Soil Texture Triangle Calculator
The same method can be used starting on any side of the soil triangle.
Soil texture triangle calculator. Soil texture triangle hydraulic properties calculator. For example sand particles are much larger than clay particles. Nb you do not need to enter values for silt because these are calculated from the clay sand figures. By understanding the texture of the soil we know the soil type.
With this in mind soil texture charts can be illustrated as a triangle. Including the optional sand fractions will refine the calculation. Reading a soil texture chart. Larger particles will have less surface area per volume of soil.
This program estimates soil water tension conductivity and water holding capability based on the soil texture organic matter gravel content salinity and compaction. The texture of soil refers to the size of the soil particles. The soil triangle is a commonly used visual representation of the possible soil type combinations based on soil particle size. Calculate to obtain the soil properties for the respective texture.
The usda classifies soil types according to a soil texture triangle chart which gives names to various combinations of clay sand and silt. Or download a microsoft excel macro enabled spreadsheet to develop total sand silt and clay low representative and high values using an interactive texture triangle with textures that toggle on and off. 1 read the definitions below. Use this online tool to calculate a single point texture class based on percent sand silt and clay.
Sand particles range from 0 05 to 2 0 mm silt particles are between 0 002 and 0 05 mm in diameter while clay particles are less than 0 002 mm in size. Or download a microsoft excel macro enabled spreadsheet to develop total sand silt and clay low representative and high values using an interactive texture triangle with textures that toggle on and off. Chemical and physical properties of a soil are related to texture. Use this online tool to calculate a single point texture class based on percent sand silt and clay.
The estimator is based on the texture class intervals of the soil survey of england and wales note that other international standards also exist such as the usda and fao triangles. Each side of the triangle represents the amount of an ingredient. Soil water characteristics hydraulic properties calculator. Here is a tool that allows you to estimate the particle size class of a soil sample from the proportions of sand silt and clay.
If the texture by feel method was used to determine the soil type the triangle can also provide a rough estimate on the percentages of sand silt and clay in the soil.
