The Chemistry of Fertilisers and Manure – Including Information on the Chemical Constituents and Types of Fertilisers and Manures 

This early work on the fertilisers and manure concentrates on the chemistry behind them, examining their different types and how they are made. Written in simple, clear language and profusely illustrated, “The Chemistry of Fertilisers and Manure” will appeal to those with an interest in the history and development of modern agricultural techniques. Contents include: “Soil Science”, “Fertilisers And Manures”, “Nitrogenous Fertilisers”, “Phosphatic Fertilisers”, “Potassic Fertilisers”, “Agricultural Salt”, “Determination of Sodium Chloride”, “Lime, Hydrated Lime And Carbonate Of Lime”, “Mixed Or General Manures”, “Potassium Nitrate”, etc. Many vintage books such as this are increasingly scarce and expensive. It is with this in mind that we are republishing this volume now in an affordable, modern, high-quality edition complete with a specially-commissioned new introduction on soil science.
