For healthy plant growth, having the correct pH is essential. It is also important to be aware of the long-term effects of various activities of soil management on soil pH.

What is pH?

Soil pH is an acidity or alkalinity indicator of the soil.

A pH value is also a calculation of the concentration of hydrogen ions. Because of the vector hydrogen ion concentration, a logarithmic dimension (pH) is used: the acidity increases by a factor of 10 with a pH decline of 1 (1).

Importance of pH Levels

The right soil pH is one of the essential factors in growing a healthy garden, but it is often ignored in favor of soil and nutrient levels. Although these are all important factors to remember, the soil’s pH plays a vital role in how well the nutrients you supply your plants absorb. 

Sometimes the incorrect application of soil pH does not entirely kill plants, but it may affect growth and produce subpar blooms or cultures, depending on the crop’s sensitivity. Many plants are currently able to tolerate a variety of pH levels. 

Plant toxicity is the darker side of soil pH. The pH level of manganese in plants can be too low and accessible for toxic use; Geraniums that display irritation with yellowed, brown-stained, or dead leaves are especially vulnerable to this. Aluminum—not a plant nutrient—is also released at too low a pH level into quantities, impeding the root’s growth and preventing the plant from absorbing nutrients. At a high pH level, molybdenum is available in toxic amounts as a plant nutrient.

Soil pH also affects soil-induced species, the well-being of which in turn affects soil and plant health. Earthworms, just as microorganisms turn Nitrogen into plant types, often prefer the slightly acidic conditions of most plants.

When the pH of your plants is changed, don’t delete the pH from your mind. It is an ongoing job to maintain the correct pH level of your soil, particularly in normal, acidic eastern and northwest soils in which precipitation releases calcium and other alkaline compounds. 

Alkaline soils will naturally continue to change the pH level due to their rock minerals. In certain situations, it is challenging to acidify these soils. Due to materials such as ammonium sulfate and ammonium nitrogen, even fertilizers can alter their soil pH over time by moving down pH and potassium nitrate or calcium upwards.
