Cover crops – silver bullet or white elephant?
10 August 2015
Ask any arable farmer if they want to improve soil fertility and structure while reducing soil erosion and nutrient loss, then they will say ‘yes’. Equally, ask any arable farmer if they want to increase costs and summer workload while adding to rotational conflicts, then they will say ‘no’. And herein lies the reason why the recent revival of interest in cover crops has reignited one of the classic farming debates.
It’s not just a case of whether you include them in your plans or not. Each type of cover crop has its own characteristics, so choice of species or mixture and their suitability to a particular system or objective can be equally as controversial. So too can establishment and destruction methods – spray off, cut, graze or direct drill? But which drill is best? What are the EFA rules?…and the list goes on.
So, it’s not surprising that discussions around the pros and cons of cover crops, which to go for and how to manage them has fuelled many a discussion on the Monitor Farms to date. They come up whether you start a meeting talking about soil management, crop establishment, nutrition or weed control. So, it seemed sensible to give them their own slot in the programme.
Each of the four Monitor Farms in the east region will be drilling a range of cover crops in different situations this summer so each of the groups can debate the subject further in the winter, but with the added advantage of actually being able to see, touch and hear about what worked and what didn’t.
Too much or too little? One of the many Monitor Farm cover crops being closely examined by the Stowmarket group.
The meetings where will see the cover crops, hear from the experts and debate the issues are:
- Stowmarket, 6 November 2015
- Royston, 1 December 2015
- Huntingdon, 10 December 2015
- Colchester, 9 February 2016
