How good is the turbid medium-based approach for accounting for light partitioning in contrasted grass–legume intercropping systems?

摘要

Background and AimsMost studies dealing with light partitioning in intercropping systems have used statistical models based on the turbid medium approach, thus assuming homogeneous canopies. However, these models could not be directly validated although spatial heterogeneities could arise in such canopies. The aim of the present study was to assess the ability of the turbid medium approach to accurately estimate light partitioning within grass–legume mixed canopies.
