1. L'eau est l'un des principaux besoins des végétaux. Cependant, la pluviosité est insuffisante et irrégulière dans la plupart des régions arides et semi-arides. Dans ces régions, le taux d'évaporation est généralement élevé pendant la saison de croissance. Lorsqu'il pleut, les pluies sont...
  2. 01-01-1997 Water is one of the main requirements for healthy plant growth. Most arid and semi-arid regions, however, suffer from insufficient and unreliable rainfall. In these areas a high rate of evaporation in the growing season is also common. When it rains in (semi-)arid areas, the rainstorms are...
  3. Proceedings of a symposium/ sponsored by Divisions S-1 and S-3 of the Soil Science Society of America. This publication summarizes research in this important area. It will help in understanding microbial-soil environmental relationships as well as aid in managing soil and crops for human benefit....
  4. This SSSA Special Publication presents the outcomes from the symposium. Tomography is a very powerful tool for soil science research. Although tomography has not been widely used for soil science investigations, there are many potential applications of the technology. The papers in this Special...
  5. 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”...
  6. 20-10-2013 Does a planting basin, like a zai pit, make much of a difference in soil moisture on a sandy soil? Because water leaches through sand rather quickly, you might expect that planting depressions would not have a significant impact on soil moisture. With the soil in ECHO research plots in South...
  7. This short document contains graphs that show how zero tillage leads to increased water infiltration and increased water retention in soil.
