Changes in selected soil physical properties caused by sodicity of soil and irrigation water

We conducted a greenhouse study on large, semi-disturbed soil cores excavated from the vicinity of Verdigris Lake in southern Alberta to assess the suitability of different saline-sodic waters for irrigation. Soil salinization and sodication, surface soil physical properties, and yield of five soft white spring wheat crops (Triticum aestivum L. var. AC Reed) were examined under alternate applications of simulated rain with saline-sodic irrigation waters ranging from "safe" to "potentially hazardous" for irrigation. Increased salinity and sodicity of irrigation waters alternated with simulated rain resulted in increased salinity and sodicity in the upper 0.60 to 0.90 m of the soil. Salt accumulation in the root zone decreased as the leaching fraction increased. Aggregate stability and infiltration properties of the soil were generally adversely affected by the more saline and sodic irrigation waters. Infiltration properties were significantly greater with irrigation water (IW) than with distilled water (DW). The soil infiltration rate at 2 h, with DW as the infiltrating water, was the most sensitive soil physical property for assessment of irrigation water suitability. The infiltration test after five crop cycles gave a better indication of the effects of excess sodicity of irrigation water on soil structural stability than the aggregate stability test. The cumulative effects of long-term supplemental irrigation with saline-sodic waters on soil chemical and physical properties need to be considered when assessing irrigation water suitability. Irrigation waters with electrical conductivity (EC) less than or equal to 1 dS m-1 and a sodium adsorption ratio (SAR) less than or equal to 5 did not result in deterioration of soil physical properties and were considered "safe" for supplemental irrigation of the Masinasin soil. Alternate applications of irrigation and distilled water should be used to evaluate soil infiltration rates and the structural stability of soils to which saline-sodic waters are to be applied.

General Physical

Abstract The mechanical composition of soils in the middle reaches of the Zarafshan River (Jambay, Samarkand, Payarik, Ishtikhon, Kattakurgan and Narpay districts) and the processes of formation of soil layers under the influence of irrigation water of general physical properties were scientifically analyzed. In this case, the inflow of the Zarafshan River played an important role in the formation of light agroirrigation strata. An increase in nutrients and humus with an increase in the amount of physical sludge over a long period of time (35–40 years) is positively assessed for thickening of the soil layer, but leads to an increase in bulk mass of 0.15–0.3 g / cm3 and soil compaction.

The current study investigated the effect of water quality (the salinity of the irrigation water) and Tillage system on some soil physical properties. The experiment was carried out using RCBD with three replicates. wheat was irrigated by three water sources, a river ,dranege and well waters with electrical conductivities 1.3, 3.5 and 6.9 ds.m-1 respectively and three tillage systems were zero tillage (ZT), conventional tillage (CT) and deep tillage (DT). After harvest, some soil physical properties were evaluated including: bulk density, porosity, penetration resistance, hydraulic conductivity and mean weight diameter. The result showed that the bulk density values were 1.40, 1.44 and 1.47 mg.m-3 for river, derange and well water. while the porosity values were 47.3%, 45.8% and 43.8%. for river, derange and well water. while the hydraulic conductivity were 5.13, 4.26 and 4.36 cm.h-1for river , derange and well water. also the result showed that the bulk density values were 1.48, 1.44 and 1.38 mg.m-3 for ZT, CT and DT respectively. while the porosity values were 44.3, 45.7 and 47.8% for ZT, CT and DT respectively. But for the interactions for electrical conductivity with tillage The result showed that the bulk density values were 1.50 mg.m-3 for well water with ZT but decrees value it become 1.34 mg.m-3 for river water with DT. The best type of tillage was conventional tillage as it has the ability to improve properties of soil as well as it helps to reduce.
