Lead phytoextraction by wheat in response to the edta application method
Lead solubilization in soil and accumulation by spring wheat (Triticum aestivum L.) was studied in response to the ethylenediaminetetraacetic acid (EDTA) application method. In this study, 4 mmol EDTA kg−1 was applied using ...
Disposal and Use of Sewage on Agricultural Lands in Pakistan: A Review
Raw sewage is widely used on agricultural soils in urban areas of developing countries to meet water shortages. Although it is a good source of plant nutrients, such sewage also increases the heavy metal load to soils, ...
Optimizing the rate and timing of phosphogypsum application to magnesium-affected soils for crop yield and water productivity enhancement
The levels of magnesium (Mg2+) in irrigation waters and soils are increasing in several irrigation schemes worldwide. Excess levels of Mg2+ in irrigation waters and/or in soils negatively affect soil physical properties ...
Mulching and water quality effects on soil salinity and sodicity dynamics and cotton productivity in Central Asia
Water scarcity and the predicted impact of climate change will necessitate the use of alternate available water resources in agriculture, such as saline water, to narrow the gap between demand and supply of freshwater. ...
Turning Environmental Burdens into Economic Opportunities
Analysis of the global water cycle yields some encouraging numbers, with annual per capita renewable water supply about 7000 m3 (7 million liters). However, some countries have as little as 500 m3 per capita, with periodic ...
Sustainable Management of Saline Waters and Salt-Affected Soils for Agriculture: Proceedings of the Second Bridging Workshop
Irrigation plays an important role in crop production and agricultural development in arid and semi-arid regions. The area of irrigated land in these regions has expanded substantially, particularly in the second half of ...
