EC Value For Tomato

EC value refers to the electrical conductivity of soil and is an important indicator reflecting the content of water-soluble salts in soil. The level of EC value determines the fertility of the soil and suitable crop planting, and also has an important impact on the growth of tomatoes.

Within the appropriate EC value range, the growth ability of tomatoes will be greatly improved. Too high an EC value will lead to excessive salt concentration in the soil, which will affect the normal growth, development and yield of plants, and may even lead to reduced quality and death of tomatoes. Therefore, it is very important to maintain appropriate EC values ​​when growing tomatoes.
The EC value is used to measure the concentration of soluble salts in a solution. It can also be used to measure the concentration of soluble ions in liquid fertilizers or planting media. The unit of EC value is expressed in mS/cm or mmhos/cm, and the measurement temperature is usually 25°C. High concentrations of soluble salts can damage plants or cause root death. The normal EC value range is between 1-4mmhos/cm (or mS/cm). If the soluble salt content (EC value) in the substrate is too high, reverse osmotic pressure may be formed, displacing water from the root system, causing the root tips to brown or dry up. It is generally required that the EC value of irrigation water is less than 0.8ms/cm.
