"Simplicity is the ultimate sophistication" Leonardo Da VinciPhysicalWeeding a company that designs specialist physical weeding machinery as well as providing consultancy and advice on all aspects of physical, cultural and biological (non-chemical) weed management for commercial agriculture. It is owned and run by Dr Charles 'Merf' Merfield, an international organic / sustainable horticulture scientist specialising in weed management and machinery and Tim Chamberlain a pioneering and multi-award winning organic farmer from New Zealand. Our philosophy is to create exceptionally effective and reliable machines without unjustified complexity based on the premise that simple is superior. Our aim is be the one-stop shop for machinery and information on non-chemical weed mangement for commercial farmers and growers.
