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 ...

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 ...

A probabilistic assessment of the contribution of wastewater-irrigated lettuce to
Escherichia coli O157:H7 infection risk and disease burden in Kumasi, GhanaWastewater use for vegetable production is widespread across the cities of many developing countries. Studies on the microbial health risks associated with the practice have largely depended on faecal indicator organisms with potential underestimation or overestimation of the microbial health risks and disease burdens. This study assessed the Escherichia coli O157:H7 infection risk and ...

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 ...

Modelling water requirements of greenhouse spinach for irrigation management purposes
Estimating water requirements of plants cultivated in greenhouse environments is crucial, both for the design of greenhouse irrigation systems and the improvement of irrigation scheduling. Spinach is one of the main vegetables sold as ‘ready-to-eat’ bagged produce; it is very sensitive to water stress and thus requires accurate irrigation. In this work, a water balance model simulating the ...

Features of impulse sprinkling technology
The principle of non-stop water supply to plants and soil in accordance with their water intake is progressive. Drip irrigation and impulse sprinkling correspond to this principle. Drip irrigation provides optimal water and nutrient regimes directly to the root system of plants. However, this irrigation is not effective enough under conditions of high temperature (over 25–35 °C) as growth ...

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. ...

Irrigation and Nutrition
Mike, our Agronomist, was recently asked a few questions about irrigation and nutrition for a magazine. What quality parameters can be influenced (fruit size, flavour, firmness, shelf life, etc.)? All crop quality parameters can be enhanced through correct use of nutrition. Having the ideal strength and balance of nutrients at all stages of the crop cycle will help to ensure the best product ...

Spatial mapping of complex turfgrass sites: site-specific management units and protocols
Site-specific management units (SSMUs), similar in soil, plant, and irrigation requirements, are foundational to efficient management in precision agriculture. This concept is applied to management of complex turfgrass sites to improve irrigation practices. An experimental mobile unit mapped two golf fairways' turfgrass (Paspalum vaginatum SW.; ‘Salam’) in Naples, FL in summer 2006 on a 2.5 m ...

Can drip irrigation keep the Prairie Profitable?
The use of flood and center pivot irrigation of crops via the waters of the Ogallala Aquifer is as hot a discussion topic as the current drought. To many who mine the aquifer to make a living, trying to keep a profitable way of life sustainable in a time when the broader public is seeking more conservation of resources yet wanting inexpensive, plentiful and safe food is problematic. Perhaps it's ...

Monitoring of Nitrate Leaching in Sandy Soils: Comparison of Three Methods
Abstract Proper N fertilizer and irrigation management can reduce nitrate leaching while maintaining crop yield, which is critical to enhance the sustainability of vegetable production on soils with poor water and nutrient-holding capacities. This study evaluated different methods to measure nitrate leaching in mulched drip-irrigated zucchini, pepper, and tomato production systems. Fertigation ...

A strategy for sustainable livestock husbandry wastewater treatment in China
A strategy for sustainable treatment of the livestock husbandry wastewater is proposed, which is to recycle anaerobic treatment effluent as irrigation water. The existing treatment system was modified by deleting the treatment units after the anaerobic digestion. Chinese cabbage and Korean radish were selected as seeding plants in two sets of field irrigation experiments with various portions of ...

Plastic-Puglia: Watering your crops while saving resources
In summer, keeping a vegetable garden well watered means keeping an open tap like you haven’t seen since your last kegger in college. When the little rainfall in winter can make it seem like summer year-round, our finite resource such as water becomes ever more precious, in spite of the few rainstorms that did pass through in winter. Since the last few years, world has become ...
