Rating of the best soil acidity meters (PH-meters) for 2024

According to numerous observations of gardeners over the process of growth and development of various crops, it was concluded that the same plants do not feel equally comfortable on different types of soil. One of the most important reasons for this is the acidity level of the substrate. Therefore, it is so important to have a soil acidity meter or pH meter on hand.

Soil acidity scale

Since acidity is the presence of hydrogen ions in the structure of the earth, more or less of them determines its level. It is designated pH and has its own scale. The 7.0 is the middle of the scale and means that the soil is neutral. The values ​​to the left of this figure indicate that the acidity of the earth increases with decreasing numbers on the scale. And, conversely, with their increase, the degree of acidification becomes alkaline.

The optimal acidity level for horticultural crops

All vegetable plants, fruit shrubs and trees are very sensitive to acidic soil, and many of them are not able to thrive and bear fruit well in such an environment. Therefore, before planting, it is recommended that experienced professionals check the acidity of the soil and, if necessary, reduce it by neutralization.

So, for example, below is a table with an acceptable pH level for vegetable crops:

Culture	Optimal pH
Watermelon, strawberry, rhubarb, potato, chicory	5,5- 6,4
Tomatoes, peas, cucumbers, corn, carrots, beans	5,8-6,4
Asparagus	6.2
Cabbage, broccoli, beets	6,2-6,6

What is the need for measurement?

One of the most important reasons why it becomes necessary to check the degree of acidity of the soil, to obtain the maximum and high-quality yield. To achieve this, the plants grown should be provided with the most comfortable and favorable conditions. For the nutrition of crops, substances are needed that are in the ground in an appropriate state. The same structure should be applied to fertilizers applied to the soil. But in the presence of high acidity, such a result is very difficult to achieve. As a result, the plants will be sick, develop poorly and will not give the expected yield.

Therefore, experienced agronomists very carefully prepare the soil before sowing, adding certain necessary means to neutralize or alkalize it.

Methods for determining the value of acidity

There are several ways to find out the degree of soil acidification. This can be determined visually, chemically or by measuring with special devices.

The first method is very general, as it is determined by the plants growing on the measured area.

• If sorrel, blueberries, horsetail, oxalis and moss grow violently on it, then we can safely say that the ground under them has a pH level of 5.3 to 6.0. It's a sour land.
• A shepherd's purse, common chicory, wheatgrass, feather grass, creeping clover, carnation, sow thistle, bells, who feel comfortable in the area being inspected, indicate a neutral degree of acidity. Its values ​​are in the range from 6.0 to 7.2.
• The presence of pines, sowing chestnuts, as well as thickets of field bindweed, alfalfa, coltsfoot, thyme, sedge, May lily of the valley or Venus's shoe indicates an alkaline structure of the soil. Its value ranges from 7.3 to 8.1.

The second method is more laborious and not entirely accurate. It only allows you to recognize whether the soil in the area is acidic, neutral or alkaline. To do this, it is necessary to carry out certain experiments with the soil, adding vinegar, soda or other components to it. By the received chemical reactions or their absence, it is possible to determine the quality of the earth. But it is quite problematic to achieve a digital value from such an option. But even a tenth of the value can have a significant impact on the cultivated crop.

Also, the determination of a strip of litmus paper on a color scale belongs to the chemical method of measuring the pH of the soil. By contacting it with a well-damp ground, it changes color depending on the condition of the soil. After comparing it with the gradation presented on the package, you can find out how sour, neutral or alkaline it is.

The third option is very convenient, accurate and practical. By immersing the electrodes in the ground, the pH level or lack thereof can be determined with great accuracy.

America is currently the main country-developer of such meters. For several years, manufacturers of Western companies have produced only highly specialized pH meters, but recently they have switched to the creation of more universal models that allow measuring not only the level of soil acidification, but also moisture, the amount of nitrates.

Litmus paper

Measuring the acidity of the earth using strips of litmus paper is the simplest and most budgetary option. A set of color-scale strips is available from some pharmacies or online stores.

Mode of application:

To carry out the procedure for determining the pH of the soil, it is necessary to take a quality sample. It is recommended to use the earth from a depression 20-25 cm long. Place it in a deep bowl and add some distilled water. Mix thoroughly and leave for 15 minutes. Then stir well again. Then put a strip of litmus paper on the ground and wait a few minutes. By the obtained color, which the litmus acquired, it is possible to determine the degree of acidity of the soil by comparing it with the scale presented on the package.

Indicator value by color

• Bright red color or its shades indicate high or increased acidity of the soil.
• Green and the shades closest to it speak of its neutrality.
• Yellow and pale yellow represent the alkaline degree.

For the general determination of acid in soil, litmus paper with a large color scale can be used. To find out a more accurate value of the result, it is advisable to use litmus strips with a fine scale step.

Of course, with so many possible options for choosing pH meters, there is no need to rush to buy, but it is advisable to carefully think over and determine your occupation, the required range of functions of the device. Having chosen the most convenient, high-quality universal or specialized meter, compare prices and give preference to the most optimal option.

We hope that the selection of characteristics and preferences of users of devices of this category, presented in the article, will become an indispensable assistant for everyone in their choice.
