Comprised of three sections, this important book provides detailed knowledge about the nutrient dynamics and productivity of global agroecosystems. The book explores agroecosystems that flourish in different continents of the world. The main focus is on the major aspects that make up agroecosystems, such as soils, climate, crops, nutrient dynamics, and productivity. The first section provides an introduction to agroecosystems and descriptions of global soil types that support vast crop belts.

In addition, there are 21 chapters that deal with wide range of agroecosystems that thrive around the globe, including Asia, Africa, the Americas, and more. Detailed descriptions on crop species and their origin, spread, genetic aspects, agroclimatic requirements, expanse, and productivity are provided for 32 important crops. The second section deals with the principles that drive crop growth, nutrient dynamics and ecosystematic functions within any agroecosystem. There are 7 chapters that deal with various aspects of nutrient dynamics in an agroecosystem. Several natural and man-made factors regulate development, sustenance, and productivity of agroecosystems. The third section covers the influence of agronomic practices and factors such as soil microbes, organic matter, crop genetic nature, irrigation, weeds, and cropping systems that affect productivity of agroecosystems.

This comprehensive volume will be useful to professors, researchers, and students dealing with agriculture, ecology, and geography. It also serves as a general reference book for all those interested in understanding our own nature and surroundings.
