How to Identify Your Soil Type: 2 Easy DIY Tests
Soil Tests
When it comes to gardening, one of the most important factors to consider is the soil type.
Different plants thrive in various types of soil, so identifying your soil type can help you determine which plants will grow best in your garden.
There are various ways to identify your soil type, but two easy DIY tests can give you a good idea of what type of soil you have.
These tests are simple, and quick and require only basic materials that you probably already have at home.

The Feel Test
The 'feel test' is a simple, hands-on method that beginner gardeners can use to determine the type of soil in their garden.
This test involves using your senses, primarily touch, to assess the soil's texture and composition.
For this test, you will need:
Soil sample
Trowel to dig
Here's how to conduct the test:
1. Collecting Soil Sample
Start by digging 4 inches down into the area you want to test. It is important to test when the soil is damp but not overly wet. You can add water to dry soil or wait for a day after rainfall to ensure the right moisture level.
Once you reach the depth, take a small handful of this moist soil.
2. Performing the Feel Test
Roll the soil between your fingers and try to form it into a ball. Pay attention to how it feels and how it behaves in your hand.
Does it feel smooth, sandy, gritty, or silty? Does the ball hold together, or does it crumble apart?
Based on your observations, you can identify your soil type.
3. Identifying Soil Types
Sandy Soil: If the soil feels gritty and falls apart as soon as you open your hand, it's likely sandy soil.
Sandy soil won't hold its shape and will crumble easily. It won't form a ball when you press it between your fingers.
Clay Soil: If the soil feels sticky and can be easily shaped into a ball or a ribbon when pressed between your fingers, it indicates clay soil.
Clay will hold its shape and can be rolled into a thin, long ribbon. If the ribbon extends beyond 2 inches before breaking, it's a strong indication of high clay content.
Silt Soil: Silt feels smooth, like flour or wet cake mix, but not sticky like clay.
When you try to form a ball, it holds its shape better than sandy soil but will still break apart more easily than clay. It won't form a ribbon like clay but will feel slick when wet.
Loam Soil: This soil feels smooth, moist, and slightly gritty (due to the sand content), indicating a balanced mix of sand, silt, and clay.
It forms a ball that holds together but crumbles under slight pressure, showing good balance. It may form a short ribbon but breaks apart more easily than pure clay.
The Jar Test
The Jar Test is another easy and effective way to identify your soil type.
This method involves separating the different soil particles by size using a jar and water.
For this test, you will need:
Trowel to dig
A clear jar with a lid
Distilled water
Soil Sample
Liquid Dish Soap
Here's how to conduct the test:
1. Collecting Soil Sample
Start by digging 4 inches down into the area you want to test, just like in the feel test. Collect about a 1/4 cup of soil.
2. Preparing the Jar
Fill the jar with your soil sample and remove any visible debris such as rocks or roots.
Fill the jar with distilled water, leaving about an inch of space at the top, add a few drops of liquid dish soap, and tightly close the lid.
3. Shaking and Waiting
Shake the jar vigorously for 1-2 minutes until all the soil particles are suspended in the water.
Wait for 24 hours, giving ample time for the particles to settle. Be sure to place the jar in a location where it will remain undisturbed.
4. Identifying Soil Types
After 24 hours, you will see layers settling at the bottom of your jar. The larger and heavier particles like sand will be at the bottom, followed by silt and clay. Organic matter will float on top.
Use a ruler to measure the layers' thickness, and based on their ratios, you can identify your soil type.
5. Analyzing the results
Sandy Soil: If more than half of the composition is made up of sand, then the soil can be classified as sandy soil.
Silt Soil: If more than half of the total composition consists of silt with minimal clay content, then it can be classified as silt soil.
Clay Soil: If one-fourth of the total composition consists of clay, along with a substantial amount of silt, it indicates the presence of clay soil.
Loam Soil: If you find yourself with a composition of 2/5 sand, 2/5 silt, and a thin layer of clay, congratulations! You have struck gold with a splendid loamy soil.
Identifying your soil type is crucial for any gardener, and you can do it easily by performing simple soil tests.
The feel test and the jar test can help you determine if your soil is sandy, loamy, or clay soil, and this knowledge will guide you in choosing the right plants and amendments for your garden.
Remember that soil type can change with the location and depth, so it's recommended to test soil in different areas of your property.
