Modelling Root System Growth and Architecture, for synthesising knowledge to produce more global representations and for testing hypotheses on the interacting mechanisms derived from experimental results. The models presented here are mainly devoted to a description of the kinetics of root system development and the spatial arrangement of roots

BLOT

Sampling Strategies, Scaling, and Statistics,allocated to the root system, and it is the roots that absorb most nutrients and water (Russell 1977). The property of the root system which is most appro-priate to measure depends on the objective of the experiment. Root length should be measured to calculate the inflow rate of water and nutrients

TIGER

Auger Sampling, Ingrowth Cores and Pinboard Methods, in which they grew. Some of these methods are included in previous reviews (Kolesnikov 1971; Böhm 1979). The methods are either disruptive or totally destructive to the root system being studied and to the immediate environment (Taylor et al. 1991).

Root Observations and Measurements at (Transparent) Interfaces with Soil,oot windows” and “minirhizotrons” (transparent glass or plastic tubes pushed into the soil: Bates 1937), through which roots are observed non-destructively in situ at the interface between the glass and the soil. The possible observations include recording root growth and decay — processes which are
