There are a vast number of soil amendments, and I won’t go into all of them here. I’ve written previous blog entries about some of them and will link them below! One of the most important ones, though, is organic matter like compost, dry leaves, old mulch, and other materials like that. Tilling these kinds of materials into the soil provides a whole new kind of food to the plants and other creatures that live in the soil. It attracts earthworms, which open airways in the soil and leave behind castings, which are nutrient rich “worm droppings” – you can actually buy bags of those droppings from us, by the way – and other beneficial burrowing critters.
