Yesterday was quite a day.
It was my turn to give a lecture on a topic of my choice in my Advanced Soils class. I chose allelopathy: an interference mechanism used by plants to affect other plants by releasing chemicals into their surrounding environment. Or if you'd prefer: plant chemical warfare! :) It went well and tomorrow we will be discussing three case studies I chose for the class to read. All this work is helping me with my comprehensive exam, so I am really feeling great about how things are progressing.
After my class presentation, I went straight to the soil lab and continued to run my aggregate stability samples. I am testing the stability of 2mm sized soil aggregates (clumps of individual soil particles held together by organic matter and other materials).
By testing the stability of the aggregates we are assessing how vulnerable the soil is to water erosion. If they break apart easily then they are very vulnerable to erosion, but if they are stable then the soil is less vulnerable and has a higher quality. Anyway, I have been working my way through 40 samples of soil with the wonderful help of my lab assistant (each sample takes anywhere between 30-60 min, just for the stability test). After the initial stability test, we then have to rinse the stable aggregates into a tin that we put in the oven over night (or longer) until the sample is oven dry. After it is dry, we then weigh it. This whole process is pretty involved and has taken quite a bit of time...BUT yesterday I FINISHED IT! :) All the samples have now been tested and are drying - so they just need to be weighed. SO EXCITING.
Immediately after I finished the last aggregate stability test, I rushed off to meet a friend at the pool. We swam and talked. It was fabulous. I am loving that I have reincorporated swimming into my schedule! Plus, I get to touch base with my friend while doing it, so it makes it that much better!
After swimming, I came home with a big smile. What a day. Everything felt like it just clicked into place! I even arrived and left at the same time as the stranger I parked next to! How crazy is that. There were two open parking spots and we pulled in at the same time and then, as I was rushing to the pool, he was also walking to his car from the opposite direction...then we got in our cars and left at the same time. Can't say that happens too often...unless you're being stalked I guess...and that wouldn't be good.
Today had a hard time living up to the standards that yesterday set, but I was still fairly productive! Also, the sun came out today. It's warmth felt nice and made for a pleasant walk to and from class.
