✦ Synopsis

The distribution of elongation and surface pH patterns along the primary roots of maize (cv. LG 11), maintained vertically in humid air (darkness, 22 ~ C), have been analysed quantitatively. A new technique employing Sephadex G 25 beads containing a pH indicator dye (bromocresol purple), was used for measuring both the growth gradient of the roots (Sephadex beads as markers) and at the same time, the surface pH changes (referring to a standard scale). The optimal axial growth was located between 2 and 4 mm from the tip. This coincides with the optimal decrease in surface pH.

## ABSTRACT The pattern of distribution of nutrients in maize varied with the method of irrigation used for winter wheat. The major nutrient uptake zone was concentrated closer to the soil surface in fields irrigated with sprinklers than in surface‐irrigated fields, especially in dry years, which l
