Agriculture in Africa: challenges
 Poor soil fertility, drought
 Low productivity
 Fertilizer use: lowest in the world
 High transport costs
 Small markets
 Food imports (SSA, bln $)

Where are the drylands?

And fertilizer use in the region
remains low (kg nutrients/ha)

IFDC
Now: Integrated Soil Fertility Management
A set of soil fertility management practices that
necessarily include the use of fertilizer, organic
inputs, targeted interventions to improve soil
“hospitability” (drought, acidity) and improved
germplasm combined with the knowledge on how
to adapt these practices to local conditions, aiming
at optimizing agronomic use efficiency of the
applied nutrients and improving crop productivity.
All inputs need to be managed following sound
agronomic and economic principles.
IFDC
Integrated Soil Fertility Management (ISFM)
Optimal use of:
 Soil nutrients
 Locally available soil
amendments
 Mineral fertilizers
 Improve soil “hospitability”
Improve crop productivity, while

Concluding Remarks
IFDC
For ISFM to fulfill the promises in SSA the following are
essential:
 Innovation systems, extensions tools and systems to be
established
 Increased farmers access to inputs (fertilizer, seed, organic
resources, etc.…)
 Capacity building of R&D staff and institutions to address diversity,
complexity and emerging global issues
 Technological and processes innovations to improve nutrient use
and water use
