Fertilizers containing ammonium nitrate, ammonium sulfate, or sulfur-coated urea can increase the acidity of the soil very quickly. So just look for Ammonium-based fertilizers on the pack.

Choosing the Right Fertilizer for Acidic Soils

Soil acidity is a common challenge faced by gardeners, farmers, and landscapers around the world. Acidic soils, typically defined as having a pH below 6.0, can significantly impact plant growth, nutrient availability, and overall soil health. Selecting the right fertilizer for acidic soils is crucial to improving crop yields, maintaining soil fertility, and ensuring sustainable land management ...

Soil pH balance is critical for plant growth. In agricultural production, adjusting soil pH to optimal levels (pH value) is essential to ensure healthy crop development. Below are common methods to adjust soil pH and achieve balance:

1. Applying Lime (CaO)

• Lime is one of the most widely used agents for regulating soil pH. It reacts with acidic substances in the soil to form soluble calcium salts, thereby raising the pH.
• Dosage: 10–15 grams per liter of soil, depending on initial and target pH.
• Application: Dissolve lime in water, then evenly spread or incorporate it into the soil.
• Caution: Excessive use may disrupt soil structure and cause nutrient leaching.

2. Applying Sulfur (S)

• Sulfur, an organic matter-based agent, reacts with soil acids to form sulfates, lowering the pH.
• Dosage: 3–5 grams per liter of soil, adjusted based on pH targets.
• Application: Mix sulfur with water and distribute uniformly.
• Caution: Overuse may harm microbial activity and plant growth.

3. Applying Organic Fertilizers

• Organic fertilizers (e.g., compost, green manure) improve soil pH through biochemical processes.
• Dosage: 1–2 kilograms per liter of soil, tailored to pH needs.
• Application: Mix with water and apply evenly.
• Caution: Excessive use may negatively impact microbes and plants.

4. Applying Acidic Fertilizers

• Acidic fertilizers (e.g., ammonium sulfate, ammonium nitrate) react with alkaline soil components to form soluble salts, reducing pH.
• Dosage: 0.5–1 kilogram per liter of soil, based on pH goals.
• Application: Combine with water and spread uniformly.
• Caution: Overapplication may harm soil microlife and plant health.

5. Applying Alkaline Fertilizers

• Alkaline fertilizers (e.g., calcium chloride, sodium carbonate) neutralize soil acids to raise pH.
• Dosage: 1–2 kilograms per liter of soil, depending on pH requirements.
• Application: Mix with water and incorporate into the soil.
• Caution: Excessive use may disrupt microbial balance and plant growth.

6. Applying Phosphate Fertilizers

• Phosphate fertilizers (e.g., superphosphate, triple superphosphate) react with alkaline soils to form soluble salts, lowering pH.
• Dosage: 0.5–1 kilogram per liter of soil, adjusted for pH targets.
• Application: Combine with water and distribute evenly.
• Caution: Overuse may inhibit microbial activity and plant development.

7. Applying Micronutrient Fertilizers

• Micronutrient fertilizers (e.g., boric acid, ammonium molybdate) influence soil pH via chemical reactions.
• Dosage: 0.01–0.05 kilogram per liter of soil, based on pH needs.
• Application: Mix with water and apply uniformly.
• Caution: Excessive use may harm plants.

8. Applying Organic-Inorganic Complex Fertilizers

• Organic-inorganic blends (e.g., humic acid, alginic acid) improve pH through chemical interactions.
• Dosage: 0.01–0.05 kilogram per liter of soil, adjusted for pH balance.
• Application: Mix with water and spread evenly.
• Caution: Overapplication may disrupt plant growth.

9. Regular Soil pH Testing

• Testing: Use strips, pH meters, or professional equipment to monitor soil pH regularly.
• Adjustment: Modify fertilization strategies based on results. If soil is overly acidic or alkaline, apply appropriate regulators.

In Summary

These methods effectively adjust soil pH to create optimal growth conditions. crop-specific pH requirements, growth stages, and soil conditions must be considered when formulating fertilization plans. Follow principles of appropriate dosage, timing, and application to avoid nutrient imbalances and environmental pollution.
