Contribution of agroforestry trees to nutrient requirements of intercropped plants,were previously grown. Recently objective analyses and controlled experiments have addressed this topic. This paper examines the issues of tree prunings containing sufficient nutrients to meet crop demands, the timing of nutrient transfer from decomposition to intercrops, the percent of nutrients re

Tree root characteristics as criteria for species selection and systems design in agroforestry,empts to identify root-related criteria for the selection of agroforestry tree species and the design of agroforestry systems. Tree roots are expected to enrich soil with organic matter, feed soil biomass, reduce nutrient leaching, recycle nutrients from the subsoil below the crop rooting zone and i

Root architecture in relation to tree-soil-crop interactions and shoot pruning in agroforestry,lopment may enhance nutrient capture and transfer to subsequent crops via organic pools. In simultaneous systems tree root development in the crop root zone leads to competition for resources..Fractal branching models provide relationships between proximal root diameter, close to the tree stem, and

A model simulating above- and below-ground tree architecture with agroforestry applications, the development sequence of a tree is studied by the identification of various levels of organisation and of homogeneous subunits. All of these — architectural unit, axis, growth unit — follow particular growth processes which can be described by using the second approach, the quantitative analysis

Incorporation of indigenous knowledge and perspectives in agroforestry development,ogy at a front-line agricultural research centre in the eastern mid-hills of Nepal. Sophisticated knowledge of tree-crop interactions and the feeding value of various tree fodders was revealed. Farmers’ ecological knowledge was more developed in some areas than others and was largely complementary t

The use and value of multiple methods to capture the diversity of endogenous agroforestry knowledge the identification and characterization of farmer agroforestry experts will illustrate the necessity of multiple methods. Nonformal, participatory methods were employed to identify the research subjects (farmer agroforestry experts) and to gain insights into the emic conception and understanding of
