Humus soil, an organic substrate for undergrowth

Is the soil in your garden humus-rich? Here's an overview of what you can Planting according to soil type.

Humus-rich soil is composed of sand, clay and at least a tenth of humus (decomposed plant organic matter). It's the soil of forests and undergrowth. Like peat soil, this substrate is acidic.

Humus and the microorganisms that make up humus soil make it highly fertile. Humus is also rich in nitrogen and carbonate.

Humus soil retains the water, nutrients and trace elements necessary for plant growth. Its acidity makes it an ideal substrate for growing heather plants.

Very light and non-sticky, this soil does not clump or agglomerate. It is therefore easy to work.

Humus soil can be recognized by its dark, even black color. This is due to the decomposition of various plants. When moist, it gives off a mushroom-like odor.

Airy, light and spongy, it forms lumps, due to the presence of vegetation. Fern, heather, moss, broom, horsetail, foxglove, nettle and buttercup grow spontaneously in this humus-rich, acidic soil.
