Soil Texture Calculator

Enter the sand and clay percentages from your soil test to identify USDA texture class. Texture shapes how your soil holds water, cycles nutrients, and responds to regenerative management.

Texture Classification

Loam

USDA

A well-balanced mix of sand, silt, and clay. Loam soils are generally considered ideal for crop production.

Regenerative Insight

Loam soils respond well to cover cropping and reduced tillage, building organic matter steadily over time.

Why texture matters

Texture is the foundation of soil behavior — it governs drainage, water-holding capacity, aeration, and how readily nutrients become plant-available.

/ 02

How to get your numbers

Sand and clay percentages come from a lab soil test or a jar-sedimentation test. Most regional ag labs report these on every standard analysis.

Texture is durable

Unlike organic matter or nutrients, texture does not meaningfully change over a human timescale. Management should work with your texture, not against it.
