Planting the same crops in the same field without rotation.
Over-irrigating until the soil just follow the water right out the fields.
Deep plowing that exposes the topsoil to winds.

1. Increased use of annual crops (crops that are only grown for one season) in the crop rotation. For example corn-soybean-wheat has higher soil erosion than alfalfa-wheat. Alfalfa keeps the soil protected from the wind during the winter time and the soil is not exposed to rain and wind as much.

2. Plowing - This turns the surface of the ground over so that the soil is exposed to the wind and rain.

3. Harvesting the whole plant of the crop. For example when you harvest corn for grain, you leave the stalks behind in the field to protect the soil. When you harvest corn for corn silage, you remove the entire plant, exposing a lot more ground.
