Inexperienced gardeners are faced with many problems in arranging their own garden. Why do potatoes grow beautifully in one section, and instead of beets, you get miserable “tails”?The answer lies in the type of soil, depending on which you can get an idea about the set of necessary elements, its density, moisture capacity and air permeability.
An equally important parameter when choosing vegetable crops is soil acidity. Sample delivery to a specialized laboratory is considered the most reliable way. In addition, it is possible to determine the acidity of the plants on the site. Recently, however, the advanced owners of the "six hundred parts" use special testers for the soil. 
The cost of a miracle device in Russian online stores is from 500 to 700 rubles. The most important advantage of the tester - unlimited shelf life. All data is obtained on the basis of a chemical reaction, which means that power sources for the device are not needed. As a rule, the tester provides three parameters at once - illumination, acidity and soil moisture.
The device allows you to measure not only the quality of the soil, but also to adjust the frequency of watering plants. Even a beginner gardener will cope with testing. Special probe must be entered to a depth of 10 cm and wait at least two minutes. The data obtained correlate with the table that comes in the kit, and only then take steps to correct the soil.
On the AliExpress website, soil testers are especially popular because of the attractive price - 200-300 rubles per item. Despite experiments with soda and vinegar, buyers still have doubts about the accuracy of the devices. In addition, the process of measuring soil is complicated due to the lack of instructions in Russian. After each use, the probe tester should be cleaned with a dry cloth.
Some reviews advise making a choice in favor of digital testers( price 900-1100 rubles in China and 4000-5000 rubles in domestic stores).The only drawback is a long delivery - up to 70 days, but if you make purchases before the summer season, feel free to place an order with one of the sellers on AliExpress.
The differences between Chinese and Russian testers are minimal, and with the money saved you can buy seeds or special fertilizers.
