If you want to grow plants effectively, one of the most fundamental things you can do is provide them with soil which is appropriate for the species and which provides a rich and balanced amount of nutrients. The ideal of creating a permaculture system such as a food forest is that the soil will be balanced and nourished naturally by the diverse amount of species living there, with humans having only to input minimal effort by occasionally adding mulch or chopping plants to provide more organic material. But until you get to the point where you have a self-mineralising food forest, what is the best way of adding minerals to the soil? What do we need to be amending the soil with and how does this help? This article will explore some theories and methods of soil mineralisation and how they can be effective.
