  1. Session:By using green manure/cover crops, rural families can make sure theyhave enough calories, with or without droughts. By growing ediblegm/ccs (nearly all of which are leguminous, they can get enough proteins.By drying and storing the leaves of lablab beans or cowpeas, they can add to their...
  2. 01/01/1985 Green manure crops are crops that are [often times in North America] grown to be turned under to increase soil fertility. Leguminous green manure crops ( i.e., those which can make nitrogen fertilizers from atmospheric nitrogen) can offer small-scale Third World farmers a tremendous number of...
  3. 19/11/2019 Session :Green manure/cover crops are the only feasible way for smallholder farmers to significantly increase the organic matter content of their basic grain fields (that is, anything over 0.5 ha) at a reasonable cost. We can now say that we know of good species and systems that will work in...

    01/01/2014 Pour obtenir une productivité agricole élevée dans les tropiques au meilleur coût économique et écologique, il faut bien comprendre le rapport entre les nutriments présents dans le sol et la productivité des cultures. Pour ce faire, il nous faut remettre en question certaines idées reçues. La...

  8. 01/01/2012 Strong gradients of decreasing soil fertility are found in many regions of the world. Millions of smallholders are now facing this serious crisis which causes them lower crop yields, and many of these families also suffer from food insecurity. With the aim of promoting recovering soil fertility...
  9. 08/04/2016 Nous avons récemment reçu un rapport de Roland Bunch concernant ses efforts à promouvoir les engrais verts et les cultures de couverture en Afrique.
  10. 19/01/1995 Information about green manure and cover crop legumes.
  11. A group conversation with Roland Bunch about GMCCs that might be used in highland areas. For other presentations during the ECHO East Africa Highlands Symposium: http://edn.link/t4wnhf
  12. Session:The major factor in the increase in droughts across Africa has been caused mostly by the gradual death of fallowing, and the resulting decrease in rainwater infiltration from about 60% down to 20% in most areas. GM/CCs are the only feasible way to save Africa from the rapidly increasing...
  13. 20/10/2006 Development is a) a process of people learning to solve their own problems, b) sustainably. It means progressing from one problem to another. Agricultural development is possible in more ways and climates than people often think.
  14. 19/11/1997 Principles for increasing organic matter in order to increase soil fertility. Little by little, work in a dozen countries has convinced us that the vast majority of soils can be made highly fertile. How? By using our first principle:maximize organic matter production.

  16. Ressource principale 01/06/1995 Effective agricultural improvement work grows out of years and years of trying one approach after another, of searching constantly for new, more effective ways of working. Each new approach must not only be tried out, but must be evaluated on the basis of generous amounts of feedback from the...
