Soil EC value refers to soil electrical conductivity, which is an important indicator for determining soil water-soluble salt, while soil water-soluble salt is an important indicator of mineral nutrients in the surface soil that can be quickly absorbed by plants, and is used to determine whether salt ions in the soil Factors that restrict crop growth. Too high or too low soil EC will affect the growth of crops. Different plants have different suitable soil ECs according to different fertilizer characteristics and growth stages. Generally between 0.4 and 1. The soil EC value can be measured with the help of a special soil in-situ EC meter . The advantage is that it can be measured anytime and anywhere without collecting samples. It can be quickly measured by inserting the sensor into the measured soil, which is very convenient.

At present, excessive and blind fertilization are still common in agricultural planting. Although there has been emphasis on reducing the use of chemical fertilizers and advocating scientific planting, since most of the soil, especially the greenhouse soil, has accumulated too much salt in the past few decades, the soil salt has begun to seriously affect the normal growth of crops . So we must pay attention to the index of soil EC value.
In flower cultivation, soluble salt ions mainly come from irrigation water and fertilizer solutions. Production managers should often use soil in-situ EC meters to measure EC values ​​to avoid excessively high concentrations of soluble salt ions in the planting medium. Taking the production of phalaenopsis as an example, the suitable growth EC value range of phalaenopsis is 0.8 to 1.2. The measurement method is: collect the water discharged from the planting medium after irrigation, and measure it with a soil in-situ EC meter. If the EC value exceeds 1.5, it indicates that the medium in the basin has been salted, and it needs to be rinsed with clean water.
In general, by measuring the EC value in the planting medium with a soil in-situ EC meter, you can indirectly determine whether the plant is nutrient-deficient or over-nutrient. Therefore, the concentration of soluble salt ions in the fertilizer solution should be tested before plants are fertilized. The EC value of fertilization for different plants is different, and the EC value of fertilization for the same plant at different growth stages.
