The cropping system is one of the important components of
sustainable agriculture, since it provides more efficient nutrient
cycling. As such, balanced fertilization must be based on the
concept of sustainable crop production. Feeding the rapidly growing
world population using environmentally sustainable production
systems is a major challenge, especially in developing countries. A
number of studies have highlighted the fact that degradation of the
world's cultivated soils is largely responsible for low and
plateauing yields. Soil is lost rapidly but only formed over
millennia, and this represents the greatest global threat to
nutrient dynamics in agriculture. This means that nutrient
management is essential to provide food and nutritional security
for current and future generations. Nutrient dynamics and soil
sustainability imply the maintenance of the desired ecological
balance, the enhancement and preservation of soil functions, and
the protection of biodiversity above and below ground.
Understanding the role of nutrient management as a tool for soil
sustainability and nutritional security requires a holistic
approach to a wide range of soil parameters (biological, physical,
and chemical) to assess the soil functions and nutrient dynamics of
a crop management system within the desired timescale. Further,
best nutrient management approaches are important to advance soil
sustainability and food and nutritional security without
compromising the soil quality and productive potential. Sustainable
management practices must allow environmentally and economically
sustainable yields and restore soil health and sustainability. This
book presents soil management approaches that can provide a wide
range of benefits, including improved fertility, with a focus on
the importance of nutrient dynamics. Discussing the broad impacts
of nutrients cycling on the sustainability of soil and the cropping
systems that it supports, it also addresses nutrient application to
allow environmentally and economically sustainable agroecosystems
that restore soil health. Arguing that balanced fertilization must
be based on the concept of INM for a cropping system rather than a
crop, it provides a roadmap to nutrient management for
sustainability. This richly illustrated book features tables,
figures and photographs and includes extensive up-to-date
references, making it a valuable resource for policymakers and
researchers, as well as undergraduate and graduate students of Soil
Science, Agronomy, Ecology and Environmental Sciences.
