“…The experiment was a randomized complete-block design with four replications of five N rates. A second set of four replications, previously under a conventional moldboard plow tillage winter wheat-fallow rotation (Albrecht et al, 2005), was established 30 ft north of NTA in 1997 as winter wheat-fallow under no-till (NTB) (Rasmussen & Albrecht, 1998) before being converted in fall 2010 to a winter wheat-winter pea (W-P) cover crop (Gollany et al, 2021). Both phases of the rotation were present every year.…”

Cover cropping with legumes such as winter peas under dryland winter wheat production systems has several benefits that could improve the resiliency of production systems and agroecosystem services. This article demonstrates the use of winter pea cover crops to increase winter wheat yields in the intermediate (12–16 inch) rainfall zone and to improve drought resiliency.

“…The USDA-ARS in Pendleton (Pendleton), OR, provided soils and data from a longterm experiment at the Columbia Plateau Conservation Research Center exploring winter wheat response to tillage, cover crops and nutrient management [31]. Here, we analyzed one soil core per strip (2 × 34 m) per treatment.…”

Can Agricultural Management Induced Changes in Soil Organic Carbon Be Detected Using Mid-Infrared Spectroscopy?

A major limitation to building credible soil carbon sequestration programs is the cost of measuring soil carbon change. Diffuse reflectance spectroscopy (DRS) is considered a viable low-cost alternative to traditional laboratory analysis of soil organic carbon (SOC). While numerous studies have shown that DRS can produce accurate and precise estimates of SOC across landscapes, whether DRS can detect subtle management induced changes in SOC at a given site has not been resolved. Here, we leverage archived soil samples from seven long-term research trials in the U.S. to test this question using mid infrared (MIR) spectroscopy coupled with the USDA-NRCS Kellogg Soil Survey Laboratory MIR spectral library. Overall, MIR-based estimates of SOC%, with samples scanned on a secondary instrument, were excellent with the root mean square error ranging from 0.10 to 0.33% across the seven sites. In all but two instances, the same statistically significant (p < 0.10) management effect was found using both the lab-based SOC% and MIR estimated SOC% data. Despite some additional uncertainty, primarily in the form of bias, these results suggest that large existing MIR spectral libraries can be operationalized in other laboratories for successful carbon monitoring.
