分かりにくいかも知れませんが、これは耕うん機をかけている場面です。毎年している必須作業なんです。
分かりやすく説明すると、鍬にあたる耕うん機の爪をエンジンの力で回転させて土を撹拌するのです。例年では爪が半分くらいしか土の中に入って行かないのですが、今年は8、9割が土に潜っています。それだけ土が柔らかくなっているんです。今まで屈かなかった深い部分も耕すことができています。
土壌消毒をやめてから、ようやく有益微生物が活発に動いている一つの証拠でもあります。空気と有機物をたくさん含んだ良い土になってきています。
耕うん機が本当に軽くなって、作業が楽しいし、疲れ方も随分軽減されました。今から種まきが楽しみです。
You may hardly understand what this is. This is a scene we were cultivating our field. We have to do this every year.
To give a detailed explanation, the tiller’s engine rotates the claws which are like hoes, and they make the soil turn over. In usual years, the claws could go into the soil only halfway. However 80 or 90 percent can go into the soil in this year. It means that the soil has got softer, and we can cultivate deeper parts of the soil which we had never reached ever.
After quitting soil sterilisation, this is an evidence which many microbes are working actively. It means that a lot of air and organic matter exists in the soil, and it is getting better in the condition.
We can drive a tiller easily and enjoy it, and besides we get to feel tired lighter. We expect for now to sow the seeds in September.
