The effect of mineral-ion interactions on soil hydraulic conductivity

Buelow, Maya C.; Steenwerth, Kerri; Parikh, Sanjai J. - In: Agricultural Water Management 152 (2015) C, pp. 277-285

The reuse of winery wastewater (WW) could provide an alternative water source for vineyard irrigation. The shift of many wineries and other food processing industries to K+-based cleaners requires studies on the effects of K+ on soil hydraulic conductivity (HC). Depending on clay content and...

The effect of saline shallow ground and surface water under deficit irrigation on (Carthamus tinctorius L.) in semi arid condition

Ghamarnia, Houshang; Gholamian, Mohsen - In: Agricultural Water Management 118 (2013) C, pp. 29-37

A number of column experiments were conducted in order to determine groundwater contributions by safflower (Carthamus tinctorius L.) under different saline shallow groundwater (Gw), surface water (Sw) and deficit irrigation schemes. The plants were grown in 16 columns with 0.40m diameter and...

Water availability determines hydrological impact of tree belts in dryland cropping systems

Brooksbank, K.; Veneklaas, E.J.; White, D.A.; Carter, J.L. - In: Agricultural Water Management 100 (2011) 1, pp. 76-83

Shallow groundwater can often develop when perennial ecosystems are replaced by annual agriculture. Returning trees to these landscapes is one option available to farmers to use more of the incident rainfall and stop the rising water table before it begins to affect production of the...
