Well, I am excited to see the updates to make loam more useful, but I still find myself with an excess of loam. In fact, I found that while digging I gained about as much loam as dirt from dirt piles. There is still, however, a considerably greater demand for dirt than loam. Perhaps this could be mitigated with some kind of loam-into-dirt disassembling ability, that turns some amount of loam into dirt. I'm not sure what the proper ratio would be, but it could be a function of the blockmaker, or it could just be an action you perform on x amount of loam. So practically, we'd click on loam, select how many we want to convert to dirt (like shucking seeds or crushing rock), and then we'd get some amount of dirt out of that (perhaps consistent, perhaps random). This way higher level people who get a lot of loam can still get dirt if they need it and not worry about an excess of loam.
Possibly this could come from an upgrade card, too!
