Farming as nature intended. A “dynamic duo” from south of the border, brings a message of hope and radical change to producers on the Canadian prairies.
by Larry Powell A conventional farm in Manitoba. A PinP photo. "You're tilling too much!" That was Ray Archuleta's blunt message to about 50 people at a meeting this week in the small, farming community of Shoal Lake, Manitoba. The brilliant, affable Archuleta operates a small ranch in Missouri. His partner. Gabe Brown, whose "down home" personality has apparently earned him the monicker, "Farmer Brown," runs a big, mixed operation in North Dakota. Both men are on the same mission - convince as many farmers as they can to move away from conventional production. That's how countless producers in Canada, the U.S. and developed countries around the world, have, for decades, practised this predominant style of agriculture. They rely on heavy and expensive "inputs" of fertilizers, pesticides, machinery and "mono-crops," all designed to produce the highest yields possible. Ray Archuleta conducts a "slake t

New York City isn't known for having the cleanest air, but researchers traced recent air pollution spikes there to two surprising sources — fires hundreds of miles away in Canada and the southeastern U.S. Story here.
One of the biggest challenges facing the aquaculture industry everywhere, is Lepeophtheirus salmonis , the sea-louse (below). It's a parasite which attacks both farmed and wild salmon, causing lesions and infections which stunt their growth. But the costs of de-lousing are high. And so are the losses suffered by the industry in the marketplace. Many lice can actually kill many fish. Sea lice, Lepeophtheirus salmonis, on farmed Atlantic salmon, New Brunswick, CA. Photo by 7Barrym0re To fight back, the fish-farmers dump pesticides into the waters (below). But, because they’re released directly into the environment, they not only kill the lice, but place beneficial, “non-target” organisms at risk, too. And several of these live in the open ocean, beyond the confines of the farms. The latest (but not the only) cautionary tale about the wisdom of this practise, has just emerged from Norway. A team of researchers there exposed (in the lab), an important food source for the
