Chemical Agricuture 202: Monoculture - Limited Crop Rotation

A monoculture is the human agricultural practice of growing a single species crop over a wide area and for many consecutive years. The most common monoculture is field corn, where millions of acres per year are grown and sometimes in the same place for many years.

At face value this would seem very efficient as specialized corn planting and harvesting equipment can allow one farmer to grow thousands of acres per year. However the monoculture has a dark side which we will explore in this post.

Chemical Agriculture 200: Elucidation

When I was in high school I was the poster child for modern chemical agriculture. I grew up on a chemical agriculture farm and spent the first 25 years of my life being "educated" by a system that brought us the "green revolution" and I don't mean recycling. I was FFA (Future Farmers of America) chapter president for three years and took 4 years of Ag training while in high school. I was an avid reader (still am) and read every book I could get my hands on how to grow corn, soybeans, oats, sorghum, alfalfa, and clover.

I also studied livestock husbandry. I wrote a 50 page thesis on bacterial diseases of livestock for my high school biology class. I was so interested in this that I borrowed all the books our local veterinary (a recent graduate of Iowa State University) had on bacteriology, biology, and livestock diseases. I read them cover to cover and then asked if I could use his micro scopes, centrifuge, stains and antibiotic sensitivity disks to identify various livestock bacteria. What newly minted PhD in veterinary science could turn down such a wannabe disciple. He and I had a great time my sophomore year in high school reviewing the basics of veterinary bacteriology. Looking back on it was probably a good review for him too. He was a very talented surgeon and was very good at diagnosing problems. By the time I was off to college I had inoculated and vaccinated thousands of head of livestock (on our farm) for various common and minor maladies.

I share this with the reader so you understand I'm not just an organic zealot (yes I am that), but I understand the other side of the coin pretty well.

Elucidation is a verb meaning to explain and make a subject that is hard to understand clear or easy to understand. The root of the word is from the Latin "lucid" to make clear. Let's look deeper...

Chemical Agriculture 102 - Insects and Pesticide

In our last discussion on Chemical Agriculture we learned that plants on chemical nutrients like Miracle Grow in the garden or corn in the field, look really lush and nice to our narrow vision of the spectrum.

To the insect pests this rapid uptake of highly soluble nutrients makes the plants look out of balance and sick. The insects both good and bad have antenna arrays in their bodies that are sensitive far outside the visual spectrum into the infrared.

To these pests the large corn field mono-culture screams, I'm sick, I'm unhealthy, I'm out of balance.
