One of the main approaches for safeguarding food security,
sustainable development has increased demand for knowledge on
fertilizer management in crop production. Among essential plant
nutrients, nitrogen is one of the most important yield-limiting
nutrients, mainly responsible for determining yield and yield
components in cereals and legumes. It is also responsible for the
activation of many enzymes and, of course, plays an important role
in photosynthesis. With a recovery efficiency of less than 50
percent in most cropping systems, a large portion of the nitrogen
applied as fertilizer is not used by plants, creating environmental
and economic issues. Nitrogen Management in Crop Production covers
the critical aspects for the judicious use of nitrogen in cropping
systems. This includes appropriate methods of nitrogen application,
effective source and timing of application during crop growth
cycles, use of an adequate application rate to avoid loss and
reduce cost, use of nitrogen-efficient crop genotypes, and use of
legumes that fix sufficient amounts of atmospheric nitrogen. There
is also a chapter on organic matter and its role in sustainability.
This book presents recent information from the international
literature, making it relevant for most agroecological regions.
Chapters provide experimental results to aid in practical
application of the information. The book contains color photos of
nitrogen deficiency symptoms to serve as a guide for important crop
species, such as rice, dry bean, wheat, soybean, and corn. It also
includes numerous tables and figures, providing an easy-to-read
reference.
