To Receive

The dry drainage system (DDS) is an alternative technique for controlling salinization. To quantify its role in soil salinity control, a five-year field observation from 2007 to 2011 was completed in a 2900 ha experimental plot in Yonglian Experimental Station, Hetao Irrigation District, China. Results showed that the groundwater table depth in the fallow areas quickly responded to the lateral recharge from the surrounding croplands during irrigation events. The groundwater electrical conductivity (GEC) of fallow areas increased from 5 mS·cm−1 to 15 mS·cm−1, whereas the GEC below croplands produced small fluctuations. The analysis of water and salt balance showed that the excess water that moved to fallow was roughly four times that moved by an artificial drainage system and with 7.7 times the corresponding salt. The fallow areas act as a drainage repository to receive excess water and salt from surrounding irrigated croplands. Slight salt accumulation occurred in irrigated croplands and salts accumulated, with an accelerating trend over the final two years. The evaporation capability weakened, partly due to the salt crust in the topsoil, and the decrease in soil permeability in the soil column, which was almost impermeable to water. Using halophytes may be an effective method to remove salts that have accumulated in fallow areas, having great economic and ecological value. A DDS may be effective and sustainable in situations where the fallow areas can sustain an upward capillary flux from planted halophytes.

The introduction of watertable control by groundwater pumping on a salt-affected dairy farm in the Goulburn Valley resulted in large increases in butter fat production. Since intensive pumping started, in 1981, watertable levels showed an overall downward trend but were still subject to major fluctuations caused by irrigation and rainfall. During this period butterfat production increased from about 300 to 390 kg/ha (of productive land) and yearly pasture production rose from about 560 to 650 t/ha DM. These productivity increases are attributed to both a reduction in average soil salinity in the top 60 cm of the profile from 2400 to 1200 mg total dissolved salts per kg dry soil and an increase in irrigation water use from less than 10 M litre/ha before to nearly 12 M litre/ha after pumping started.
