Tellus<\/em> did a complete mineral analysis of seven of our pastures using Brookfield Labs in Ohio.\u00a0 We tested three of our mob grazing pastures against others that were used in the usual way.<\/p>\n

Mob grazing puts more pounds of beef on a very limited area and moves the animals off quickly to the next small area.\u00a0 The belief is that this “pressure” will result in more fertile soil, more organic matter because of the trampling effect, better use of all the plants, and healthier cows because they’re eating only the tops of the grass and then move on.<\/p>\n

Our “eye” told us we had probably had a more efficient use of the grass but we also saw some signs we didn’t like:\u00a0 more weeds, bare patches of soil.\u00a0 Tim in the picture is pointing out a patch of dead foxweed and beneath it the soil is bare.\u00a0 Not good.\u00a0 That’s a place that will take a while to repair and it also is a place where ground temperature will be higher and water-holding capacity will be less.<\/p>\n

Some of that is our fault.\u00a0 We didn’t move the cows off this area quickly enough and that permitted the foxweed to take hold.\u00a0 But that’s not the entire story.\u00a0 And there are other, more troubling weeds, like rosa-multiflora, taking hold that will have to be battled.<\/p>\n

As for the soil itself, the reports are indeterminate.\u00a0 Our fertility was generally good to begin with and that continues to be the case.\u00a0 We need to add a little Boron in a few pastures, but that was unrelated to mob grazing.\u00a0 PH was excellent across the board…..very close to 6.5 everywhere though maybe slightly better in the mobbed areas.<\/p>\n

The clearest indication that mob grazing made an improvement was organic matter, definitely better in our mob pastures versus the nearby standard pastures.<\/p>\n

So what will we do?\u00a0 First, spray a natural, liquid Boron on those areas that need it.\u00a0 We will also lime a few pastures which were closer to 6 than 6.5 to bring up their pH.\u00a0 That’s a “tweaking” exercise; we don’t want to get the pH too high.<\/p>\n

The most difficult job will be getting rid of the weeds.\u00a0 We’ll use mowing and machetes.\u00a0 Not herbicides.\u00a0 And wherever possible, we’ll dig out the roots on the Rosa-multiflora.\u00a0 But that’s going to be an on-going battle.<\/p>\n

Are we satisfied that mob grazing is the answer for us?\u00a0 A tough question and the honest answer is: not yet.\u00a0 We said we would try this for two years and we’ve already begun Year Two.\u00a0 You can see the cows in the background\u00a0of the picture\u00a0in the first paddock.\u00a0 We have decided to make some modifications:\u00a0 giving them bigger paddocks, moving them faster, and (totally breaking the rule) knocking down weeds before they mature.\u00a0 That means bush-hogging, which we thought we were through with.<\/p>\n

Most painful: we have decided our stocking rate is just a little too high for the amount of land we have….particularly with a group of English heifers due to arrive in about a month.\u00a0 So five of our mamas are going to have to go.\u00a0 A tough decision.<\/p>\n
