    ABSTRACT: While modernization of olive cultivation has recently lead to vast expansion of fully irrigated orchards, characterization of olive tree nutritional status remains based on knowledge gleamed from rain-fed orchards. In the present study, the effect of irrigation level on olive tree nutritional status was investigated in Israel over 4 years on two cultivars and in two locations characterized by differences in soil, tree age, management history, fertilizer application and irrigation water quality. Diagnostic leaves, sampled in July, were evaluated as indicators of nutritional status. Leaf nitrogen concentration was not affected by irrigation level. Leaf phosphorous and potassium concentrations increased with increasing irrigation level. Leaf calcium, manganese and iron tended to decrease with irrigation, while magnesium, sodium and zinc concentrations were not generally affected by irrigation level. Leaf boron and chloride concentrations increased with increasing irrigation when their concentration in irrigation water was relatively high. Leaf nutrient concentration was influenced by cultivar. The results presented in this study emphasize a strong link between irrigation level and the nutritional status of olives for some nutrients and no association for others. These findings should aid in developing distinct fertilization recommendations for fully irrigated olives, different from those developed and used for rain-fed or supplemental-irrigated orchards.

    ABSTRACT: This paper describes a method of irrigation called measured irrigation (MI). MI is a gravity-feed irrigation system that directly controls the volume of water emitted from each emitter nozzle in each sector during the irrigation event without the need to control the flow rate or the duration of the irrigation event. Three implementations of MI are described: unpowered single-sector MI, solar-powered single-sector MI and solar-powered multi-sector MI. For solar-powered MI, the irrigation frequency is proportional to the evaporation rate minus the precipitation rate. MI does not require access to electricity grid power or to an urban water supply. Trials compare the accuracy and uniformity of MI with pressure-compensating drip irrigation products.

    ABSTRACT: The classical head–discharge relation for rectangular sharp-crested weirs is applicable only to free flow conditions, not valid at low head when flow becomes clinging. Based on experimental data for eight sharp-crested rectangular weirs of different sizes, a new method for calculating discharge at the low head bistable and clinging flow regime was proposed in this study. In the bistable zone, the head–discharge relationship can be covered partly by the classical weir–discharge equations of free flow. The discharge coefficient is quite similar to Rehbock’s equation for free flow with a surface tension term. In the clinging flow regime, the head had to be transformed into an equivalent head obtained by regression. All the regression parameters were about the same for the weirs of different sizes. In the clinging zone, discharge was also directly proportional to weir width, while unit width discharge was directly proportional to the square of head, independent of weir height. The errors of model-predicted discharge were less than 10 % for more than 90 % of the data points. Therefore, the proposed method for discharge of clinging flow is applicable to rectangular sharp-crested weirs at very low head, while the classical formulas often fail under these flow conditions.

    ABSTRACT: Variable-rate irrigation (VRI) systems have the potential to conserve water by spatially allocating limited water resources. However, when compared to traditional irrigation systems, VRI systems require a higher level of management. In this 3-year study, we evaluated spatial irrigation management of a peanut crop grown under a VRI system using an expert system (Irrigator Pro). The irrigation management treatments evaluated were: (1) using Irrigator Pro (IP) to manage irrigation uniformly in plots with varying soils; (2) using Irrigator Pro to manage irrigation in plots based on the individual soils (IPS); (3) a treatment based on maintaining soil water potential (SWP) above −30 kPa (approximately 50 % depletion of available water) in the surface 30 cm of each soil within a plot; and (4) a non-irrigated treatment. Over the 3-year study, all irrigated treatments had significantly higher yields (4,230, 4,130, and 4,394 kg ha−1 for the IP, IPS, and SWP treatments, respectively) than the non-irrigated treatment (3,285 kg ha−1), yet the yields of the three irrigation treatments were not significantly different. Averaged over the 3-year experiment, the three treatments did not differ significantly in water usage. In the 2007 and 2009 growing seasons with below normal rainfall, the IP and IPS treatments required significantly greater total water than the SWP treatment. Overall, water use efficiency was significantly higher for the non-irrigated and SWP treatments (9.4 and 8.9 kg ha−1 per mm, respectively). The lower water use efficiency for the IP and IPS irrigation treatments (7.8 kg ha−1 per mm) was attributed to greater water applications mainly due to earlier growing season initiation of irrigation applications. However, the IP and IPS treatments maintained soil water potentials at the 30- and 60-cm depths at higher levels throughout most of the season. The two Irrigator Pro expert system treatments functioned as well as the SWP-based treatment. The Irrigator Pro expert system can be effectively used for site-specific management where management zone soils do not greatly differ. Further refinement of the expert system may be needed to improve its application in spatial irrigation applications.

    ABSTRACT: Emitter clogging has become one of the main restrictions in the development of drip irrigation with reclaimed water. Numerous studies have found that emitter clogging is closely related to the formation and growth of biofilms attached within the emitter wall, raising the question of how to effectively control the formation of biofilms, which is the key to solving emitter clogging. Lateral flushing could promote the rapid shedding of biofilms and wash the irrigation system by increasing the hydraulic shear force within the laterals; this would reduce the frequent shedding of biofilms from the lateral walls into the emitter during the irrigation operation and the clogging of the emitter. Therefore, we conducted an in situ drip irrigation experiment with reclaimed water in a sewage treatment plant under three conditions of lateral flushing frequency (triweekly, biweekly, and weekly), and the dynamic changes in emitter clogging and biofilm components were studied. We found that lateral flushing can effectively slow down emitter clogging in a reclaimed water drip irrigation system. The values for the discharge ratio variation and coefficient of uniformity were the highest, and those for solid particles and phospholipid fatty acids were the lowest for the biweekly lateral flushing frequency. However, lateral flushing failed to completely solve the emitter clogging problem, and some additional measures must be combined with this process to control emitter clogging problems.

    ABSTRACT: Intercropping, drip irrigation, and the use of plastic mulch are important management practices, which can, when utilized simultaneously, increase crop production and save irrigation water. Investigating soil water dynamics in the root zone of the intercropping field under such conditions is essential in order to understand the combined effects of these practices and to promote their wider use. However, not much work has been done to investigate soil water dynamics in the root zone of drip-irrigated, strip intercropping fields under plastic mulch. Three field experiments with different irrigation treatments (high T1, moderate T2, and low T3) were conducted to evaluate soil water contents (SWC) at different locations, for different irrigation treatments, and with respect to dripper lines and plants (corn and tomatoes). Experimental data were then used to calibrate the HYDRUS (2D/3D) model. Comparison between experimental data and model simulations showed that HYDRUS (2D/3D) described different irrigation events and SWC in the root zone well, with average relative errors of 10.8, 9.5, and 11.6 % for irrigation treatments T1, T2, and T3, respectively, and with corresponding root mean square errors of 0.043, 0.035, and 0.040 cm3 cm−3, respectively. The results showed that the SWC in the shallow root zone (0-40 cm) was lower under non-mulched locations than under mulched locations, irrespective of the irrigation treatment, while no significant differences in the SWC were observed in the deeper root zone (40-100 cm). The SWC in the shallow root zone was significantly higher for the high irrigation treatment (T1) than for the low irrigation treatment, while, again, no differences were observed in the deeper root zone. Simulations of two-dimensional SWC distributions revealed that the low irrigation treatment (T3) produced serious severe water stress (with SWCs near the wilting point) in the 30-40 cm part of the root zone, and that using separate drip emitter lines for each crop is well suited for producing the optimal soil water distribution pattern in the root zone of the intercropping field. The results of this study can be very useful in designing an optimal irrigation plan for intercropped fields.

    ABSTRACT: Clogging of subsurface drip irrigation (SDI) systems by root penetration into the emitters results in inappropriate water supply, increased replacement rates of SDI systems and increased costs. We found that impregnation of SDI drippers with copper oxide particles inhibits root penetration very significantly. The inhibition of root penetration varied from 24 to 76 % of the control (60-80 % intrusion) depending on the copper oxide concentration of the drippers. The root penetration inhibition was demonstrated at two water flow rates, of 1 and 3.5 l/h, and with new and used drippers after 1750 irrigation hours. Inhibition of root penetration occurred also if sewage water was used. The inhibition of root penetration into drippers was demonstrated with lettuce and tomato plants and reached similar efficacy as compared to the widely used herbicide Stomp® root penetration inhibition treatment. The amount of copper that leached into the water was below detection limit (less than 0.006 ppm). No loss of copper oxide particles was detected in drippers through which 3350 l of water was passed (an amount of water that typically passes in SDI systems during 3-4 years of use), as determined by scanning electronic microscope and X-ray photoelectron spectrum analysis.

    ABSTRACT: Excessive precipitation since 1993 has produced extensive flooding in the Devils Lake basin in northeastern North Dakota, USA. Irrigation of agricultural crops has been proposed as a flood mitigation tool. Ten test fields were equipped with center pivot irrigation systems to compare test field evapotranspiration (ET) with ET for crops in the predominantly nonirrigated basin. An irrigation scheduling analysis indicated 2006 was a favorable year to estimate the maximum ET gains achievable via irrigation. An ET map for 2006 using the Surface Energy Balance Algorithm for Land (SEBAL) for 54 % of the basin, and land use and soil survey data, was used to compare ET estimates at the test fields with ET estimates across the study area. May–September ET was estimated by SEBAL as 394 mm for wheat and 435 mm for corn across the study area, while corn ET at irrigated test sites was 452 mm. Because the 17-mm ET advantage by irrigating corn was substantially smaller than the 41-mm ET advantage for corn versus wheat, we conclude widespread irrigation development to mitigate flooding is not justified. Coarse-textured soils exhibited some seasonal ET deficits, but their small areal extents and parcel sizes offer virtually no opportunity for flood mitigation.

    ABSTRACT: Appropriate geometries and depths of containers are essential in obtaining suitable available water and temperature in the root zone of containerized grown plants. The objectives of the present study were to examine the effect of the geometry of a growth container with a given volume and irrigation frequency, on water content and temperature of the growing medium and on water uptake, yield and quality of lettuce (Lactuca sativa L.) as a model plant. Two experiments, in the spring and fall, were conducted in a greenhouse. Plants were grown in a volume of 4 L per plant of medium mixture of 0–8 mm tuff (90 %) with compost (10 %). Treatments included three container heights (10, 20 and 30 cm) and two irrigation frequencies (4–6 and 12–18 applications per day and 2 night applications for both). Lettuce head fresh weight was lower in the spring than in the fall and was not significantly affected by container geometry or irrigation frequency. However, the number of tip burn damaged leaves per plant increased significantly with container height, especially for the high irrigation frequency treatments. Container geometry had an effect on the water and temperature regimes. Water content values in tall and narrow containers were lower than those in short and wide containers that had an equal volume of growth medium per unit length. Higher medium temperatures and daily fluctuations were observed in the tall containers. The calculated evapotranspiration rate was higher in the tall containers, and a stronger effect on evapotranspiration was obtained with high irrigation frequency.

    ABSTRACT: Drip irrigation systems are prone to changes in flow rate (FR) and increasing coefficients of variation (CV) when fed with treated wastewater, due to fouling inside the drippers. A model system was designed to measure the FR and fouling accumulation in laterals and drippers under different treatment conditions. A novel approach was taken to compare the different maintenance treatments. A comparison of chlorination and acidification strategies showed that daily chlorination and periodic acidification may prolong proper functioning of the drippers by maintaining a normal FR [(up to +/- 7 %) of nominal FR] and CV (< 7 %) index in correlation with low fouling accumulation in the pipeline (< 0.01 mg deposit/cm (pipe) (2) ). Current recommendations for the frequency of conventional treatments were found to be insufficient. Chemical analyses of the fouling inside the dripper and accumulated on the pipe wall showed that biofilm can survive inside the dripper under harsh environmental conditions, even when the pipeline stays clean. These results shed light on biofilm growth and survival mechanisms inside the dripper and may pave the way to developing new treatments or improving dripper design.

    ABSTRACT: A variety of techniques have been proposed in the literature for sprinkler drop characterization. An optical particle tracking velocimetry (PTV) technique is proposed in this paper to determine drop velocity, diameter and angle. The technique has been applied to the drops emitted by an isolated impact sprinkler equipped with two nozzles (diameters 3.20 and 4.37 mm) operating at a pressure of 175 kPa. PTV has been previously used to determine the velocity vector of different types of particles. In this research, PTV was used to photograph sprinkler drops over a region illuminated with laser light. Photographs were taken at four horizontal distances from the sprinkler, which was located at an elevation of 1.65 m over the soil surface. Drop angle and velocity were derived from the displacement of the drop centroid in two images separated by a short time step. Centrality and dispersion parameters were obtained for each drop variable and observation point. Results derive from the analysis of 2,360 images. Only 37.5 % of them (884 images) contained drops which could be processed by the PTV algorithm, resulting in a total of 3,782 drops. A filtering algorithm just validated 1,893 valid drops, which were successfully analyzed. The proposed technique uses expensive equipment requiring continued protection against irrigation water. This methodology has proven valuable to characterize irrigation water drops. Despite its robust measurement procedure, further comparison with other techniques seems necessary before this optical technique can be recommended for practical use in sprinkler drop characterization.
