While some of the country is droughty, other folks have found that a cool spring and lot of precipitation means that the grass got away from them and is turning to seed heads. On Pasture Community members are asking each other “Should I mow?” “Should I trample?” “Should I just stockpile?” Here are some thoughts from Troy Bishopp, our own Grass Whisperer, when he ran into this problem in 2015.
I’ve got too much grass. Great gobs of gargantuan grass!
Wait! Did the Grass Whisperer just say that? Is there any such thing as too much soil-covering grass?!
Let me rephrase. I’ve got too much grass that won’t be harvested in a timely fashion and meet industry standards (8 to 10 inches), for proper grazing management. How did this happen? It’s simple. Three days over 85 degrees and several deluge rainfalls around May 10th propelled the cool season pasture into a growth frenzy. Such is the life of a Northeast grass farmer now turned prairie farmer.
If you’ll remember just a short time ago (and according to my grazing planning chart), we had a cool, dry spell around these parts of 14 days from April 25th to May 8th. Because of this, I was cautious in not taking the early pasture down too low with too many bovines. This knowledge was also suggested to my grazing clients at the conservation district. It was a good strategy against a wreck if it didn’t rain in the near future.
The reward for this conservative, sage advice? A flourishing sea of seed-heads waving like the prairies of yesteryear that fed millions of buffalo on the plains. Suspicious farming neighbors look at this phenomenon and ask when I’m gonna make hay or get the bush-hog out. Surely the gross gobs of over-growth would not be acceptable for a grazing animal of any prowess. It may even be construed as pasture mismanagement to some.
In the past few years, I’ve learned that this tall grass with its cohort understory of diverse forbs and legumes could actually be beneficial to animals instead of just being a jungle of rank forage. Some call it tall grass grazing, others call it mob grazing and still others identify it as holistic planned grazing. Personally I’m glad there is a selection of nice names and grazing techniques to work with, in covering up the reality that basically the paddocks got away from me.
I’ve indicated in the past that on my land I would like to emulate the prairie ecosystem as a standard so the thick, five foot high sward plays right into my hands. Wayne Fields wrote in Lost Horizon: “The prairie, in all its expressions, is a massive, subtle place, with a long history of contradiction and misunderstanding. But it is worth the effort at comprehension. It is, after all, at the center of our national identity”.
Since this condition of grass explosion happens every year on my farm against my futile attempt to corral it, I’m ever intrigued by what Mother Nature is trying to teach me. Author Dave Showalter said, “A passion builds inside anyone who spends time on the prairie”. To understand this dynamic of plant and animal interaction in a tall-grass grazing setting, I try to spend some time observing the subtleties of how it all works.
I notice how animals select from the vast array of plants as they nip off some seedheads, tear off a big burdock ear, bite off some dandelion flowers and bury their noses in the cool abyss of young clovers and bluegrass. Somehow they have figured out what they need in the diverse quantity for a healthy diet. The key to animal performance is giving them plenty of choice and fresh feed and not forcing them to clean up like a haybine went through unless you have dry stock that is more appropriate for this action.
The plant’s aura is showcased by the hue of a yellow pollen storm in the air and the shattering of seeds as the cows move through the biomass. This brushes off insects which call the many birds into a field for feeding their young. I’ve noticed the manure has more “body” which actually attracts more dung beetles than the high nitrogen squirting kind from much shorter swards. The trampling effect also creates habitat micro-chasms within a field for wildlife and for earthworms/microbes.
I just don’t see as many profound synergies with using mechanical mowing tools even though we keep them in our toolbox. As I get older, my appreciation for seeing the benefits of planned tall-grass prairies is outweighing the distinct need to mow for hay or keep the place pristine and tidy for the passerby that judges my management by how manicured the grass is.
This notion of grazing taller forage with maximum selection is starting to catch on among my peers. I have several friends who are garnering more milk and components from these older non-native swards which if you looked at them, it would leave you scratching your head. The plant and animal biology interactions are seemingly trumping the science. It’s pretty complex figuring out what a bite of milkweed, grass and clover actually does for an animal. A recent pasture walk showed the highest brix (sugar) readings came from the “weeds” that the animals were consuming.
Alas this gargantuan, prairie-like growth spurt is usually over by Independence Day and the paddocks rarely see the seed-heads again after whatever harvesting technique diminishes the mass into something more manageable. So take heart that you will eventually gain control of your grass again and start to recognize the fence-lines without cutting a path first.
