Soil Texture Triangle Calculator
Soil Texture Triangle Calculator is an intelligent and interactive tool based on the USDA soil classification system. It enables users to quickly and accurately identify the soil texture category by entering the percentage composition of clay, silt, and sand. The tool is ideal for users seeking data-driven insights into soil properties, supporting better decisions in crop selection, irrigation planning, and soil management.
What is a Soil Texture Triangle?
The Soil Texture Triangle is a widely recognized graphical model used to classify soil types. The calculation is based on the relative percentages of the three major mineral components: sand, silt, and clay. It is divided into 12 standardized texture classes, including Clay, Loam, Sandy Loam, Silty Clay Loam, and others. Each zone within the triangle corresponds to a distinct soil behavior profile that influences key characteristics such as water retention capacity, drainage, nutrient availability, aeration, and workability. The triangle allows users to determine the soil texture class visually or computationally based on where the input percentages intersect. Moreover, it helps users to visually understand how to make a target soil texture.
How to Use This Tool
- Enter Values: Input the percentage of clay, silt, and sand. The sum of the three types’ percent must be exactly 100% for a valid result.
- Click “Generate”: The tool will calculate the coordinates and automatically highlight the corresponding texture class on the triangle diagram.
- View Result: The identified region will be visually emphasized, and the soil texture class name is marked as the result in the triangle diagram.
By simplifying the complex process of soil texture classification, this calculator enhances accessibility to soil science for users of all backgrounds. It is an essential resource for integrating soil analysis into practical agricultural or ecological planning.
