Soil is a natural body consisting of layers (soil horizons) that are primarily composed of minerals (i.e., sand, silt, clay), mixed with at least some organic matter, which differ from their parent materials in terms of their texture, structure, consistency, color, chemical, biological and/or other characteristics.
Those are elements?
You could make DIRT without mods by combining elements A.K.A mixing. But honestly DIRT should be included into TPT for asthetic reasons. It doesn't have to have plants grow from it! I think that saves would be better than one's that have to use other particles and deco them. Not everybody is amazing at deco!
