AN EYE ON N:CROP-SENSING SYSTEM MEASURES AND QUANTIFIES CROP HEALTH AND PROVIDES INSTANT RATE ADJUSTMENT WHEN COUPLED TO VARIABLE-RATE CONTROLLERS.

摘要

Like most farmers, Matt Helmke, who farms about 900 acres in partnership with his dad, Myron Helmke, near Clatonia, Nebraska, applies a portion of the nitrogen destined for corn production prior to planting. In his case, it amounts to about 60 poundsapplied with the planter. However, Helmke also believes that sidedress nitrogen provides an advantage in and of itself for improving yield, primarily because he is able to apply nutrients when the crop is actually determining its yield potential. Plus, it puts the nitrogen where it's needed, when it's needed, so plants aren't as likely to run out of nitrogen before the end of the growing season.
