Transpiration response of two bread wheat lines differing in drought resilience and their backcross parent under dry-down conditions Open
Improving wheat productivity in drylands largely depends on how plants manage limited water resources. Using fraction of transpirable soil water threshold (FTSWTh) and drought stress response function, we characterized the water…

Cosmic-ray neutron probes on the high plains of Nebraska: applications to large scale agriculture Open
Cosmic-rays have some surprising applications in precision agriculture. The cosmic-ray neutron probe (CRNP), when implemented as a roving instrument, can be used to create spatial maps of soil moisture, and from these maps soil hydraulic p…

Estimation of Biomass Water Equivalent via the Cosmic Ray Neutron Sensor Open
The CRNS functions at its most fundamental level as a detector of the hydrogen within its area of influence (circle of radius ~ 250 m). As such, hydrogen other than that within the water molecules in the soil is detected. A series of calib…
