Below-ground interactions in tropical agroecosystems: concepts and models with multiple plant components.

Book cover for Below-ground interactions in tropical agroecosystems: concepts and models with multiple plant components.

Description

This book provides a synthesis of plant-soil-plant interactions from the plot to landscape scale. It focuses on the process level, which is relevant to many types of multispecies agroecosystems (agroforestry, intercropping and others). It also links basic research to practical application (and indigenous knowledge) in a wide range of systems with or without trees, and considers implications of bel...

Catching and competing for mobile nutrients in soils.

This paper discusses the factors determining nutrient transport in, and losses from, soil solutions (in uniform and heterogeneous soil conditions), and investigates ways to describe how plants compete for nutrients or act as safety nets (in the form of cation and anion retardation mechanisms), with examples from recent research. The scope of WANULCAS (water, nutrient, light capture in agroforestry systems) model which describes the flow of water through macropores that bypasses the soil solution contained in the soil matrix, is given. Sensitivity analysis of the impact of macroporosity on hedgerow intercropping systems in Lampung, Indonesia is provided. In addition, the below-ground competition in HYPAR which models the growth of trees and crops in agroforestry systems is discussed.
