Soil is a dynamic force in nature and comes in wide varieties that all serve different roles in the ecosystem. It has physical, chemical, and biological properties that work together to create what you see aboveground. Organic matter, gases, liquids, and countless organisms make up every form of soil. Everything from evergreen pines to fungi relies on soil to grow and thrive.
Understanding soil is key to knowing what’s best to grow in it. This starts with different classifications of soil, from sandy loam to clay. Determining which kind of soil you want will depend on what you’re planting.
Get to know your soil
Every kind of soil has specific minerals and acts as a habitat for organisms and has a certain pH level. This foundational material stores water and provides nutrient availability for plants to grow. The soil’s drainage determines what kind of plants can grow aboveground. There are a few terms that are important to know when it comes to soil:
- Silt: Loose sedimentary material that is carried by water with medium to high water-holding capacity and medium to high organic matter content
- Clay: Thick, heavy soil that is sticky when wet but hard when dry with high water-holding capacity and medium to high organic matter content
- Sand: Finely divided rock and mineral particles with low water-holding capacity and low organic matter content
- Loam: Contains close to equal proportions of sand, silt, and clay
Topsoil is the layer closest to the surface. Deep, rich, fertile topsoil can make the difference when it comes to planting flowers, trees, and bushes. Having the right mix of organic matter and minerals in your topsoil is critical for growing certain plants. That’s because topsoil provides nutrients that all plants need to survive. Loam is best for topsoil because it provides enough water retention while also being nutrient-rich.
Composting is a way to naturally enhance your soil, making it rich with nutrients and healthy for plants. This is form of organic recycling creates rich fertilizer that’s environmentally friendly while also being good for your garden.
