TL;DR
Right now you can't plant trees on landfill. Add a new soil that lets you plant trees anywhere on nauvisWhat?
Tree farms on nauvis are restricted to natural soils, and you can't build them on landfill. Not only is this a little annoying when trying to get trees close to pollution sources (seemingly the best way to absorb pollution), it's also annoying when you're tearing up concrete and can't tell whether there will be natural soil or landfill beneath it.I suggest a new nauvis soil type, Overgrowth Nauvis Soil. This recipe would include normal landfill, fish and biter eggs, possibly other things. It'd let you put your tree farms in former lakes.
