Soil pH is a measure of how acidic, neutral, or alkaline the soil is. It is measured on a scale of 0 to 14, where a pH of 7 is neutral, values below 7 indicate acidic soil, and values above 7 indicate alkaline soil. Soil pH plays a crucial role in determining nutrient availability, microbial activity, and overall plant growth.

Soil pH Range

• Below 7: Acidic soil

• 7: Neutral soil

• Above 7: Alkaline soil

Why is Soil pH Important?

• Influences the availability of essential nutrients

• Affects root growth and nutrient absorption

• Supports beneficial soil microorganisms

• Impacts crop health and yield

Ideal Soil pH for Most Crops

Most crops grow best in slightly acidic to neutral soil, with a pH range of 6.0 to 7.5. However, some crops prefer more acidic or alkaline conditions depending on their specific requirements.

How to Manage Soil pH

• Add lime to raise the pH of acidic soils.

• Apply sulfur or organic matter to lower the pH of alkaline soils.

• Test soil regularly to maintain the ideal pH for your crops.

Maintaining the right soil pH helps improve nutrient uptake, promotes healthy plant growth, and leads to better crop productivity.
