Apearently It comes from the Native Americans who would grow Corn, Beans and Squash together. The corn stalks would provide a trellis for the beans to grow on, and the squash would grow on the ground and provide cover to control the weeds. Sounds intresting. Anyone else heard of it? Anyone tried it? I tried it a couple of years ago It sounds like a good idea but it didn't do any better than conventional techniques. ??? Well, did the plans yeild the same compared to if they were planted separatly? Wouldn't the yeild of (say) 100sf of soil be higher compared to planting separatly? For instance: 100sf of corn, 100sf of squash, 100sf of peas == 300sf of garden. VS 100sf of everything growing together? No. The Fatal Harvest Reader by Andrew Kimbrell (Editor) http://www.amazon.com/Fatal-Harvest-.../dp/155963944X /ref=sr_1_1?ie=UTF8&s=books&qid=1220837838&sr=1-1 (Available at a library near you, until they are closed, because of Wall Street's bailout.) pg 19 Agribusiness and economists alike tend to use "yield" measurements when calculating the productivity of farms. Yield can be defined as the production per unit of a single crop. For example, a corn farm will be judged by how many metric tons of corn are produced per acre. More often than not, the highest yield of a single crop like corn can be best achieved by planting it alone on an industrial scale in the fields of corporate farms. These large "monocultures" have become endemic to modern agriculture for the simple reason that they are the easiest to manage with heavy machinery and intensive chemical use. It is the single-crop yields of these farms that are used as the basis for the "bigger is better" myth, and it is true that the highest yield of a single crop is often achieved through industrial monocultures. Smaller farms rarely can compete with this "monoculture" single-crop yield. They tend to plant crop mixtures, a method known as "intercropping.' Additionally, where single-crop monocultures have empty "weed" spaces, small farms use these spaces for crop planting. They are also more likely to rotate or combine crops and livestock, with the resulting manure performing the important function of replenishing soil fertility. These small-scale integrated farms produce far more per unit area than large farms. Though the yield per unit area of one crop ‹ corn, for example‹may be lower, the total output per unit area for small farms, often composed of more than a dozen crops and numerous animal products, is virtually always higher than that of larger farms. Clearly, if we are to compare accurately the productivity of small and large farms, we should use total agricultural output, balanced against total farm inputs and "externalities,''' rather than single-crop yield as our measurement principle. Total output is defined as the sum of everything a small farmer produces ‹ various grains, fruits, vegetables, fodder, and animal products ‹ and is the real benchmark of 'efficiency in farming. Moreover, productivity measurements should also take into account total input costs, including large-machinery and chemical use, which often are left out of the equation in the yield efficiency claims. Perhaps most important, however, is the inclusion of the cost of externalities such as environmental and human health impacts for which industrial scale monocultured farms allow society to pay. Continuing to measure farm efficiency through single-crop "yield" in agricultural economics represents an unacceptable bias against diversification and reflects the bizarre conviction that producing one food crop on a large scale is more important than producing many crops (and higher productivity) on a small scale. -- - Billy E pluribus unum http://www.rollingstone.com/politics/news/the-great-american-bubble-machine-20100405 http://www.npr.org/templates/story/story.php?storyId=96993722 |
