Rototilling
I prefer no-till "Lasagna" gardening, or "Sheet Mulching" as others call
it. To my way of thinking it is the best way to garden, and it requires less exertion. --- Gaia's Garden, Second Edition: A Guide To Home-Scale Permaculture (Paperback) by Toby Hemenway http://www.amazon.com/Gaias-Garden-S...culture/dp/160 3580298/ref=sr_1_1?ie=UTF8&s=books&qid=1271266976&sr=1-1 p. 81 - 82 To Till or Not to Till We've seen that organic matter keeps soil light and fluffy and easy for roots to penetrate. What then about the mechanical methods used for breaking up soil? The invention of the plow ranks as one of the great steps forward for humanity. Farmers know that plowing releases locked-up soil fertility. Plowing also keeps down weeds and thoroughly mingles surface litter with the soil. We do all this, too, when we drag our power-tiller out of the garage and push the snorting beast through the garden beds in a cloud of blue smoke. What's really happening during tilling? By churning the soil, we're flushing it with fresh air. All that oxygen invigorates the soil life, which zooms into action, breaking down organic matter and plucking minerals from humus and rock particles. Tilling also breaks up the soil, greatly increasing its surface area by creating many small clumps out of big ones. Soil microbes then colonize these fresh surfaces, extracting more nutrients and exploding in population. p.82 This is great for the first season. The blast of nutrients fuels stunning plant growth, and the harvest is bountiful. But the life in tilled soil releases far more nutrients than the plants can use. Unused fertility leaches away in rains. The next year's tilling burns up more organic matter, again releasing a surfeit of fertility that is washed away. After a few seasons, the soil is depleted. The humus is gone, the mineral ores are played out, and the artificially stimulated soil life is impoverished. Now the gardener must renew the soil with bales of organic matter, fertilizer, and plenty of work. Thus, tilling releases far more nutrients than plants can use. Also, the constant mechanical battering destroys the soil structure, especially when perpetrated on too-wet soil (and we're all impatient to get those seeds in, so this happens often). Frequent tilling smashes loamy soil crumbs to powder and compacts clayey clods into hardpan. And one tilling session consumes far more calories of energy than are in a year's worth of garden grown food. That's not a sustainable arrangement. Better to let humus fluff your soil naturally and to use mulches to smother weeds and renew nutrients. Instead of unleashing fertility at a breakneck, mechanical pace, we can allow plant roots to do the job. Questing roots will split nuggets of earth in their own time, opening the soil to microbial colonization, loosening- nutrients at just the right rate. Once again, nature makes a better partner than a slave. ----- McGowan's Drinking Guide (Translated from the original German. It's complicated, OK?)

This world in arms is not spending money alone. It is spending the sweat of its laborers, the genius of its scientists, the hopes of its children. This is not a way of life at all in any true sense.
