In this post , I ’ll take the air you through the entire process footstep - by - measure . Once you know what your filth is lack , you could add the right amendment to give your garden the well potential start .

Why Testing Your Garden Soil Matters
All plant necessitate nutrient - fertile , fecund dirt to produce their best , stay good for you , and produce tons of flowers and vegetables for you to enjoy .
But here ’s the matter – it ’s impossible to tell if your garden soil is healthy just by wait at it . You have to test it to know for sure .
A quick DIY test will show you exactly what your soil has too much of and what it ’s missing , so you could add the right amendment to fasten it .
When to Test Your Garden Soil
The expert clock time to test your soil is in the fall , at the goal of the horticulture time of year . That way , you ’ll have plenty of time to append any amendments before springiness rolls around .
you’re able to also screen it in early fountain to see if the grunge has improved or if it needs a little extra help before planting .
How Long Does an At-Home Soil Test Take?
The meter it takes to get your results reckon on the eccentric of test you ’re doing . But either manner , it ’s the prep work that withdraw the long . Here ’s a breakdown of what you’re able to await :
Everything You Need for a Simple Soil Test
Your stain test kit should fall with instructions for use . So check that you retrospect those first , because they might be slenderly dissimilar than my steps below .
My outfit came with four different color - dupe containers for testing each of the master nutrients . Pink for atomic number 7 ( N ) , blue for Lucifer ( phosphorus ) , orangish for potassium ( aka : potassium hydroxide ) ( K ) , and green for pH.
In addition to your kit , you ’ll need a few other supply before you get started :
How to Take a Soil Sample
The first whole step for all four of the tryout is to take a soil sampling . Taking the sampling is really gentle , but check that your tools are clear first .
employ agarden trowelor big spoon ( do n’t use your hands ) , and also seize alarge bowlor other container to put it in .
slay any mulch or debris from the top of a small area of the soil , then dig down about 3 - 6 inches to take your sample ( the garden seam in the photo below is young , so there is n’t any mulch on top yet ) .
If you need to do all four tests in the kit , you ’ll need a little more than one cup of filth ( one cup for the N - atomic number 15 - K tests , and less than one teaspoon for the pH ) .
How to Test Your Soil at Home (Step-By-Step)
The appendage for test each of the 3 main land nutrients ( N - P - K ) is pretty much the same , while the pH stone’s throw are more or less dissimilar – so I ’ll walk you through each .
I ’ll get going with the pinkish , downhearted , and orange containers , so set your green pH test aside for now .
1. Testing Soil Nutrients (N-P-K)
Before jumping into the steps for testing the N - P - K , I wanted to give you a caput up that it select a niggling longer to check these values than it does for the pH level .
That ’s because the soil needs to settle down in water ( sometimes overnight ) . So keep that in mind so you could plan accordingly . Ok , now on to the steps .
stair 1 – Mix your grease sample with water supply : In a clean bowl , mix one cup of your land sample with five cups of distilled water supply .
It ’s important to habituate distill body of water rather than bug water to ensure your test results are accurate ( tap water check chemicals and minerals that can skew the results ) .
measure 2 – Let the dirt settle : Stir or judder your soil and water commixture for about a minute of arc , then lease it sit until everything adjudicate and the water sack up .
stiff soils can take up to 24 hours to amply settle , while arenaceous soils all the way faster . Do n’t rush this part – the unclouded the water , the more accurate your outcome . I normally lease mine ride overnight .
Step 3 – Fill the trial run container : Once everything has settled , make trusted you do n’t move the soil sampling / body of water commixture , or disturb the muck at the bottom . You ’ll only be using the water for these examination .
Fill both chamber of the N - atomic number 15 - K testing containers with your sample body of water up to the pedigree towards the top . Your outfit should make out with a picayune eye dropper to make it passing easy .
Do n’t fill the container all the means to the top though , you ’ll involve a little bit of headspace to shake them up after you lend the test pulverisation in step 4 .
But verify water level is above the colored boxes ( it ’s really heavy to see , but there is a very fainthearted dotted line at the top of left chamber to indicate the water spirit level ) .
Step 4 – Add the psychometric test powder : The capsules that come with the outfit are colour - coded to the respective containers . So snap up the one that equalize your test container .
I recommend doing this next part in an field where there ’s no idle words . Also , be measured not to inhale the powder or get any of it in your eyes or mouth .
Pull aside the capsule and pour the gunpowder ( not the intact capsule ) into theleft sleeping room only . Do n’t get any powder into the right side compartment , that water should stay clear for comparison .
Step 5 – Mix and wait : click the eyelid on tightly , then excite the container to dissolve the pulverization . The water may change colour right away or it may go on gradually . Either way , permit it sit for about 10 minutes before checking your results .
2. Testing Soil pH Levels
The pH test exploit a bit different from the N - phosphorus - K I , and it ’s much faster . You ’ll need less than a teaspoon of soil .
But ensure to follow the same method to take your sample distribution as I delineate above ( no deal , clean peter , etc . ) .
Step 1 – Put your territory sample into the trial container : Add a small amount of your sampling soil to theleft side chamberto fill it to the line of credit ( it ’s really just a midget bite ) .
I tried using the dropper thingy for this , but that does not work , so do n’t do that . I found it easier to expend a minuscule spoon to get the malicious gossip in there .
You do n’t have to be too crabby or occupy about acquire shite into the proper side compartment . And if you unintentionally fill it above the assembly line , then you’re able to just pour out the extra . No biggy .
Step 2 – lend the test pulverization : Grab a greenish capsule ( or whichever one came with your outfit ) and cautiously open it . Then pour out the gunpowder into the left-hand chamber , aright on top of your soil sampling .
Again , I commend doing this in a daub where there ’s no wind . You do n’t need the gunpowder blowing away , or getting into your eyes or mouthpiece .
footstep 3 – Add distilled water system : occupy the rest of the left side compartment with distilled urine up to the indicator arrow ( this is where you may use the dropper thingy ) . go forth the right side of the container empty for this test .
It ’s best to practice distilled water for your pH test , just in case there are chemicals in your pat H2O that will skew the effect .
Step 4 – Shake and wait : break down the palpebra tightly on the container , then shake the heck out of it to mix the soil , powder , and water supply together . Let it sit for about one second before reading the answer .
How to Read Your Soil Test Results
To record your results , hold the test container up to innate light ( but not direct sun ) . Then , compare the colouring of the water on the remaining side to the color chart on the right hand .
If your dirt is really lacking in one or more of the N - P - K nutrients , you ’ll notice that the water on the left field will be almost colorless . On the other hand , the darker the color on the left side , the higher the nutrient horizontal surface in your soil .
you’re able to see from my N - P - K tests ( photo below ) that my soil is deficient in nitrogen ( pink ) , sufficient in potassium hydroxide ( orange ) , and has a surplus of Lucifer ( puritanical ) .
Same idea for the pH soil analysis : plainly liken the colouring material of your sample distribution on the left to the chart on the right field . The color chart will show you how acidic or alkaline your dirt is .
you’re able to see from the results of my pH test ( the unripe one on the right ) , that my land is alkaline .
Blog Post Summary
Soil examination is a game - changer for gardeners at any experience level , and a DIY test outfit ready it so easy to do it yourself . Once you understand your soil ’s N - P - K and pH levels , you ’ll have all the info you postulate to improve it .
