Root zone salinity management using fractional skimming wells with pressurized Irrigation: proceedings of the Year-End Seminar 2001
In the short water supply environment of Pakistan, fanners try to minimize the gap between demand and supply of canal water by extracting groundwater for irrigation purposes. However, saline groundwater upconing may occur in response to fresh groundwater withdrawals from unconfined aquifer underlain by salty groundwater. Skimming well technology can help in control1ing this upconing phenomenon. However, in most cases, the small discharges of such wells cannot be efficiently applied on surface irrigated croplands. Pressurized irrigation systems use smal1 discharge effectively, but the cost and availability of equipment in the local market are the constraints. Root zone salinity is also expect...
. Root zone salinity management using fractional skimming wells with pressurized Irrigation: proceedings of the Project-End Workshop 2003
Detailed hydro-geological investigations were carried out while implementing SCARPs in the Chaj Doab. These investigations yielded a data set of groundwater quality at different depths of the aquifers (spatial) especially in the SCARP-II saline zone. In MREP area, 138 public tubewells, having strainers from 30-35 m till 60-75 m depth of the aquifer, were installed during the 1970s to help meet the irrigation water demand at farm level. The MREP, who was made responsible for operation and maintenance of these deep tubewells, continuously monitored the performance of these tubewells as well. Therefore, the pumped groundwater quality data (temporal) of these spatially distributed tubewells was ...

Sustainable Plant Nutrition under Contaminated Environments
Global industrial growth has resulted in numerous pollutants being introduced into the environment. It has additionally caused decreased water availability for agricultural activity in developing countries, which, in turn, has compelled farmers to use wastewater irrigation. In advanced agricultural systems, farmers are adapting various strategies to achieve a higher yield and thus sustain crop productivity. Consequent to the introduction of contaminants in the environment, soil pollutants have become a critical issue. Selection of disease-resistant, high-yielding crop varieties, and extensive fertilizer applications are quite common among farming communities. This book provides insight into environmental pollutants with special reference to their interference with plant nutrition. It additionally discusses the physiological aspects of plant nutrition. This book enhances current knowledge of the effects of pollutants on plant growth and physiology.
