Soil Texture Calculator

The Soil Texture Calculator is for calculating soil texture, which includes an online soil texture calculator, mobile applications, and manual methods. Such calculators provide a convenient way to determine the texture of a soil sample based on the percentages of sand, silt, and clay it contains.

These calculators are valuable tools for farmers, agronomists, and soil scientists in making accurate assessments of soil types. Let us find out online Soil Texture Calculator and its benefits.

What is Soil Texture?

Soil texture is an essential factor in agricultural success, influencing plant growth and productivity. Understanding soil texture is crucial for farmers and agricultural professionals to make informed decisions about soil management and crop selection.

Soil texture refers to the composition of the soil in terms of its mineral particles. It includes sand, silt, and clay, and it is important as it directly affects plant growth and the ability of the soil to retain nutrients and water. The proportions of these three particle sizes determine the texture class of the soil.

The USDA, which stands for the United States Department of Agriculture, has a way of categorizing different types of soil based on the size of the particles in them.

Imagine soil as a mix of tiny pieces, like grains of sand. Now, the USDA looks at how big these pieces are.

  • First, there's clay. Clay particles are super tiny, even smaller than the other types. They're less than 0.002 millimeters wide. Clay feels very smooth and sticky when wet.
  • Next up is silt. Silt particles are a bit bigger than clay but still pretty small. They're between 0.002 and 0.05 millimeters wide. Silt feels smooth but not as sticky as clay.
  • Lastly, there's sand. Sand particles are the biggest of the three. They range from 0.05 to 2 millimeters wide. Sand feels gritty and rough.

So, when the USDA talks about soil, they might say it's mostly clay, or it has a mix of sand and silt. This helps farmers and scientists understand what kind of soil they're dealing with and how best to use it for growing plants.

How to Determine Soil Texture Manually?

To determine the texture of soil quickly, especially for fish-pond construction where soil with a high proportion of silt and/or clay is preferred, you can perform a simple test called the "throw-the-ball" test and Squeeze-the-Ball Test. Here's how you do it.

Test 1- Throw the Ball Test

To determine the texture of soil using the "Throw the Ball Test" test, follow these steps.

  1. Get Some Soil: Take a handful of moist soil from the area you want to test.
  2. Squeeze into a Ball: Squeeze the soil in your hand to form a ball. Make sure the soil is moist enough to stick together.
  3. Throw the Ball: Now, throw the ball of soil into the air to a height of about 50 centimeters (or about 20 inches).
  4. Observe: Pay attention to what happens when you catch the ball:
    • If the ball falls apart easily when you catch it, as it crumbles into pieces, it means the soil likely has too much sand. This suggests poor soil quality for holding water well.
    • If the ball sticks together when you catch it, holding its shape without breaking apart much, it indicates that the soil probably contains a good amount of clay. This suggests the soil is better for holding water, which is beneficial for fish ponds.

This test gives you a quick idea of the soil texture at different depths and can help determine if the soil is suitable for your intended use, such as constructing a fish pond.

Test 2- Squeeze-the-Ball Test

To determine the texture of soil using the "squeeze-the-ball" test, follow these steps

  1. Get Some Soil: Take a handful of soil from the area you want to test.
  2. Moisten the Soil: Wet the soil slightly so that it becomes damp but not dripping wet. You want it to stick together but not stick to your hand.
  3. Squeeze the Soil: Squeeze the soil in your hand as hard as you can, forming it into a ball.
  4. Release: Open your hand and let the soil fall out.
  5. Observe: Pay attention to what happens:
    • If the soil retains the shape of your hand, meaning it holds together in a ball even after you release your hand, it indicates that there is probably enough clay in the soil. This suggests that the soil might be suitable for building a fish pond because clay helps hold water well.
    • If the soil crumbles and does not retain the shape of your hand, it suggests that there is too much sand in the soil. This indicates poor soil quality for building a fish pond because sandy soil doesn't hold water as effectively.

By performing this simple test, you can quickly assess the texture of the soil and determine if it is suitable for your fish pond construction project.

Soil Texture Formula

Soil Structure Formula in simpler terms.

Soil Structure Formula: S=(AX+BY+CZ)​/100

Here's what each part means:

  • S is the soil composition.
  • A, B, and C are the percentages of each soil component (sand, silt, and clay).
  • X, Y, and Z are the corresponding values of each soil component in the soil triangle.

How to Use the Formula

  1. Collect Percentages
    • Get the percentages of sand (A), silt (B), and clay (C) in your soil sample.
  2. Refer to Soil Triangle
    • Look at a soil triangle to find the corresponding values (X, Y, and Z) for sand, silt, and clay percentages.
  3. Plug in Values
    • Substitute the values into the formula: (S=AX+BY+CZ)​/100
  4. Calculate
    • Perform the multiplication and addition, then divide by 100 to get the final soil composition percentage (S).

What is a Soil Texture Triangle?

A soil texture triangle is a graphical tool used in soil science to determine and classify the texture of soil based on its percentage of sand, silt, and clay. It consists of a triangular diagram where each corner represents one of these three soil particles.

Soil samples are analyzed to determine the percentage of each particle size, and the results are then plotted on the triangle to identify the soil texture classification, such as sandy loam, clayey silt, or other combinations.

This tool helps farmers, agronomists, and soil scientists understand the physical characteristics of the soil, which is crucial for managing and improving soil quality for various agricultural purposes.
