    • Introduction to the Function and Application of this Calculator

The Soil Texture Calculator is a powerful tool designed to simplify the process of determining the soil texture class and its associated hydraulic properties. By inputting the percentage of clay and sand in your soil sample, this calculator provides precise estimations based on the USDA Soil Texture Triangle, a widely recognized classification system in soil science. Whether you are a researcher, farmer, or environmentalist, understanding soil texture is crucial for optimizing plant growth, improving water management, and assessing soil health. This tool helps users make informed decisions in agriculture, landscaping, and environmental monitoring.

    • Explanation of Input Parameters

The Soil Texture Calculator relies on two key input parameters to deliver accurate results:

  • Clay (%): This value represents the percentage of clay particles in the soil. Clay particles are the smallest soil particles, measuring less than 0.002 mm in diameter. A higher clay percentage often indicates soils with higher water retention but slower drainage. You can learn more about soil particle sizes from University of Nebraska's soil texture guide.
  • Sand (%): This value denotes the percentage of sand particles in the soil. Sand particles are the largest, ranging in size from 0.05 mm to 2 mm. Soils with a higher sand percentage are typically well-draining but may have lower water-holding capacity.

By entering these two parameters, the calculator uses the USDA Soil Texture Triangle to classify the soil into one of 12 texture classes, such as sandy loam, silty clay, or loamy sand.


    • Explanation of Output Parameters

Once the input values are provided, the Soil Texture Calculator generates a detailed analysis of the soil's physical and hydraulic properties. The output parameters include:

  • Soil Texture: The classification of the soil based on the USDA Soil Texture Triangle.
  • Bulk Density (kg/m3): A measure of soil compaction, indicating the mass of soil per unit volume.
  • Field Capacity (mm/m): The amount of water the soil can retain after excess water has drained, measured in millimeters per meter.
  • Wilting Point (mm/m): The minimum soil moisture level at which plants can no longer extract water.
  • Porosity (%): The percentage of the soil's volume that is occupied by air or water, reflecting its ability to retain water and air.
  • Hydraulic Conductivity (mm/hr): The rate at which water flows through soil, measured in millimeters per hour.

These outputs provide users with actionable insights into their soil's ability to support plant growth, retain water, and facilitate drainage.
