The topsoil is the upper layer of native soil found in any environment. It contains the highest amounts of micro-organisms and organic matter and is usually between two and eight inches in depth. However, the depth and the organic matter amounts can vary from place to place.
The topsoil layer is where most of the planet’s biological soil activity can be found. It is also in the topsoil where almost all plants grow their roots. This is why high-quality topsoil is of great importance to gardeners, agriculture and even the survival of the environment.
Topsoil is largely made up of four different elements, namely water, air, minerals and organic matter. The exact amounts of each varies according to the type of plants, moisture content and several other key environmental factors. This is why most gardeners check the type and consistency of their topsoil before planting.
Experienced gardeners will often buy bulk bags of topsoil that suit the types of plants they want to grow. This is because certain plants are more adept at surviving and thriving in certain types of soil. They also know it is important to understand the nature of topsoil when planning your garden.
There are three main constituents of topsoil found around the UK and wider world: clay, sand and silt. Clay is very rich in nutrients but doesn’t drain well and can cause all sorts of problems in wetter climates. On the other hand, sandy topsoil drains rather too well. It will usually need to be mixed with another kind of topsoil to retain enough water to grow plants. Silty topsoil tends to be very smooth and is made from quartz. Most soils are a mixture of all three constituents, with proportions of each one varying.
The most desirable topsoil for growing plants is loam, which combines about 30% clay with 70% either silt or sand. This provides a good mix of water and nutrient retention but also drains well enough not to damage the plants.
As well as being made of different constituents, soil can be acidic or alkaline depending on the conditions. This can be corrected by introducing new elements, depending on what plants you want to grow.
You can improve the quality and depth of soil by buying topsoil from a specialist for use in your garden. Here at Springbridge, we sell topsoil in various forms to help you improve your garden or growing space. Large bags of topsoil are available consisting of screened economy topsoil, multi-purpose blended soils and fine loam topsoil. Prices start from £64.99.
As well as topsoil bulk bags, we also stock smaller quantities and can arrange loose load deliveries.
After you buy topsoil to improve your growing space, you can consider adding mulches which have a number of benefits. Bark and other mulches protect all kinds of topsoils from extreme conditions. They help plants thrive even if there is too much heat or cold, as well as water excesses or shortages.
