OTHER TYPES OF SOIL

CHALK SOIL - are highly variable and range from gravelly to clay-like. The clay-like element may in fact be finely divided calcium carbonate making it very poor for plant growth. However where true clay is present in the soil, nutrient levels may be higher and the water holding capacity greater. Chalky or lime-rich soil may be light or heavy but are largely made up of calcium carbonate and are very alkaline (they have a pH of 7.1-8.0). Very chalky soils may contain lumps of visible chalky white stones. Chalk soil is not suitable for elegantly coloured flowers such as rhododendrons but several varieties of bushes, lilacs and lilies will flourish.

PEATY SOIL – is a mixture of decomposed plant material which has accumulated in a water-saturated environment in the absence of oxygen, it is usually dark brown but it can also be black. The soil has a lot of organic material and is rich in water, which makes it one of the best types of soils for plants. Because of a high water and nutrient content, peaty soil keeps plants healthy even in dry weather and protects the plants from harm in rainy months. The water content of peaty soil is a little acidic but is good for controlling plant diseases and can be used to balance the pH level of other kinds of soils.

SALINE SOIL – is usually brackish because of its high salt content, it can stall plant growth, hinder germination, and cause difficulties in irrigation. The salinity is due to the accumulation of soluble salts therefore preventing water uptake by plants, resulting in drought stress. It’s easy enough to test for saline soil, there will be a white layer coating the surface of the soil, plants will be growing poorly and suffering from leaf tip burn, especially on young leaves.

Knowing where you stand with your soil helps you determine what fertilizers and amendments you need to add before you get started.
