7 key principles to a healthy pasture
By Wayne Burleson
As I visit more and more farms and ranches and walk their pastures, I
find similar predicaments. That is, formal land monitoring by livestock
producers easily falls off the to-do list. When a Montana Sate
University student, Charley Orchard, did his master's thesis, he found
that less than one percent of Montana ranchers have a formal land
monitoring system in place. Also, the ones that did were not happy with
the method they used, and found the information collected was not very
helpful.
How sad! Seems that closets fill up with maps, old data and unused
photos. However, I do know that ranchers monitor one way or another.
Sometimes it's in their head (That's good.), sometimes it's looking out
the window of the pickup truck (That's fair.) and sometime it's when the
cows keep fence crawling because they've run out of feed and it's time
to move them (That's bad.). With today's economics and seemingly less
moisture to work with, I want to help change this land monitoring
dilemma.
Please consider the following seven ideas to help make pasture
monitoring much more meaningful. Clip out this article and place it in
the pickup truck. Then, the next time you find yourself wondering how
well your pasture management is doing, please re-read these seven
principles and then go take a closer look at the health of your
pastures.
P = Determine the
area's purpose.
Know the main purpose of the area to be grazed. Examples: profit from
livestock grazing, wildlife, shelter, aesthetics or special use. Why is
this important? If you have undetermined purpose, your management
decisions will be without direction. Don't skip this step!
A = Amount of time
spent grazing must be controlled.
Controlling the amount of time spent grazing in each unit (frequency
of grazing) in different seasons (the seasonality) is just as, or more,
important than the amount of forage removed (the intensity-utilization
levels) or what the animals are eating (their selectivity). Please
balance all of these key factors to have healthy pastures.
S = Supply adequate
rest to key plants for full recovery.
If you allow continuous grazing to occur on fresh regrowth on certain
high-producing plants, their roots will start to shrivel up and the
plants will begin to die. Please supply adequate rest to key plants
after each bite. Monitor their recovery period. How? Place a flag by a
previously grazed
plant and monitor the number of days for full recovery. Consider more
than one year's rest to bring back needed plants to full vigor. Also,
try "flash grazing" at low stock density, rotating from
pasture to pasture as fast as possible; use this grazing management on
very early spring pastures.
T = Test new ideas.
Experiment with small test sites before implementing major changes in
larger areas. Each pasture responds differently to different grazing
strategies. Construct enclosures (areas with no grazing) to evaluate the
differences in grazing treatments. This will let you compare grazed
areas to no-grazing. Example: Test "herd effect," the
trampling down of old vegetation to feed the soil, and then monitor the
results. If you find good results in smaller areas, implement changes in
larger ones.
U = Use litter to
feed the soils.
Available water is the biggest limiting factor for most plant growth.
We cannot control the amount of rain received, but we can control
grazing. Use the following rule of thumb: Keep the soils covered. Plan
pasture management to feed and shade the soil. Litter on the soil
surface will lower soil temperatures to conserve water. The old grazing
rule of "taking half and leaving half" works on the volume of
forage in the dryer, low-producing areas. However, this rule may waste
forage in high producing pastures. Plan land reclamation work during the
non-plant-growth season. Winter grazing is a great time to feed the
soils.
R = Rely on
diversity.
To increase diversity, use several different grazing methods,
systems, and strategies, strive to
increase different plant species and fine-tune your pasture management year after
year. Why use diversity? One example is that warm season grasses provide green forage later in the
season than do cool season grasses. Learn your areas' key indicator
plant species. This will help you to recognize when important changes are
occurring. Install photo points. Locate and mark areas on the ground
so that you can keep coming back each year to study the changes.
E = Evaluate results
-- monitor, monitor, monitor.
Use the feedback-loop method of monitoring - plan, control, monitor
and re-plan. Fine-tune each area by pastures walking often, looking for
any signs of stress occurring on any plant. Mark these problem areas.
Make needed changes in management to fix problems early. Consider
carrying over old forage for next year's early-spring-use pastures. Skip
grazing certain areas the second rotation. This will increase the energy
flow back into the soils. Add a pasture reserve for drought emergencies.
Determine the root causes of the problems and fix them - don't treat the
symptoms. The more pastures you have, the greater the flexibility will
be in leading you toward healthier pastures.
Please note: To accomplish many of these ideas, you must monitor
often. I know that these principles would mean change for most producers
(That's the hardest part.). I also know that if applied, these
principles can significantly change the health of your pastures (That's
exciting.). In today's tough agriculture times with the surge in
environmental awareness, it's now more important than ever to become an
astute grass farmer, rather than just doing things the same old way.
