Home Base -- Creating a Sacrifice Area: Can You Afford Not To?
Sacrifice Area sounds like a place where grisly happenings occur. In fact, its
purpose is to prevent the gruesome things that can happen to exercise lots and
pastures that are not planned and managed well. Perhaps better known in the
horse world as Dry Lot, Turn Out Lot, Exercise Lot, Corral, or Paddock, the
term Sacrifice Lot was coined by grazing management enthusiasts. The concept
is that a selected area is sacrificed from the grazing system and is used to
confine animals in order to protect pastures from over-use at critical times
(i.e., winter months, wet soils, and times of slow pasture plant re-growth --
rest periods). They can be the key to good pasture management, especially
where horses are concerned. They are also excellent in terms of horse
management such as preventing over-consumption of lush pasture forage, and in
juggling the turnout of compatible groups of equines when pasture area is
limited. In cases where there is no pasture at all, horses may spend 100% of
their outdoor time in this area. Few facilities in Connecticut can afford to
be without a properly designed sacrifice lot. Benefits of a Well-Planned
Sacrifice Area
- Hoof-friendly surface for better horse health
- Reduction of mud and ice
- Ease of manure removal/management
- Improved aesthetics
- Reduction of manure- or soil-laden runoff to water bodies
- Reduction of fly-breeding habitat
- Improved pastures utilizing the sacrifice area as a management tool
What Makes a Well-Planned Sacrifice Area?
- Minimal Size - Reducing the amount of bare soil on your equine facility
will help you to achieve all of the listed goals of BMP’s, as well as reduce
the distance you must wander with pitch fork and wheel barrow in your daily
quest to remove manure. Consider the space needs for your particular herd,
groups, or individual, and the amount of pasture and riding exercise that
supplements their turnout time. Create a Sacrifice Area that is no bigger
than what you require. Keep in mind that there are limits to a particular
property’s ability to support animals. Sadly, you may have to face the fact
that you just cannot house the number of horses you’d like to at your
current location without causing detrimental impacts to the environment. In
some cases this challenge may be answered by drastically reducing turnout
time and space, combined with meticulous manure management and disposal.
- Create a Good Surface - You may need to remove as much of the
fine-textured "topsoil" as is practical, and replace with 8-12 inches of
well-draining gravel. Compacting the gravel well with machinery will help to
lock the larger particles (stones) in place. Gravel should be well-graded,
meaning it should have an assortment of particle sizes from sand and some
fines up to stones of one inch in diameter. Larger stone size may be
detrimental to hooves, and even a base containing 1" stone may need to be
covered to prevent bruising. You may wish to top with stone dust or sand for
a hoof-friendly footing. A good surface is a key part of any mud-reduction
plan. Some areas may require subsurface drainage (curtain or tile drains)
where seasonal perched or high water tables exist. Spots that are
particularly troublesome due to heavy traffic and/or wetness (NOT wetlands!)
may benefit from the use of a geotextile covered with 8+ inches of gravel
base and your choice of surface material.
- Location - The most convenient areas are generally near the barn.
However, it is most important that the sacrifice area be located away from
wells, wetlands, and water bodies. Strive for a minimum of 200 feet
separating distance when possible. Utilize other BMP’s such as Vegetated
Filter Areas and Water Diversions (including roof gutters) to help overcome
shortcomings. Slopes of 2-4 % will reduce ponding of water, and will have
less erosion than steeper slopes. A slope of 2 % means that over a distance
of 100 feet, the elevation will change by 2 feet. Grade the area to drain
away from barns.
- Daily Manure Removal - Regular removal of manure from the lot surface
will result in less polluted runoff leaving the site, and will help to
prevent the incidence of mud. Left in place, organic matter in the form of
manure or wasted feed and forage will get churned into the surface,
increasing the water holding capacity of your lot, which means more mud!
