Good soil is one of the most important aspects of having a successful garden. Without good soil, your plants will struggle to grow and in some cases, they might not grow at all. Making soil more acidic can help certain plants not only grow but also strive.
Based on local geography, soils mineral content varies, which in return affects its acidity or alkalinity levels in the soil. This is measured on a pH scale, which allows people to conveniently determine the acidity on their soil. Based on the plants you are growing, you can then research the pH levels they need and test the levels in your soil, adjusting them as needed.

Before starting your garden, it is best to test the acidity levels in your soil. Different plants need more acidic levels, whereas others don’t need much acidity at all. Fortunately, you can use a pH test to determine how acidic your soil is.
The best time to test the acidity levels of your soil is in the fall. This will then give you plenty of time to adjust your soil if need be before you plant your garden.
When testing your soil, use a hand shovel to dig about four to six inches down to obtain a sample. Once you dig up a good chunk of soil, remove any rocks, sticks, and debris from the soil. In addition, you also want to break up any large clumps of soil.
In a large bowl, add around one cup of soil along with enough water to make it into the mud. Then, add 1/2 cup of vinegar and stir it into your mud. If your mud begins to foam, fizz, or make bubbles, your soil is alkaline.
If no bubbling occurs, repeat the process as you did above by making mud with one cup of soil. Then, add 1/2 cup of baking soda and stir it in your mud mixture. If the mud begins to fizz, bubble, or foam, your soil is acidic.
Using A pH Testing Kit
You can also test the soil using a soil pH testing kit. This will give you an exact number of acidic your soil is. The pH test works on a scale of 0-14.
To use a pH testing kit, dig up soil from four to six inches down and remove any rocks and debris. Then, place one to three teaspoons of soil in a clean glass. Pour distilled water into the glass to the same level of the soil.
Shake the mixture well into it becomes well combined and then let it sit for 30 minutes. Then pour your soil sample through a coffee filter, collecting the water into a new clean glass. Be certain to get as much liquid out of it as you can.
Then place the pH strip into the liquid you collected and leave it in their according to the package’s instructions. Once it has been in the water for as long as it needed to be, compare the color of the strip to the chart of the package.
It is a good idea to repeat the process with samples from different parts of your garden. This will help you get a good idea of the average pH levels of the soil in your garden.
Why Acidity Levels Matter
Many plants thrive in acidic soil because the pH provides them with the nutrients they need to grow. In addition, pH levels in the soil also play a vital role in fertility. By having an ideal acidity level in your soil, the microbiological activity of the soil increases, which leads to improved soil nutrient recycling and release.
The pH levels in soil also work to maximize the nutrients of N, P, and K that come from fertilizers. Many plants will do best with a pH level that is right in the middle of the scale, however, it does vary by species of plant.
How To Make Soil More Acidic
Fortunately, if your soil is not acidic enough for your plant’s needs, there are several ways you can increase the acidity levels. Before adjusting your soil’s acidity, make sure to test multiple areas of your soil to find the average pH level of your garden.
One of the easiest and most effective ways for how to increase soil acidity is by composting. Since compost is rich in organic matter, it makes your soil more acidic gradually over time, which creates the most benefits for your plants. In addition, it not only improves the structure of the soil but also creates additional benefits for plant growth.
In addition, you can also use compost tea to increase acidity. Simply add one to two cups of your compost to one to two gallons of water. Allow it to sit for 48 hours, stirring regularly, then strain the compost and spray the liquid in your soil for fast-acting nutrients.
You can also use organic mulch, coffee grounds, and peat moss to help increase the acidity levels in your soil. In addition, you can also buy soil acidifier at gardening and department stores that is not only easy to use but also effective at improving the pH levels in your garden. However, it can be more expensive than the other options.
What increases the acidity in the soil?
There are several factors that can affect soil acidity, for example:
The amount of nitrogen in the soil. The higher the nitrogen content, the more acidic the soil will be. The type of soil. Soil with clay in it tends to be more acidic than soil with sand in it. Soil with a high calcium carbonate content (found in chalk) tends to be less acidic than soil with a lower calcium carbonate content.
You will increase the acidity of soil if you use any type of chemical fertiliser. This has nothing to do with what kind of chemical it is or how much it contains, but rather whether you have used a nitrogen, phosphorus and potassium containing chemical or not.
How is acidity measured?
Soil pH is measured on a scale from 0 to 14, where 2.0 is neutral, and below 3.0 is acidic and above 4.0 is alkaline.
The most common way to test your soil for pH is with a soil testing kit, or with an inexpensive test kit that you can buy at the grocery store or hardware store. To determine if your soil is acidic or alkaline, you can do this with the following procedure:
1. Fill a bucket with water, and mix in 2 teaspoons of salt per gallon of water.
2. Stir the soil thoroughly with your hands, and then add it to the water.
3. Allow the mixture to sit for 5 minutes, and then test the pH with a pH meter.
4. Record the pH of your soil on a pH chart, and then calculate the percentage of acidity
If the soil is more acidic than 5 percent, add 1 tablespoon of lime per quart of soil to increase the pH.
If the soil is more acidic than 15 percent, add 1 teaspoon of sulfur per quart of soil to increase the pH.
What should I do when my soil has too much acidity?
You should add some neutralizing agent to the soil. One way to do this is to add lime. Lime is an alkaline compound, so it will neutralize the acidity of your soil.
How do I fertilize acidic soil?
The best way to fertilize acidic soils is to use a compost tea that has been produced from compost. The compost will have a high pH and therefore the compost tea will also be high in pH. This means that it will be good at neutralizing acidity.
What is the most widely used way of making soil more acidic?
There are a number of ways you can acidify your soil.
Two of the most common: Lime and Wood Ashes. These are often recommended as “natural” methods for acidifying soils, but they should be used as little as possible as they are highly toxic.
Lime is an inorganic source of calcium carbonate. The lime reacts with water and releases carbon dioxide gas (CO2).
The benefits of adding lime are that it increases soil pH, improves drainage, and improves soil structure. It also helps to increase organic matter and nutrient content. The disadvantages are that it can cause high levels of soil salinity, and can be detrimental to some plant species (especially those that like a slightly alkaline soil). It should be noted that lime is not a fertilizer, but rather an acidifying agent.
Improving Your Soil: Making Soil More Acidic
Knowing how to make soil acidic can help improve the growth of the plants in your garden. It can provide your plants with the important nutrients they need in order to thrive.
Before planting your garden, it is a good idea to test the pH levels of your soil in several places to determine if your soil needs more acidity. In addition, be sure to research the plants you are going to add to your garden to find out what pH levels those specific plants require.
Compost is a great way to improve the acidity of your soil. In addition, you can also use compost tea, mulch, peat moss, and coffee to improve acidity. You can even buy soil acidifier from stores to help enhance your soil.
