I had some soil with me while going to dig some acre clay and i dumped it onto the clay node.
In the place where the soil increased the height of terrain I dig now soil of quality of the soil I dumped (tho its hard capped by this char survi so not sure if the quality is based on the soil i dropped or the clay node also have soil quality? the clay Q is 10,10,10 and soil was something like 10,14,11).
Also those 2 terrains cant be recognized so i dunno where would i dig clay, and where soil.
Ok so I came on the place with char with high survi, and i gather ~10,45,20 soil from that place. So I assume I changed my acre clay node into soil node in the place where i dropped the soil.
