Mixed Fertilizers - Definition, Preparation and Compatibility.

The document discusses mixed fertilizers, defined as a combination of straight fertilizers supplying multiple nutrients, emphasizing both their advantages, such as efficiency and convenience, and disadvantages, including nutrient specificity and higher costs. It details incompatibility issues between various fertilizers, preparation processes, and physical and chemical changes that occur during manufacturing, such as hygroscopicity and reactions like double decomposition. The text provides guidance on the methods used to determine nutrient quantities in mixtures and stresses the importance of proper handling and storage to minimize nutrient loss.
