RE: Scouting cotton with EIR

[Sarah Morgan <sarah_morgan@xxxxxxxx>]

Barry,
I am currently doing my thesis on taking small plot photographs from approx
10 feet high using EIR film and comparing them to aerial photos of the
entire research field.  I am photographing forages with various Nitrogen
rates and have had a hard time working out the logistitcs of small plot
photography.  Getting high enough isn't the problem but focusing the picture
at the desired height has provided opportunity for much invention.  I am
currently working with a 10 foot ladder and a monopod clamped to the top
extended out over the plot area.  I am still having trouble with the angles
and focusing logistics and my first set of photos primarily involved me
leaning over the the plot with someone steadying the ladder.  If you come up
with any better ideas please contact me as I will do the same.

Cheers and No Worries,

Subject: Scouting cotton with EIR


After a couple of tornadoes, a hail storm, a sand storm, and 10
inches of rain (all in 5 days), we had a sizeable percentage of our
cotton crop that was severely damaged or dead. As part of our effort
to distinguish between the damaged cotton and the dead cotton, we did
on-the-ground spot checks with EIR a week after the storm to see
where we could see plant activity. Sure enough, areas that looked
similar to the naked eye looked very different to EIR, and the areas
showing more IR reflectance have since greened up.

I'm familiar with using aerial and sattelite IR imagery to asses crop
condition, but am not familiar with any work being done at the plant
and plat level. Can anyone direct me to references that might help us
make this a regular part of our scouting regimen?
