A quick tour of the results of the latest biochar 'meta-analysis'

We planted our sunflowers (Russian Giant) into the test beds very late this year, in early August, after the Charlotte potatoes came out. The thinking was simple; sunflowers need lots of water and nutrients and they will really test the different soil additive mixes.

SoilFixer explores the development of a fantastic raised bed, container and planter mix based on compost, biochar, soil and colloidal humus. With great results, 100% peat free and re-usable every year, it is looking like a strong new product area.

Our tester Paul has been busy filling his Super Composter with a mixture of materials from general garden waste from his smallholding, to household scraps, coffee grounds and sourdough starters from the kitchen.

We’ve been testing our soil additives by growing radishes in five sets of beds. And it makes interesting reading!

June was the first month of testing for our Super Composter panel. The first task was to set up their prototype bins, each was supplied in flat-pack format.

We have many gardeners and allotment owners testing samples of SF60 to see what impact it has on vegetable growth.

Jason Daff (one of our testing community) set up trials using Levington’s F2 commercial growing media as the control. He added 10% and 20% SF60 with the F2. A fourth set of seeds were grown with F2 topped up with a commercial slow release fertiliser (Osmocote).
