Total endoscopic and anal Irrigation Management approach to noncompliant neuropathic bladder and bowel in children: A long-term follow-up.
Urology Annals, 2017Co-Authors: Naif Alqarni, Hamdan Alhazmi, Ossamah Alsowayan, Tamer Eweda, Khalid Fouda NeelAbstract:Purpose To evaluate the long-term efficacy and durability of combined intradetrusor botulinum-A toxin (BTX-A), endoscopic treatment of vesicouerteral reflux and anal Irrigation for stool incontinence (SI) via a total endoscopic and anal Irrigation Management (TEAM®) approach in patients with myelomeningocele and neuropathic bladder and bowel who did not respond to conservative measures. Materials and Methods Fourteen myelomeningocele patients with at least 3 years follow-up were included in the study. All patients have urinary and SI not responded to conservative Management. All patients received a cystoscopic intradetrusor injection of 12 U/kg (maximum 300 U) BTX-A. There was vesicoureteral reflux in 22 ureters, and a Deflux® injection was completed during the same procedure. SI was managed using trans-anal Irrigation, either with a fleet enema or Peristeen® system regularly. Results After at least 3 years of follow-up, mean maximum bladder capacity increased significantly from 78 ± 36 ml to 200 ± 76 ml (P < 0.0001) and the maximum detrusor pressure decreased from 56 ± 12 cm H2O to 29 ± 7 cm H2O (P < 0.001). Twenty-one refluxing ureters (95%) showed complete resolution and one persisted. Ten patients (72%) achieved complete dryness between catheterizations. Four patients (28%) went for augmentation cystoplasty, due to progressive hydronephrosis and/or persistent urinary incontinence. Thirteen patients achieved complete stool continence. Conclusions Over long-term follow-up, major reconstruction surgery can be avoidable or delayable; the TEAM® approach is a minimally invasive, safe, simple, and effective way to achieve upper urinary tract protection and provide urinary and stool continence.

water requirement and growth indicators of forest tree species seedlings produced with automated Irrigation Management
PLOS ONE, 2020Co-Authors: Mateus Marques Bueno, Paulo Sergio Dos Santos Leles, Joao Felicio Goncalves Abreu, Jaqueline Jesus Santana Dos Santos, Daniel Fonseca De CarvalhoAbstract:The lack of information regarding the water requirement of tree species results in water waste in the seedlings production in nurseries. Water requirement, the growth plant factors and water efficiencies for height and diameter were determined for Schizolobium parahyba (Vell.) Blake, Cytharexylum myrianthum Cham. and Ceiba speciosa Ravenna seedlings, under automated Irrigation Management and greenhouse conditions, located at 22o45’53” S and 43o41’50” W. We used sewage sludge biosolids as substrate in the seedling phase (280 cm-3 tube), and sandy soil material in the initial pot growth phase (18 dm-3 pot). In the seedlings phase, four water replacement levels were applied to the substrate, by drip Irrigation, corresponding to average replacement ranging from 40 (V1) to 100% (V4) of the species water requirement. Seedlings developed properly and 80 days after emergence, S. parahyba, C. myrianthum and C. speciosa seedlings received, respectively, 2.40, 1.08 and 0.85 L per plant, for V4. After growth phase (230 DAE), the total water volumes were, respectively, 70.0, 50.3 and 52.7 L per plant. Under adequate water supply, there were rapid recovery and growth of the species, even for the seedlings which showed different height and diameter in the tube phase. The growth plant factors values found were below 0.5 for all species indicating low sensitivity to growth, both in height and in diameter, in response to water deficit. Water efficiency indicators point to distinct trends between the two phases, and C. speciosa has higher values of water efficiencies for height (80.7 and 17.0 cm L-1) and diameter (2.1 and 0.5 mm L-1) in both phases.

water requirement and yield of fig trees under different drip Irrigation Management
Engenharia Agricola, 2014Co-Authors: Irineu Pedro De Sousa Andrade, Daniel Fonseca De Carvalho, Wilk Sampaio De Almeida, Jonathas Batista Goncalves Silva, Leonardo Da SilvaAbstract:This work aimed to study the effect of drip Irrigation Management on growth and yield of the 'Roxo de Valinhos' fig tree (Ficus carica L.), at three years old, and to determine crop coefficients (Kc) and its water requirement (ETc) under Baixada Fluminense climate and soil conditions, state of Rio de Janeiro, Brazil. The study was carried out in the experimental area of SIPA (Sistema Integrado de Producao Agroecologica) in Seropedica, Rio de Janeiro State, from July 2011 to May 2012. The experimental area was divided in two blocks, named B1 (sandy clay loam texture) and B2 (loamy sand texture). In each block, Irrigation frequencies (IF) of two (T1) and four days (T2) were evaluated, as well as the Irrigation absence (T3). Irrigation Management and water consumption determination were performed through the soil water balance, using the TDR technique. Plant growth was not affected by IF, differing only in the number of produced internodes. For both soil textures, the mean Kc was 0.60, with a significant difference (p<0.05) only for IF. The estimated mean yield showed no significant differences between both textural classes, ranging from 6,612 kg ha-1 (T3) to 8,554 kg ha-1 (T1). This study indicates the importance of Irrigation frequency in the Irrigation Management of fig trees cultivated in soils with different physical characteristics.

Crop row detection through UAV surveys to optimize on-farm Irrigation Management
'MDPI AG', 2020Co-Authors: G. Ronchetti, A Facchi, A Mayer, B. Ortuani, G. SonaAbstract:Climate change and competition among water users are increasingly leading to a reduction of water availability for Irrigation; at the same time, traditionally non-irrigated crops require Irrigation to achieve high quality standards. In the context of precision agriculture, particular attention is given to the optimization of on-farm Irrigation Management, based on the knowledge of within-field variability of crop and soil properties, to increase crop yield quality and ensure an efficient water use. Unmanned Aerial Vehicle (UAV) imagery is used in precision agriculture to monitor crop variability, but in the case of row-crops, image post-processing is required to separate crop rows from soil background and weeds. This study focuses on the crop row detection and extraction from images acquired through a UAV during the cropping season of 2018. Thresholding algorithms, classification algorithms, and Bayesian segmentation are tested and compared on three different crop types, namely grapevine, pear, and tomato, for analyzing the suitability of these methods with respect to the characteristics of each crop. The obtained results are promising, with overall accuracy greater than 90% and producer's accuracy over 85% for the class "crop canopy". The methods' performances vary according to the crop types, input data, and parameters used. Some important outcomes can be pointed out from our study: NIR information does not give any particular added value, and RGB sensors should be preferred to identify crop rows; the presence of shadows in the inter-row distances may affect crop detection on vineyards. Finally, the best methodologies to be adopted for practical applications are discussed

a comprehensive modelling approach to assess water use efficiencies of different Irrigation Management options in rice Irrigation districts of northern italy
Water, 2019Co-Authors: A Mayer, M Rienzner, Sandra Cesari De Maria, M Romani, Alberto Lasagna, A FacchiAbstract:European rice production is concentrated in limited areas of a small number of countries. Italy is the largest European producer with over half of the total production grown on an area of 220,000 hectares, predominantly located in northern Italy. The traditional Irrigation Management (wet seeding and continuous flooding until few weeks before harvest—WFL) requires copious volumes of water. In order to propose effective ‘water-saving’ Irrigation alternatives, there is the need to collect site-specific observational data and, at the same time, to develop agro-hydrological models to upscale field/farm experimental data to a spatial scale of interest to support water Management decisions and policies. The semi-distributed modelling system developed in this work, composed of three sub-models (agricultural area, groundwater zone, and channel network), allows us to describe water fluxes dynamics in rice areas at the Irrigation district scale. Once calibrated for a 1000 ha district located in northern Italy using meteorological, hydrological and land-use data of a recent four-year period (2013–2016), the model was used to provide indications on the effects of different Irrigation Management options on district Irrigation requirements, groundwater levels and Irrigation/drainage network efficiency. Four scenarios considering a complete conversion of rice Irrigation Management over the district were implemented: WFL; DFL—dry seeding and delayed flooding; WDA—alternate wetting and drying; WFL-W—WFL followed by post-harvest winter flooding from 15 November to 15 January. Average results for the period 2013–2016 showed that DFL and WDA would lead to a reduction in summer Irrigation needs compared to WFL, but also to a postponement of the peak Irrigation month to June, already characterized by a strong water demand from other crops. Finally, summer Irrigation consumption for WFL-W would correspond to WFL, suggesting that the considered winter flooding period ended too early to influence summer crop water needs.

towards a smart automated surface Irrigation Management in rice growing areas in italy
Journal of Agricultural Engineering, 2017Co-Authors: Daniele Masseroni, C Gandolfi, Jasim Uddin, Reece Tyrrell, Iven Mareels, A FacchiAbstract:Italy is the leading rice producer in Europe, accounting for more than half of the total high-quality production of this crop. Rice is traditionally grown in fields that remain flooded starting with crop establishment until close to harvest, and this traditional Irrigation technique ( i.e ., continuous submergence) is recognised as an important water resource sink (almost 40% of the Irrigation water available worldwide is used for paddy areas). Meanwhile, the water Management in rice areas requires a high level of labour because it is based on maintaining a predetermined water height in paddy fields and because the regulation of input and output flow is typically operated manually by the farmer. This study reveals the hardware and software characteristics of an automated and remote controlled technology tested for the first time in a rice farm near Pavia (Italy), during the 2016 growing season, aiming at a more efficient and less burdensome Irrigation Management system for rice fields. A water level sensor in the field provides the data required to govern the inflow regulation gate in real-time, according to the precise time to cut off the flow rate. Using a dedicated web page, the farmer can control flows, volumes and water levels in the fields by operating directly on the gate if necessary or setting the Irrigation program according to his agronomic practices.

Matric potential-based Irrigation Management of field-grown strawberry: Effects on yield and water use efficiency
Agricultural Water Management, 2015Co-Authors: Guillaume Létourneau, Jean Caron, L. Anderson, Julien CormierAbstract:Abstract Effective and adapted criteria for Irrigation scheduling are required to improve yield and water use efficiency (WUE) and reduce the environmental impacts associated with water and nutrients losses by runoff and leaching. In this study, field-scale experiments were conducted at four commercial strawberry production sites with contrasting soil and climatic conditions. Within each site, the influence of different soil matric potential-based Irrigation thresholds (IT) on yield and WUE was evaluated. Matric potential-based Irrigation Management was also compared with common Irrigation practices used by producers in each site's respective areas. At Site 1 (silty clay loam; humid continental (Dfb) climate), an IT of −15 kPa improved yields by 6.2% without any additional use of water relative to common Irrigation practices. At Site 2, with similar soil and climatic conditions, the Irrigation treatments did not affect yield and the matric potential-based Management decreased WUE relative to common practices. However, the results suggested that maintaining the soil matric potential lower than −9 kPa could induce stressing conditions for the plants. At Site 3 (sandy loam; Mediterranean (Cs) climate), the best yield and WUE were obtained with an IT of −8 kPa and suggested that WUE could be further improved by implementing high-frequency Irrigation. At Site 4 (clay loam; Mediterranean (Cs) climate), results suggested that an IT between −10 and −15 kPa could optimize yield and WUE, and matric potential-based Irrigation considerably reduced leaching under the root zone relative to common practices. Considering the results from all sites, an IT of −10 kPa appears to be adequate as a starting point for further optimizing Irrigation under most field conditions.

application of dssat ceres wheat model to simulate winter wheat response to Irrigation Management in the texas high plains
Agricultural Water Management, 2016Co-Authors: Ahmed Attia, Nithya Rajan, Qingwu Xue, Shyam Nair, Amir M H Ibrahim, Dirk B HaysAbstract:Abstract Winter wheat (Triticum aestivum L.) is a major crop in the semi-arid Texas High Plains. Irrigated winter wheat production in this region mainly depends on water from the Ogallala Aquifer. However declining water levels in this aquifer is a major concern for producers and policy makers. A modeling study was conducted using the DSSAT-CERES-Wheat model for accurate prediction of winter wheat grain and biomass yields and water use efficiency (WUE) responses to Irrigation Management in the Texas High Plains. Model calibration was performed using field observations of winter wheat response to nine Irrigation treatments ranging from dryland to full Irrigation. Close match of simulated crop phenology, grain and biomass yields, and evapotranspiration (ET) with observed data indicated accurate prediction of these parameters by the model. Results of simulations using historical weather data for 32 years (1980–2012) showed that a single Irrigation of 100 mm at jointing or booting had 35% higher grain yield than dryland while 140 mm at anthesis or grain filling produced 68% higher grain yield compared to dryland. Simulation of biomass yield showed significant advantage of irrigating 100 mm at jointing or booting stage compared to 140 mm at anthesis or grain filling. Irrigation of 100 mm at jointing and 140 mm at anthesis (240 mm in total) was found to produce similar grain and biomass yields as full Irrigation (400 mm). Deficit Irrigation at grain filling significantly increased WUE compared to full Irrigation. Advantage of deficit Irrigation was more pronounced at seasons with below average precipitation. These results show the importance of Irrigation timing in winter wheat production under water-limited conditions in the Texas High Plains.
