What is the optimum ph value for plant growth?

The most suitable ph for plant growth is generally between 5.2 and 6.8.

PH value is an index to measure the ion concentration in soil, which will affect the absorption of mineral ions by plants, thus affecting the osmotic pressure of plant roots, and may cause plants to lose water and wither or even wither. It will also affect the species and quantity of microorganisms in the soil.

Plants in acidic soil (pH < 6.5), alkaline soil plants (pH > 7.5) and neutral soil plants (pH
