These dark coloured, strongly structured, high base status soils are similar to the dark vertic soils but are physically more subdued for textural or mineralogical reasons. They are also
associated with a semi-arid to sub-humid climate and are fertile but require irrigation to be highly productive.
Natural veld on these soils provides sweet grazing. Although the structure 12 is strong it is less stable than in humic soils and the soils may be more erodible. Melanic soils
are well buffered and can be cropped intensively without needing lime to counteract acidification. (Soil forms: Willowbrook, Bonheim, Steendal, Immerpan, Mayo Milkwood,
