Preliminary Column Experiment on Dynamics of Water and Ion Transport in Soil Affected by Root Absorption

The Pattern of Root Distribution and Water Absorption in Layered Soil

The pattern of root distribution in layered soils is one of the significant issues in the calculations of soil water and irrigation management and planning. The objective of this study was to determine the pattern of root distribution of soybean in layered soils and its effect on water uptake. The research was conducted in a completely randomized design with 15 treatments consisting of three di...

Modelling Root System Phosphate Uptake from a Soil Column as Affected by Root Exudation

Effects of deficit irrigation and groundwater depth on root growth of direct seeding rice in a column experiment

Rice is an essential crop in Iran that is grown mostly in areas where depth to groundwater is low. Root growth and water uptake of rice under shallow groundwater has not been thoroughly studied. This experiment was conducted to determine the lowland rice (cv. Ghasrodashti) root distribution above shallow groundwater in relation to deficit irrigation and groundwater depth in cylindrical gre...

Dependence of Prolonged Water Absorption by in Vitro Locust Rectum on Ion Transport

1. An in vitro preparation of the locust rectum, consisting of an everted cannulated sac, is described. After the first hour, the rates of ion and water transport, the electropotential difference and tissue volume do not change significantly over the next 4 h, i.e. a steady-state situation is approximated. 2. The activities and properties of these rectal sacs are reasonably similar to those in ...
