Examples of soil types

Loam soil is a mixture of sand, silt and clay that are combined to avoid the negative effects of each type.

These soils are fertile, easy to work with and provide good drainage. Depending on their predominant composition they can be either sandy or clay loam.

As the soils are a perfect balance of soil particles, they are considered to be a gardeners best friend, but still benefit from topping up with additional organic matter.

Chalk soil can be either light or heavy but always highly alkaline due to the calcium carbonate (lime) within its structure.

As these soils are alkaline they will not support the growth of ericaceous plants that require acidic soils to grow.

If a chalky soil shows signs of visible white lumps then they can’t be acidified and gardeners should be resigned to only choose plants that prefer an alkaline soil.

Peat soil is high in organic matter and retains a large amount of moisture.

This type of soil is very rarely found in a garden and often imported into a garden to provide an optimum soil base for planting.

Silt Soil is a light and moisture retentive soil type with a high fertility rating.

As silt soils compromise of medium sized particles they are well drained and hold moisture well.

As the particles are fine, they can be easily compacted and are prone to washing away with rain.

By adding organic matter, the silt particles can be bound into more stable clumps.

Clay Soil is a heavy soil type that benefits from high nutrients. Clay soils remain wet and cold in winter and dry out in summer.

These soils are made of over 25 percent clay, and because of the spaces found between clay particles, clay soils hold a high amount of water.

Because these soils drain slowly and take longer to warm up in summer, combined with drying out and cracking in summer, they can often test gardeners.
