1. ทรัพยากรหลัก 01-03-1991 This book looks as methodologies for screening soil-improving legumes such as how to replenish nitrogen, which is often the limiting nutrient to plan growth, farmers in many cultures grew green manures, living crops whose primary purpose was to add nitrogen or organic matter to the soil.
  2. ทรัพยากรหลัก 28-07-2004 In the 1980s and 1990s, green manure/cover crop (GMCC) systems became a popular agricultural technology in research and development efforts for smallholder tropical and subtropical farmers. However, few syntheses of these experiences have been conducted. This volume of case studies contributes...
  3. ทรัพยากรหลัก 01-01-1993 3 Copies For developing nations, soil erosion is among the most chronic environmental and economic burdens. Vast amounts of topsoil are washed or blown away from arable land only to accumulate in rivers, reservoirs, harbors, and estuaries, thereby creating a double disaster: a vital resource...
  4. ทรัพยากรหลัก 01-10-1974 Soils play a critical role in meeting human food needs. Their conservation and wise use are essential today and will be even more critical in the future as population pressures increase. These pressures are already forcing the use of lands for food production that good judgment says should be...
  5. ทรัพยากรหลัก 01-03-2001 Lessons learned in Latin America is about the use and dissemination of cover crops in different agroecosystems need to be made more widely available not only to Spanish speaking, but also Anglophone regions. This publication aims to inform a wide range of actors involved in rural development...
  6. 01-11-2016 Cover crops play a key role in sustainable agriculture by providing sustainable sources of nutrients as well as protective soil cover to minimize erosion and reduce moisture stresses. Examples of successful cover cropping systems in East Africa will be illustrated as well as constraints and...
  7. Ed : While not dealing specifically with tropical crops, some of the management situations discussed can be adapted for consideration in other contexts. Farmers around the country (US) are planting cover crops on millions of acres to protect and improve the soil, and the more that farmers use...
  8. 19-10-1994 The use of cover crops in orchards and plantations. Since the early 1900s legumes have been used as cover crops in oil palm plantations in Asia. More recently it is being evaluated for other trees: soursop (Annona muricata) in Costa Rica, citrus in Honduras and Surinam, bananas in Panama, etc....
  9. 20-04-2014 EDN 122 highlighted multi-purpose cowpea varieties with spreading vines that cover the soil. Below is an ECHO research update from South Africa relating our experience so far with a spreading cowpea variety intercropped with maize grown in a Foundations for Farming (FFF) system. “Living carpet”...
