Benefits of soil pH testing kit

There are many things you will learn from testing your soil pH.

Know your pH levels

The first and most obvious benefit of soil pH testing is the fact that you will easily know the pH of your soil. This will help you understand what nutrients your soil will absorb easily.

In many cases, the soil has the right nutrients.

However, because there pH levels are either too low or too high, these nutrients are not readily available to plants.

The pH of your soil acts as a highway for nutrients to reach your plants.

Testing your pH tells you whether it is right to plant and which food groups can thrive in the condition.

Know the presence of toxic metals

If you are planting in an urban setting, you need to be very keen on whether the soil has been exposed to any toxic metals.

While growing your own food is healthy and great in every way, the presence of heavy metals in the soil is a cause for concern.

If you find toxic metals are available in the soil in high levels, you may have to perform remedial procedures to get the soil back to a neutral state.

You need to check and ensure that local and state authorities approve of remedial procedures to be used.

Know the amount of  fertilizer to apply

With soil testing, you get to know the micro-nutrient requirements for your crops.

In many cases, you find that if you apply too much fertilizer, your crops are burnt. In turn you get low yields or no yields at all.

Too much fertilizer will also waste your time and money. If you do not apply enough fertilizer, you will also end up with low returns.

Knowing just how much fertilizer to apply saves you a lot of time and money.

In addition you get a higher yield, better quality and plants that mature better and faster.

The crops you grow will also fight off pests and diseases easily.

You can choose to take samples all over you garden randomly. However, it is always best to take the samples through the different cultivation levels and types.

You should also have an aim of how many samples will be enough for you to accurately test every area of your farm.

Ensure that you have labeled each sample individually. This will allow you to know where the samples come from.

3. How to collect the soil

When getting the sample, ensure that you have scrapes away the two top inches of soil.

This is to ensure that the sample is not contaminated by top dressings and any mulches that maybe on the soil.

Take the sample once you have attained a depth of about five inches. After all, the plant roots will be beyond five inches deep.

After you have collected the sample, prepare it for testing by removing any twigs and rocks.

It is also important that you let the sample to dry in room temperature for a few hours.

4. Carry out the test

Once the soil is dry, pick it up with a clean dry spoon and place it in a test tube.

The type of soil test you carry out will depend on the type of test you have bought.

There are both liquid and powder based test kits. While they all perform the same job, they are performed differently.

For the liquid test, put it the liquid as instructed by the manufacturer, shake the test tube and leave it to settle for ten minute before you take your reading.

For the powder based kits, ensure that you put in the instructed amount of distilled water, mix well with the soil and let it settle for ten minutes.
