Soil and Fertilizers: Managing the Environmental Footprint presents strategies to improve soil health by reducing the rate of fertilizer input while maintaining high agronomic yields. It is estimated that fertilizer use supported nearly half of global births in 2008. In a context of potential food insecurity exacerbated by population growth and climate change, the importance of fertilizers in sustaining the agronomic production is clear. However, excessive use of chemical fertilizers poses serious risks both to the environment and to human health. Highlighting a tenfold increase in global fertilizer consumption between 2002 and 2016, the book explains the effects on the quality of soil, water, air and biota from overuse of chemical fertilizers. Written by an interdisciplinary author team, this book presents methods for enhancing the efficiency of fertilizer use and outlines agricultural practices that can reduce the environmental footprint. Features: Includes a thorough literature review on the agronomic and environmental impact of fertilizer, from degradation of ecosystems to the eutrophication of drinking water Devotes specific chapters to enhancing the use efficiency and effectiveness of the fertilizers through improved formulations, time and mode of application, and the use of precision farming technology Reveals geographic variation in fertilizer consumption volume by presenting case studies for specific countries and regions, including India and Africa Discusses the pros and cons of organic vs. chemical fertilizers, innovative technologies including nuclear energy, and the U.N.’s Sustainable Development Goals Part of the Advances in Soil Sciences series, this solutions-focused volume will appeal to soil scientists, environmental scientists and agricultural engineers.

Organic manure is the decomposition product of dead plant and animal residues, which is added to soil to enrich soil fertility. All the decomposable residues can be made into manure including human and animal excreta. Manures, Fertilizers and Soil Fertility is a comprehensive textbook comprising of eleven chapters that cover the prime areas comprise of manures, fertilizers and soil fertility, thoroughly covering the syllabus, sequentially arranged, which imparts broad knowledge on three important areas of soil fertility management viz., manures, fertilizers and soil fertility. This book will be useful for undergraduate students in the field of soil fertility and its management at various agricultural/horticulture universities.

Excerpt from Fertility of Soils as Affected by Manures The use of manures as a means of increasing the growth of crops dates back to ancient times. At the time of the discovery of America, the North American Indians used dead, fish as a manure for corn. The Peruvians have used guano since the beginning of their recorded history, and the Chinese have long recognized the value of all kinds of excrements as fertilizers. In the early part of the last century De Saussure established the existence of the mineral constituents Of the' soil in plants, and while he believed that they Were essential to the life of plants, his contemporaries regarded them as nonessential, or at the best useful only as a kind of Stimulant.
