What is the primary focus of soil toxicity analysis?

The primary focus of soil toxicity analysis is to determine the potential for plant toxicity. This involves assessing the presence of harmful substances in the soil that could negatively affect plant growth and health. Toxic elements or compounds, such as heavy metals, pesticides, or industrial contaminants, can hinder plant development or even lead to plant death. By identifying these toxicants, soil toxicity analysis enables farmers, agronomists, and environmental scientists to make informed decisions on soil management practices and crop selection, ensuring healthy plants and sustainable agricultural practices.

Other options touch on important aspects of soil analysis, such as moisture levels, erosion potential, and microbial activity, but they do not directly address the core purpose of toxicity analysis, which is specifically centered around evaluating the risks posed by contaminants in the soil to plant life.
