Low Impact Pasture Renovation

 1311650-1354960-thumbnail.jpg

Field of Broomsedge 

The picture above is one of the first pictures we took of the farm, before we even owned it. This was taken 14 months ago.  Half of our pasture was covered with a wispy, broom like grass that was so tall, we couldn't see the terrain features. It scared Liz to death when I drove the truck right through this field of what we later learned was primarily broomsedge. There was a lot of dog fennel in there as well. Neither of these is "desirable", we later learned, for grazing.  So, they would have to be "weeded out" so to speak.  But since we were against using chemicals on the land, how would we do this?  Thus began our adventure to heal and restore1311650-956641-thumbnail.jpg

our pastures with as little impact as possible.

We started with a soil test which confirmed that our land, like most in the south, was low in pH and organic matter. In fact, broomsedge is often a fairly accurate barometer of the acidity and organic condition of the soil.  So, right away (to buy me some time), I cautioned Liz that it would take three years in my opinion to restore the pastures to great grazing condition. The strategy I deployed included these steps:

  1. Begin mowing (bush hogging) the pasture frequently to knock down the weeds, thus preventing them from shading the grasses and encouraging the grasses to grow.
  2. Lime the pasture at least twice, once last fall (which I did) and again this spring (which I will do) to increase the pH and create a less favorable environment for broomsedge, dog fennel, etc.
  3. Only plant new forage very selectively and only in the first year of operation. 
  4. Focus on improved management strategies for three years and see what impact the effects are of management intensive grazing.  In other words, help the animals do the work.

Last year I bush hogged a lot.  Late last fall, I broadcast spread ryegrass, which is now coming up and will take root and shade out some of the weeds. Half of our pasture is a beautiful old stand of tall fescue which, regrettably, is not the endophyte-free variety and therefore, poses a risk of toxicosis.  However, the endophyte is located near the seedhead so I figured that I could mitigate this risk by managing rotations carefully to ensure it never approached that level of maturity.  So far it's working like a charm and the cows love it.

Additionally, my plan was and is to seed in Durana Clover, a persistent, productive and long-lived white clover that would fix nitrogen in the soil, provide a wonderfully nutritious legume option for the grazers and reduce the density of the fescue in that field.  However, to ensure the best chance of success in establishing the clover, I needed to increase the soil pH; hence the need for a second application of lime this spring.   As Durana Clover is a cool-season forage, I will plant it with a no-till seed drill this fall.

Spreading pasture seed
Other than the clover, I have no plans to mechanically plant anything else.  However, that doesn't mean I'm not doing my part to add variety and new sources of forage to the pasture. As part of introducing new forages only in the first season, I opted to hand seed selected forages along with daily rotation of the cows.   My plan was to create a pasture mix of nutritious and palatable forages that were missing in our pasture, and to seed them by hand daily just before moving the cows to their new paddock. The picture to the left shows me doing just that this last weekend.  Those cows are mesmerized by my every move, waiting patiently for their new salad to grow.  Either that or their anxious for their daily move.

Joel Salatin likes to use the phrase "salad bar" when describing ideal forage for his animals, and I think that's a good description of what we're going for.  A lot of farmers in Georgia, and elsewhere, will plant one crop, such as Coastal Bermuda.  This may make fine horse hay and sells for a "pretty penny", but would you want to eat just that every day?  Liz and I often sit right in the middle of the cows and watch them graze. They can be so selective in determining what they want., so we want to give them a varied diet.  The mix I'm spreading in the picture consists of three cool-season forages; Crimson Clover, Puna Chicory and Birdsfoot Trefoil. 

The Chicory is leafy, highly palatable and has a deep taproot, making it a good choice for drought climates.   It's actually an herb and provides both spring and summer grazing.1311650-1355039-thumbnail.jpg

The Trefoil is also a highly palatable forage and quite beautiful to look at with its yellow flowers. Perhaps you've seen it...click here to see a picture.

And the Crimson clover will provide similar benefits to those mentioned previously for the Durana Clover.

Why did I plant them this way, and will they "take" without being "drilled" into the soil?  Well, they probably won't take without being drilled, but I decided to let the cows do the drilling for me. Their toes are magnificently designed to twist and turn, pushing any seeds spread before them right into the soil as they graze away.  As if that's not enough, they're kind enough to fertilize the planting for me, all in the same day before repeating the cycle again the next day in the ensuing paddock.  The picture to the left shows the cows hoof print after a grazing 1311650-1355048-thumbnail.jpg

day, with the seeds being pushed firmly into the soil.  Sure, this is a fair amount of work (for me, not the cow) and will take some time, but it's a good way to introduce new forages into our pasture since we're out there moving the cows anyway. And it give us a few extra minutes with them which is always a pleasure.  But, man are they impatient. Moo, moo, moo is all I hear which translates into "hurry up and finish and moooove us!".

In the end, I still think three years is the right answer.  Pasture condition, in my opinion, reflects the management quality of that pasture more than anything else.  We all like to say it's the drought, weeds, etc., but in the end we can't control drought. We can control how we manage the land and the grazing, and I believe that proper management will return this land to beautiful, palatable and highly nutritious grazing land.  Time will tell.

I have been following your blog for some time, and am excited to see this all coming together for you. We intend on taking a portion of my father's cow-calf ranch in North Western Arkansas and turn it into a diversified farm to provide real food to our local community.

My question is concerning the rotation. In Joel's system, he follows up herbivores with poultry. Will your rotation system follow a similar path, and is there any concern about some of your forage seed becoming chicken feed? How big are your paddocks, and how long do the cattle stay in them before they are moved?

Thanks!

Hi Brian,

Yes, we have built one eggmobile already out of a cotton trailer, and will put layers on pasture next month. Since we move the hens 4 days behind the cows, and given how well the cows push the seed into the ground, I'm not concerned about that. The hens will be interested in A) insects, B) forage and C) the supplemental grain.

Right now, we're making paddocks about 1/4 an acre and move the cows every day at 4:00 p.m. or so.

Best of luck to you, and thanks for writing!

Tim,

Thats awesome. Sounds like we pretty much have the same soil. Just got 148 tons of lime put out and am in the process of putting mushroom compost throughout the pasture. Then comes the seeding. Isn't it amazing to look at the difference just a year makes on land that had been let go but is allowed to heal. Yall have a beautiful place.

I'm glad to stop back in catch up on your farm goings-on today. We don't have cows, but we do eat beef, and I'm quite impressed with your pasture management techniques and the focus on the health and enjoyments of your cows.

Well done.

Thanks Jason!

Hard-Fun-Rewarding work. Only problem is it takes some patience...not exactly my strength :)
