What can be inferred from the analysis of two soil samples?

The correct choice emphasizes that different soils possess varying nutrient compositions, which is crucial for understanding soil health and its suitability for plant growth. Analyzing soil samples allows for identification of the nutrients present, such as nitrogen, phosphorus, potassium, and various micronutrients.

This information is vital as it indicates that soil types can significantly differ in their fertility and support for plant life, impacting agricultural practices and environmental science. Knowing that different soils contain different nutrients helps in making informed decisions about crop selection and land management practices to optimize plant health and yield.

The other options, while potentially related to soil analysis, do not capture the broader implications of nutrient diversity indicated in the question. They speak to specific conditions or assumptions without addressing the fundamental concept of nutritional variability between different soils. This variance in nutrient composition ultimately guides best practices in agriculture and ecology.
