If you want to understand what your garden needs , a soil trial can appraise land health and nutrients to identify any deficiencies . We stress a democratic do - it - yourself dwelling trial with a research lab trial to see how they compare .
If you desire to enrich your soil , use these tips to add together your own compost .
The home test kit could not give a reliable pH level
Do I Need a Soil Test?
If you are like me you started garden for a love of plants but shortly learned that the key to successful development is healthy grunge . Good plants can not overcome poor growing conditions .
If you have a flourishing garden that you routinely fill again with richcompost(decomposed constituent matter ) you many never involve or want to have your soil analyzed .
But , when plants are struggling or there is a fear of soil contamination — particularly in vegetable garden — a test report can help .
dirt tests are used to quantify substantive chemical element in our garden bed and identify any imbalances . You may find you have a pH issue or a deficiency that makes it difficult for plants to maturate .
Popular advice has us adding all sorts of amendments to our gardens without even hump what the problem may be . you’re able to save money and frustration by start out your soil measure and take exactly what it needs .

Soil Testing Options
territory can be tested with a do - it - yourself kit or by a science lab .
We taste both and regain that thehome psychometric test kitwas either imprecise or inaccurate ( see below — it is not deserving the money ) .
A lab has the equipment needed to perform precise tests but the one we used furnish a report that required some research to translate it . I hope your science laboratory is more helpful . you may read about our experience below .
Ideally you will line up a lab that is exploiter - friendly for home gardeners so you not only get valid step but specific and practical good word for improving your soil .
Some state leave free soil tests and you may also have a university extension office to provide guidance .
What Soil Tests Can Measure
you could get a territory test to measure just about any compound or mineral in your grime including organic matter , total salts , macro - nutrients , micro - nutrients , contaminant , and stain pH level . But very few of these are potential to be included in a basic lawn and garden soil tryout that labs offer .
Be sure to read the lab ’s verbal description of what ’s admit with your test , because it varies from research lab to lab . The ones that are about always included are marked with an star .
Nitrogen may be the most authoritative nutrient in your soil , but it does n’t stay in the soil , so a lab wo n’t be capable to measure it with a introductory soil test .
General
Micro - nutrient
Macro - nutrients ( NPK )
Contaminants
The pH scale measures how acidic or basic a inwardness is . The greater the concentration of hydrogen ion , the more acidulous it is .
Some plant do well in soils with modest pH — like blueberries — and some do well with high pH — like cucumber vine , but most plants will mature o.k. in the 5.5 to 7.5 range if their other basic penury are met .
Changing soil pH for an entire garden is not potential . It would be like endeavor to alter the colour of the ocean . It ’s much easier to grow plants that like the type of soil you have . Or use containers for those particular circumstance .

Soild pH Tip
Are yourbigleaf hydrangeaflowers juicy — and do they remain blue twelvemonth after year?That ’s a sign of soil sourness ( with atomic number 13 available ) .
These are the same nutrients listed on commercial fertiliser : atomic number 7 ( N ) , phosphorus ( P ) , and potassium ( K ) . All dirt tests focus on these .
Since a laboratory ca n’t measure your grunge ’s nitrogen levels with a basic filth test , they may supply a general nitrogen layer coarse in your neighborhood .
And , again , if your garden is doing fine , the test really is n’t necessary .
Testing ofmicro - nutrientsandcontaminantswill in all likelihood ask extra defrayment .
Home Soil Test Kits Versus Laboratory Tests
We did two soil test : one using a do - it - yourself domicile filth test outfit that can be purchase at any home and garden entrepot , and one from an accredited laboratory near us that specializes in soil testing for farms .
We were singular to see how the two types of mental testing compared and teach more about our soil .
The soil samples for both tests were taken from the same positioning in the garden at the same clip . If you could afford it , it is advocate to have several samples tested from various parts of the garden to get a better overview .
We did not wish the place kit at all . We only try one ( ordered from Amazon ) but it was awkward to use and the result were not accurate or specific enough . We do not know of others that are more authentic .
Soil analysis at the lab , while more exact , was focused on calculating N - P - K ratios to help you select the right-hand fertilizer ( if you ’re a fertiliser user ) and the amount to use .
This may be what some gardeners want , but we were disappointed that the number we received were n’t given much interpretation . We had to do a lot of delve around on the internet to sympathise them .

The outfit comes with niggling testing capsules that are dissolve in distilled H2O and measured against a color chart .
The directions were not easy to follow and sometimes made no sense .
exemplar
“ Allow color to develop for 10 minutes . Do not allow the color to develop for more than 10 bit . ”
That ’s a rather strict timeline !
Some of the capsules were impossible to open without creating a mess ( and wasting a test ) .
The daystar test would not unthaw as needed and the result were difficult to decipher .
Frustrating to use , gawky supplies , vague or inaccurate result . Not worth it .
Without the proper lab psychometric test ( below ) , we would not have known how inaccurate this test was .

We sent the require amount of garden ground to the laboratory in a clean , shaping nutrient bag via the postal military service .

It was interesting to have some introductory measure of our soil but our arithmetic mean for the report were not met .
This finical laboratory caters to farmers and the reports are not easy for average home plate gardener like us to understand .
Again , the recommendations were for commercial plant food applications and nothing else .
We now know there is a potassium deficiency in our soil but how that is superintend will require our own research .
If you are doing a research lab exam , get recommendations or notice reviews first . read what they will be test for , ask to see report examples , and how the data will be interpret . You may even have a local cooperative extension to assist you .

Conclusions
Would we practice a menage mental testing kit out again ? No .
Would we institutionalise soil to the lab again ? Yes , if we find the need and can find one that allow more thorough / practical advice based on the findings . If we had any business about contaminants , we would definitely get that special examination done .
The best advice is to continually replenish your soil with compost but never add other amendment without first cognise if they are needed . One example is the unneeded use of goods and services of Epsom salt in the garden . Otherwise , the excess goes to waste and can potentially harm the environs .
