Essential Soil Test Kit

This soil analysis indicates unbalances in your soil’s nutrients and pH.

Maintaining the pH and Nutrients of your soil is essential for the growth of your garden or lawn. This is commonly called a Soil Nutrient test or a Soil Fertility test.

You can add a metals test to ensure the metal in your soil isn’t at a toxic concentration. Also, our compost add-on tells you the organic content of your soil. This is vital for the decomposition process.

What it tests

This package is for the common factors affecting nutrients and soil growth.

pH Levels: Soil is rated on a pH scale, with a pH of 1 being most acidic and 14 being the most alkaline. Soil pH has in-direct yet an impactful effect on plants. Plant nutrients become available or unavailable according to the soil’s pH level. This test is known to indicate if there is a more serious problem in your soil. An unbalanced level of pH suggests the plant won’t get enough nutrients for growth. This unbalance can go as far as poisoning the plant. If the pH is too low, manganese can be present at toxic levels and if the pH is too high, the plant nutrient molybdenum becomes toxic.

Nutrients: Soil is a major source of plant growth. The three main nutrients associated with soil fertility are Nitrogen, Phosphorus, and Potassium. Nitrate is easily leached out of the soil by heavy rain, resulting in soil acidification. You need to apply nitrogen in small amounts so that plants use all of it, or in organic form, such as composted manure, so that leaching is reduced. Phosphorus transfers energy from sunlight to plants, stimulates early root and plant growth and hastens maturity. Potassium increases vigour and disease resistant of plants, helps form and move starches, sugars, and oils in plants, and can improve fruit quality. Knowing the nutrient unbalances in your soil allows you to take the right steps on correcting it.

You can add-on a metals test or a total organic compounds test, meant for determining the health of your compost.

Metals: Metals are a natural occurring substance inside our soils. The soil’s pH affects the availability of metals. Even though metals assist in soil growth, plants can have too much or too little of a certain metal. For instance, an iron deficiency, where there is yellowing in the veins of young leaves. Most plants thrive in slightly acidic soil because that pH gives them good access to all nutrients. Metals can become toxic to your vegetation as well. To See a list of metals tested, click here!

Total Organic Carbon: Organic matter is important in soil because it plays an important role in soil structure, nutrient availability, and water holding capacity. Knowing the organic content of your compost is essential for the decomposition process. If the Carbon-to-Nitrogen ratio is too high (excess carbon), decomposition slows down. If the Carbon-to-Nitrogen ratio is too low (excess nitrogen), you will end up with a stinky pile.

What you get

Upon purchase of this test, you will receive a CARO Kit:

Testing Containers – We fill your testing containers with the correct preservatives and store them at a specific temperature in our CARO Kit. For soil tests, you will receive jars instead of a vial-like container.

Sampling Guidelines – We’ll make sure you know the correct methods of sampling to ensure there aren’t any hiccups in the testing process.

Chain of Custody – This is a standard laboratory form that must be filled out and shipped back to us with the bottles. It’s used by our staff to make sure we do our job right!

The Report – We will send your report via email and you can access it online if you use our service called ClientConnect. Regulation maximum accepted concentrations are listed as well so you can compare your results.

Does not include sampling safety equipment as what is required depends on various circumstances. Please contact a local environmental consultant if you have questions or concerns about safely sampling. CARO provides testing services only, no sampling services.

How it works

After you purchase a kit on our store,

We will ship the CARO Kit to you via express shipping. In the CARO Kit, you’ll receive the sampling containers, a sheet to show you how to sample, as well as a chain of custody form (COC). The COC form is a standard lab procedure to get the correct information from you.

Once you sample, it’s advised to get the samples back to us ASAP. You can do this by getting that CARO Kit to a post office or courier and send it back to one of our locations. Certain tests like Microbiology (found in most drinkability packages) have a sample holding time of only 24 hours, so it’s vital to get the containers in transit right away.

So we’ve received your samples, allow 5 – 7 business days for us to analyze them and produce the reports for you. We will email the report to you when it’s ready. Every result’s turnaround time (TAT) will be started on the delivery of filled bottles back to the laboratory.

Internal rushes are possible for non-micobiology tests. Either use the Turnaround Time add on, or make a custom inquiry via the contact us webpage or on the phone.
