what good is a combined total of nitrogen, phosphorus and potash? How do I improve soil if I don't know which of those are lacking?
Asked by: Andy
Thank you for your question. This meter is designed to tell you your pH levels taking into consideration of the available NPK. Based on the reading there is a supplemental sheet/manual within the packaging to guide you in effort to improve soil. If you want to zero in on your NPK then we would recommend using a soil tester with individual tubes to test each. These are also found in stores. Hope this helps and our best to you this gardening season.

what is my model #? should I wet the soil?

Asked by: california
I'm not sure without looking at it. If you still have the package it came in the model number is a 4 digit number on the back of the package in the bottom left or top right corner. If possible you can send a image of the tester you have to and we can go from there. You don't need to wet the soil. Thanks.

Customer Reviews

Electronic Soil Tester is rated 2.1 out of 5 by 13.
Rated 1 out of 5 by from Junk! An acid or a base will give a charge, and this item shouldn't need a battery for that. That said, in college, we were taught to calibrate things with liquids, with a standardized pH. White vinegar is about a 3, ammonia from a grocery store is about a 10. The medium, whether moist soil or a liquid, shouldn't matter a bit; if anything, the jars of vinegar and ammonia should read faster, and be more accurate! This cheap thing stayed on 7, and bobbled back and forth between 6.5 and 8. No real difference whether I tested it in vinegar or ammonia. Scientific verdict? Junk. Give me a no-stars option, and a no-bars choice for my review, please.

Rated 4 out of 5 by from Good for testing SOIL This is for testing Soil. It is not for stuff like the gardenese "topsoil" nor mulch nor orange juice, it is for Dirt. "Organic matter" like wood chips and plant material interfere with the testing and may return invalid measurements. You MUST read the directions and follow them. Also good to note, this measures the Combined total of nitrogen, phosphorus and potash as "Fertility." If you want a detailed soil analysis of your garden soil mix - hire someone. If not, you should use the one-time soil tests with the little vials for every factor.

Rated 1 out of 5 by from Doesn't work AND falls apart--don't waste your time. "The Soil Tester" just plain didn't work. I followed all the directions to the letter several times. The meter read 7 pH for everything except for a weak bleach solution when it went to 9 pH for a second and then dropped back to 7. I used litmus paper to verify that the unit was not functioning. It instructs you to polish the aluminum probe with the included green cleaning pad. When I applied a little pressure the probe fell out. It's not designed to be disassembled--there are no screws on the back. It's a piece of junk that they are betting most people won't bother to return. The $10 model is so bad in fact, that it's not even available on the Ferry-Morse website. I think they're ashamed of it. At this time it's got one good review and one (my) bad review. Maybe you have a 50/50 chance of getting one that actually does what it says before it breaks! Thankfully, Home Depot's return policy is great!

Rated 4 out of 5 by from Appears to produce accurate results I'm not sure why all the other reviewers are having trouble getting accurate readings from this device. Before testing my soil, I did some semi-scientific testing to see if the device actually works. In short, it appears to work as advertised. I immersed the rods in vinegar (a known acid), and the pH meter jumped down to 2. I then immersed the rods in soapy water (a known base), and the pH jumped to 9, wihch is the maximum alkaline value on the meter. When I tested my soil, some areas of my yard showed as roughly neutral (~6.5-7 pH). Others showed as slightly acidic (~5 pH). I tested each hole several times, and achieved consistent results with each test. In my book, that shows that this device works. Some of the other reviews mention the device breaking easily. What, are you jamming it into the ground with the force of a thousand earthquakes? It's made of plastic. I's obviously not industrial-grade. In fact, I'll knock off a star because it does feel a bit cheap. But what do you expect? It's a $10 product.

Rated 1 out of 5 by from Pure Junk I should have known something that didn't even require batteries would be junk. I fallowed instructions to the letter and this meter, no matter the conditions, it barely moves one way or the other. I wanted to see if I was right about the product so I put it to the test. I put it in pure wet fertilizer and it barely moves off center. Put it in a lemon and it shows a ph of 6. Put it in a cup of baking soda and water and it has a ph of 7, yea right. Don't waist your money!

Rated 5 out of 5 by from It works Excuse my english knowledge. Every time you use the tester you most clean it if possible with a fine sand cloth in order to a reliable reading ie. if you test vinegar give 3 and so on. You most read the instruction and follow it worth the price and utility

Rated 1 out of 5 by from Don't Waste Your Money At first, I tested the unit in an acid and in an alkaline, and the indicator moved between 6.5 and 7.5. I thought perhaps the unit needed calibration (as I have the fancy-pants unit requiring a battery), and searched for Ferry-Morse online. You can't find a FM website, because the company was sold to Jiffy (maker of gardeners seeding pellets and trays, etc.) in 2005. The unit seems to work for some people, but if it doesn't work for a similar number, as indicated here, it's like taking your hard-earned cash and putting it on a roulette table. Do you want to do that with the food you're trying to grow? I'm going to return this unit, and put that money and a little more, on something dependable.

Rated 1 out of 5 by from JUNK The readings on this meter never moves past 7 or 6 no matter what you do. It is truly worthless, I threw it away.
