What is the main purpose of soil testing in nutrient management?

• A. To determine planting dates
• B. To analyze soil structure
• C. To provide nutrient recommendations
• D. To assess crop yield potential

Answer: (C)

The main purpose of soil testing in nutrient management is to provide nutrient recommendations tailored to the specific needs of the soil and the crops being grown. By analyzing the nutrient levels present in the soil, testing helps farmers and land managers understand what nutrients are available and which may be lacking. This information is critical in informing the application of fertilizers and other soil amendments to optimize plant growth and yield, while also minimizing the risk of over-application and environmental impact. Soil testing assesses key factors such as pH, organic matter content, and the concentrations of essential nutrients like nitrogen, phosphorus, and potassium. This data ensures that any nutrient management plans are evidence-based and cater to the unique requirements of the soil type and crop variety, ultimately supporting sustainable agricultural practices and improving productivity.
