The soil sample submitted for testing will be analyzed for which of the following?

• A. Soil pH, phosphorus, potassium, magnesium, and calcium levels
• B. Presence of pesticides
• C. Microorganism levels
• D. Cadmium, zinc, and PCBs

Answer: (A)

In garden soil testing, the key goal is to know how available nutrients are to plants and whether the soil pH is in the right range for nutrient uptake. A typical soil test reports the soil’s pH and the levels of essential macronutrients—phosphorus, potassium, magnesium, and calcium. These results directly guide lime and fertilizer decisions, since pH affects how well nutrients dissolve and are absorbed by roots, and because adequate levels of these nutrients support root development, growth, and overall plant health. Other items like pesticides, microbial counts, or specific heavy metals require separate, specialized tests and aren’t part of a standard nutrient-fertility panel, which is why the common soil analysis focuses on pH and those major nutrient levels.
