This is the third post in a blog series focused on improving nitrogen (N) use efficiency in California small grains. This post discusses two hand-held devices that indicate plant N levels in small grains to help optimize fertilizer decisions. The tools help determine plant vigor by measuring light reflected from the whole plant canopy or absorbed by a single leaf. Comparing measurements made in and immediately outside of N rich zones in representative areas of the field helps determine if the crop is likely to respond to more N fertilizer. The plant N levels indicated by the hand-held devices complement other important information, which are...
