Making compost tea

We are using 160901 to make compost tea. Although the temperature has fallen to ambient, it’s still a bit early.  This is only seven weeks old, and it’s apparent that while all the green material and plant material has gone and isn’t recognisable for what it is, the woodchip takes longer to break down. As such it will be mainly bacterial, the fungi take longer to develop. Fungi are better at decomposing woody material. But sometimes it is not worth letting the perfect be the enemy of the good.

Looking back at the success we had with the beans there is some latency of a few months between putting the compost organisms out, compared with the more modest results after only a couple of months, so we want to get this out now to do its work over the winter.

First a look at the compost, at 5:1 dilution and total mag 400x

We are using the Laverstoke Park Farm compost tea brewer, and some of their compost tea food, and a more robust mounting of the air pump than last time.

The tea was launched at about 9am and sampling it at 16:00 showed a largely bacterial mix, and not too much dense. I did find this nematode

in the brewing tea, and the original compost heap was host to some brandling worms, so it had good signs of healthy and aerobic conditions.
