Soil health and soil testing


Materials needed for testing pH level from your kitchen: baking soda, vinegar and distilled water.

Imagine you’ve been busy working all day and haven’t had a chance to eat. When you finally get to the door of your favorite restaurant, you pull the handle only to find that the door is locked. Through the window you can see the staff busily preparing food, but try as you might, you are unable to get anyone’s attention. It’s easy to imagine how frustrated you’d be.

Surprisingly, your garden may be facing this same desperate situation. If the pH level in your soil is either too high (alkaline) or too low (acidic), then the nutrients that your garden desperately need could be present in the soil but unable to be absorbed by the plant’s root system. Getting your soil’s pH right is the key, so to speak, to the restaurant’s door.

What is the secret to raising healthy vegetables and flowers? Great soil. How can you tell if your soil has what plants need? A soil test.


The good news is you don’t have to take your soil samples to any agricultural extension services lab or even using a soil kit to get vital information of type of soil and how best it can be to help make your plants thrive. For instance why do you need to know the pH level of your soil? Why do you need to know if your soil is alkaline or acidic? Knowing your soil pH is the key to understanding if essiential mineral and nutrients will be available to the roots of your plants. There are simple do-it-yourself soil tests you can do that can determine what you need to do to help you soil and improve your gardening results. Learning as much as you can about your soil will help you decide what needs to be done to make it ideal for the plants you want to grow. If you can learn about your soil’s texture, composition, drainage, acidity, and mineral density, you will avoid, up front, the disappointing results that can occur when your soil is unsuitable for your dream garden.

Soil Test 1: The Squeeze Test
One of the most basic characteristics of soil is its composition. In general, soils are classified as clay soils, sandy soils, or loamy soils. Clay is nutrient-rich, but slow draining. Sand is quick draining but has trouble retaining nutrients and moisture. Loam is generally considered to be ideal soil because it retains moisture and nutrients but doesn’t stay soggy.

To determine your soil type, take a handful of moist (but not wet) soil from your garden, and give it a firm squeeze. Then, open your hand. One of three things will happen:
It will hold its shape, and when you give it a light poke, it crumbles. Lucky you—this means you have luxurious loam!
It will hold its shape, and, when poked, sits stubbornly in your hand. This means you have clay soil.
It will fall apart as soon as you open your hand. This means you have sandy soil.
Now that you know what type of soil you have, you can work on improving it.

Soil Test 2: The Percolation Test
It is also important to determine whether you have drainage problems or not. Some plants, such as certain culinary herbs, will eventually die if their roots stay too wet. To test your soil’s drainage:
Dig a hole about six inches wide and one foot deep.
Fill the hole with water and let it drain completely.
Fill it with water again.
Keep track of how long it takes for the water to drain.

If the water takes more than four hours to drain, you have poor drainage. Soil Test 3: The Worm Test
Worms are great indicators of the overall health of your soil, especially in terms of biological activity.

If you have earthworms, chances are that you also have all of the beneficial microbes and bacteria that make for healthy soil and strong plants. To do the worm test:

Be sure the soil has warmed to at least 55 degrees, and that it is at least somewhat moist, but not soaking wet.Dig a hole one foot across and one foot deep. Place the soil on a tarp or piece of cardboard.

Sift through the soil with your hands as you place it back into the hole, counting the earthworm as you go. If you find at least ten worms, your soil is in pretty good shape. Less than that indicates that there may not be enough organic matter in your soil to support a healthy worm population, or that your soil is too acidic or alkaline.

Soil Test 4: Ph Test
The Ph (acidity level) of your soil has a lot to do with how well your plants grow. Ph is tested on a scale of zero to 14, with zero being very acidic and 14 being very alkaline. Most plants grow best in soil with a fairly neutral Ph, between six and seven. When the Ph level is lower than five or higher than eight, plants just won’t grow as well as they should.

The Pantry pH Test for Soil Acidity or Alkalinity
Place 2 tablespoon of soil in a bowl add ½ cup vinegar. If the mixture fizzes, you have alkaline soil.
Place 2 tablespoon of soil in a bowl and moisten with distilled water. Add ½ cup baking soda. If mixture fizzes you have acidic soil.
These tests are simple, inexpensive ways to ensure that your garden has the best foundation possible.
