I consider myself to be a very good forage agronomist — I can design and manage a pasture that will produce an eye-popping amount of very nutritious forage. My failings as a rancher, on the other hand, have included failing to keep cattle where they needed to be, not putting the water where the feed was, and other practical matters of pasture management that I never considered quite as interesting as the plants themselves. But these matters are just as important, if not more so, as the plants and their management.
Livestock can survive without food far longer than they can survive without water, and the most nutritious plants in the world do you no good if your animals are loose on the other side of your fence.
