Studies of sediment core samples on the bottom of the Gulf showed that nitrogen levels began to rise in the 1950s, just as commercial nitrogen fertilizer came on the market. As the use of both fertilizer and agricultural tile drainage rose, so did the concentration of nitrogen in the MississippiThe book provides a chapter telling the history of the dust bowl years in the 1930s. My parents lived through this era and the farm I grew up on during the 1950s was blessed with a grove and shelterbelts planted in the 30s in an effort to control erosion.
... planted nearly forty million saplings on the Great Plains to create windbreaks that Roosevelt called prairie shelterbelts. Nearly one million acres were taken out of crop production and replanted with drought-hardy grasses.The book provides a thorough description of the variety and density of life found in the typical soil of native prairie.
A plot of healthy soil the size of a kitchen stovetop can contain as many as 1,000 earthworms, 60,000 mites, 100,000 arthropods, millions of the minuscule worms called nematodes, fully one pound of bacteria, and more than 100 miles of fungal filaments. David Montgomery notes that just a tablespoon of soil contains more living things than the human population on Earth. And when all those living things die-plant roots, worms, insects, fungal threads-they add more carbon to the soil. Repeat that process thousands of times over hundreds of years, and you understand why prairies have some of the richest soil on the planet. The famed black soil of the Midwest is black for a reason—it's loaded with carbon.There's also a discussion of the use of pesticides, the role of pollinators, and alternative farming procedures that have been developed to protect soils from erosion and depletion.
Worse, breaking these grasslands is not a one-time loss. It not only releases their stores of carbon, it removes them as a carbon sink that could capture future greenhouse gas emissions. Grass preserves 60 to 70 percent of its carbon below ground, permanently. And once plowed, prairies require a century or more to recover the original plant diversity and productivity that allow them to sequester so much carbon ... .There's a chapter in the book describing the development of Glacial Ridge National Wildlife Refuge in the Red River Valley located between northwest Minnesota and eastern North Dakota. There's also a discussion of improved farming and ranching methods, and a chapter describing the reintroduction of bison to parts of the short grass prairies.
