I have a large lawn of St Augustine grass.......15,000 sq. ft. I wonder if this is the proper PH meter for testing such a large area.

Yes, it has been working very well for me with Golf fairways and greens. jqgriswold@gmail.com

No, it is designed for testing moisture in dirt. If you use it to test the moisture in wet clay balls, or pebbles, it will either read fully wet, or dry. The air around the medium for hydroponics is either dry, or full of water during the flow and ebb cycle. The pH reading requires very wet mud, or liquid for a reading, but the reading isn't as accurate as pH test strips.

A standard litmus kit cannot accurately test the pH of water due to the chemical traces on the strip and the reaction process..... Seriously? Those chemical traces and the reaction process are EXACTLY how pH is determined. This is like saying a speedometer can not be used to measure speed because it measures distance traveled over time...... /smh

I really can't answer that in terms of sq footage but I ordered a gallon of PCO spring of 2012, have sprayed our 1/4 acre yard & large raised-bed garden 3 times per summer and our cottage lawn and edge of woods several times this year and last year with about a 1/4 of the bottle remaining. I also used a bit more than recommended. It's very economical when considering the area it's covered. Wish I could be more helpful. It really took care of the fleas in our garden area which is all pea gravel. Also, I think it cut down on the amount of ticks at our cabin. Good luck! There used to be a video on the website but that seems to have been removed and the website changed so I'm not sure what's happening there... Hopefully the company isn't in trouble. I really do believe their product helps and I don't have to worry about our dog and kids playing in the yard with this natural product...

It depends how many samples you take. Don't over do it, divide your lawn into 6'L x 8'W sections if your lawn is more or less the same throughout. Refills are not cheap and found here or on ebay. If you must add a nutrient/mineral, stay low than what the table recomends and spread it well. Unless you have a huge amount of grass, forget the refills and just buy this product again in 4- 6 months.

You have to calibrate it. It was beyond me. But i had a friend who'd done well in chemistry. He was unsuccessful in getting a reading that made sense, but I blame that more on him, than the reader. I would look for a pre-calibrated meter for someone with limited tech skills. i needed it to test PH in pond water. I have several mud ponds. The PH is a little different in each of them.

You know, I am not sure what St. Augustine grass looks like, but it really works well on medium and low height grass. Not so much on anything tall.

I use it on St Augustine grass and have used it on Bahai as well. It takes a little while to take effect but works well.

One gallon is WAY more than enough for 1750 sq ft.... The concentrate dissolution is 3 tablespoons per gallon (1.5 oz per gallon) I put 3 gallons of water and 5 oz of Killzall in my 4 gallon backpack sprayer (3 gallons because I don't want to carry 24 pounds around at first as I spray....) Those 5 oz cover about 1/4 acre, the way I spray (a little over 10,000 square feet_ I spray my entire 3/4 acre grass area in February/March when the Bermuda is dormant.... killing everything green in about 3 weeks.... wilt starts in 3-4 days depending on temperature. Surrounded by pasture, I have a lot of noxious weeds and grasses that stay green in winter. Great product!

I would imagine not to much since your ph is already 5.5. its intended to get water probably to around a 6 or 7 but 5-7 is about the normal range. i haven't actually tested my ph with this device before and after so i couldnt tell you to be exact.

I wouldn't recommend this to you. I have terrible results. Try ammonium nitrate on your lawn. It works wonder for me.

I have used it to measure soil moisture in our lawn, around trees and just about everywhere else. I believe it to be very accurate. I bought it because I found that the soil moisture gauges in the nurseries around here were not accurate. Of course, the accuracy depends on following the directions that come with the meter so assure accuracy. I have found the device to be accurate and useful. I would not give it up.

I use the tester to check the acidity in the water for my plants. I add lemon juice and vinegar (equal Parts) to raise the acidity in a five gallon bucket of water. So I will say yes to your question. The tester seems to work better in water than in soil. I hope this helps.

I assume you mean, "How large an area" and I think an ounce was good for about 1,000 square feet. The container I bought (5 pounds) it going to last a lifetime since my lawn area is only 8,000 square feet.

You can test pH of a soil, but not by sticking the probe in the sample. Do do so, you'll need to put a sample of the soil in some distilled water (RO would do) to form a suspension (try not to make it thick or else the pH meter will not read effectively). The more you shake the suspension prior to reading, the more accurate your results will turn out.

I had the same question. The 5 pound container is supposed to cover 3 acres. I took a wild guess and mixed one third of my 5 pound container into my 4 gallon sprayer. This should be enough to cover one acre but I sprayed roughly one half acre with the four gallons which means I was spraying double concentration. I don't mind the overkill but I'm sure that 1/6 of the 5 pound container mixed into my 4 gallon sprayer would have been sufficient. Nothing has sprouted since I sprayed a couple months ago so it seems to be working.

Jay, Did you not read my response? I explained how to treat the acre; here's a copy and paste of the text below: "...for broadcast spraying, it says 1/2 to 1 oz per 1000 sq/ft of turf. That adds up to 22-44 oz per acre." I tool this off the label. Now I know you've been saying one is supposed to use 3 oz to a gallon of water but I couldn't find that rate anywhere. But what I did find is either 1/2 oz up to 1 oz per 1,000 when broadcast spraying so at most, you'd need around 44 oz per acre.Jonathan
