These tally with a hand-drawn map of the claypan

layers; demonstration of deep-ripping equipment.
It is also concentrated along the Michigan peninsula, in central Wisconsin and Minnesota, in the claypan
soils of eastern Texas, and on the tablelands of central Nebraska.
While few other crops can grow in the poorly draining claypan
of the Sacramento River floodplain, the packed soil holds the water that rice roots in, and--combined with the valley's temperate climate--creates nearly perfect growing conditions for rice.
