Pendleton Wheat-Pea Rotation Experiment

This experiment has been added by the GLTEN Curators using existing published sources.
Local identifier
WP
Years operational
1963—
Objective
To evaluates the timing and severity of tillage operations on the soil and wheat and pea productivity.
Description
Given observed declines in SOM it was hypothesized that annual cropping using wheat and peas in rotation under reduced tillage would improve soil productivity compared to the annual mono-cropping of wheat under conventional tillage.
