Movement of potato root diffusate through soil.
Movement of potato root diffusate (PRD) through soil was examined by using the hatch of eggs from Globodera rostochiensis cysts as an indicator. Porous bags containing cysts were placed at increasing distances and depths from potato roots, whose growth was restricted by nylon mesh. Significantly greater hatch was observed up to 50 cm laterally away from potato roots, compared with hatch in fall...
متن کاملBehavior of Compacted Lime-soil Columns
This study presents the results of large scale laboratory model tests to investigate the behavior of Compacted Lime – Well-graded Soil (CL-WS) rigid stone columns in soft soils. The unit cell idealization is used for construction of composite specimens by evaluating the influence of different parameters such as the diameter of the column (D), the slenderness ratio (L/D) and the area ratio (Ar)...
متن کاملMovement of Arsenic in undisturbed Soil Columns with Irrigated Rice Culture
Introduction Arsenic from irrigation water is accumulating in soils (Ullah, 1998; Panaullah et al., 2003). The presence of high As in Bangladeshi soils and continuing use of As contaminated irrigation water may affect the movement of As in soil and accumulation of As in rice (Abedin et al., 2002). Transport of As in soil, as well as uptake by plants is governed by mobility, yet mobility of As i...
متن کاملUptake in Vegetated Soil Columns
Investigations are currently being conducted at Imperial College into the upward migration of radionuclides from a contaminated water table and their subsequent uptake by plant root systems. This programme includes both experimental studies and related mathematical modelling. Previous work has been primarily with lysimeters. However, these experiments are expensive and somewhat lengthy and the ...
متن کاملSolute Movement in large Soil Columns under different Water Flow Velocities
Soil-water flow velocity can be a major factor affecting ion movement in the soil matrix. The transport of both cations and anions and their interactions with soil surface affect many aspects of soil management such as wastewater disposal, saline soil reclamation, remediation of sodic soils, and soil decontamination (HENG et al., 1999a). Therefore it is important to understand the processes tha...
