Which of the following statements is/are true? Statement A: Soil testing provides valuable information about nutrient levels, pH, and other soil properties. Statement B: Soil samples should be collected randomly from different areas of the field for accurate soil testing. Statement C: Soil testing is unnecessary if the plants are showing visible signs of nutrient deficiencies.

Soil testing is a valuable tool for assessing soil fertility. It provides information about nutrient levels, pH, organic matter content, and other soil properties, helping to guide nutrient management decisions and optimize fertilizer applications. To obtain accurate soil testing results, soil samples should be collected randomly from different areas of the field. This ensures representative sampling and accounts for potential spatial variations in soil fertility within the field. Soil testing provides quantitative data on nutrient levels, pH, and other soil parameters, helping to diagnose deficiencies accurately and tailor nutrient applications to specific crop needs.
