Growing Nitrogen in Orchard Is Focus of Field Tour

QUINCY, Wash. – Field-scale trials of four different perennial legumes seeded in orchard alleys to fix nitrogen will be on display during a field tour being organized by Washington State University’s Center for Sustaining Agriculture and Natural Resources.

The field tour will take place on Tuesday, Aug. 11, from 4 to 5:30 p.m., at Warren Morgan Orchards in Quincy. The orchard is located on Road 9 N.W., just west of Road V N.W.

Speakers will discuss how the trial is being conducted along with current results, the potential to use legumes to “grow” nitrogen in the orchard, and the implications for pest biocontrol from interplanting legumes.
