1、Technical Bulletin: Fertilizers and Soil Acidity
Of all the major fertilizer nutrients, nitrogen is the main nutrient affecting soil pH, and soils can become more acidic or more alkaline depending on the type of nitrogen fertilizer used.
2、Fertilizers and Soil Acidity
– Intensive agriculture can speed up soil acidification through many processes – increasing leaching, addition of fertilizers, removal of produce and build-up of soil organic matter.
3、Soil pH Effects Potassium and Phosphorus Fertilizer
Low pH decreases the soil’s ability to keep supplying potassium to plants, therefore potentially increasing the need for additional fertilizer applications or liming to raise the soil pH.
Effect of fertilizers on Soil pH
Soil acidification can speed up if practices remove cations (like calcium and magnesium) from the soil – e.g., increased leaching due to irrigation, removal of nutrients in produce or addition of fertilizers.
Links between potassium of soil aggregates and pH levels in acidic
Soil pH adjusted by the application of lime can improve soil potassium (K) availability to meet crop K uptake in acidic red soil. However, the response of aggregated K to pH changes is poorly understood.
HOW DOES SOIL pH AFFECT FERTILIZERS AND FERTILITY
Certain fertilizers can also push the soil pH down. Uptake and subsequent removal through removal of plant materials such as pulling out annuals each year can have an acidifying effect on soils.
Potassium Rich Soil: Tips For Lowering Potassium Levels
Potassium is a critical nutrient that plants absorb from the soil, and from fertilizer. A little extra potassium generally isn’t cause for worry, but potassium-rich soil can be a problem. Click this article to learn how to reduce potassium in soil.

Chemical Fertilizers and Their Impact on Soil Health
Constant use of chemical fertilizer can alter the pH of soil, increase pests, acidification, and soil crust, which results in decreasing organic matter load, humus load, useful organisms, stunting plant growth, and even become responsible for the emission of greenhouse gases.
Reasons for Soil Acidification Caused by Excessive Potassium Fertilizer:
Excessive potassium fertilizer can lead to soil acidification because potassium ions in the soil may form sparingly soluble compounds with cations such as calcium and magnesium. This reduces the concentration of these cations in the soil, subsequently lowering the soil’s pH. Additionally, overapplication of potassium fertilizer accelerates the decomposition of organic matter, producing large amounts of acidic substances, which further intensifies soil acidification.
Solutions:
-
Reduce potassium fertilizer usage: Overuse of potassium fertilizer is a primary cause of soil acidification. Adjusting fertilization strategies, controlling potassium dosage, or substituting with alternative fertilizers are critical steps.
-
Increase organic fertilizer application: Organic fertilizers rich in organic matter and trace elements improve soil structure and buffering capacity, mitigating acidification. Combining organic fertilizers with other nutrients can enhance soil resilience.
-
Boost soil organic matter content: Organic matter strengthens soil buffering ability and water retention. Practices like planting green manure crops or straw incorporation can increase organic matter levels.
-
Regularly monitor soil pH: Frequent testing of soil acidity helps track acidification trends and enables timely intervention.
-
Use soil amendments rationally: Amendments (e.g., lime, gypsum) improve soil structure and buffering capacity. Select locally appropriate amendments for optimal results.
-
Avoid excessive acidic fertilizers: Limit the use of acidic fertilizers (e.g., sulfur powder, ammonium sulfate), as they accelerate soil acidification.
-
Enhance soil management: Adopt practices like proper tillage, crop rotation, and balanced irrigation to prevent acidification.
-
Improve soil microbial activity: Higher microbial activity promotes efficient organic matter decomposition, reducing acid production. Increase organic inputs and optimize soil conditions to boost microbial populations.
-
Select acid-tolerant plant species: Planting species resistant to acidity minimizes the impact of soil acidification.
-
Seek professional guidance: For severe acidification, consult agricultural experts to develop tailored remediation plans.
