According to our production experience, when crops grow slowly or stop growing, it is certainly due to lack of nutrients and need to be topdressed. However, in many cases, this is not the case. The slow growth of crops or the stoppage of growth may also be due to soil. Salt is too high, causing the root system to absorb nutrients is difficult, resulting in nutritional deficiencies, so this time should not blindly top dressing supplement. Instead, soil salinity meters should be used to detect soil EC values ​​first, to avoid re-accumulation of soil salinity caused by unreasonable fertilization and to accelerate plant death.

In general, plants can only grow well in the proper soil salinity environment, normally absorb nutrients and water, and at different stages of plant growth, the degree of adaptation to soil salinity is also not the same. Take tomato cultivation as an example, tomatoes The ec value at the seedling stage is preferably about 1 to 1.7; it is preferably about 2 to 2.2 when the tomatoes are in fruit setting and the plants are vigorous. However, the most ideal EC value for most plants is usually between 1.2-1.8, and the maximum should not exceed 2.5. To ensure that the soil salt environment meets the plant's growing needs, the simplest and most effective way is to use a soil salinometer for testing, if not In line with this, measures can be taken to improve the growth of the plant's roots and accelerate their return to normal.
In addition, when there is a problem with plant production, the soil salinity meter is first used to detect the EC value of the soil, and the problem of plant growth can be discovered and analyzed in time to determine if it is necessary to top-dress and supplement soil nutrients. This can be avoided through scientific diagnosis. The soil pollution caused by blind topdressing and the increase in agricultural production costs, on the other hand, can effectively promote the growth of crops, increase the yield and quality of agricultural production, and realize the grand goals of ecological agriculture and efficient agriculture.
