Soil pH and method for its adjustment:

Soil pH and method for its adjustment are being listed here first of all we have to know what is soil pH?

What is pH of soil?

We always see agricultural experts talking about the pH of the soil, which is also called the pH of the soil.

Which is an indicator of the degree of alkalinity or acidity of the soil. It is acidic, and any number higher than 7 is considered alkaline or sugary.


The importance of the pH of soil:

Technically, the pH is a measure of the hydrogen ion concentration in any substance, and you as a farmer need to know if your soil is alkaline or acidic.

Because there are certain nutrients in the soil that can only reach the plant if the pH or alkalinity in the soil reaches a certain amount.

If the pH factor is not appropriate, then any fertilizer you will use will benefit the plant only after adjusting the pH of the soil to a degree suitable for the plant.

Most plants prefer a somewhat neutral pH, which is between 6.2 and 7 on the pH index, but there are plants that require special degrees of pH.

Such as blueberries , which need high-acid soil, or lilac plants that need more alkaline soil.

A plant like the hydrangea changes the color of its flowers according to the change in the level of pH in the soil.

In general, if you find that your plants are growing healthily and without problems, this is a sign that the pH of the soil is within an acceptable range.

But if the plants are stressed, have changed the color of their leaves, or are not growing normally, then you should do a pH test in the soil.

How do you know the pH of your soil?

When it comes to measuring the pH of your soil, you have some options.

There are many meters that are sold in garden centers and you can use them yourself.

Most of these measurements give good results that help you make appropriate soil adjustments.

But if you want more accurate results, you can send soil samples to a lab for analysis.

But if you only want to know if your soil tends to be alkaline or acidic, use a home test.

How do you modify the pH of the soil?

Adjusting the pH of the soil takes months and needs constant work, and if you leave the soil for a while it will return to its natural pH on its own.

If your soil is not highly alkaline or acidic you will not need to amend it completely, but only adjust the areas where you grow plants that need a pH Different .

Basically, lime is used to adjust the pH of acidic soil, while alkaline soil sulfur is used to amend it.

The amount depends on the current pH of the soil, the current soil texture (sandy, clay, or humus) and the type of plants grown in it.

Once you get the reasonable pH of the soil, you will need to use lime or sulfur again at regular intervals to maintain the acidity you want.

It is best to do this in the autumn season so that the soil has enough time to slowly amend without damaging the roots of the plants.

It is a good idea to re-test Soil every 3 years to see if it needs to be modified again.

Of course, plants are the main indicator. If they grow well, there is no need for any amendments.
