Root zone amendments are typically organic materials or inorganic materials of diverse mineralogy that when added to sand at modest rates of 5% to 20% by volume are capable of substantially and permanently altering the physical and chemical

, involving the establishment of mother vines from which dormant cuttings are taken for rooting or bench grafting, are relatively slow and not suited to rapid multiplication for commercial cultivation for newly released cultivars ( Singh et al., 2004 ). Mother

Acceptable physical properties are an integral part of root-media quality. However, there is no one growing medium that works best in all situations because root-media physical properties are not constant, but rather can be affected by the grower. Understanding the root environment under production conditions requires an understanding of the dynamic nature of air : water : solid ratio in the medium. The objective of this review is to consider key aspects of root-medium physical properties, which include bulk density and particle size, container capacity, media settling, water absorption, rewettability, moisture release characteristics, and water loss due to evaporation from the root-medium surface.

Koshimizu and Nishida (1949) measured LR branching in sweetpotatoes and postulated that LR branching may be very important “to supply the internal growth elements” for storage root formation. Pardales and Yamauchi (2003) studied sweetpotato LR

Black root rot (BRR) is a widespread disease of strawberry that causes the death of feeder roots and the degradation of structural roots resulting in an overall decrease in productivity ( Maas, 1998 ). By the 1950s, BRR had been reported in many

Root systems of most nursery-grown landscape trees extend well beyond the edge of the canopy. As a result, when large (greater than 2 m tall) field-grown trees are harvested for transplanting, only a small portion of the root system is moved and a
