Guano: A Treatise of Practical Information for Farmers

"Guano: A Treatise of Practical Information for Farmers" by Solon Robinson is a guide for 19th-century American farmers about using Peruvian guano, a powerful fertilizer. It aims to teach farmers how to best use guano on different crops and soils, arguing it's better than old-fashioned manure because it boosts crop growth more efficiently and cheaply. The book talks about where guano comes from, how to get it, and what it's made of. The book starts by talking about the increasing availability and effectiveness of guano as a fertilizer for American farmers. Robinson points out that many farmers don't know how to use guano properly. He includes stories and results from farmer experiments showing how guano significantly improved their harvests, because he wants them to see guano as a game-changer for their farms.
