter
- When land is available e.g. after silage or spring
- Is there a field that is currently performing poorly that would benefit from a break crop?
- Have available water for grazing animals, ensuring there are no environmental limitations such as poaching of water courses, etc.
Crop Choice
There are various forage crops available, when looking at which crop to grow, there are certain attributes to think about,
- The length of time it takes to grow before it can be utilised
Crop Sown Utilised after sowing Comments Stubble Turnips April – September 8-13 weeks Can grow as a catch crop (summer and autumn). Less winter hardy. Forage Rape May – August 10-12 weeks Quick growing, not cold tolerant. Hybrid Brassica April – August 10-12 weeks Summer, autumn and winter grazing. Kale April – May 22-30 weeks Cold tolerant. Swedes April – June 24-31 weeks High dry matter and cold tolerant. Fodder Beet Late March – Late April/early May 25-30 weeks Very high yielding dry matter and energy and cold tolerant. - How winter hardy the crop is

*some of the above require careful management when being utilised sruc.ac.uk/media/e24nyng4/outwintering-strategies-booklet-497866-sep-2022.pdf - How the crop would fit in with your rotation Brassicas should only be grown 1 year in every 4/5 in a crop rotation to limit diseases such as club root. The majority of fodder crops belong in the brassica family, with the exception of fodder beet, which belongs in the beet family. If crops such as oil seed rape are in the farm rotation, careful planning will be required here.
