I believe that there is benefit from allowing land to rest. But I don't believe I am going to change the rain fall on it. I may change the amount of water retained by changing managment practices.
If you increase the effective water retention in the soil is that not same as getting more rain?
I believe I understand your point, and if I do, I see this as a totally different line of thought than the author is trying to make.
It appears to be the purpose of the author to make a big leap and try to convince the reader that farming practices (or humans) can alter the weather pattern significantly. It is nothing but a new twist on the "man made" global warming theory. And by man made, I mean the theory is contribed fiction from a man's brain.
Water retention and rain are different. Both may increase plant growth, yes. But they are still different.
As far as water retention, if it rains or if I poor 1 inch of water on the ground, the ground retains something between 1 inches of water and nothing (complete loss). I will agree that I can likely have some varying effect on this by how I graze, work, rest, or neglect the ground.
However, by my farming practices, I cannot cause the clouds to release 1.5 or 2 or 3 inches of precipitation to fall from the atmosphere to the soil. That is rain. And the author is saying that my agricultural practices can cause an increase in rain or can cause a drought.

What is the pratical rotation during the growing season in different areas of america? How long before the forage shows visible regrowth in your area? Daily rotation is best in my area with the amount of moisture and type of grass we have. We have visible regrowth after 3 days eaten or mowed. I can rotate the cows thru the paddocks on average 4 times a year.
We may have regrowth 3 days, 3 months or right now 3 years.
On a side note:
How much of the earth's surface is exposed water and how much is dry land? Something over 70% of the earths surface is ocean, then consider all the lakes, rivers, ponds, creeks, sloughs, snow and ice covered poles. It is hard to believe that such a small percentage of the surface and even smaller percentage of moisuture (I bet far less than 0.01% of the atmospheric moisture that you could affect) will have a global impact on weather. And weather is a global phenomenon.
They author said nothing about wild ruminents which also shows some lack of thought or ignorance. Buffalo were only one species. What about every other animal that makes use of the praire? In the area or Arizona he chose, what about deer, antelope, elk, desert sheep, rabbits, mice, rats, locus, grass hoppers, birds, etc... These are still living in the desert. The number of animals the area contains is the number it will support. If it was lush, there would be higher numbers. It is not.
I see an agenda and lack of thought. I'll shut my trap.
