What is the purpose of a soil tube?

The purpose of a soil tube is to obtain soil for testing. This tool is designed to extract a soil sample from the ground, allowing for analysis of its composition, structure, and other important characteristics. Collecting soil samples is essential for various purposes, including agricultural practices, environmental studies, and land management. By using a soil tube, users can gather soil from specific depths and locations, ensuring representative samples that reflect the actual conditions of the soil. This data is crucial for making informed decisions related to fertilization, planting, and soil health management.

The other choices, while related to soil analysis, do not accurately capture the primary function of a soil tube. Cutting soil relates more to tools like spades or augers, measuring moisture levels typically involves moisture meters, and checking pH levels is usually done using pH meters or test kits specifically designed for that purpose.
