What Is Soil and Why Does Soil Health Matter?
Understanding soil is the first step to a thriving garden. Soil is an ecosystem that’s important for plant health. Mastering the basics of soil will help you in keeping your plants healthy and supported.
Layers of Soil
Soil is composed of several materials that are necessary for sustaining living organisms and plants. It contains air, water, rock particles, and several organic matter. It is also home to fungi, earthworms, and other microorganisms that contribute to soil health. Each layer of soil has an important role to play.
Here are the different layers of soil:
- Topsoil – Topsoil typically has less clay but more organic material and air compared to the layers below. This makes it super fertile and home to most roots.
- Subsoil – The subsoil tends to be heavier on the clay and lighter on organic matter when compared to the topsoil. You’ll often spot shades of red, brown, and yellow in it. When the soil doesn’t drain well, the subsoil might look more on the gray side.
- Rock Layer – This layer is found at the bottom part and provides stability.
These layers affect how well plants can grab the nutrients and handle the soil’s pH. It directly impacts their growth and well-being.
Soil Health
Healthy soil is your garden’s best friend when it comes to plant growth and vitality. It’s a vibrant community of life that provides essential nourishment for your garden.
Soil plays an important role in mitigating climate change by trapping carbon from the atmosphere. Its pH and texture also influence your plant’s nutrient absorption ability as most plants thrive in soil with a pH between 6.5 and 7. Now you can already see how poor soil can affect plant life and its way of survival.
What Are the Different Types of Soil?
Soil varies in texture and composition, which can affect the type of plants you can grow in it. Successful gardening means being able to identify your soil type and adjusting it to fit your preferences in plants.
1. Clay Soil – Rich, Heavy, and Packed With Nutrients
Clay soil is packed with nutrients and retains water well but it can be difficult to work with. This type of soil has poor drainage due to its tiny particles. Clay is ideal for plants that like moist conditions. When wet, it can be very compact and leave little room for aeration. When dry, it can get rock-hard.
Plants that thrive in clay soil:
- Roses
- Bluebells
- Foxglove
2. Sandy Soil – Loose, Light, and Easy to Work With
Sandy soil drains quickly. It’s easy to work with but doesn’t hold nutrients well. This makes it the perfect medium for plants that prefer drier conditions. Sandy soil has large, quick-draining particles that warm up rapidly.
Plants that thrive in sandy soil:
- Tulips
- Daphne
- Hibiscus
3. Silt Soil – Medium-Sized With Good Water Retention
Silt soil is rich in nutrients and retains water well but it can compact easily. This will result in reduced air space for plant roots. Silt is formed by water depositing fine particles of rock and dirt.
Plants that thrive in silty soil:
- Mahonia
- Phormium
- Kerria
4. Loam Soil – Ideal Gardening Soil
Loamy soil is a balanced mix of organic matter, sand, silt, and clay. Most plants thrive in loamy soil because it drains well, is nutrient-rich, and easy to work with. The combination of materials found in this type of soil makes it perfect for growing a wide variety of plants.
5. Peat Soil – Acidic Soil Packed With Organic Matter
Peat soil is acidic and full of organic matter. It retains water well but may need pH adjustment for plants that prefer neutral conditions.
Plants that thrive in peat soil:
- Heather
- Crinodendron
- Camellia
6. Chalky Soil – Alkaline and Stony With Good Drainage
Chalky soil is alkaline (pH above 7) and drains well due to its stony nature. It is quite hard to work with because of the large pieces of chalk and flint present.
Plants that thrive in alkaline soils:
- Mint
- Lilac
- Dianthus
Choosing the right plants for your soil type means you spend less time and money on extra care. Plants that suit your soil type are already set up to soak up the nutrients and water they need. Make it a habit to start with plants that love your soil.
How Do You Identify Your Soil Type?
Soil texture affects how water drains, what nutrients are available, and how roots grow. We’ll walk you through easy tests to determine if you have sandy, clay, or loamy soil. This info will be handy for planning your garden.
How to Test Soil Texture
Every patch of soil has its unique characteristics, which affect the plants that can thrive there. You can identify your soil’s texture using the following tests:
- Feel Test – Take a bit of soil, moisten it, and feel its texture. Is it gritty, smooth, or sticky? This gives you a clue about the sand, silt, and clay in your soil.
- Jar Test – Fill a jar with soil and water, shake it, and watch the layers settle to reveal the proportions of sand, silt, and clay present.
How to Test Soil pH
Soil pH is key in gardening because it tells you if your soil is acidic, neutral, or alkaline. This matters because the pH of your soil affects how well plants can use the nutrients in it.
Testing your soil’s pH is easy. You can use a kit at home or send samples to pros. Here’s how:
- Collect soil samples from different spots in your garden.
- Follow the kit’s instructions.
- Check the results. The pH scale goes from 0 to 14. 7 is neutral. Below 7 is acidic, and above 7 is alkaline.
Knowing your soil’s pH helps you pick the right plants and the right food for them. Acid-loving plants like rhododendrons and azaleas are happy with a pH below 7. Alkaline-loving plants like lavender and geraniums do best in soils with a pH above 7.
How Do You Prepare and Amend Your Soil for Gardening?
Preparing your soil means getting the structure, nutrient levels, and pH balance just right. Listed below are the basics of soil preparation and some tips on how you can improve it.
Here’s how you can prepare and amend your soil:
- Know Your Soil – Know what you’re working with before you start adding anything. Different soils have different needs. A quick soil test will tell you if your soil is more on the acidic side, alkaline side, or just right. Most plants like a pH that’s not too high and not too low.
- Add in Organic Matter – Once you know your soil, it’s time to add some organic matter to your garden bed. This can come in the form of compost, old leaves, or even certain types of manure. Add this to the top 5-10 inches of your soil to improve water retention, and soil texture, and boost nutrient availability.
- Determine How Much to Add – Aim for about half a wheelbarrow of amendments for every square meter. This ensures your soil stays rich and fertile.
- Use the Power of Mulch – Mulch is an excellent ground cover. It can come in the form of hardwood, wood chips, and old leaves. Mulch decomposes and feeds your soil as it breaks down. It also prevents soil erosion and helps with water and temperature control.
- Do Double-Digging – This can also be an option when you want to improve soil aeration and drainage. Taking good care of your soil leads to healthy plants and a bountiful harvest.
- Use Fertilizers – There are two main types of fertilizers: organic and synthetic. Organic fertilizers come from once-living things and are rich in organic matter. Synthetic fertilizers are man-made and offer a quick nutrient boost. Fertilizers are often packed with essential elements such as nitrogen, phosphorus, and potassium.
