There is now clear consensus among most rural producers, scientists, bureaucrats and politicians that many of Australia's farming systems are unsustainable, using present methods. While broadacre agriculture has been considered by some to be technically sustainable, economic pressure placed on farmers due to declining terms of trade is indirectly responsible for the instability of many farming systems. The current awareness stems from irrefutable evidence that our crop and animal production methods have resulted in both dramatcic and insidious forms of land degradation. However, the sustainability of our farming systems has been questioned for some time, and at least three symposia dating from 1983 have dealt largely or wholly with this issue. Sustainable agriculture is now in vogue, so much so that one rural magazine now carries the slogan "Striving for Sustainable Agriculture" as its banner. And Australia now has a National Association for Sustainable Agriculture (NASAA). It should then be easy to define a sustainable farming system, particularly if the definition is restricted to cropping.

In Gilford, Montana, where the average annual rainfall is 11.7", most farmers use summer fallow. But one farmer, Levi Hansen, does it in a non-traditional way. He seeds yellow sweetclover right along with the spring wheat. The wheat comes up before the clover. When the wheat is cut in the fall, the clover overwinters and comes on strong in spring. By May 15th, Hanson plows the clover in and cultivates during the summer as a normal fallow. He credits the sweetclover with helping keep yields up by increasing organic matter, tilth and water-holding capacity of his soil. He also estimates that the summer fallow produces an additional 60 lbs of nitrogen as crop residues break down.
