Nitrogen is an essential plant nutrient which is considered as a mineral
element. Nitrogen deficiency reduces the fertility of the soil and
affects the crop production severely. Plants absorb nitrogen through
their roots in the form of nitrate and ammonium ions. It plays a crucial
role in photosynthesis and is responsible for the activation of various
enzymes. Nitrogen based fertilizers are the most important means of
nitrogen management. They play an important role in the areas with
prolonged wet field conditions which makes the soil nitrogen deficient.
However, excess nitrogen in the soil can cause nitrogen pollution.
Alternative nitrogen sources such as organic residues and biological
nitrogen fixation could be used to manage nitrogen effectively and
increase the crop yield while reducing the harmful effects on the
environment. The various studies that are constantly contributing
towards advancing technologies and evolution of this field are examined
in detail. Also included herein is a detailed explanation of the various
concepts and applications of nitrogen management in crop production. For
all those who are interested in crop production, this book can prove to
be an essential guide.
