Soilfixer Trial Part II – Post-Winter Check-In

This year I’m trialling two soil improvement products on behalf of the folks at SoilFixer.co.uk. The first, a Compost Humification Agent, was added to a bagful of compostable material back in December. A second bag of compostables was set aside at the same time, to act as a control.

Checking In

This past weekend, I checked in on the two proto-compost samples to see how they were getting along. The bags have been sitting around on plot #59 over the winter, so I wasn’t expecting anything to have changed massively, what with the lack of heat to kick-start the decomposition process. But as I dumped each sample out into a plastic bucket, I was pleased to see that actually there had been a fair bit of break-down, even in the colder winter conditions

Non-C.H.A. Sample

Reasonable decomposition, as it happens. Except for the tough grass stems.

C.H.A. Sample

March 2017 C.H.A. compost sample
Similar decomposition, perhaps a little darker in colour..? Hard to tell.

Hard to tell at this stage whether the addition of the C.H.A. has significantly accelerated the decomposition process, but the second sample did seem a little darker in colour. But of course, the proof will be in whether or not the trial crops actually perform better in C.H.A. compost enhanced soil.

Topping Up

Each sample was churned around, to get some air into the organic matter, before being re-bagged. I removed a couple of handfuls of tough, grassy stems from each sample. The stuff didn’t seem to have broken down at all – some shoots were even showing signs of re-sprouting – and it’s not the sort of material I want to add to the trial beds in due course. I then added a few scoopfuls of home compost from our recently-emptied bin and added more C.H.A. to the relevant mix.

Each bag will be re-aired and re-mixed a couple of times over the next week or two. Ten, before too long, it will be time to start the trial proper by setting up the four trial beds, adding the appropriate amendments (or not) to each, and planting out some of the seedlings that are already coming along in the greenhouse.

I’ll tell you what crops I’m planning to grow in the next Trial update.
