PPM (Parts Per Million) is a unit of measurement used to express the concentration of nutrients, chemicals, or other substances in soil, water, or fertilizers. It is commonly used in agriculture to manage nutrient levels with precision.
PPM Explained in Simple Terms
1 PPM = 1 mg of substance per liter (mg/L) of water
1 PPM = 1 mg of substance per kg of soil
For example:
➡️ 1 gram of fertilizer dissolved in 1000 liters of water = 1 PPM
