If you are someone who has been doing farming or gardening since long or even if you are a beginner, then you might now the importance of soil pH. The pH of the soil is the level that determines the acidity or alkalinity of it. Range of pH is from 0 to 14, in which 0-7 is the pH for acids and 7-14 range is for bases or alkalis. The pH of 7 is neutral, which is also the pH of water. There are many factors of soil that affect the crop yield and well-being of the plants. Apart from soil fertility, porosity and texture, the pH of the soil also plays a vital role in plant growth.
Generally, the plants require pH in the range of 6-7 for optimal growth. This criteria differs from plants to plants. Berries need alkaline soil, whereas lilies require soil with a little acidity. Before growing plants, it is essential to go through its requirement for soil pH, water requirement and much more. So once you know the optimal pH suitable for your plant, you can increase or decrease the pH accordingly.
How to Raise ph in Soil with Baking Soda?
In this article, we will particularly focus on the ways to increase the pH of soil. There are many chemicals and compounds available in the market that can aid in increasing the soil’s pH. But the most cost-effective and quick way to do so is to use baking soda. Unlike other commercial products, it is easily available in your kitchen and doesn’t harm the soil. To raise the soil pH with baking soda, follow the step-by-step procedure given below:
Test the soil pH
The first and foremost step is to know the current pH of your soil. For doing this test, you will need a soil test kit and tiller. Collect a soil sample and do the test as per the instructions. You can also send a sample of the soil to the lab if you want the complete analysis of the soil sample.
Do the analysis and determine the amount of baking soda you will need?
Once you are done with the test, wait for its results to decide the further procedure. If the pH levels are lower than the required range only then opt out for increasing it. Note down this value for your record and comparing it after adding the soda to the soil.
Add Baking soda to the soil.
Now that you know the level of pH, you can decide the quantity of baking soda. Generally, one tablespoon of baking soda is required for one gallon of water. Keep this proportion in mind while making the mixture. Take soda and mix it with water properly. Once the solution is ready, add it to the soil. Some people also add baking soda directly to the soil but mixing it with water is more preferable.
Water the soil regularly.
After you have added the baking soda to the soil, it is essential to water the soil normally as you would do. Follow the schedule for watering to get the optimal results.
Check the level of pH after some weeks.
For checking if the baking soda is helping with increasing the pH, recheck the levels after a couple of days. Take a soil sample and test its pH level. If the pH is in the range of your requirements, then you can stop adding more soda to the soil. Continue adding fertilizers and water. Monitor the pH levels and add the soda when there is a decrease in the pH.
Baking soda is effective in raising pH levels of the soil. In case you want to try the other alternatives for increasing the levels, then you can also opt for limestone. Also here is a little tip if you want to decrease the pH level then replace baking soda with vinegar.
