The EC index reflects the amount of dissolved salts present in the soil solution. When this level changes, the nutrient status and the root's absorption capacity also change. This is why EC is often monitored throughout the cultivation process.
According to specialized literature, the electrical conductivity (EC) of soil is typically between 0.2 and 1.2 mS/cm. This is the range within which plants can absorb nutrients relatively stably. When it falls below this threshold, the amount of dissolved ions is insufficient, leading to nutrient deficiencies. When it exceeds this threshold, the salt content increases, affecting plant growth.
Electrical conductivity (EC) is a fundamental parameter in water quality assessment. This index reflects the ability of a solution to conduct electricity through dissolved ions, including metal salts and inorganic compounds such as NaCl, KCl, nitrates, or phosphates
The ability of metals to conduct electricity stems from their unique crystal lattice structure. The electrons in the outermost shell are not stationary but move freely, creating an "electron sea" surrounding the nuclei.
Light directly impacts the quality of daily work, from factories and offices to greenhouses. Many businesses encounter the same problem when starting to buy a light meter: there are so many specifications, but they don't know which one to choose. This article focuses on the models currently available at EMIN, which are easy to select, easy to use, and suitable for various purposes
