Soil pH
Soil pH, also known as “soil reaction.” It is the soil solution of the acid-base reaction.
Mainly depends on the concentration of hydrogen ions in the soil solution at pH values. pH of
the solution is equal to 7 neutral solution; pH of less than 7, the acid reaction; pH value greater
than 7 is alkaline reaction. Soil pH can generally be divided into the following levels:
pH of soil pH
<4.5 strong acidic
4.5-5.5 strongly acidic
5.5-6.5 Acid
6.5-7.5 neutral
7.5-8.5 Alkaline
8.5-9.5 strongly alkaline
> 9.5 strong alkaline
Soil pH on soil fertility and a great influence on plant growth, China’s northwest, north many
soil pH value, pH value of small red soil. Therefore can be grown and adapted to soil pH and
plant crops. Such as acid red soil area planted hi tea, and strong alkali such as alfalfa. Soil pH
effects on nutrient availability is also great, such as neutral soil phosphorus availability large;
alkaline soil trace elements (manganese, copper, zinc, etc.) effectiveness is poor. In agricultural
production should be noted that the pH of the soil, and actively take measures to adjust.
Common crop optimum soil pH range is how much?
Soil pH on plant nutrient availability, soil structural and crop growth have a great relationship.
First, soil organic state by microbial nutrients to participate in activities in order to make it
into nutrients for plant uptake of available state, while the majority of microorganisms involved
in decomposition of organic matter in the near-neutral growth environment, so the effective soil
nutrient in general close to neutral reaction is the best. Secondly, structural soil pH also affects
the soil. Acidic soil, the hydrogen ion concentration, easy to colloids leaching out calcium
substitution, it is easy to acidic soil compaction. The substitution of the alkaline soil contains
large amounts of sodium ions and hydroxide ions, so that soil particles dispersed, dry compaction,
resulting in poor structural earth. In addition, soil pH and plant growth also has a very close
relationship. In nature, some plants on soil pH conditions demanding that they can only be in a
particular pH range grow, these plants from the soil pH can be indicative that, so called
indicator plants. Such as azalea only grow in acidic soils, known acidic soil indicator plants;
Kashiwagi is calcareous soil indicator plants, and salsa is an alkaline earth indicator plants.
Different cultivated plants have different optimum growth pH range (see table below),
knowing their respective optimal growth range, we can according to local conditions based on soil
pH, choose the right crops; or according to crop, adjust the soil pH to the proper range.

  1. A***o

    Everything is fine, I will buy more.

  2. J***n


  3. M***n

    Works great. I ordered 2 pieces.

  4. M***n

    Works great without any dancing with beads.

  5. E***a

    In the non-working position shows the same indication. No instructions. Packaging leaves much to be desired.

  6. V***v

    Delivery fast, packing quality. The power device does not require, as inside only the coil. I performed ten measurements of soil in different conditions, but the readings of the device slightly deviate from 7,0. And only in liquid 4,0 the device showed a value of about a little less than 5.

  7. V***a

    The device came quickly. Packed well. We haven't tried the case yet.

  8. N***v

    The packaging was opened, but the thing works. Good product. Thanks to the seller, delivered in the specified time

  9. V***v

    The parcel came quickly, very satisfied, the device works.

  10. A***v

    Shows exactly

  11. M***v

    Everything works. Checked on different seedlings and gives minor deviations from the norm

  12. A***a

    The device came in whole in good condition. I had time to try, the readings are close to those who measured litmus paper. I did not think that on one bed in different places can be from 5,5 to 8,5! Disposable testers do not intend so much samples. An indispensable thing in the country!After the test, you need to give "rest" a couple of minutes that would have dropped on neutral, otherwise the next measurement will be incorrect. After each use it is necessary to remove the ground from the probe and wipe it dry. I do it with a soft cloth. The particles of the earth are clogged into the joint of the tip of the probe and the rod itself. I do not know how this will affect the work. You can clean with a toothbrush, for example, but not every time, or then quickly loose.Ph measures more precisely than similar devices "3 in 1". I am happy with the purchase, i recommend.

  13. A***o

    Ph meter, whether it measures or not, everywhere shows 7, with pts. Slight deviations. = D

  14. G***y

    Aaa +++ very fast shipping!

  15. P***l

    thank you very much, your pH Meter arrived today and is well working

  16. A***v

    Fast delivery (early). Packing is standard, the device is not damaged. The arrow of the device is in position 7 (neutral environment). I thought that it was necessary to insert batteries, opened the device and was very surprised that inside there is only the scale to which the sensor is attached. There's nothing else. I tried to plug the sensor into the flower pots. The arrow deviates, i.e. The device one hundred then shows, but how accurately it is difficult to say. I think the readings will depend on soil moisture. If it turns out to compare with the acidity data defined by the litmus paper.

  17. K***v

    The goods went a month to bryansk. the packaging was a little encouraged. But the device is not damaged. how accurate the readings are when measuring i do not know. For me, the main thing is to determine the acidity of the soil for the cultivation of blueberries. checked in work. reacts to acid soil.

  18. D***d

    Item arrived damaged

  19. D***d

    Delivered cdek for 100r, for 6 days, air shows 7, soil 6,2, h2so4 electrolyte 1,28 off scale

  20. I***v

    Super, delivered to the house for the 4th day. checked, works.

  21. S***a

    Everything works fine.The longest shipping i received.

  22. S***a

    Everything works

  23. O***v

    Excellent "unit". Soil acidity shows quickly. And the more acidic the soil, the faster the indication is formed. The meter works without batteries. I recommend for the order. The seller sent everything in the terms indicated on the site
