There are many ways to improve topsoil and ensure that its health is assured, but whichever method is chosen, this will depend on the topsoil’s quality in the first place.
Understanding how topsoil is composed and what goes on inside it is a very useful way for gardeners to be able to improve their soil. The balance of topsoil is a great way to learn about the chemical and physical properties of topsoil. This also means that topsoil chemistry and physics as well as biology are learnt about further ensuring that nutrients and structure are perfectly balanced.
One system that ensures topsoil balance is correct is known as the Mikhail system. This system of topsoil balancing focuses firstly on the soil’s structure which enables good friability and topsoil composition so that living organisms can flourish. Topsoil needs a skeleton to enable the other elements of its make-up to exist and be sustained, rather like the human body. Potassium, Hydrogen, Magnesium, Sodium and Calcium are all essential elements in good healthy Topsoil.
The Mikhail system then helps to ensure that the nutrients and biology of the topsoil is in order. Balancing the structure is then important. Essential elements for plant nutrition are Phosphorous, Potassium, Nitrogen and Sulphur. Once the topsoil’s structure has significantly improved and balance corrected, then fertiliser can be added to maintain the correct levels of these elements. The most common fertiliser is known as NPK, and most general fertilisers actually consist of these chemical elements. A topsoil’s trace element content is particularly important.
Performing tests on topsoil will enable the missing components of the soil to be amended as required. Using soil testing apparatus is the perfect way to test the soil and get the necessary information for making improvements. The required fertiliser, lime and other soil improving material can then be obtained to ensure that the topsoil performs better.
