    ABSTRACT: Irrigation with treated wastewater (TWW) is gaining importance due to declining water availability in dry regions. TWW irrigation has various potential adverse effects on soil quality such as hydrophobic effects on soil surfaces, reducing initial sorptivity and promoting the formation of preferential flow paths. In May and June 2010, in situ infiltration measurements using mini disk tension infiltrometer were deployed in five different orchard plots in Israel to assess the impact of different irrigation water qualities on the soil water repellency index R. In most plantations, long-term test sites were accessed to compare adjacent plots irrigated with fresh water (FW) or TWW. Topsoil samples were analyzed for selected physical and chemical characteristics. The mean R values increased at all TWW sites, from +15 up to +55 % compared with FW sites. The water drop penetration time (WDPT) increased up to 30 fold at three of five TWW sites compared with FW sites. Subsequent U tests and multilevel analysis indicated an impact of the type of irrigation water on R and WDPT. Moreover, soil electrical conductivity and exchangeable sodium percentage were consistently higher at all TWW sites. These results show that irrigation water quality clearly influences physical and chemical properties of the soil.

    ABSTRACT: A major constraint on the use of treated wastewater (TWW) in microirrigation systems is the potential for fouling. This research aimed to assess the occurrence of fouling in drip irrigation systems applying TWW and determine the quantity and chemical characteristics of the fouling. A field survey was performed to determine the incidence of chemical and biological fouling in irrigation systems and its influence on system performance. Dripper flow rate, total and volatile solids, chemical composition, and diffuse reflection infrared Fourier transform (DRIFT) spectra of the fouling material were determined. Fouling was found in all of the drip irrigation systems sampled under a variety of conditions. The fouling contained a high percentage of organic matter (OM), except for two instances where the material was mainly inorganic. Identification of the functional groups using DRIFT showed that the OM found is essentially of aliphatic and amide origin. Comparing the spectra obtained from the various sites revealed considerable similarity in the material properties. This suggests a common mechanism in all irrigation systems tested, but a different accumulation rate. A high correlation was found between total phosphorus concentration, the sum of Ca and Mg concentrations and the TWW pH, and the content of total and organic carbon in the fouling. In addition, the correlation between equipment age and the amount of accumulated total solids was high for systems containing high quantities of fouling. The concentration of volatile solids was highly correlated with the age of the irrigation system.

    ABSTRACT: Lysimetric experiments were conducted to determine the contribution made by groundwater to the overall water requirements of safflower (Carthamus tinctorius L.). The plants were grown in 24 columns, each having a diameter of 0.40 m and packed with silty clay soil. The four replicate randomized complete block factorial experiments were carried out using different treatment combinations. Six treatments were applied during each experiment by maintaining groundwater, with an EC of 1 dS m-1, at three different water table levels (0.6, 0.8 and 1.10 m) with and without supplementary irrigation. The uptake of groundwater as a part of crop evapotranspiration was measured by taking daily readings of the water levels found in Mariotte tubes. The supplementary irrigation requirement for each treatment was applied by adding water (EC of 1 dS m-1). The average percentage contribution from groundwater for the treatments (with and without supplementary irrigation under water table levels of 0.6, 0.8 and 1.10 m) were found to be 65, 59, 38% and 72, 70, 47% of the average annual safflower water requirement (6,466 m3 ha-1). The increase in groundwater depths under supplementary irrigation treatments from 0.6 to 0.80 and 1.10 m caused seed and oil yield reductions of (7, 23.10%) and (48.23, 65.40%), respectively

    ABSTRACT: Accurate prediction of crop coefficient (K c) is necessary for proper irrigation management. We explored CropSyst for determining irrigation requirements of apple trees and for accuracy of K c prediction. Values of K c were compared to those obtained, over 2002–2010, from lysimeter-grown trees. Over these years, trees had different ratios of height (H) to width (W). CropSyst predicted irrigation requirements using tree light interception and water uptake sub-model components. Parameters of the model were adjusted using data obtained from the lysimeter in 2010. Tree light interception sub-model was verified by 2007 data. After parameterization, good agreement was found between simulated and measured K c over different seasons. The porosity coefficient of the canopy was related to changes in tree’s H/W ratio and leaf overlapping. Accordingly, different porosity values could be estimated for each year. When yearly changes in canopy porosity was considered, CropSyst improved K c prediction and generated relevant information for managing irrigation under changing canopy shape for apple trees.

    ABSTRACT: Local losses, which affect the uniformity of water application, are often ignored in the design of irrigation systems. Some accessories have no simple, efficient equations to estimate these losses. The main objective of this work was to develop an equation to estimate the local head loss in lateral passage connectors. Fifteen connector/pipe combinations were tested. The connectors were characterized by their internal diameters and dimensions. The local head loss was determined by subtracting the head loss on the connector and pipe from the head loss on the pipe. The parameters affecting the local head loss were defined as dimensionless terms using Buckingham’s theorem. A mathematical model was developed that presented a determination coefficient of 93.31 %. Elements such as the inner diameter of the connector, pipe length, connector, water flow velocity, Reynolds number and Froude number influenced the local head loss in the connectors. The model was compared with the observed data and presented excellent performance. It can be used to calculate the local head loss in lateral passage connectors.

    ABSTRACT: This study investigated the impact of using treated wastewater and deficit irrigation on yield, water productivity, dry matter and soil moisture availability. The experiment included six treatments of deficit irrigation with treated wastewater during the 2010 and 2011 seasons and two deficit irrigation treatments combined with 3 organic amendment levels during the 2012 season. The experimental and SALTMED modelling results indicated that regulated deficit irrigation when applied during vegetative growth stage could stimulate root development, increase water and nutrient uptake and subsequently increase the yield. The organic amendment has slightly improved yield under full irrigation but had relatively small effect under stress conditions. The SALTMED model results supported and matched the experimental results and showed similar differences among the different treatments. The model proved its ability to predict soil moisture availability, yield, water productivity and total dry matter for three growing seasons under several deficit irrigation strategies using treated wastewater. The high values of the coefficient of determination R 2 reflected a very good agreement between the model and observed values. The SALTMED model results generally confirm the model’s ability to predict sweet corn growth and productivity under deficit irrigation strategies in the semi-arid region.
