Significance to human health of carbamazepine detected in fruits and vegetables irrigated with recycled water
The relevance and significance of the findings of chemicals of emerging concern at nanogram concentrations in recycled water is critically important for the consumers of these crops. The relevance and significance of these chemicals at these concentrations is placed in perspective in terms of the number of years of consumption necessary to accrue one acceptable daily intake every day, over a ...

Arsenic concentrations in irrigation water, soil and selected vegetables in Bangladesh
The effect of Arsenic (As) concentration in irrigation water on As accumulation in six selected vegetables grown during the dry season (December-May) in Bangladesh has been assessed. Three field sites were selected for the assessment, which included two As affected areas (Chandpur and Narayanganj) and one unaffected area (Bogra). The As concentrations in edible parts of the selected vegetables ...

Precision application of water for peri-urban horticulture
Vegetables are grown in the peri-urban zone throughout Australia on various soil types and in various climates. In order to grow vegetables throughout the year, irrigation is generally needed to supplement natural precipitation. Peri-urban horticulture in the Sydney region supplies fresh vegetables, cut flowers, turf and other farm produce. Competition for water and environmental impacts (e.g. ...

Influence of rainfall interception by endemic plants versus short cycle crops on water infiltration in high altitude ecosystems of Ecuador
Owing to their high water retention, the volcanic ash-soils of the Northern Andean highlands (páramos) can be considered as natural ‘water storage tanks’ for drinking water and for irrigation. Vegetation plays an important role in transferring rain to the soil and in controlling the soil water content. To assess this role, we quantified the stemflow process under rainfall simulations for ...

Irrigation and Nitrogen Best Management Practices Under Drip Irrigated Vegetable Production
Abstract Plastic mulch and drip irrigation are commonly used in high intensity vegetable production regions such as Florida. Drip irrigation can be much more efficient than sprinkler irrigation since only the root zone of the cropped area is irrigated. However, improper irrigation management can lead to wasted water and leaching of soluble chemicals such as nitrate. In this project, several ...

Modeling the die-off of
E. coli andAscaris in wastewater-irrigated vegetables: implications for microbial health risk reduction associated with irrigation cessationThis study assessed the die-off of Escherichia coli (E. coli) and Ascaris suum on lettuce (Great Lakes 118) and cabbage (Brassica oleracea var capitata) in wastewater-irrigated fields using comparative mathematical die-off models. The study revealed that none of the survival curves of E. coli and A. suum was best fitted with the log-linear model, indicating that the classical first-order ...

A probabilistic QMRA of
Salmonella in direct agricultural reuse of treated municipal wastewaterDeveloping reliable quantitative microbial risk assessment (QMRA) procedures aids in setting recommendations on reuse applications of treated wastewater. In this study, a probabilistic QMRA to determine the risk of Salmonella infections resulting from the consumption of edible crops irrigated with treated wastewater was conducted. Quantitative polymerase chain reaction (qPCR) was used to ...

Special features of drip-sprinkler irrigation technology
Irrigation techniques and technology based on principle of regular accumulation of moisture in active layer (surface irrigation, regular sprinkler irrigation) are most common in science and in practice. More progressive is principle of non-stop water supply of plants and soil in conformity to their water consumption. Drip irrigation and impulse sprinkling are based on this principle. The main ...

Tree, Crop & Plant Stress – A Primer on Abiotic and Biotic Stressors
The natural conditions in which plants and trees grow are neither uniform nor controlled. Many changes or fluctuations, even if they are temporary, can have a negative impact on and stress plants. The factors which can lead to stress can be one of two types: abiotic or biotic. Stress can have serious repercussions on various phases of a plant’s growth and, ultimately, crop productivity. ...

Crops flourish with Scalewatcher
Water is an essential component of horticulture and agriculture whether it is used for irrigating field-scale vegetables, nursery stock, flowers or fruit. Where water contains high degrees of calcium, magnesium and sodium, it can cause nutrient deficiency in plants and crops resulting in stunted growth and poor yields. Calcium also blocks irrigation systems and boilers in heated greenhouses, ...
