So there you go the ins and outs, ups and downs,yeas and nays of it.some good and some bad some deadly some a blessing. BUT one thing you can be sure of is if it's growing on your place you have some pretty good ground. If it were covered in cockleburs and sand burns not so much. So you have a choice leave it and use it,or try to make your place into what you believe is the ideal. Just remember to get rid of it mechanically you'll have to deep plow it which is going to turn all that rich soil under and bring to the top all that less nutrient rich soil. Anything less is simply cultivating it. Or you can spray it with a herbicide that will kill everything else also and start over from nothing. IF your afraid of it you can do like most of us old guys who didn't have the internet did. Simply turn your cows out on it for a few minutes them run them back out.next day let them stay a little longer. Keep on till their guts get used to processing it. That's the proper way to change pastures or feed anytime. How many times have you seen guys throw a bunch of calves out on wheat pasture and the next day they were all scoured. Same difference just takes time for cattle to adjust.
