Today’s high yielding hybrids and increasing population densities have researchers once again looking at the quantity and timing of nutrient uptake throughout the growing season. Each macro and micronutrient has a unique role and individual characteristics within the growing plant. Having the right rate at the right time can definitely influence the performance of high yielding hybrids.
Researchers from Purdue University and University of Illinois are focusing on this topic to determine if new fertility guidelines are required. The results of these studies have exemplified the need for greater fertility to maximize yields. Their findings provide an interesting insight as to when, where and how nutrients are taken up and ultimately partitioned.
