Back in 2007 we took on the tenancy of Sacrewell Farm near Peterborough, just off the famously fertile Fens, to grow veg and pack our veg boxes for customers in the east of England. After a lifetime in Devon’s restrictively small, hilly fields I was seduced by the prospect of farming 500 acres of level, freely draining, relatively uniform soil; surely this would be easy. It turned out that the land was exhausted, flogged by 20 years of continual conventional cropping with potatoes and cereals. We set about sowing grass clover leys to restore natural fertility, planting an orchard and hedgerows and converting to organic methods; early crops were disappointing but eight years on our farm team are getting better crops each year as the life comes back into the soil and we learn which crops suit the silty loam. The harder climate and lower humidity means we get much less fungal disease so we now grow most of our onions here to avoid the mildew that inevitably hits us in damp Devon, and this year’s crop is looking very good.
Watching the transformation of Sacrewell has made me appreciate how much farms on our relatively small island can vary as a result of their natural geology and how the soil has been treated. In Devon the mixed farming my father employed for 50 years has protected the loamy, balanced (if shallow) soils, and the thick hedgerows are a blessing; it turns out that they help keep insect pests under control by providing habitats for insect predators to overwinter. In the east, while we have created a rich, biodiverse farm at Sacrewell, monocultures and huge fields are the norm where a ‘hedge’ is a sparse, stunted row of thorns. While their influence means we still have rapid outbreaks of aphids here that we never see in Devon, the change in the past eight years has been incredible; an RSPB survey last year counted 70 species on the farm including lapwings, corn buntings, grey partridges and red kites.
Organic farming means treating each farm as an individual and finding its virtues; it has taken us a few years to appreciate them, but now we are undoubtedly bringing out their best.
