What is the difference between “direct, low-standing stubble” and “direct, high-standing stubble” harvest options?

This distinction refers to the height of the crop remaining in the field after harvest, not the type of equipment used. For example, some growers harvest close to the ground, leaving less than 10 inches of standing stalks (low-standing stubble). Others leave taller standing stalks — sometimes over 30 inches — to provide wind protection or temporary wildlife habitat during the off-season.
