A broad perspective, encompassing lucid descriptions of crop management towards higher yield and sustenance has been provided to the readers in this book. Agricultural production has a relation with physical problems which may not always be overcome by technology. However, one can see better groomed farms flourishing and consistently making greater profits as compared to similarly structured, neighboring farms under similar conditions. For every abiotic condition, it is well-known that there is a difference between the potential and observed yields, which is generally high and often could be cut down through better management techniques. This book discusses agricultural problems encountered in different regions of the world which were resolved using innovative methods, presenting new approaches for well-known techniques and new tools for old problems.
