System
Dryland farming is uniquely dependent on natural rainfall, which can leave the ground vulnerable to dust storms, particularly if poor farming techniques are used or if the storms strike at a particularly vulnerable time. The fact that a fallow period must be included in the crop rotation means that fields cannot always be protected by a cover crop, which might otherwise offer protection against erosion.

Famous quotes containing the word system:
“An avant-garde man is like an enemy inside a city he is bent on destroying, against which he rebels; for like any system of government, an established form of expression is also a form of oppression. The avant-garde man is the opponent of an existing system.”
—Eugène Ionesco (b. 1912)
“In a universe that is all gradations of matter, from gross to fine to finer, so that we end up with everything we are composed of in a lattice, a grid, a mesh, a mist, where particles or movements so small we cannot observe them are held in a strict and accurate web, that is nevertheless nonexistent to the eyes we use for ordinary living—in this system of fine and finer, where then is the substance of a thought?”
—Doris Lessing (b. 1919)
“The United States is unusual among the industrial democracies in the rigidity of the system of ideological control—”indoctrination” we might say—exercised through the mass media.”
—Noam Chomsky (b. 1928)
