The ground under Gqeberha

Gqeberha stands on sedimentary rocks rock, about 299 million years old. The rock decides the soil, the soil decides what grows, and the lie of the land decides where the rain runs off to.

Bedrock

Gqeberha sits on Permian sedimentary rock

About 299 million years old — from the age of the first forests, amphibians and reptiles.

What it is
The family that covers about three quarters of the land surface, in a thin skin over everything else. Some geological maps say only this much, which still tells you it will be layered and may hold fossils.
Weathering
Along its bedding planes, layer by layer, at a rate set by whatever the layers are made of — which is why sedimentary country weathers into steps.
Effect on soil and vegetation
Layered country with flat-topped hills and stepped valley sides. What grows on it depends entirely on whether the beds are limey or sandy, which is the question worth asking next.

Lake: Still water that layers in summer: warm at the top, cold below, with a sharp boundary between. Fish sit at the depth that suits them and move as that boundary does.
Stream: Small, cold, and shaded by whatever grows over it. Most of what lives here eats insects that fall in from the trees, so a stream through woodland is a richer place than the same stream through a field.
River: Moving water sorts itself into riffles, runs and pools, and everything in it lives where the current brings food without costing more energy than the food is worth. Learn to read the seams and you have learned the river.

Bedrock and soil figures are modelled from national geological surveys and global soil mapping, at a resolution of a few hundred metres — right for the shape of a district, not for a particular garden. River discharge is modelled, not gauged. For anything that matters, dig a hole and look.

For children: dig down through the soil under Gqeberha to the bedrock, an interactive cross-section.

What it means

The sweet spot for a vegetable garden. Nearly every nutrient is at its most available somewhere in this band, which is why it is the number every soil guide tells you to aim at.

Suited without amendment

Almost everything: tomatoes, beans, squash, lettuce, apples, most perennials and most lawn grasses.

Amending for other plants

Nothing needed. Compost keeps it here; heavy lime would push it past useful.

Workability

Water runs straight through, so it dries fast and warms early — you can work it days after rain and sow ahead of heavier ground, but it needs watering and feeding more often because both wash out.
