Assessing the impact of shallow subsurface pipe drainage on soil salinity and crop yield in arid zone.

ABSTRACT:

Purpose

Soil salinization is one of the key problems of sustainable development of arid agricultural land. Exploring the use of shallow subsurface pipe drainage to improve soil salinization.

Methods

This study investigates the desalinization effect of shallow subsurface pipe drainage, in combination with drip irrigation under plastic mulch, in an arid region in China. Field data collection was conducted in 2010. Soil salinity at a range of soil depths, water EC and pH of subsurface pipe drainage and crop yield during crop growth stages in salinized farmlands were measured.

Results and conclusion

The results show that soil salinity was reduced significantly on mildly (1-3 dS m^-1) and moderately (3-6 dS m^-1) salinized farmlands. The highest desalin
