Planting Day! We planted the sand hill with our dry land mix. The whole process took the good portion of the day, but the seeds are officially in the ground. Here is the process (thanks Julia Brokaw for the pictures):
1. Cultipack - we drove over once with the cultipacker to make sure that the ground was firm. One of the biggest risks to prairie seeds is that they are too deep, so we first packed the soil to make sure that they don't get driven in too deeply in the soft, sandy soil.
Our dry site is just over 8 acres, but the farmer accidentally put a bit (about 2 acres) of it into corn (just kept driving out of habit). It isn't a problem, because you can plant prairie seeds in the fall. We held some back until the corn comes off. It will probably be better to have some diverse planting plans anyway, because different plants will respond differently.
We made one pass over everything with the oats, spreading them pretty thick. We then added all the prairie seeds to the hopper, and re-calibrated it to account for the smaller seeds.
