  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...

  3. Key Resource 2014-01-01 In order to achieve high levels of agricultural productivity in the tropics at the lowest possible economic and ecological costs, we need to properly understand the relationship between nutrients in the soil and crop productivity. For this to happen, the current understanding needs to change. The...
  4. 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...
  5. Key Resource 2019-05-21 Now available through Amazon as well as the ECHO Bookstore Smallholder farmers around the world face some of the harshest growing conditions globally, yet they produce the majority of the world’s food. Soils in these areas often lack nutrient and water holding capacities, due to erosion or poor...
  6. 2012-01-01 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...
  7. 2016-04-08 A report from Roland Bunch regarding his efforts to promote green manures and cover crops in Africa.
  8. 1995-01-19 Information about green manure and cover crop legumes.
  9. 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
  10. 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...
  11. 2006-10-20 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.
  12. 1997-11-19 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.
  13. Biographical information:Ken Giller,Professor of Plant Production Systems, Wageningen University -joined Wageningen in 2001 after holding professorships at Wye College, University of London, and the University of Zimbabwe. He currently heads up a multifaceted project,N2Africa, which puts nitrogen...
  14. Key Resource 1995-06-01 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...

  16. 1985-01-01 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...
