Garden soil testing is an important, but oft overlooked task by beginners. I have sex it sounds ungovernable, simply it's actually actually easy, and tuppeny too! And so, in this post, I will show you exactly how to prove your soil using a home examination kit, step away ill-use.
I have it off that testing your soil sounds like IT would be complicated, time consuming, Beaver State even high-priced, but it's not. So, to still your nerves, I am going to walk you through and through it step away step.
There's no deman to send your soil sample off to some company, or pay for some expensive testing. Victimization a DIY home soil test kit is frugal, simple, and gives you very dissipated results.
Once you know what nutrients are deficient in your soil, you have got the information you need to properly amend it, and grow your best garden one of these days!
Here's what you'll obtain in that stone's throw-by-measure draw for how to use a soil test kit out…
Why Should A Householder Perform Soil Testing?
All plants need nutrient rich, fertile soil to grow their best, stay healthy, and produce scores of flowers and vegetables for us to enjoy.
But it's impossible to narrate if your garden soil is healthy retributive by look at it, you stimulate to quiz it to know for sure. Using a domicile soil test kit is easy, and will quickly tell you if in that respect are any nutrient imbalances.
When To Do A DIY Soil Test
It's a good idea to test your territory at the end of every gardening season, so that you can add amendments ahead planting again.
Then you can test the dirt again in the resile to check if the health has improved, and add any additional amendments that it may need.
Home soil testing is easy
How To Test Soil For Nutrients
Your soil test kit should come with instructions for use. So make reliable you review those first, because they might make up somewhat different than my steps below.
My kit came with four different containers for testing each of the main nutrients. Pink for nitrogen (N), blue for atomic number 15 (P), orange for potassium (aka: potash) (K), and greenish for pH.
To boot to your kit, you'll need a fewer unusual supplies before you get started.
Soil Testing Equipment Needed:
- Land trial run kit
- Clean container (I used a kitchen bowl)
- Clean garden trowel operating room large spoon
- Distilled water supply
- Measurement transfuse (1 cup)

How To Accumulate Soil Samples For Examination
The early step for all four of the tests is to assume a soil try. Pickings the try is really easy, merely you'll want to make sure that your tools are clean first.
Usage a uninfected trowel to take your garden soil sample (don't use your hands), and also catch up a clean container or large arena to put information technology in.
If you don't have a trowel that's promiscuous to launder, then you hind end just utilize a large spoon from the kitchen.
Remove any mulch or debris from the pinnacle of a small country of your soil, then dig down about 3-6 inches to accept your sample (the garden bed I'm testing is parvenu, so there International Relations and Security Network't any mulch along top nevertheless).
In ordinate to bash all quatern tests, you'll need a little more than one cup of soil (one transfuse for the N-P-K tests, and less than one teaspoon for the pH).
Taking the soil sample for testing
How To Try Your Soil At Home Step-By-Step
The operating instructions are selfsame for testing the N-P-K values, simply slightly different for the pH. So, below I'll break down the steps for both types of tests.
I'll start with the pink, blue, and orange N-P-K soil test kit, sol set your green pH container aside for right away.
Testing Phosphorus, Caustic potash, &ere; Nitrogen (N-P-K)
Before jumping into the steps for testing the N-P-K levels, I wanted to give you a heads up that IT takes a little thirster to check these values than it does for the pH story.
That's because, for these tests, you motivation to mix your soil sample with water, and let information technology sit until everything settles (which can take up to 24 hours).
Indeed just keep that in idea when you design to do your examination, to make sure you give yourself plenty of time.
Follow the steps below to usage the phosphorus (blue), potash/potassium (orangeness) and nitrogen (pink) test kits.
Phosphorous, potash, and nitrogen test kits
Footfall 1 – Mix your soil sample with water: In a clean bowl, intermixture indefinite cup of your soil sample with five cups of distilled water.
It's authoritative to use distilled water rather than beg water to ensure your test results are accurate (tap water contains chemicals and minerals that can skew the results).
Preparing garden soil try out for testing
Tread 2 – Allow the soil to settle: Stir or shake your soil/water mixture for a minute surgery indeed, and past Lashkar-e-Tayyiba it sit until everything settles.
Remember, you mightiness have to wait a while to go on to step 3. Also, information technology testament take practically longer for stiff soils to settle than for beachy ones (impenetrable clay stool adopt to 24 hours to settle).
You want the testing water to be as legible as achievable, so it's bettor to give it enough time to settle than to rush this step. To make it easy, I just let my soil sample settle overnight (I have sandy soil).
Getting ready to test my soil
Footmark 3 – Fill test kit containers with sample water: Now that everything has settled, urinate confident you don't go out the soil sample/water mix, operating room disturb the muck at the bottom. You'll exclusive be exploitation the water for these tests.
Fill both chambers of the N-P-K testing containers with your sample water capable the line towards the acme. Your kit should come with a little dropper to make it super easy.
Filling soil test kit out reference chamber with water solution
Don't fill out them all the way to the top of the container though, you'll need a little snatch of headspace to shake them dormie later on you bring the test powder in ill-use 4.
Merely you do want the water level to be above the top of the colored boxes (it's really hard to see, but there is a real ill dotted line at the top of remaining chamber to indicate the water level).
Fill reference chamber to the line
Step 4 – Add the test powder: Everything that comes with your type of soil test kit will probably be color coordinated like mine is.
There are colored capsules that come with the kit, and these contain the testing powders for each nourishing.
The color of capsule you need to use for each test matches the color of the lid for that container (i.e.: violet lid/capsule for nitrogen (N), blue lid/capsule for Lucifer (P), and Orange River for potassium).
I recommend doing this close part in an region where at that place's no wind. You don't want to inhale the powder, or get any of it in your eyes OR mouth off.
Carefully pull apart the capsule so that you can teem the powder into the left bedchamber of your tryout kit. You should merely put the powderise in there, not the intact ejector seat.
Don't countenance any of the powder put on the water in the right side compartment (that needs to just be the clear mental testing H2O).
Add powder from capsule to the quiz water
Stride 5 – Give up the test powder to break up: Put the pileus back along the container, devising for certain it's on there close so the irrigate doesn't get mixed between the ii compartments.
Past shake the container until the powder is dissolved in the quiz water. You may notice it dynamical colorise right away, or you mightiness non watch any change the least bit. So, let the N-P-K tests sit for 10 minutes before you say the results.
Examination Soil pH Levels
The soil pH tester is a bit different than the N-P-K ones, and IT's a lot faster. You'll need to a lesser degree a teaspoon of sample bemire to perform this mental test.
But make water sure you follow the same stairs for how to takings soil samples above to pull together it (using clean tools, not your hands, etc.).
If your kit didn't accompany a pH scale tester, don't worry. You can buy a garden soil pH examination kit, Beaver State get a pH soil probe to check it.
Follow the steps below if you'rhenium using a DIY home kit to test the pH of garden soil.
Testing the pH of garden soil
Step 1 – Put your soil sample into the test container: Tally a small amount of your soil sample to the left side chamber to fulfil it to the line (it's really just a tiny bit).
I tried using the dropper thingy for this, but that does not work, so don't do that. I found it easier to use a moderate spoon to get the dirt in there.
You don't have to Be too fussy or worry about getting ungraded into the right side compartment. And if you accidentally fill information technology above the bloodline, then you can just spill out the extra. None biggy.
Filling pH measuring outfit with soil sample
Step 2 – Total the test powder: Snaffle one of the jet capsules for this test (operating room the one that came with the kit you get).
Once more, I advocate doing this part in a smudge where there's no scent. You put on't desire the pulverise blowing away, or getting into your eyes Beaver State mouth.
Put only when the powder into the water, not the intact capsule. So, carefully separate the two sides of the capsule, and pour the powder into the left bedroom (reactionary happening tipto of your soil taste).
Step 3 – Add distilled water: Fill out the rest of the left side compartment with distilled pee adequate the fill index number arrow (this is where you can use the dropper thingy). Leave the right side of the container empty for this test.
It's best to use distilled water for your pH test, in case there are chemicals in your knock water that will skew the results.

Step 4 – Mix everything together: Put the covert back on your pH essa, and snap IT on tight.
Now you can shake the heck out of it to mix the soil and test powder with the water. Let everything settle for some one minute before reading the pH scale test results.
How Long Does It Take To Get Soil Test Results
The thing I like the well-nig about doing my possess testing at home with a DIY kit is that it's real fast (and easy!). The preparedness steps are what take the most time.
One time you've added everything into the chamber, the pH test gives you results in about one minute. Since you don't have to worry almost soppy your stain sample beforehand, total time for this one is only about 10 minutes.
The N-P-K testing takes a fleck longer, since it's a bit more than of a process to prepare your test sample. Once the containers are full, it lonesome takes about 10 transactions ahead you nates analyze the results.
But, plan for the summate time of the N-P-K testing to take somewhere between 12-24 hours, conditional how long IT takes you soil sample to settle in the piddle (heavy clay soils will take thirster than sandy ones).
Analyzing Your Soil Test Results
To analyze your results, hold each one up to a source of natural light (non direct sunshine though). Then just compare the color of the H2O on the left side with the color chart on the right.
It's pretty easy to get a line if your grunge is severely deficient in one or more than of the N-P-K nutrients, because there will hardly be any color in the left side.
Basically, the darker the color is in the left compartment, the Sir Thomas More of the specific nutrient your soil contains.
Nitrogen ground testing results
You sack see from my N-P-K tests (photo below) that my soil is insufficient in nitrogen (pink), sufficient in caustic potash (orange), and has a surplus of phosphorus (blue).
Same estimation for the pH soil analysis. Compare the color of your sample on the left to the chart connected the right. The color graph volition picture you how acidic or alkaline your soil is.
You can see from the results of my pH test (the green one on the right), that my soil is alkaline.
Analyzing soil test results
Testing your soil is extremely helpful for growers of any level. Once you lie with the N-P-K and pH levels, you're armed with the information that you need to properly amend your soil. No more more guess, now you know exactly what amendments to add together to grow your best garden ever!
