About the book

Going away from the traditional style of explaining the origin and composition of fertilizers and manures, the author describes lucidly their mode of action and their relation to particular crops and soils. Enriched with tables of scientific data, the text covers the need, sources, functions, uses and also a comparative analysis various fertilizers and manures—Nitrogenous, Phosphatic and Potassic. Manure is a natural fertilizer. To make manure, decomposition of plants and animal waste is done by farmers. The product of this decomposition is a material rich in organic matter which we call manure. Manure does not have a high content of nutrients. Instead, it gives fertility to the soil by adding humus. This improves the soils physical properties, with better retention of moisture and more aeration. Fertilizers are natural or synthetic materials that we add to the soil to provide the plants with the nutrients they need to grow to their fullest and at a faster rate than attained via a natural process. Chemical-based fertilizers also act as an insecticide, protecting plants from pests and insects. On the whole, it is a unique book on the applied aspect of fertilizers and manures, telling how to adjust them to particular soil and particular style of farming.
