Soil Texture Calculator
Determine the USDA soil texture class based on the percentage of sand, silt, and clay.
How to Use the Soil Texture Calculator
- Enter the sand percentage (%).
- Enter the silt percentage (%).
- Enter the clay percentage (%).
- Verify the sum equals 100% and click Calculate.
Casi d'Uso
- •Identifying texture class from soil analysis results.
- •Planning irrigation and drainage systems.
- •Agrochemical characterization of land.
- •Educational and research purposes in soil science.
Formula
Sand + silt + clay = 100%. Texture class is determined using the USDA soil texture triangle based on the fraction percentages.
Domande Frequenti
Why must the fractions sum to 100%?
The three fractions — sand, silt, and clay — make up 100% of the mineral portion of soil. The total must equal 100%.
How do I determine the soil fractions?
Use the hydrometer or pipette method in a laboratory, or approximate using the field texture feel test.
Why is texture class important?
Texture determines water permeability, water-holding capacity, aeration, and suitability for different crops.
