Book 2003ition, water and solute movement, and for their responses to three major abiotic stresses, i.e. hard soil structure, drought and flooding. The volume concludes with the interactions of roots with other organisms of the complex soil ecosystem, including symbiosis, competition, and the function of roots as a food source..

Turnover of Root Systems,hompson 1982; Coughenour 1985; Milchunas et al. 1988). In the case of deciduous trees, turnover of the canopy is 100% per year. Similarly, grasses in seasonal environments often have essentially 100 % canopy turnover per year.

Root Exudates: an Overview,tides, tannins, steroids, terpenoids, alkaloids, polyacetylenes, and vitamins (Table 10.1; Rovira 1969; Sch?nwitz and Ziegler 1982; Rice 1984; Uren 2000). Uren (2000) suggested that the amount of root exudates produced varies with the plant species, cultivar, the age of the plant, and substrate and stress factors.

Root Growth and Function in Relation to Soil Structure, Composition, and Strength, and a complex multi-scaled network of three-dimensional pore space. Soil strength and physical conditions can exert a major constraint to root growth. Hard soils with massive structures restrict the accessibility of nutrients and water to plants. In many laboratory and glasshouse experiments, and i
