Interactive effects of landscape position and time of application on the response of spring wheat to fall-banded urea
The objective of this experiment was to quantify the effect of landscape position and time of application on the agronomic efficiency of fall-banded urea [CO(NH2)2] for spring wheat (Triticum aestivum L.) grown in the eastern prairie region of Canada. Landscape positions in this experiment were defined as high and low based on their relative elevations to one another within the field. Fertilizer ...
