What happens if the pH of the soil is too low or too high?
A pH reading that is too high or low will lead to a loss of these microorganisms, which will result in a less healthy soil overall. In addition, pH affects the solubility and potency of certain toxic chemicals, such as aluminum, which can be taken up by plants if the pH is off.
How does alkaline soil affect plant growth?
Alkalinity impairs plant growth by restricting water supply to the roots, thus obstructing root development. It results to phosphorus and zinc deficiencies, and possibly iron deficiency and boron toxicity. Plants have less ability to extract essential nutrients from the soil when damaged by alkalinity.
What causes high alkalinity in soil?
Alkaline Soils Soils may be alkaline due to over-liming acidic soils. Also, alkaline irrigation waters may cause soil alkalinity and this is treatable, but alkaline soils are primarily caused by a calcium carbonate-rich parent material weathering (developing) in an arid or dry environment.
What can happen if the pH of soil is above 7?
Increase in Toxicity Most plant nutrients are at their most available state at a pH of 6.0 to 6.5. At a higher pH, soil builds up toxic levels of certain nutrients. For example, molybdenum, typically a plant nutrient, becomes poisonous to plants in large amounts.
What is Alkaline Soil?
The pH scale runs from 0 to 14. Most soil sits somewhere from 3-10. Acidic soil is anything lower than 7.
Why is pH important for gardening?
Understanding soil pH is an important part of the gardening puzzle. pH affects the amount of available nutrients in the soil that roots can absorb. When soil is highly alkaline or highly acidic, it reduces the nutrients available to plants. Alkaline soil is less soluble than acidic or neutral soil.
How to make your garden soil more acidic?
2. Amend with Peat Moss. Another option is to add peat moss to your soil.

Ferrous sulfate adds iron to the soil and helps plants that have yellowing leaves and overall poor health.
How to lower pH in soil?
One of the best (and easiest) ways to increase acidity (and lower pH) in the soil is to add sulfur. Most garden nurseries sell garden sulfur in the area with compost or fertilizers. Add one to three ounces of ground rock sulfur per one square yard of soil. Doing this lowers the pH level to appropriate levels.
Why is hard water more likely to be alkaline?
Watering soil with hard water also increases the chances of alkaline soil because hard water contains lime. Pure water has a pH range of 7, but most water sources take on bits of the surrounding environment, so the pH varies by region.
What Makes Soil Alkaline?
There are many reasons for soil alkalinity. Humans, as well as nature, are responsible for increasing the pH value of soils. Let’s discuss these.
How to reduce alkaline soil pH?
One of the best ways to reduce the alkaline nature of the soil is by adding sulfur. Adding about 1-3 grams of ground rock sulfur to 9 square feet (1 square yard) can reduce soil pH by one. Soil bacteria convert sulfur into sulfuric acid, which helps reduce the pH level.
What is the best way to reduce soil pH?
Fertilizers. Fertilizers that use an acidifying nitrogen source are used to increase the soil pH levels. Ammonia or urea-based fertilizers are an excellent way of reducing soil pH. These kinds of acidifying fertilizers contain ammonium sulfate, diammonium, and mono ammonium phosphate.
What is the pH of soil?
Soil pH value that is greater than 7 is deemed alkaline soil. A pH scale is divided from 1 to 14. Here, 1 is the most acidic, 7 is neutral, and 14 is the most alkaline. Alkaline soil falls between the pH value of 7 and 14 on the pH scale. A lot of farmers call such soil ‘sweet soil’.
How to test soil pH without a lab?
A simple way of soil testing is using cider vinegar. Put a few drops of cider vinegar on the soil sample. If it fizzes, then your soil pH is alkaline in nature.
What makes compost acidic?

What pH is the best for decomposition?
The enzymes that break down organic material operate best within a pH range of 5-8, but severely acidic or alkaline soils break down these enzymes, which brings decomposition to a halt. The decomposition process is what turns organic material into organic matter; a huge influencer on soil structure.
How does nitrogen help plants?
You are adding nitrogen to the soil, and then relying on the enzymes within the soil to transform it into nutrients that your plants will use. There are hundreds of enzymes involved in transforming inert vitamins and minerals into forms that your plants can absorb and use.
What is the pH of a soil?
The pH scale ranges between 0 and 14, where pH 7 is neutral, pH values below 7 are acidic, and pH values above 7 are alkaline. The lower the pH value, the more acidic the soil, and conversely, the higher higher the pH value, the more alkaline the soil.
What crops grow best in acidic soil?

What pH is compost?
Organic manure or compost is close to neutral 6.5 to 7 pH so using it in your soil brings the pH up to neutral. Compost also helps different types of soil as well. It helps sandy soil retain more water, helps plant roots spread better by loosening tightly bound clay or silt soil particles, and helps prevent soil erosion.
What is the pH of a soil?
The pH scale ranges from 0 to 14, with 6.5 to 7 being a neutral pH. Different plants prefer different soil pH which, therefore, requires a particular balance in soil nutrients. While some plants prefer acidic soil, it can be a problem if the soil you have is too acidic.
Why add aluminum sulfate to soil?
Think about adding aluminum sulfate. This compound instantly makes the soil more acidic due to a chemical reaction involving aluminum. Because of this, many amateur and small-scale gardeners prefer aluminum sulfate to organic compounds or plain sulfur. However, because it alters the pH of the soil so quickly, it can be more difficult to control the soil acidity.
