Soil Types!

6 Main Types Clay Silty Sandy Peaty Chalky Loamy

Clay Feels lumpy and sticky when very wet Rock-hard when dry Clay drains poorly Few air spaces Warms slowly in spring Heavy to cultivate If drainage is improved, plants grow well as it holds more nutrients than many other soils

Silty Soil Smooth and soapy to the touch Well-drained soil Retains moisture Richer in nutrients (more fertile) than sandy soil Easier to cultivate than clay Heavier than sand Soil structure is weak and easily compacted A very good soil if well managed

Sandy Soil Free-draining soil Gritty to the touch Warms up quickly in spring Easy to cultivate Dries out rapidly May lack nutrients, which are easily washed through the soil in wet weather (often called a "hungry" soil.)

Peaty Soil Contains a much higher proportion of organic matter (peat) because the soil’s acidic nature inhibits decomposition But this means there are few nutrients Dark in colour Warms up quickly in spring Highly water retentive and may require drainage if the water table is near the surface Fantastic for plant growth if fertiliser is added

Chalky Soil Alkaline, with a pH of 7.5 or more Usually stony Free draining Often overlays chalk or limestone bedrock This means some minerals, such as manganese (Mg) and iron (Fe), become unavailable to plants, causing poor growth and yellowing of leaves This can be remedied by adding fertilisers

Loamy The perfect soil Good structure Drains well Retains moisture Full of nutrients Easy to cultivate Warms up quickly in spring and doesn’t dry out in summer Consider yourself very lucky if you have this soil
