Received meter today. Went right out and gave it a try. Problem number one, which isn't a flaw of the instrument, is it measures LUX, 1 candle placed one meter above an area 1 meter square. In other words, a candle power.
Not a great deal of use in trying to figure out how much light my plants need at various stages. (I knew this going in, so this isn't a bitch, just an admission that I didn't think things though before purchase) Finally found measuring PAR would be better, and that confused mr no end.
Any way, I found out with my trial run, that measures Ph accurately. The moisture, I am not to sure of. It measured three plants that I thought dry as wet, but one I knew to be dry it measured as dry.
Also, determined that the 10 minute wait period is necessary for the meter to calibrate itself. The immediate measure of moisture was past the 10 on the scale. Ten minutes later it had dropped to 8 on the moisture scale. That has to be done at each plants location.
So far I'm very pleased with this product. I think that the few negative comments have been made by people who don't understand the science of sampling and data collection. They don't realize that with any device used for measurements, there will always be a sampling error.
They think if the device doesn't record the same result every time then there's a problem with the machine. Yes, you can place the probe into soil at different locations in the same pot or garden area and it may record slightly different readings, say maybe 6 at one spot and 6.5 at another.
But for the price of this device, it is very accurate. Also, many comments were made that they inserted the probe into a glass of water and it didn't read "wet", when the instructions clearly say not to do this.
There were comments made about the probe being a weak spot in the device, and would break off.Yeah.... If you try to use this as a pick axe or a fence post. You're not supposed to beat it into the ground with a sledge hammer.
This product does exactly what it says it does!Efficiently too! This product is 3 bottles pH-up, pH-down and a pH test solution. (also comes with a vial to conduct the pH testing in AND a pipette which I thought was great, I ended up getting on before I opened the package assuming they did not provide one, but General Hydroponics really gives you everything you need to open the package and do testing RIGHT AWAY!
I tested this on my hydroponic system with a calibrated pH meter hehe..... I wanted to know how accurate the test solution is. The test solution runs on a color scale, acidic being pink basic being dark green. The scale is located ON THE BOTTLE!
So you never will lose it. As far as my basic testing concluded, the test solution is accurate; the color changes are visibly recognizable and comparable to the provided scale.6.0 is yellow, 7. 0 is green, and both of these matched my pH meter (in approximation, don't expect to perfectly get a 6.
This is exactly like the one I bought at a big box store many years ago, except that it was black plastic and did not have a brand name on the meter. In every other respect they were identical in every detail.
When my old one finally gave up the ghost this Fall I bought this one to replace it. I noticed several other listings on Amazon that look the same except for the name on the front of the meter. I was very happy with my old one and this new one as well.
It is important to know whether plants are getting enough moisture. Different plants need different amounts. The package contained a listing of a number of plants and their requirements. Sometimes after a heavy rain the ground is saturated for a period of time even when the surface is dry.
If you water too Mich you can cause the roots,to rot, and,then the plant dies. With the probe you are checking the moisture content below,the surface.
Worthless junk.PH reads the same no matter what soil you place it in? Flip the switch to moisture while in the same soil and readings do not change? Only 1 of the 3 that seem to read correctly is the light meter.
Sadly the only one of the 3 I did not need. I bought this to measure PH for the different plants separated out in my elevated 10 X 10 garden. All of the separated portions read the same. Which it starts out between 7 to 8 on the scale.
And does not vary no matter what soil you check. Maybe just a bad unit? Should have gone the extra money for a working PH tester. As I NEED to see the real PH balance in each of my different plant types.
Tjhey all can not be 7. 2 in every container or every part of my yard which also all read the same.....Update.7 3 19. Customer service for this seller is awesome. After having a bad experience with the 1st product. I just posted a review and threw it in a junk drawer.
I laid new Bermuda grass in April and put new soil and tall fescue just two weeks ago. The flowers I've planted in the flower beds along the way. One has succeeded and the other has been a garden of death and that was the reason for buying this soil tester.
I want to show everyone what I received out of the box. I got home and went straight to the yard because my sprinkler system had just watered and the soil was loose. I have a small screwdriver that I initially used to make the holes to insert the probes.
I soon found they were not as fragile as people claim and only had to use it in a couple areas. But, I do recommend using the screwdriver method in case you have rocky or clay lawns. You have to use common sense.
If it doesn't slide smoothly into the ground, why force it in. As for the rest, the pictures I uploaded speak for themselves. Every area was a little bit different and most importantly, I got a great overall picture of what is happening with my lawn and garden areas.
I am very sorry to report that this meter isn't very useful for my needs (growing succulents outdoors in containers in the Bay Area). The problem is that the sensors read the same unless conditions are truly extreme. For example, the light meter does show a high reading for bright sunlight directly on the sensor.
But it can't tell the difference between bright shade and deeper shade. The moisture meter - which was my reason for buying the item - registers in the red, "Very Dry" region unless the meter is placed in soaking wet soil.
Then it does go all the way to "very wet". So, the moisture meter is probably useful for soil that is usually quite moist, to warn you if it dries out. But it's not useful for succulent growers. (Maybe if you haven't figured out yet why all your succulents die...
At first I wasn't sure if it worked or not, testing it in the dozen potted fuchsias I'm overwintering in my garage under lights. The reading varied from 2 to 3. 5 in each pot however, so I figured it is measuring something.
Then I added 1/4-1/3 C water to each pot and saw almost no change in the meter readings. I took it outside and stuck it into the moist ground in my back yard-same result, right around 3. I stuck it in a glass of water and it read dry, so it occurred to me that it's measuring something that's not present in pure water, perhaps ions that are only present in soil.
Finally I went back to the fuchsias and pushed the tip all the way down to the bottom of the pot-the meter read 6-7 in a few of the pots, but still 3.5 in one of them. The answer was obvious-the water had gone directly to the bottom of the pot, not to the roots, which were mostly still in the middle portion of the pot, due to being recently repotted.
A friend recommended this plant meter. I am happy with it, the product does exactly what I need it to do. I am mostly interested in the moisture reading and it seems to do a great job. It is easy to read, easy to use and a good value for the price I paid.
Outstanding product and service. I have both an old lawn in pretty rough shape and an area that I am putting in a new lawn. I decided to get 2 kits one for each area. Before I bought the product on Amazon I called the My Soil company at the number Amazon provided for them.
I talked to Chris at My Soil who was very informative on what made their product different than others I had looked at. He also gave me pointers on getting the test kit sample prepared and shipped back as well as what I could expect from them when the results came back.
The whole process could not have been simpler! In total it took 10 days from the time I ordered the kits on Amazon till I got the results online from My Soil. The results are easy to read and include recommendations for the type fertilizer I need to bring the soil to the right balance for the lawn I plan to plant.
I really do like this product, it is very easy to use and appears to be accurate. I have some plants that like to be moist but not wet, it was always hard to judge how much moisture they needed, but this product takes the guess work out of it.
I can put the probes down into the pot and tell when the plant needs to be watered. Sure wish I had purchased this a long time ago.
The biggest issue is the cores get stuck in the tube entrance. The more expensive soil samplers have a tapered end. This means the core sample is a little bit smaller then the inside diameter of the tube. My plan going forward is to find a dowel rod to pop the cores out.
The end is sharp, so using your finger is not a good idea. Took about three weeks from the time I placed the order till delivery. It was shipped in a plastic bag. Bonus, it has rubber handles and an end cap!
I see other reviews on here talking about "send your soil in to a lab" or other alternatives to this product. Fact is, if you were willing to spend the money to send your soil to a lab, you probably wouldn't be buying this.
Probably like you, I bought this because it's cheap and it'll give you a basic idea of what's going on in your garden. Here's how it works:You get 4 vials, one for soil pH, and one each for Nitrogen (N), Phosphorus (P) and Potassium (K).
Essentially, you place the directed amount of soil/water mixture into each vial, and add the contents of the corresponding color-coded capsule. The capsules look like pills, the type you can pull apart and the contents spill out. After you empty the capsule into the vial, you place the rubber cap on the vial, shake and let it sit for the specified amount of time.
Okay so I'm new at this whole, keeping plants alive thing, and so I thought I would get this just to make sure I'm keeping the soil in the right state. Upon opening it, I was a little skeptical because it seems kinda cheap.
Then I realize it doesn't take batteries... Hmmmm I think this is going to a bust I tell myself. After already giving up on it, I decide to try it out and see if I'm missing something....Like no batteries??What?!
Anyway, I flip the switch to PH, find a nice little spot and nestle it in the soil, and VOILA!!It's like magic! It gave me a reading!WHAT?! Excited, I go to the next happy plant, to see if it will give me anything and BOOM!Works again!
I love this little I don't know how it runs or works gadget and would definitely purchase again.
As they come from the factory, these (at least the two I got) seem to only be good for desert plants (cacti & succulents) that need to be totally bone dry before watering. First let me debunk a couple of reviews I read that said these were 'crap' because when the customer put them in a glass of water they read 'dry'. They are NOT made to read the presence of PURE water!
They only take a reading on water that has impurities. I got some clean pure water, stuck the probe in it and it read 'dry'. I then boiled the water and made a cup of strong black coffee, and a cup of strong black 'Earl Gray' tea;stuck the probe in each one of those and the meter pegged over to a 10++ reading.
If you get a pot of good soil, and soak it well with water until it's dripping out of the bottom of the pot (waiting until all water dripping stops first) and then stick it in the dirt, it also reads 10++.
This moisture meter works just fine. For all the reviewers who stuck this moisture meter in water and claimed it was junk because it read "dry"-(*facepalm) that's not how moisture meters work! Such devices are designed to measure the electrical conductivity in soil, not the "wetness" of water.
I haven't ever met a moisture meter that would read water. For those who said that they just watered their plant and it still read dry... I would wait a good hour and test again. Depending on the type of soil (many types are quite hydrophobic, especially when bone dry), it takes a while for the soil particles to absorb the water.
Sometimes seeing the water draining from the bottom is not enough. It can run right through if the soil is bone dry. Let it sit and water again after 30 mins. Then wait a while and test again. Another possibility on that one would be that the soil was so saturated with standing water, the meter could not read the soil because it only had contact with water (similar to what happens when you place the meter in a glass of water).Anyhow...
As soon as I got it I tried it out and watered the plants that needed watering. The meter seemed accurate based on soil that I knew was very dry and soil that was moderately moist. It gave readings that matched those soil moisture levels.
I guess I don't know that it is perfectly accurate, but it did register according to what I knew the soil was. I haven't tried the PH function yet, but will add to this review if it moves me.
This product seems to be fairly accurate from what I can tell so far, especially in comparison to the probes which aren't accurate at all. Easy to use, simply mix soil with water equal parts dip for a few seconds and read.
FAQs on Soil Test Kits
Unless you are growing grass, your soil is pretty useless. Fruits and vegetables need amended soil. That's why the big box stores sell garden soil, potting soil, compost, mulch etc. By the time you get your soil ready for real plants, your dirt will not need to be tested because you know what you put down.
So, I don't know if they are accurate, but I do know they are useless. Spend your money on a soil thermometer instead.read more

FirstWhat are your concerns? If this is farm land then you may be interested in the fertility of the soil which can be tested by any reputable facility. However, if there are concerns about some type of pollution then more extensive examination should be done by an environmental engineering laboratory that specializes in testing for contaminants.
SecondThere are natural treatments of the soil that can help eliminate, or at least, reduce the level of residual pesticides, herbicides, etc.In the soil. Apply the best compost that you can afford wherever you intend to grow fruits and vegetables.
You may begin with spraying the soil with a molasses solution to encourage beneficial bacteria in the soil.read more
I am a student and as for testing soil analysis we used Niton XRF sprectrometer which at that time needed calibration and would say that it was not correct but its data can be used as reference for at least to know what the soil lack of, has enough.
For this type of analysis you have to do more repetition of analsis but it gives you a nice results. Photoelectric photometry (flame) i would say that is an important tool to use to determine the soil nutrient availability of soil and their amount in the soil.
And another one that i worked i gave correct result i would say is the case of chemical soil analysis kits which i used in laboratory were correct. It has its own protocols, in case you want correct result you have to be precise to follow the rules in there.
These three are kind of some that i know how its done the job. But actually i always had the results which now i understand that i did not do the interpreting' of data. I think that is important to be clear when do prepare the samples and to stay on track of the work.read more
