Interested in Intercropping?
Read about our ‘plant teams’ field lab
Soil Association Scotland collaborated with the James Hutton Institute in 2018–2019 on a field lab exploring the potential that growing different crops together has to increase yield, reduce inputs, tackle pests and improve soil health in Scotland.

Field lab member Doug Christie had been successfully growing plant teams for several years at 500-acre mixed arable and livestock, partly organic, Durie Farm in Fife.
Doug said: “I started five or six years ago to get more diversity in the crops I grow, partly for benefits you can see, like soil health and cutting back on input costs.
“I’ve grown spring oil seed rape and peas together, for example, vetch and spring oil seed rape, and beans and oats.
“It’s drastically cut my input costs – I’ve hardly needed to spray those fields at all with fungicides or herbicides and I don’t need nitrogen fertiliser. I’ve had no pests on my oil seed rape – no pollen beetle damage or flea beetle – so I’ve used no insecticides. In terms of yield it’s hard to say but I’ve had less from my beans on their own than the beans and oats together.
“I’m also interested in sustainable farming, and there are wider benefits like carbon sequestration and biodiversity.”

James Hutton Institute researcher Ali Karley was also a field lab member. She said: “Growing different crop species together is not a novel idea, but there’s not enough information out there about what varieties people should use and for what purpose. For example, which cereal/legume mix for forage or silage? What if I want really high protein? And what would be right for local soil conditions?”
The field lab fed into EU projects DIVERSify (though James Hutton) and EU-ReMIX (through SRUC's researcher Robin Walker) that aimed to answer these questions, and make consistent advice and tools available. Participating farmers and land managers trialled a plant team (e.g. peas and barley), comparing it to a nearby monoculture and sharing basic crop performance data.
