[0002] Soil is a naturally occurring substance on the earth's land surface, composed of minerals, organic matter, water, air, and organisms. It is the basis for plant growth and an important component of terrestrial ecosystems. Soil testing refers to the process of analyzing and testing soil samples to understand the nature, composition, and contamination of the soil. Through soil testing, farmers and professionals can understand the true condition of the soil and take appropriate measures to improve soil quality, increase crop yields and quality, and protect the environment and human health. Before testing the soil, it is necessary to sample the soil using a soil testing sampler.
