DIY Garden Soil Testing Procedure

Testing your soil at home in your own garden is not as difficult as you might think. Using a basic soil analysis unit, you can easily determine levels of potash, phosphorus, and nitrogen in the soil, as well as the pH level. This will help you determine conditions for growing plants and flowers in a garden. To conduct a test, there are a few simple steps that should be followed.


The first step is to dig a small hole about four inches deep into your garden. Be sure to wear gloves during this process, as you do not want to contaminate the soil by touching it with bare hands. It’s best to get a small amount of dirt from the hole about three inches away from the top of the sample. Next, you should break up any of the compacted soil to dry it and allow it to naturally separate, removing plant or stone material.

Acquiring Your Samples

Obtaining a few good soil samples for each type of element is important at this stage. You will need to fill each tube for pH, N, P, and K to ensure you receive accurate results for each unit. Try to use the required amount of soil and distilled water in perfect amounts to ensure best accuracy. Then, you should consult the scale that goes by a color-charted rating to figure out soil conditions. Once your analysis is complete, determining the results should be simple enough.

Reviewing Each Element

As you’ve taken levels of N, P, K, and pH, ensure that they are in accordance with proper levels for growing plants and flowers in your garden. Garden soil levels may differ slightly from lawn or other types of soil, so you should be sure to consult a guide — or read the one that comes with your soil testing kit to make sure you are in accordance with ideal growing conditions.

Liquid vs. Powder-Based Kits

Some kits provide a liquid test solution requiring you to add a small amount of powder to determine soil results. Powder-based kits also require powder, but then you’ll also need to add water to it in order to emulsify the soil. Then put the cap on your tube and make sure it is well shaken. Usually, most kits require 10 or so minutes to fully provide an accurate reading.

Final Steps

At this point, you should have a good idea of what conditions your flowers and plants are growing under where the soil is concerned. If you need to add more manure or compost to your soil to make it more acidic, when your pH levels are too low, you will easily be able to determine how much to add thanks to your garden soil test kit. However, if your soil tends to be too acidic already, it might be best to add more raw soil and back off on adding compost or other growing agents.
