Cuphea nitrogen uptake and seed yield response to nitrogen fertilization
Cuphea (Cuphea viscosissima Jacq. x C. lanceolata W.T. Aiton, PSR23) is an oilseed crop that is a rich source of medium-chain fatty acids. Progress has been made on improving cuphea agronomically, but little is known about N fertility requirements for optimum cuphea production. The objective of this study was to determine the N necessary for maximizing seed yield and oil content. Experiment 1 was ...

Will variable-rate nitrogen fertilization using corn canopy reflectance sensing deliver environmental benefits?
Within-field variability of corn (Zea mays L.) N need calls for development of precision fertilizer application strategies. One approach many are investigating is in-season canopy reflectance sensing. Justification for this strategy partly rests with the premise it will improve N use and reduce N loss from fields. The objective of this study was to determine the potential environmental benefits ...

How seed-placed fertilizer may hurt your crops if not applied carefully and attentively
Placing fertilizer within the seed row has been long-standing practice for many farmers across the prairies. Having those nutrients close to the seed makes it easily accessible by the plant, and can help the crop out of the ground and into the sun. Potash fertilizers and other nutrients, such as phosphate, are immobile fertilizers, meaning they don’t travel more than a half-inch through ...
