Fertilizers And Their Use

Rationale for the need of fertilizers (increase of production and increase of farm income); Nutrients - their role for the plant and their sources; Soils; Fertilizer recommendations for selected crops according to their needs; The importance of balanced fertilization; Fertilizers, their appearance, quality, labeling; Calculation of fertilizer rates; How to apply fertilizers; Hot to determine fertilizer needs; Other factors limiting crop yields; Fertilizer extension work.

This vintage book contains extensive information on fertilisers, exploring their various ingredients, how they are used, what they do, and much more. A veritable encyclopaedia on the subject, “Handbook of Fertilizers” contains much information that will be of use to the modern farmer or gardener, and it would make for a fine addition to collections of related literature. Contents include: “Requirements For Plant Growth”, “Nitrogeneous Fertilizer Materials”, “Phosphatic Fertilizer Materials”, “Potash Fertilizer Materials”, “Effects Of Fertilizers On”, “Crops And Soils”, “Factory-Mixed Fertilizers”, “Home-Mixing Of Fertilizers”, “Purchase And Use Of Fertilizers”, 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.

The present edition of the book contains completely revised information on new technical developments and knowledge. The handbook explanis the need for mineral fertilizers, their role in plants and soil characteristics which are relevant to fertilization. A new section provides general recommendations for selected crops. The chapter on How to determine fertilizer needs includes information on deficiency symptoms and on soil and plant tissue testing. A chapter is devoted to explaining and giving advice on laying out fertilizer demonstrations and on extension techniques in general. The book contains rationale for the need of fertilizers (Increase of Production and increase of farm income) by increase in crop yields and improve fertilizer efficiency. Nutrients their role for the plants and their resources, Soils Fertilizers. The present book would prove useful for post graduate students of Agriculture. Soil Science and Agronomy. Also useful for farmers.

This book describes many important principles of fertilizer management and the environmental pollution problems due to the indiscriminate soil fertilization rate. The long-term impacts of organic or mineral fertilizer use have implications on soil fertility, crop yields, water quality, climatic change, greenhouse gas emissions, etc. Twelve chapters provide the state of the art of some important topics on subsistence agriculture, modern agronomy, and technological improvements which have sharply increased yields from cultivation, with a special emphasis on the sustainable management and environmental impact of commercial and nontraditional fertilizers. Without a doubt, this book is a valuable contribution to the agricultural sciences and it would not have been possible without the invaluable contributions, immeasurable acknowledgements, and recognized expertise from the authors.

Despite The Considerable Progress Made In Enhancing The Capacity Of Soils To Produce Crops Through The Use Of Manures And Fertilizers, There Are Yet A Large Number Of Ignorant Peasants In Many Asian Countries, Including India, Who Have Been Growing Crops Without Applying Adequate Amounts Of Manures And Fertilizers To Their Crop Fields And Consequently Obtaining Considerably Less Yields. It Needs To Be Realized By One And All That Soil, Particularly In The Developing Countries, Has To Be Fertile Enough If Their Ever-Increasing Huge Population Is To Be Adequately Fed And Clothed. Accordingly, Knowledge Of Farmyard Manure, Compost, Fertilizers And Other Agricultural By-Products And Their Applications Is Indispensable.The Present Book Is A Sincere Effort In Disseminating Information On Manures And Fertilizers. Primarily Designed As A Textbook, Its Wide Coverage Includes Varied Manures And Their Preparation And Effects; And Production And Consumption Of Various Fertilizers Along With The Detailed Elucidation Of Their Properties, Uses, Advantages And Disadvantages. Application Of Both Manures And Fertilizers Separately And In Combination Has Been Explained In Depth In Reference To Individual Crops Of Extensive Variety. It Analyses The Applied Aspects Of Fertilizers And Manures In Their Entirety And Suggests How To Adjust Them To Particular Soil And Particular Style Of Farming. The Book Is Well Supplemented With References And Indexes Which Will Prove Useful Study-Aids To Readers. Owing To Its Reader-Friendly Approach To The Subject, Simple Language And Lucid Style, The Book Is Accessible Even To Average Readers. While It Ideally Caters To The Academic Needs Of Undergraduate And Postgraduate Students Of Agriculture Science, It Is A Lasting Valuable Reference Source For Researchers And Teachers, Peasants, Geologists And Soil Surveyors.
