As part of its efforts to improve fertilizer use and efficiency in
West Africa, and following the recent adoption of the West African
fertilizer recommendation action plan (RAP) by ECOWAS, this volume
focuses on IFDC's technical lead with key partner institutions and
experts to build on previous and current fertilizer recommendations
for various crops and countries in West Africa for wider uptake by
public policy makers and fertilizer industry actors.

Food insecurity is a fundamental challenge to human welfare and
economic growth in Africa. Low agricultural production leads to low
incomes, poor nutrition, vulnerability to risk and threat and lack
of empowerment. This book offers a comprehensive synthesis of
agricultural research and development experiences from sub-Saharan
Africa. The text highlights practical lessons from the sub-Saharan
Africa region.
The book gives a detailed description of the application of DSSAT
in simulating crop and soil processes within various
Agro-ecological zones in Africa. The book, an output of a series of
3 workshops, provides examples of the application of DSSAT models
to simulate nitrogen applications, soil and water conservation
practices including effects of zai technology, phosphorus and maize
productivity, generation of genetic coefficients, long-term soil
fertility management technologies in the drylands, microdosing,
optimization of nitrogen x germplasms x water, spatial analysis of
water and nutrient use efficiencies and, tradeoff analysis. The
minimum dataset requirements for DSSAT is discussed. This book
arises from attempts to address the limited use of models in
decision support by African agricultural (both soil scientist and
agronomists) scientists.
This book elucidates the importance of long-term experiments in
revealing evidence of soil fertility decline in Africa. An
evaluation of experiences from on-going long-term experiments is
given in broad detail. The first chapter explains the paradigm
shift in soil fertility management then provides justification for
long-term experiments before illuminating experiences from
long-term experiments in East, West and Southern Africa. The
second, sixth, eighth and ninth chapters give an in-depth account
of crop management practices and soil fertility interventions in
long-term trials within specific agro-ecological zones in West
Africa. The rest of the chapters (chapter three, four, five and
seven) address crop management, tillage practices and, organic and
inorganic fertilizer applications in the context of long-term
experiments in specific agro-ecological zones in East Africa.

Legumes play an important role in the cropping systems of sub
Saharan Africa (SSA). Legumes are an important source of nutrition
to both humans and livestock by providing the much needed protein,
minerals, fibre and vitamins. The sale of legumes seed, leaves and
fibre generates income for the marginalized communities especially
women. Cultivation of legumes is essential for the regeneration of
nutrient-deficient soils. By biologically fixing nitrogen (BNF) in
the soil, legumes provide a relatively low-cost method of replacing
otherwise expensive inorganic nitrogen in the soil. This enhances
soil fertility and boosts subsequent cereal crop yields. Production
of legumes in SSA is however; hampered by a number of constraints
among them low and declining soil fertility, low soil pH, high
salinity, drought and flooding, poor access to improved germplasm,
diseases, pests and weeds. Farmers need to learn how to overcome
these constraints if the full benefits of legumes are to be gained.
This book presents a synthesis of research work on legumes and
draws attention to the importance of legumes in integrated soil
fertility management (ISFM) and poverty alleviation in SSA.
This book brings together the essential evidence and policy
opportunities regarding the global importance of soil carbon for
sustaining Earth's life support system for humanity. Covering the
science and policy background for this important natural resource,
it describes land management options that improve soil carbon
status and therefore increase the benefits that humans derive from
the environment. Written by renowned global experts, it is the
principal output from a SCOPE rapid assessment process project.
