Here are a few random ag-related photos that I thought might be interesting.
We went to the field yesterday, and the cattle thought we were there to feed them.
Actually, we were there to mark soil sampling sites for tomorrow's lab.
Meet Dr. Joe Kemble. He's on my committee. He's watering in lettuce seeds into "oasis cubes". They are made of pumice stone and are used for hydroponics.
One seed per cube.
This is a shaker. Here, I'm extracting some nutrients (specifically nitrate and ammonium) from some soil samples using 2 molar KCl. The clear tubes you see are blanks.
After extracting the samples, they are filtered. The filtrate is later analyzed using microplates. Tedious work, but better than studying for prelims!

I bet you are enjoying the lab and field work after being stuck at your desk for the last month studying. Lettuce grown in pumice, huh? Maybe we can grow food on Mars!
That looks intriguing. That experiment looks v. interesting
Man. That's some serious Lettuce Growing going on there.
