Bulb grower hails reduced costs with fertiliser applicator

The Horstine Airstream's ability to place fertiliser precisely coupled with its versatility has helped to reduce costs at a Cornish bulb-growing enterprise.

The need to drive down costs was one of the main findings of a review carried out by Maurice Crouch (Growers) last year.

The crop is grown mainly for the flower trade and accounts for 320ha/year of the 400ha the company farms in a triangle from Lands End to Falmouth up to mid Cornwall, from its base at Roscarnick Farm, Truro.

Bulbs are grown in beds with two ridges per bed. Planting is on a three-year cycle, ideally in August-September, when a starter potash/phosphate compound is applied at the same time.

In the review, the fertiliser application method was particularly scrutinised. Farm manager James Walkers said: "We were broadcasting it on the surface and turning it in with the bed tillers.

"Fertilising all the areas we don't plant created a lot of waste. It also fed the weeds.

A review of the different spreading systems available indicated that the Horstine Airstream offered the potential to save money - directly on product and through the elimination of an operation."

The Airstream is capable of delivering solid fertiliser to any rear-mounted implement. It has a 1,600 or 2,200-litre hopper, front linkage mounted on a heavy-duty frame. A single tractor spool drives the positive displacement metering unit.

I find myself in a difficult situation. A few weeks ago I was fortunate to be present to hear details of imminent changes to regulations concerning Oak Processionary Moth (OPM) and oak trees. I heard details, asked questions and probed the implications of these changes. That may not sound like a difficult position to be in, yet I am uneasy.

Lobby groups jumping onto fashionable campaigns, often to promote their own interests, can do much more harm than good. Take, for example, the move against black polythene plant pots and containers.
