Abstract EN
Little work has been done to characterize and quantify the residue traits affecting decomposition of winter and spring canola (Brassica napus L.) residue in dryland farming systems of the Pacific Northwest United States.
Traditional methods of characterizing residue fiber and nutrients are time-consuming and expensive and require large quantities of chemical reagents.
The goal of this research was to determine whether near-infrared spectroscopy (NIRS) could accurately predict neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent lignin (ADL), carbon (C), and nitrogen (N) of canola stems, litter, and roots and decomposition of canola stems.
Canola residue varied in decomposition, fiber, and nutrients by year, location, and type.
NIRS predictions were successful for NDF and ADF in 2011 (standard error of prediction SEP<2.67; R2>0.95) and NDF, ADF, and N in 2012 (SEP<2.38; R2>0.91).
Other predictions for residue fiber and nutrient characteristics were considered moderately successful.
Prediction of canola residue decomposition with NIRS was useful for screening purposes.
Near-infrared spectroscopy shows promise for rapidly and reproducibly predicting some canola residue fiber and nutrient traits and may be useful for estimating residue decomposition potential in dryland conservation cropping systems.
