Potential impacts of on-site greywater reuse in landscape irrigation
This study investigated the effects of irrigation with different types of waters on soil, plants, and public health. The test plant was ryegrass grown in 12 planters filled with sandy loam soil and irrigated with three types of waters (4 planters for each type): freshwater, raw domestic light greywater (GW), and treated domestic light GW. The sodium adsorption ratio (SAR), EC, pH and alkalinity ...

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 ...

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 ...

Protection of a slope along a road in a semi-arid region - Case Study
The challenge The road enlargement works in close proximity to residential areas have created particularly steep slopes. The local soil is composed of loess, materials with well-known characteristics in contact with water. A typical rainfall curve in those very dry areas, where the heavy rains, even rare, have resulted in very serious soil erosion. Slope with a steep inclination ...

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 ...

Distribution of moisture and salinity under deficit irrigation and irrigation water salinity in an alternative trickle irrigation system of tape
This study was performed to investigate the horizontal and vertical distribution of soil moisture and salinity using an alternative trickle irrigation system of drip tape. Four main treatments consisting of 100, 80, 70, and 60% of the plants’ water requirements and three sub-treatments of 2.1, 4.6, and 10.2 dS/m, were conducted. Following irrigation, the soil moisture and salinity ...

Assessment of climate change impact on crop yield and irrigation water requirement of two major cereal crops (rice and wheat) in Bhaktapur district, Nepal
Rice and wheat are major cereal crops in Nepal. Climate change impacts are widespread and farmers in developing countries like Nepal are among the most vulnerable. A study was carried out to assess the impact of climate change on yield and irrigation water requirement of these cereal crops in Bhaktapur, Nepal. Laboratory and soil-plant-air-water analysis showed silt-loam being the most ...

Scalewatcher Banishes Limescale In Gardens And Greenhouses
In hard water areas, automated watering systems, sprinkler irrigation systems and greenhouse-misting systems clog with limescale, plant leaves develop white scale deposits and over-spray causes limescale build-up on greenhouse windows. Scalewatcher North America, manufacturers of the original, patented and award-winning computerized electronic water-conditioner, Scalewatcher®, has a range of ...

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 ...

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.) ...

Irrigating with saline or seawater
Currently, agriculture uses seventy percent of the freshwaters, globally. Available freshwater sources will not be enough to increase food production to feed growing populations in the coming decades. Therefore, there is a concerted effort to grow crops with seawater. Hence, scientists are investigating the various challenges involved in growing plants with saline water. These include greenhouse ...

The use of treated wastewater and fertigation in greenhouse pepper crop as affecting growth and fruit quality
The performance and suitability of tertiary treated wastewater (TW) and/or fertigation (F) in pepper plants were studied over a 4-month period in greenhouse conditions. Four treatments were used consisting of (1) water, (2) water + F, (3) TW, and (4) TW + F. The F and/or TW application increased plant height and plant biomass compared with the control plants (irrigated with water) ...

AquaCrop—The FAO crop model to simulate yield response to water: III. Parameterization and testing for maize
The first crop chosen to parameterize and test the new FAO AquaCrop model is maize (Zea mays L.). Working mainly with data sets from 6 yr of maize field experiments at Davis, CA, plus another 4 yr of Davis maize canopy data, a set of conservative (nearly constant) parameters of AquaCrop, presumably applicable to widely different conditions and not specific to a given crop cultivar, was evaluated ...

Soil Moisture Terminology
Soil Moisture Terms. What do they mean and how do we use them? By the end of this short article you will hopefully understand the following statement. “For good crop growth, maintaining water above stress point will maximise vegetative growth. Setting a refill point above stress point will ensure there is always readily available water for the crop. Replacing ...

Lg Sonic Ultrasonic Algae and biofilm control for irrigation case study
Water used for irrigation can contain high levels of nutrients, some of these nutrients are beneficial for the plants watered, but can also lead to extensive algal growth. Algae in irrigation tanks can clog the irrigation system and can also be spread over the irrigated area. In addition, some types of fungus, also present in these waters, can be harmful for the plants grown. Therefore the ...
