The first rule if you want to improve garden soil is that there is no such thing as bad soil. If the options you are thinking about are either improve garden soil or buy top soil then don't waste your money buying so-called "good top soil". Doing this will only import someone else's problems. In all cases, the improvement option is by far the best.
What you need is a simple and reliable method of making good top soil from whatever is available. Such a system would be one that worked equally well on any garden soil, anywhere in the World.
The first such method to be developed was the Albrecht system and, with just a few refinements from more recent research, it still works well today.
However, Let's begin with a brief description of what soil is and what it does in the garden.
We have a page here that describes this in detail.
The link to that page opens a new window, so you can read through it and then come back here.
Another concept to clarify is Balance. These days everything seems to be balanced, from Dog Food to Hair Shampoo, but nobody ever seems to really say what that means.
What we need is a good description of what soil balance really is.
This will lead us to the question of how soil balancing actually works. It can seem a bit strange, but the balance of just a few important elements has a profound impact on the structure and friability of the soil. Where people get confused is that these elements (Calcium, Magnesium, Potassium and Sodium) are also plant nutrients. the trick is to remember that once you have the balance right, there should be more than enough of these in the soil to meet the needs of any plant.
Having followed these steps to improve garden soil, you now have to maintain its health and condition. In addition to the monitoring and fine tuning above, there are also a few other strategies you can use to keep your soil healthy and productive.
Clearly there is a lot to consider before trying to improve garden soil and there are even more links below for still further reading. Additional information will be added as it becomes available, but you can easily keep in touch by subscribing to our Free email newsletter - The Food Gardener.
What is soil and how does it work? As a medium for plant growth, soil must provide anchorage, nutrients, air, water and biological interactions if healthy plant growth is to be achieved.
