Gran Bretaña: Norfolk estate grows low input potato crop with no yield loss

Holkham Estate in north Norfolk successfully grew a 10ha field of salad potatoes with zero synthetic fungicide, fertiliser or insecticide applications, without any loss in marketable yield.

Harry Barnett, potato manager at the estate, notes that five years ago he would have considered such a thing “impossible” and “commercial suicide”.

“If it went horribly wrong, the risks involved with cutting out inputs would potentially see our business lose a six-figure sum across just a 10ha area of potatoes,” he says.
