We have seen the countless pastures
and croplands driving along the highway displaying a monoculture of animals or
crops. This has been the norm for
centuries and we have come to believe this is the best practice and most
profitable use of the land. The practice
of monoculture can almost not be seen outside the practices of the rancher or
farmer. If you walk into any supermarket
or shopping mall, you will notice that these stores carry a wide array of
products. Retailers have recognized that
trends in the market change constantly and to continue making a profit they
must diversify their goods.
Ranchers, farmers, and even
woodland owners can make use of diversification in goods to maximize profits
and sustain land-use for the future.
Agroforestry is a management tool that integrates trees or other woody
vegetation with crops and/or livestock to create a profitable, productive, and
sustainable land-use. There are 5 key
practices in agroforestry and all of them incorporate trees that will provide an
additional profit either in the near future, planting nut or fruit trees, or as
a long term investment, by planting trees for fiber or veneer.
Forest farming is a useful
management tool for farmers in the business of specialty crops. Trees that will turn a profit for the farmer,
either in food or fiber, are planted amongst other specialty crops to provide
the correct protection from sun and other weather conditions. Crops that require shade, such as shitake
mushrooms and ginseng, are ideal for this practice. Forest farming also provides an ideal habitat
for large and small game that can be used as a profitable good, either by
leasing the land to hunters or personal consumption.
Alley cropping utilizes rows of
trees to protect crops from weather conditions and diversify income. Agricultural or horticultural crops are
planted in alleys between the rows of trees.
The trees planted could either be trees that produce food (nut or fruit)
and/or timber.
Silvopasture combines trees, forage
and livestock in a single consolidated practice. Grasses and legumes that will provide feed
for livestock are planted between rows of trees. The trees will provide a source of income in
the near future by the way of planting nut or fruit trees and a long-term
investment when trees are planted that will be of value in timber or
veneer. The livestock will benefit from
the shade the trees provide in the summer and as a windbreak in the winter.
Riparian buffer strips are living
filtration systems comprised of native vegetation that offers many
benefits. Buffer strips between riparian
zones and croplands are planted with native perennial trees, shrubs, and
grasses. These zones act as a filtration
system of nutrients from surface run-off and serve as an effective way to
control erosion. Waterfowl favor the
habitat created by riparian buffer strips, where hunters can find an abundance
of birds to harvest.
Windbreaks serve not only as
protection from soil erosion, but also protect crops that are susceptible to
windthrow and livestock from harsh weather conditions. These are planned and actively managed along
with the livestock and/or crops.
Coniferous trees are usually planted for windbreaks, because they hold
onto their needles year round and reach tall heights. Windbreaks attract edge species, many of
which are game animals and can present excellent hunting for the rancher or
farmer.
Incorporating trees with your
animals and/or crops has been researched by scientists and practiced by many
ranchers and farmers, and proven to be productive and profitable. This integrated system reduces costs and
increases productivity through the practices of agroforestry, a practice that
utilizes sustainable land-use. Production
of annual litterfall from the overstory and the retention of organic matter and
carbon into upper soil profiles by the trees will improve soils and reduce the
cost to treat soils. The perennial root
systems of the trees result in minimal soil erosion on the land, which will
save the rancher or farmer in repair bills or lost crops due to the
erosion. Water quality will improve with
reduced run-off of nutrients and soil, which otherwise would end up in nearby
water sources, not being fully utilized by the land.
Agroforestry is a management
practice that delivers productivity and profits through diversifying the
livestock and/or crops being harvested and reducing costs in soil and water
treatment.

I want to start by saying I belive this is a great idea and that I really wish more farmers could impliment these stratagies. The problem I see with it is that our government and our economy is pushing for more and more ethanol production. Now ethanol can be produced from a variety of things but mostly as of right now it's being produced with corn. This huge demand for corn has skyrocketed the prices and has forced many cash crop farmers to plant corn and only corn, year after year. Just in the county where I'm from in the last 3 years I have seen more forests cut, dozed and destumped than I had my entire life prior. The land wasn't developed or used as hay field it was planted to corn. There is just no way a farmer can get the return from woodland that he can on corn especially as cheap as fertilizers are nowadays. I think there would have to be government subsidies or some reform in our ethanol production before we could see a real change in agro-forestry.
