With the use of high-level soil management technology, Africa could
feed several billion people, yet food production has generally
stagnated since the 1960s. No matter how powerful the seed
technology, the seedling emerging from it can flourish only in a
healthy soil. Accordingly, crop yields in Africa, South Asia, and
the Caribbean could be doubled or tripled through adoption of
technologies based on laws of sustainable soil management.
Principles of Sustainable Soil Management in Agroecosystems
describes the application of these laws to enhance ecosystem
services while restoring degraded soils and promoting sustainable
use. With chapters contributed by world-class soil scientists,
ecologists, and social scientists, this book outlines critical
changes in management of agricultural soils necessary to achieve
food security and meet the food demands of the present and
projected future population. These changes include conversion to
no-till and conservation agriculture; adoption of strategies of
integrated nutrient management, water harvesting, and use of drip
sub-irrigation; complex cropping/farming systems such as cover
cropping and agroforestry; and use of nano-enhanced fertilizers.
The book is based on the premise that it is not possible to extract
more from a soil than what is put into it without degrading its
quality. The strategy is to replace what is removed, respond wisely
to what is changed, and be pro-active to what may happen because of
natural and anthropogenic perturbations. The chapters, which
exemplify these ideas, cover a range of topics including organic
farming, soil fertility, crop-symbiotic soil microbiota,
human-driven soil degradation, soil degradation and restoration,
carbon sink capacity of soils, soil renewal and sustainability, and
the marginality principle.
