What tool is commonly used to determine soil texture in the field?

• A. Soil moisture meter
• B. Soil texture triangle
• C. Hydrometer
• D. Pore tester

Answer: (B)

The soil texture triangle is a fundamental tool for determining soil texture in the field because it visually represents the relationships between sand, silt, and clay proportions in a soil sample. By measuring the percentage of each particle size, a soil judge can plot these values on the triangle to classify the soil into specific texture categories such as sandy, clayey, loamy, or silty. This classification is crucial for understanding soil behavior, fertility, and suitability for various land uses. In contrast, the other tools listed serve different purposes. A soil moisture meter measures the moisture content in soil, which provides insights into water availability but does not determine texture. A hydrometer is used to measure the specific gravity of soil particles in a suspension, often in a lab setting, rather than in the field. A pore tester evaluates the pore spaces within the soil but does not classify soil texture directly. Thus, the soil texture triangle is the most appropriate and practical tool for this specific task.
