Nutrient Management

Examples of corn K deficiency across different soil test K levels (A = 76 ppm, B = 103 ppm, and C = 127 ppm). These images highlight the importance of building soil test K to critical concentrations and maintaining levels within the optimum range to reduce deficiency risk and the likelihood of yield response to fertilization.
