A move to using narrower furrows facilitated by on-land ploughing rather than in-furrow ploughing with wider furrows could improve inversion and black-grass seed burial, according to ProCam agronomist and match plougher Kevin Pearcy.
“People are using big tyres because of compaction issues but to get these to sit in the furrow you need to plough wider furrows and inversion is not as good with wider furrows.
“Should we consider on-land ploughs where we can sit on top and use narrower furrows and get better inversion? “A smaller furrow is particularly important on clay soils,” says Mr Pearcy.
Ploughing skills are being lost in the industry and growers should avoid ploughing too fast and ensure skimmers are set correctly, he says. “If you plough too fast, skimmers are throwing small seeds into the air which can end up landing on already ploughed land.
“Check skimmers are set right. They should be set at 30-50mm deep.”
