This study focused on assessing surface water quality in the northwest part of Egyptian Nile Delta (El-Menoufia Governorate) and evaluated suitability for irrigation purposes using Irrigation Water Quality Index (IWQI), Permeability (PI), Wilcox, United State Salinity (USSL) diagram, Piper trilinear diagrams categories, taking into consideration various parameters. The results showed that, based IWQI, most samples (61.8%) investigated area fell under no restriction (NR) category. Furthermore, Wilcox diagram demonstrated that (93.6%) are categorized as doubtful water; this shows those have a higher sodium content material. According to USSL (70.9%) high salinity (C) moderate (S) (C3S2) class. PI index, 8.2% tested class II (suitable irrigation) 91.8% III (unsuitable irrigation). Based trilinear, type is Na-Cl-HCO3. these results, require more regulations, causes plants’ augmentation sensitivity if used irrigation, (EC) absorption ratio (SAR) magnitude, which might negative outcomes soil plant health extensive obstacles, improper irrigation.

Abstract The Fens is a region that contributes 11% of the agri-food economy from just 4% agricultural land covering England (UK). This vulnerable to soil salinisation sea-level rise with estimated 100-year flood events projected be observed up every 2 years by 2100. Seawater intrusion and upwelling saline groundwater can provide an additional pathway; however, area’s has not been assessed risk unknown. study used data British Geological Survey’s stratigraphic core archive produce first map loosely consolidated Holocene deposits in South Holland–Holbeach Marsh region.

The automatic detection of Center Pivot Irrigation Systems (CPIS) is fundamental for establishing public policies, especially in countries with a growth perspective this technology, like Brazil. Previous studies to detect CPIS using deep learning used single-date optical images, containing limitations due seasonal changes and cloud cover. Therefore, research aimed Sentinel-2 multitemporal images (containing six dates) instance segmentation, considering variations different proportions cloudy generalizing the models diverse situations. We novel augmentation strategy, which, each iteration, were randomly selected from time series (from total 11 random order. evaluated Mask-RCNN model ResNext-101 backbone COCO metrics on testing sets ratios cloudless ( $< 20\%$ ) notation="LaTeX">$>75\%$ ), zero (6:0) up one image five (1:5). found that provided best [80% average precision (AP), 93% AP 0.5 intersection over union threshold (AP50)]. However, results similar (74% AP, 88% AP50) even extreme scenarios abundant presence (1:5 ratio).

The evaluation of the spatial and temporal variability soil properties can be valuable to improve crop productivity health. A study was carried out in southern Portugal, three farm fields with irrigated annual crops (layers 0–20 cm 20–40 cm), over years. Factor Analysis (FA) Discriminant (DA) were used analyze data. With FA, observed variables grouped into a smaller number latent related attributes. classify identify most dominant attributes indicators for time space parameters. FA performed surface layer included factors texture, water nutrient retention capacity, chemical composition, fertility. In sub-surface layer, factor structure similar, four availability, influential discrimination (sampling dates) both layers those electric conductivity as preponderant indicator. As differentiation (fields), availability. important discriminant fine sand proportion available potassium, respectively, layers. results obtained showed potential multidimensional integrated assessment patterns variation functions from agricultural practices or degradation processes.
