Question

What is the best soil pH for most plants?

Answer 1

Soil:

1. It is a naturally occurring material that is composed of minerals and organic constituents and rich in nutrients and minerals for plant growth and nourishment.
2. It is distinguished on the basis of the horizon of variable depth, material morphology, composition, physical, chemical, and biological properties.

pH:

1. It indicates the acidic and basic nature of the soil through ${\mathrm{H}}^{+}$ion concentration and ${\mathrm{OH}}^{-}$concentration.
2. The high amount of ${\mathrm{H}}^{+}$ion concentration shows the acidic nature of the soil and the high concentration of ${\mathrm{OH}}^{-}$indicated the basic nature of the soil.
3. The equal amount of ${\mathrm{H}}^{+}$ and ${\mathrm{OH}}^{-}$concentration show the neutral condition.

The best pH for the soil is:

1. The pH value for the soil is 6.5 to 7 because most of the nutrients are available for the crop.
2. When the pH value is less than 6 then the aluminum content increases which is toxic for the plants.
3. The activity of microorganisms affects due to the more acidic nature of the soil.
