Soil Fertility


This is a non-credit bearing course under AGRI SETA. Duration: 4 days


Concerns are growing about long-term sustainability of agriculture. Fertile land and sufficient water are vital for sustaining agriculture and livelihoods. In Africa productivity of land, however, has been decreasing with the increasing intensification of agriculture due to land degradation. The major causes of land degradation are unsustainable agricultural practices like farming on steep slopes without sufficient use of soil and water conservation measures, mono cropping, excessive tillage, or declining use of fallow without appropriate replenishment of soil nutrients, burning of crop residues, conversion of forests, woodlands and bush lands to permanent agriculture, or their excessive exploitation through fuel wood and timber harvesting, overgrazing of rangelands, and lack of proper soil organic matter management.


Upon completion one would be able to:

  • Get familiar with local soils and their characteristics.
  • Understand that soil fertility management is neither limited to the addition of fertilizers nor to increasing crop yield alone. It consists, first of all, of protecting the soil and enhancing its organic matter content as well as its biological activity to prevent loss of soil and encourage optimal nutrition, water supply and health of plants, increase yields and maintain yield consistency.
  • Know the tools of organic soil fertility management and be able to combine them in an appropriate way so as to correspond to local conditions and needs of the crops.
