3 Types Of pH Level Testing For Lawn
A soil pH test evaluates how many hydrogen ions are in the soil. There are three types of pH level testing. These include dye soil pH testers, soil pH test strips, and electronic soil pH testers. Soil pH is defined as the alkalinity or acidity of the soil on a scale of 0 to 14. A pH result showing less than 7 is acidic, while 7 is neutral and higher than 7 is alkaline.
The article discusses the most commonly used pH level tests. Also, where can you find different pH level tests, factors to consider before purchasing one, its cost and if there is a DIY pH level testing kit. So, let’s start with the three types of soil pH level tests.
1. Colored Dye Soil pH Testers
In the colored dye pH test, the colored dyes are combined with the soil water to give you results of pH levels and Phosphorus, Nitrogen, and Potassium levels. The color obtained is compared to a supplied chart to determine the pH level.
2. Soil pH Test Strips
Soil pH test with a pH test strip is a simple indicator test requiring some soil, a clean cup or jar, water, and a pH test strip. Many test paper strips are universal and test from pH 1 to 14. This is fine; some, however, test a smaller range. Preferably, you need a test strip that includes pH from 4.5 to 10 for soil testing. The strips help determine a rough range that your soil’s pH is between. It is used to determine the pH value of any liquid, nitrogen in soil and nutrient solution.
There are certain drawbacks of using pH test strips. Most pH test strips that are available in the market are for the purpose of testing the full pH range from 0-14. With this broad testing pH range, you won’t be able to get an accurate reading. pH testing strips are for single use only, so you can not reuse the same strip. A fresh new strip must be used every time you need to perform a test.
If you want to do regular pH testing as part of your gardening monitoring routine, you will use a number of these pH test strips, which will add up in cost over time. You need good lighting when performing the test, as the results are based on matching the test strips to a color chart. pH test strips are quite affordable. A box of 100 pH strips will cost you around $15 to $25.
3. Electronic Soil pH Testers
Electronic soil pH testers are easy-to-use devices that measure the acidity or alkalinity of the soil. It consists of a probe inserted into the soil water, and the pH can be read directly from the display. Cheap models are available with a metallic probe, and the instructions say that you insert this directly into the soil.
When you measure soil pH directly from the ground, there is a risk of damaging the spear/electrode. Also, the results are usually less accurate. However, measurement with soil solution is more time consuming than the direct ground measurement approach. An electronic soil pH tester will cost you anywhere between $10 to $200 depending on the quality.
Which Type Of pH Level Test Is The Most Commonly Used?
Electronic pH meters are the most accurate and commonly used type of measurement for performing pH level tests. These pocket-sized testers are easy to use devices for fieldwork and are fairly low cost.
Where Can We Find Different Types Of pH Level Tests?
Different types of pH level tests are commonly used therefore are easily available in the market as well as you can purchase them online.
What Factors Should Be Considered Before Purchasing pH Level Test?
It is important to know how to take a pH test for lawn. There are five essential factors as enlisted below
- Accuracy: The accuracy of meters lies in the range of ±0.1 pH to ±0.001 pH. For example, a pH meter with an accuracy of ±0.01 is suitable for quality control or research environments.
- Calibration: Consider buying a meter that uses at least a 2-point calibration and calibrate as near your expected result.
- Electrode: When deciding to purchase from available pH meters, consider the cost of replacing electrodes as they are relatively fragile, and it is probable you will need their replacement over the life of your meter.
- Temperature: pH readings are affected by temperature. The pH meter should be calibrated at the same temperature as a sample to achieve an accurate reading..
- Portability: Consider where you are going to use your pH meter, in the field or lab. For a highly portable pH Meter, consider a handheld or pocket meter.
How Much Does A pH Level Test Cost?
Almost all the pH level tests are affordable and cost between $5 to $200. The cost also depends on the quality of pH level test you are purchasing.
