  • Nitrogen recommendations based on crop reflectance

    Nitrogen fertilizer is usually applied in greater quantities to corn than almost any other crop. But when it’s applied in excess of requirements, loss of the excess fertilizer to the environment can contribute to degraded water quality. One of the challenges to making an appropriate nitrogen fertilizer recommendation is the potential variability in soil nitrogen availability that may occur ...

  • Corn colour can tell farmers how much fertilizer to apply

    Nitrogen fertilizer is a key ingredient for growing a good corn crop. It is not unusual for a well-fertilized crop to yield more than twice as much as an unfertilized crop. But how much nitrogen should corn producers apply to their crop? Researchers at the University of Missouri help answer this question in a study of how much light is reflected from corn plants reported in the May–June issue of ...
