Which Soil is Best for Drainage?
To the untrained eye, soil is just soil. It sits in the garden, under grass and around plants, taking in nutrients and helping vegetation thrive. However, there are actually many different types of soil, and each one offers different drainage qualities that are suitable for different purposes.
For the best possible drainage performance, it is difficult to look beyond sandy soil. The reason being that the particles of soil are the largest out of any soil type, which means the pores are also the largest. Large pores allow for more water to pass through the spaces, which means the soil drains much quicker. A simple way to test the drainage capacity of your soil is to pour some water on it – if you soon notice that the soil appears dry again, that means that the large pores are making for excellent drainage.
Loamy soil has a mixture of particle sizes, which means that although it still has good drainage properties, it does not drain as quickly as its aforementioned sandy counterpart. It retains moisture well, which means that any moisture is contained near the surface, making it easier for roots to access it. It does not retain water to the extreme, however, which means that there is no risk of plants being denied access to air.
Silty soil has good retention qualities, but despite its relative fertility, it does not retain nutrients as well as it might. The moisture-retentive quality of the soil means that it does not drain well, and if it is not looked after properly, it can become poorly aerated and compacted.
- Dark – This means that the soil contains a high amount of organic matter. This type of soil is preferable for garden plants, as they benefit more from a higher concentration of organic material.
- Brown-red – This is a sign of adequate aeration and drainage properties.
- Blue-green/grey – This is a symptom of overly wet soil, or soil that is continuously saturated. Not good for garden plants.
- Yellow – A yellow colouring to the soil is often a sign of poor drainage.
- Mottling/streaking – This is a symptom of seasonal drainage issues.
It is important that you have the right soil for your site. If you want soil that helps you grow plants and vegetation, or you want soil to place under paving, make sure that you are aware of the benefits of different soil types before you make your purchase.
