Document Summary

With movement of clay there"s loss of carbonates. Evolution of ae with time leads to platy structure. Increased then decreased ph, over time becomes neutral. Increased then decreased carbonates, but still fairly high. Bt is diagnostic horizon, no bt then no luvisol. Clay pm, loamy clay, loamy silt, over sedimentary rock, level will stay constant. If there"s a lot of carbonate leaching there could be a cca horizon (secondary enrichment), if not it will stay at ck. Warmer, more bio activity, more deciduous tree, mast>8, pm underlying sedimentary rock, loamy till. Mast
