My twelve-year-old daughter is not a farmer. (Which probably does not come as a surprise to you!)
Last night, when she was studying for a biology test, she asked me to quiz her on some terms. Crop rotation was one of them.
"What is crop rotation?" I asked.
She thought about that for a second. "It's when corn spins around in circles and gets dizzy. Like when you're on a merry-go-round."
Corn gets dizzy from spinning? Right.
"No," I said. "It's when you rotate between crops to conserve nutrients in the soil - like soybeans and corn."
"Oh." She said. "So that means you spin in circles between corn crops and soy bean crops until you get so dizzy you fall down. Then you get buried and become fertilizer. And that's how more nutrients get put into the soil."
Yeah. Something like that.
