Early Detection of Nitrogen Deficiency in Corn

Overview

Take measurements of a nitrogen test plot in corn. Develop better understanding of photosynthesis response to nitrogen deficiency. Begin gathering base research to use the photosynq device as a tool for choosing side dress nitrogen application rates.

Protocols

Leaf Photosynthesis - MultispeQ Beta ONLY

Measures photosynthesis-related parameters in <15 seconds, including: Phi2, PhiNPQ, PhiNO, NPQt, qL, LEF, and SPAD. In addition, measures PAR (photosynthetically active radiation), ambient temperature and relative humidity.

Works with the MultispeQ Beta device only
