堆肥発酵実験の経過です。
From Taiki-cho, some progress report on compost fermentation experiment.
今回は空気を送入しつつ発酵させる堆肥と、そのまま発酵させる堆肥とで比較実験していますが、空気を送入した場合の1日当たりの発酵熱による堆肥の温度上昇が平均3.37℃、そのままの場合が平均5.9℃で、空気を送入しない方が発酵が進むことが分かりました。
We are testing to see how the compost fermentation is affected when a flow of air is sent through them. The temperature of the manure with the air pump raised 3.37 per day, while the manure without the air pump raised 5.9 per day. It seems that fermentation runs faster without the flow of air
堆肥の発酵には空気が有効との話だったのですが、過剰な空気は堆肥を乾燥させ、冷ましてしまうようです。
The hypothesis was that air flow agitates compost fermentation, but it seems that excessive air flow dries the compost and cools them.
今度は発酵が停滞しかけた時に、堆肥を切り返し撹拌させる代わりに、空気を送入するといった手法が有効なのか否か、確認してみたいです。
For the next experiment, we plan to send air flow to the compost after the fermentation decelerates instead of turning them over and stirring them to agitate more fermentation, and test to see how effective air pump is.

ところで、メムメドウズの空は変化が劇的で毎日気持ちがいいです。
The sky in Memu Meadows changes dramatically with the time of the day. Beautiful.
