All nutrients are needed at varying levels to grow your best crop, it’s a proven fact. Historically nitrogen is the nutrient that demands the most attention, but you could be wasting your current input investment if the crop doesn’t have the right balanced nutrition, limiting yield and quality potential. Micronutrients, although needed in much smaller quantities, are just as essential as macronutrients.
Without balanced nutrition, yield loss is inevitable, as depicted here. You could increase your nitrogen rate to try to prevent loss, but if the other nutrients aren’t also provided to the crop the increased nitrogen won't have an impact on yield. Crop yield is limited by the element in least supply.
Many critical components of crop performance depend on micronutrients; such as root development, good plant membrane and structure, green leaves and healthy canopy, even flowering and more. Micronutrients also play a role in the utilization of other nutrients like N and P. Don’t sacrifice your crop’s potential by skipping an easy step of adding micros to your fertility program.
With every crop grown, there are nutrients that are taken up that directly correlate with yield. The nutrients need to be supplied to crops when the soil doesn’t deliver them, as is the reality across Western Canada where nutrient deficiencies are prominent. You have to give back what your previous crop took for continued success and to maximize your yield potential.
