Nitrogen Source Study on Potatoes

IPNI-2005-USA-MD12

Rotation: White Potatoes, Wheat/Doublecropped Soybeans, Grain Corn and Single Crop Soybeans. Note: The experiment is set up so each crop will be evaluated each year. Example of a Rotation Cycle: Notill and Zoned Tilled grain corn, Notill and Minimum Tilled Soybeans, Conventional Tilled(chisel plowing/discing) White Potatoes planted into the continuos notill and minimum tilled strips, Notill/Minimum Tilled Wheat/Double Cropped Soybeans.

Nitrogen Source Study on Potatoes, 2006 This project was carried out in the 2006 growing season, with potatoes in no-till and minimum tillage cropping systems. The objective was to compare N sources varying in proportion of ammonium sulfate. No yield benefit was observed as a result of including ammonium sulfate in a blend of ammonium nitrate and calcium nitrate as an N source.
