Which Fertilizer Increases the Acidity of Soil?

Sulfur-based fertilizers are often a good choice for acidic soils, while nitrogen-based fertilizers may be more effective for neutral soils. Phosphorus-based fertilizers can also affect soil pH, so it’s essential to monitor soil pH and adjust fertilizer application rates accordingly.”

Top 5 Best Acidic Fertilizer 2026

Within this article, we will guide you through the process of choosing the best acidic fertilizer. We have employed extensive research and testing on various acidic fertilizers, analyzing their content, effect on plant health, and value for money.

Fertilizers are indispensable in agricultural production, providing essential nutrients for plants and promoting crop growth. There are various types of fertilizers, including organic, inorganic, and biofertilizers. The acidity or alkalinity of fertilizers significantly impacts crop growth. Below, we analyze the best acidic and alkaline fertilizers, along with their advantages and disadvantages.

I. What Are Acidic and Alkaline Fertilizers? The acidity or alkalinity of fertilizers refers to their chemical components' ability to release hydrogen ions (H⁺) or hydroxide ions (OH⁻) when reacting with water. A neutral soil pH indicates balanced fertilizer acidity/alkalinity, while acidic or alkaline soil pH reflects specific properties of the fertilizer.

II. Which Fertilizers Are Best for Adding Acidicity?

1. Phosphates: Common acidic fertilizers that lower soil pH, benefiting acid-loving crops. excessive use may lead to soil acidification, harming other plants. Example: Superphosphate or ammonium phosphate.

2. Ammonium Sulfate: An acidic fertilizer that releases hydrogen ions, enhancing nitrogen and sulfur supply while lowering soil pH.

3. Potassium Nitrate: Though primarily neutral, it can acidify soils over time due to nitrification processes.

III. Which Fertilizers Are Best for Adding Alkalinity?

1. Lime (Calcium Carbonate/Oxide): A potent alkaline fertilizer that raises soil pH, improving nutrient availability and soil structure. It also supplies calcium and magnesium.

2. Gypsum (Calcium Sulfate): Mildly alkaline, it corrects sodic soils by replacing sodium with calcium.

3. Potassium Silicate: Alkaline fertilizer providing potassium and silicon, beneficial for plant resistance and soil pH balance.

IV. Why Choose Acidic or Alkaline Fertilizers?

1. pH Balance: Plants require optimal pH for nutrient absorption. Adjusting soil acidity/alkalinity ensures healthy growth.
2. Nutrient Availability: Certain nutrients (e.g., iron, aluminum) become more soluble in acidic soils, while others (e.g., calcium, magnesium) thrive in alkaline conditions.
3. Soil Health: Long-term use of acidic/alkaline fertilizers prevents soil degradation, compaction, and toxicity from excess ions.

V. How to Use Acidic/Alkaline Fertilizers Effectively

1. Test Soil pH: Conduct soil tests to determine pH and nutrient needs before application.
2. Control Dosage: Avoid overapplication to prevent extreme pH shifts. Follow recommended rates.
3. Combine Fertilizers: Mix acidic and alkaline fertilizers to neutralize side effects while providing balanced nutrition.
4. Timing: Apply based on crop stages. For example, acidic fertilizers may suit early growth, while alkaline ones support flowering/fruiting.

Acidic and alkaline fertilizers offer distinct benefits but require careful selection. Lime, sulfur, and phosphates are key examples for adjusting pH, while balancing nutrient supply and soil health is crucial. Always prioritize soil testing and targeted application to maximize crop yields sustainably.
