Soil Texture Triangle Calculator

This calculator helps you determine the soil texture class based on the USDA soil texture triangle. Enter the percentages of sand, silt, and clay to get the texture classification of your soil sample.

Result

Your soil texture class will appear here.

Data Source and Methodology

All calculations are based on the USDA soil texture triangle. Refer to the official guide for more details. All calculations are strictly based on the formulas and data provided by this source.

The Formula Explained

Using the soil texture triangle, the soil class is determined by plotting the sand, silt, and clay percentages.

Glossary of Terms

  • Sand: Particles between 0.05 mm and 2 mm in diameter.
  • Silt: Particles between 0.002 mm and 0.05 mm in diameter.
  • Clay: Particles smaller than 0.002 mm in diameter.

How It Works: A Practical Example

Suppose a soil sample contains 40% sand, 40% silt, and 20% clay. By plotting these values on the soil texture triangle, the texture class is identified as a 'loam'.

Frequently Asked Questions (FAQ)

What is a Soil Texture Triangle?

A soil texture triangle is a tool used to classify the texture class of soil based on the percentages of sand, silt, and clay it contains.

Why is soil texture important?

Soil texture affects water retention, nutrient availability, and root penetration, influencing plant growth and soil management practices.
