“…This could be due to good drainage and solubilization of in situ CaCO 3 that increased the electrolyte concentration of soil solution in these soils. Soil physical properties such as texture and environmental conditions such as high evapo‐transpiration in the study site could also affect accumulation of Na + within the root zone (Burrow et al ., 2002). Higher clay content in soils provide more exchange sites for Na + and thus aid in its build up.…”

Development of alternative sources through wastewater reuse is important to meet water demands in arid regions. However, effects of wastewater irrigation on soil properties and crop performance must be evaluated before advocating its widespread use. Objectives of this study were to evaluate: (i) effects of prior evaporative disposal of saline-sodic blowdown water (BW) on soil (fine-loamy, mixed, and thermic Typic Calciorthods) properties in the disposal area, and (ii) effects of flood irrigation with three water qualities (control, BW 1X, and BW 2X) on soil salinity and alfalfa performance using a greenhouse soil column study (soil collected from same study area as objective (i)). Results indicated that although prior land disposal of BW had increased salinity and sodicity of soil, they were within the tolerance limits of the intended crop, alfalfa. Mass balance calculations indicated measured (15Á6 Mg ha À1 ) and calculated (13Á2 Mg ha À1) salt accumulation at the test site used for evaporative disposal were similar. Alfalfa grown using BW under greenhouse conditions produced prime quality hay and biomass yield similar to the control treatment (8Á3 g column À1 vs. 10Á5 g column À1 in control). Although 3Á6 years equivalent of flood irrigation with BW 1X did not result in saline soil (BW 1X irrigated soils EC ranged from 2Á2 to 3Á5 dS m À1 ), BW 2X irrigation resulted in saline soils. Sodicities of irrigated soils were greater in fine textured deep soils than coarse textured surface soils (e.g., SAR of 6Á1 at 0-5 cm vs. 19Á5 mmol 1/2 L À1/2 at 30-60 cm in BW 1X), indicating the need for high solubility Ca amendments for long-term irrigation with BW on fine texture soils within the soil profile.

“…clay particles, minerals, organics) undergo leaching through the soil profile, accumulating and blocking deeper macro/micro pores, especially in textured-heavier soil layers, and finally causing waterlogging (e.g. Burrow et al [86]. Thus, salt-affected soils (profiles) depleted in adsorption matrices (organic matter and clay content notably) might be more prone to mobility and transfer of certain pollutants (e.g.…”

Global Wheat Production

With the projection of the Earth's population reaching eight billion in coming years and nine billion by 2050 which means increasing demand for food. Wheat (Triticum aestivum L.) is the main important and strategic cereal crop for feeding the majority of world's populations. Scientific forecasts predict that wheat production in the future will be affected by climate change and will decrease on the global level. To reduce these risks, the impact of climate change mitigation strategies and management systems for crop adaptation to climate change conditions should be considered. Demand for increases in food production will have to occur on less available arable land, which can only be accomplished by intensifying production. Chemical fertilisers are responsible for 40-60% of the world's food production. Because nonlegume plants generally require 20-50 g of nitrogen to produce 1 kg dry biomass, the natural supply of soil nitrogen usually restricts plants yield in most agricultural cropping system. The goal of ecological intensification is to increase yield per unit of land, intensify production, while meeting acceptable standards of environmental quality. This chapter discusses some aspects of connection between nitrogen supply and different abiotic conditions.

“…Differences between SAR values of lysimeter soil solution samples and saturated paste extracts were not significant; however, it is evident from table 4 that SAR values are generally greater in near surface horizons indicating Na build up. Irrigation with saline-sodic CBNG water contributes to increased Na concentrations through evapotranspiration and Na adsorption by soil (Burrow et al, 2002). Increased Na contents lower in the profile, may be due to downward movement (leaching) of CBNG irrigation water.…”

“…However, CBNG water brings with it a number of problems associated with poor quality irrigation water. Application of CBNG waters with high salinity (e.g., EC) can result in reduced water uptake and water stress to vegetation due to increased energy requirements of plants in obtaining soil water (Burrow et al, 2002). While tolerance to salinity varies among crop types, it is generally accepted that saline conditions have negative impacts on most crops.…”

Irrigation with coalbed natural gas (CBNG) co-produced water is a popular management option used by many gas companies operating in northwestern Powder River Basin (PRB), Wyoming. Depending upon local conditions and production rates, a CBNG well may be productive for 2 to 20 years, with an average lifespan of 7 years. At present there are over 20,000 CBNG wells permitted or drilled in the PRB region and it is estimated that another 50,000 to 100,000 new wells will be drilled in the future. The total CBNG water production in the PRB is expected to peak at about 47,000 ha-m in 2006 and the cumulative CBNG-water production during the period 2002-2017 is estimated to be 366,000 ha-m. CBNG water is dominated by sodium (Na + ) and bicarbonate (HCO 3 -) ions and the average discharge of a single CBNG well ranges from <1 to 100 liter per minute, with pH ranging from 6.8 to 9.0, electrical conductivities (EC) from 0.4 to 4 dS/m, Na adsorption ratio (SAR) from a low of 5 to an extreme high of 70 and total dissolved solids (TDS) concentrations from 270 to 2720 mg/L. Application of poorer quality CBNG water can have significant impacts on soil physical and chemical properties. Changes in soil chemistry due to land application of CBNG waters were investigated using lysimeters installed at depths of 15, 30, and 60 cm. Soil solutions collected during June to August 2004 from soil solution lysimeters were analyzed for EC and SAR. Soil solution chemistry data were compared with EC and SAR data from saturated paste extracts of CBNG irrigated soil samples collected at the same depth. Preliminary data indicate the build up of salts and Na in the upper horizons of irrigated fields. The EC values of lysimeter soil solution samples were greater than those of saturated paste. However, SAR of lysimeter soil solution and saturated paste extracts were comparable. The results of this study will be useful to understand potential changes in soil properties due to land application of CBNG waters and to develop possible mitigating criteria for reclaiming impacted PRB ecosystems.
