SPRING – PLANTING SEASON – isn’t a good time to read David R. Montgomery’s
Growing a Revolution. Not when you live, as I do, in farming country. The plows are at work everywhere, from large green motorized behemoths to the horse-drawn antiques of the Amish. And, according to Montgomery, this is what not only has been destroying farmland around the world, it also probably was responsible for destroying past civilizations.
Montgomery sounded a death-knell over a decade ago in his book
Dirt, which took a pessimistic trip through a history of soil erosion and nutrient eradication, the long-range after-effects of what we thought was progressive agriculture. It stands alongside Bill McKibben’s
The End of Nature as a call for action falling largely on deaf ears, so Montgomery has revisited the topic in an encouraging, inspiring way. The needed changes can be made, he argues, and are being made – and in the unlikeliest places.
Growing a Revolution follows the author from country to country, climate to climate, to look at successful examples of no-till farming. As Montgomery is quick to observe, farmers generally aren’t given to change anything unless confronted with evidence of success, and that success needs to be seen in the harvests.
The key to Montgomery’s argument is conservation agriculture, the three components of which are “(1) minimum disturbance of the soil; (2) growing cover crops and retaining crop residue so that soil is always covered; and (3) use of diverse crop rotations. These principles can be applied anywhere, on organic or conventional farms, with or without genetically modified crops.”
