Fertiliser refers to any material which can be introduced to soil to provide nutrients essential to the growth of plants, either natural and industrially produced. This vintage book contains a complete handbook on the subject, offering the reader information on where they come from, how they are produced, made, used, and much more. Contents include: "Difference Between Barn Manure and Commercial Manure", "What is Barnyard Manure?", "Humus", "Are Fertilizers but Stimulants", "Potash", "Wood Ashes", "Coal Ashes", "Cotton-Seed Hulls", "The Uses of Potash in Agriculture", "What is Nitrogen?", etc. Many vintage books such as this are increasingly scarce and expensive. We are republishing this volume now in an affordable, modern, high-quality edition complete with specially-commissioned new introduction on agriculture and agronomy.
