The Water Table-Negative
The water level in this diagram is called the water table. Trees take up huge amounts of water, so the water table stays low. However, when the trees are removed, the water table rises. This brings dissolved salts closer to the surface. Crops can't handle
lower water level, negative, less trees, worse crops, absorbs salt
