OVERVIEW

Pete Olds' family has been farming at Cornhill Farm near Camborne, Cornwall, since 1912. Over that time, the farm has transitioned from a typical mixed farm to what operates today as a circular business – comprising arable, 17,000 free-range chickens and environmental stewardship.

QUESTIONS & ANSWERS

What is your biggest weed problem?

While there is blackgrass and ryegrass in the area, these weeds are not key concerns for us. Our major issues are wild oats and brome, as well as some more recent issues with corn marigold.  

What is your standard programme for controlling weeds?

With a mixed picture in terms of weed burdens, it's important to catch the weeds early, mix our chemistry, use multiple treatments where needed, and employ cultivation techniques like rotational ploughing to help control weed growth and prevent resistance. 

FARM FACTS

  • Location: Cornhill Farm, Cornwall 

  • Arable hectares: 160ha 

  • Soil type: Sandy loam over shale 

  • Crops in rotation: Winter wheat, winter barley and a break crop – usually a brassica 

  • Fertiliser regime: Poultry and muck spread pre-drilling, base NPKS fertiliser in the spring, followed by a compound nitrate-based NS fertiliser, with a three-way split on the wheat and barley. The latter splits are variable rate, and calculated from satellite mapping on Omnia

 

TOP TIPS FOR TACKLING STUBBORN WEEDS

  1. Keep mixing up chemistry to avoid resistance issues 

  1. Catch weeds early to avoid over-reliance on chemistry 

  1. Don’t forget about the plough – it's a brilliant tool to help bury weeds
