Title: Usefulness of Irrigation Water and Fertigation as Nitrogen Sources for Potatoes
Principle Investigator: K.A. Kelling / UW-Madison, Soil Science
Objective: To compare the relative use efficiency of fertigation-applied N through overhead sprinklers or drip irrigation compared to conventional banding prior to row closure.
Funding Level: $15,760, $15,760, $15,760
Duration: 3 years (ongoing)
Title: Development of a Variable Rate Nitrogen Application Approach for Corn
Principle Investigator: L.G. Bundy / UW-Madison, Soil Science
Objective: To evaluate within-field variation of optimum N rates for corn in uniformly managed fields typical of those used for corn production in Wisconsin.
