Cause and Effect.

So the soil around the sprinkler tracks where I disked in January warmed up faster this spring, resulting in faster germination and emergence of the corn I planted. Here are some photos from throughout the spring and summer:





It of course became the most pronounced during pollination.
The slow emergence under no-till is what a lot of people don't like about it (And so they practice strip-till) but this year, at least, I was glad to see the rest of the corn lag behind those strips. The corn in those strips pollinated with high temperatures between 100-105 F (that's bad.) The rest of the field pollinated a few days later with highs between 85-90 F (that's good.)
