Top spot in the 2017 ADAS Yield Enhancement Network (YEN) initiative for oilseed rape was awarded to long-term CF N-Min and N-Calc advocate Martin Smart from Wiltshire.

His yield of 6.4t/ha was the highest of 54 entries of which four of the five growers put forward by CF Fertilisers made the top ten.
Martin’s winning entry used N-Min and N-Calc to establish optimum fertiliser needs with Heartland Sulphur NPKS true granular compound chosen to deliver the winning performance.

His crop of SY Harnas delivered the highest estimated crop yield potential for his site at 70%, which was the highest of any entrant by some margin – the runner up in the initiative being 48%.

“The fact that Martin got top spot and four out of the top ten placements were also CF N-Min and N-Calc users speaks volumes for the importance of accurate N assessment and application in oilseed rape,” says Allison Grundy.

Congratulations also go to Jon Birchall of Shropshire, Chris Richardson of Lincolnshire, Charlie Steer of Cheshire and James Sardeson of Lincolnshire.
