Self-Cleaning Irrigation Water Filters
One of the critical components of successful agriculture is irrigation, which ensures that crops receive the water they need to thrive. However, using untreated or impure water for irrigation can have detrimental effects on crops and the environment. Self-cleaning irrigation water filters have emerged as a groundbreaking solution to this problem. The Importance of Self-Cleaning Irrigation Water ...

A model approach to evaluate irrigation system water balance: an example from the Gediz Basin, Turkey
An increase in the amount of water used for agriculture has resulted in the need for water savings and measurements in the agricultural sector. With the increasing competition for water, not only should irrigation water be considered, but also an approach encompassing the total water balance is necessary. A clear understanding of all the components of the water balance is essential so as to ...

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 ...

Agriculture and economics in the Water Framework Directive: progress and limitations
Agriculture is having an increasing impact on water resources in Spain, both from a quantitative (consumption) and qualitative (pollution) perspective. Therefore, the implementation of the Water Framework Directive (WFD) will have a great impact on this sector. In fact, new river management plans aim to reduce these pressures through the implementation of programmes of measures. These instruments ...

Effects of treated municipal wastewater on fluctuation trend of leaf area index and quality of maize (
Zea mays )The effect of primary-treated municipal wastewater (TMWW) on the leaf area index (LAI) and quality of maize (Zea mays) was studied in comparison to the clean irrigation water (control). The experiment was based on a randomized block design with four replicates, and it was conducted in a field experiment in Aligoudarz (Iran). Irrigation was applied with five different methods as treatments: T1: ...

The efficacy of disinfectants against plant pathogens
In late 2015, a journal article from the European Journal of Plant Pathology was published on research regarding the efficacy of different disinfectants against plant pathogens in irrigation water. All testing as done by the Department of Primary Industries here in Australia for the horticulture and agriculture industries. The disinfectants tested included chlorine, chlorine dioxide (using our ...

HDPE Canal Liner for Irrigation Water Project in China
HDPE canal liner is the widely used geomembrane liner products and the essential lining system for the efficient use of water resources due to their features of lowest permeability, excellent anti-seepage and ultra stress crack capacity, etc. More than 45% of water used in the agriculture would be lost due to seepage. HDPE canal liner is an affordable solution to prevent water loss of ...

Evaluation of yield, quality and crop water stress index of sugar beet under different irrigation regimes
This study was carried out to evaluate the use of the crop water stress index (CWSI) for irrigation scheduling of sugar beet for two years under the semi arid climate of Iran. Statistical relationships between CWSI and yield, quality parameters and irrigation water use efficiency (IWUE) were investigated. Irrigations were scheduled based on 100 (I100), 85 (I85), 70 (I50) and 0% (I0) of plant ...

Seasonal ammonia losses from spray-irrigation with secondary-treated recycled water
This work examines ammonia volatilization associated with agricultural irrigation employing recycled water. Effluent from a secondary wastewater treatment plant was applied using a center pivot irrigation system on a 12 ha agricultural site in Palmdale, California. Irrigation water was captured in shallow pans and ammonia concentrations were quantified in four seasonal events. The average ammonia ...

Irrigation Application Management
The Irrigation Applications management takes all measurements of the inlet discharge and pressure at the pivot point and pivot end. Especially when the ground is uneven, where we take readings at the highest point. Preferably, this pressure value should be at least 5 PSI higher than the rated value of the pressure regulator, to ensure safety and proper operation, as the regulator must be ...

Behavior of atrazine in Limited Irrigation Cropping Systems in Colorado: Prior use is important
Glyphosate-resistant (GR) corn may be a major component of new cropping systems to optimize the use of limited irrigation water supply while sustaining production. Because atrazine is an important tool for residual weed control in GR corn, we examined atrazine binding to soil, dissipation, movement, and early season weed control in limited and full irrigation cropping systems. These systems ...

Flow monitoring for golf course irrigation - Case Study
“We are all talking about the price of oil, but it's water we'll be fighting for in the future” Summerheights Golf Links in Cornwall, Ontario draws irrigation water from the South Raisin River. Flow rates in the river can become very low during dry periods so water extraction is regulated and monitored closely. Under a water extraction permit issued by the Ministry of The ...

Improved Agricultural Irrigation Scheduling Using a Soil Water Content Sensor - Case Study
Abstract The key to scheduling irrigation timing and amounts is determining moisture depletion in the soil. Two common methods include tracking crop evapotranspiration (ETc) and tracking the water content with a sensor buried in the soil. In Colorado, a popular online tool that estimates the ETc for a variety of well-irrigated crops is the Colorado Agricultural Meteorological Network (CoAgMet). ...

Sprinkler irrigation changes maize canopy microclimate and crop water status, transpiration, and temperature
During a sprinkler irrigation event some water is lost due to wind drift and evaporation (WDEL). After the irrigation event, plant-intercepted water is lost due to evaporation. The water lost causes microclimatic changes which could result in positive or negative plant physiological changes. We studied the microclimatic and physiological changes on two fields grown with maize (Zea mays L.) ...
