Soil Amendments, all you need to know.
Organic matter is the very heart and soul of organic gardening.
Organic matter is the waste residues and remains of living organisms. As it undergoes the natural process of decay in the soil, it is converted gradually to a very stable form called humus. There are few things as important to garden preparation as adding organic matter to the soil. Ultimately, humus and the process by which it is formed can have a dramatic impact on your garden. Synthetic fertilizers cannot replace organic matter lost through soil mismanagement.
