Personally I find agronomy to be a rather boring science, but someone has to study all the ways we can make crop production more efficient.

Humans have been farming since the dawn of time, but agronomy made farming much easier for people in the past few hundred centuries.

Different fertilizers are often produced by people that study agronomy, their research unearthing better ways to grow more crops.

For those that study agronomy, discovering new ways to mitigate the effects of soil erosion is a major part of what they do.

I decided against studying agronomy in college, since I really had no interest in dirt or anything in particular that grows in dirt.
