    Notes: Abstract The hydrological balances for the agroforestry systems of Theobroma cacao with Cordia alliodora or Erythrina poeppigiana were calculated using measurements taken over four years (1983–1987) of the following parameters: climatic (precipitation, evaporation); edaphological (texture, soil moisture tension, hydraulic conductivity, variations in soil moisture content). Water fluxes (interception, simulation of transpiration and percolation) were estimated from one year of measurements (1986–1987). Weekly samples of percolated water were taken from March 1986 – March 1987 using lysimetric capsules at 100 cm soil depth. N, P, K, Ca and Mg concentrations were determined to calculate the annual leaching losses. Nutrient concentration values were extrapolated for the whole 4 years observation period, in order to calculate leaching losses for the whole study period. Precipitation samples were also taken to determine the corresponding annual nutrient inputs.

    The CATIE experience in agroforestry teaching and training in Latin America (1994)
    Springer
    Agroforestry systems 28 (1994), S. 27-35

    ISSN: 1572-9680

    Notes: Abstract CATIE has been involved in agroforestry training at the MS level, short courses for professionals, and in-service training since 1976. Approximately one hundred MS degrees with theses in agroforestry subjects have been awarded during this period, and well over one hundred professionals have participated in short courses. Almost all of these activities have been funded by various short-term projects. Although CATIE has maintained a staff with experience in agroforestry research and training throughout this period, the dependence on short-term funding has resulted in changes in the personnel available to give courses. These changes have, however, to some degree reflected changes in the concepts of what areas within agroforestry should receive the greatest emphasis. The training program at CATIE has always maintained a strong on-farm orientation, but long-term experiments established at CATIE over the past twenty years are employed to give more basic training in research methodology.
