It could also come as a result of what the clones have been exposed to, both during their training on Kamino, and their experiences across numerous planets during the war. Commander Levet, for an example of the latter, spent time among the farmers of Qiilura and learned to appreciate the craft. Cut Lawquane, I suspect, simply stumbled into it: there alone on Saleucami, he wasn't likely presented with very many opportunities to make use of his military skills, but this kind Twi'lek woman who appears to have taken him in at the start of their relationship, was already in possession of a functioning farm. In the case of the former, as we're all aware, the Cuy'val Dar had a noticeable impact on the clones, even those they didn't personally train. Several of the Mandalorian members, and even a number of the non-Mando sergeants, may have had a background in farming that seeped down to the clones within their sphere of influence. Both Commander Bacara and Sergeant Fox were influenced by the Journeyman Protector ways of Cort Davin, for instance, and took away the methodology of a Concord Dawn lawkeeper.
