Fields outlined in trees when seen from above
The most limiting factor to crop growth in soil is drainage. Therefore, most fields have a network of drainage tiles within them and those tiles channel water to ditches that are along the sides of the fields. As fields are taken out of production, these ditches will fill with volunteer trees that will eventually plug up the ditches.
