Chew on this.

Meteor Crater

Meteor Crater

I took a trip with my wife and son a few years ago to the Grand Canyon. We went in March when the temperature was very nice and we had a great time. The Grand Canyon is beyond description. We saw some other local attractions like the San Francisco volcanic field and Meteor Crater. I had no idea there were so many actual volcanoes in the Southwest!

I had heard of Meteor Crater. My son was taking a College class on either Solar System Science or Interstellar Material at the University of Missouri at the time and we decided to tour the Crater since it was so topical to the class. Fascinating place to visit but I wouldn’t want to live there. It was very hot and dry most of the year.

One of the men at Meteor Crater got to talking about the surrounding ranch.The ranch runs cattle in the area and has for many years. The land doesn’t seem to have very much grass

Arizona Grazing land!

on it compared to good old Southwest Missouri pasture. If I remember correctly, he told us that the gazing supported about one cow for every thirty acres! That would be 1800 acres of “grassland” for the roughly 60 head of cattle we averaged on the farm where I grew up! This was quite a change in perspective from what I was used to.

 

This article from the University of Arizona gives a great in-depth description of of calculating the number of acres it takes to support a cow. Then you have to multiply the number of cows by that many acres to see how much grazing land you need to support a herd. Compare that to this article from the University of Missouri Extension office that says one beef cow and calf needs three acres per year in Southwest Missouri.

It just goes to show that Agriculture practices in America are extremely widely varied. I mentioned “waist high fescue and clover” in one of my previous posts about my trip to the Middle East. That kind of pasture can support completely different Ag practices than the Middle East or the dry range of Arizona. Cattle are still raised in Arizona: you just have to do it in a different fashion. All farmers face different conditions in different parts of their land. Even neighbors can experience quite different conditions relative e to pasture, water, and shelter. These just exemplify some of the variables every farmer faces.
