In Bowen, Queensland, in 2010, Hibrix was compared with a high NPK mineral fertiliser program for the production of maize cv. Hycorn 675IT on an alluvial sandy loam soil irrigated via sub-surface drip tape. At commercial harvest, cobs from 20 randomly selected plants per plot from were harvested, weighed and the length, girth at the cob base and length of tip not filled with kernels was measured. ...

Overexploitation of groundwater (GW) in the recent past is a well-known fact for the Punjab and Haryana region of India, as reported by several studies using satellite-based gravity anomaly from the Gravity Recovery and Climate Experiment mission and also by using observed data. This decline in GW has enforced the Punjab Preservation of Sub-Soil Water Act 2009, and resulted in change in rice ...

Energy saving and maximum efficiency are the cardinal points of agriculture 2.0. Today, through the micro irrigation and subsurface irrigation, agricultural production reached a high level of efficiency that assures quality and quantity. “Micro-irrigation”, or drip irrigation, is a method which allows the farmer to give the same amount of water to the ...

Water shortage has encouraged the quest for alternative sources of water for food production and agricultural development. Recycled water (RW) is one of the most available water resources with great potential for use in farm irrigation. This experiment was carried out to investigate the use of RW as the irrigation source and its application method, subsurface leaky irrigation (SLI) system or ...

North China Plain is one of the most important grain-producing areas in China. Because of unevenly distributed precipitation in this semi-arid area, crop production largely relies on underground blue water (UBW) to irrigate, overexploitation of which causes a lot of environmental problems. In this paper, we first defined the representative division of winter wheat irrigation water production ...

Scarcity of water, major critical concern in arid areas, has led to the use of low–quality irrigation water in agriculture in most of arid climate areas. The quality of water used for agriculture has to be reduced to a sustainable level that is also adapted to the environment. This paper presents the performance of a pilot condensation irrigation (CI) solar system in Tunisia under arid ...

Irrigated area in the Mid-South USA continues to increase and now totals four million ha. Because of low available water holding capacities and shallow root-limiting layers in many soils, irrigation management is difficult. Water quality and water use efficiency impacts under irrigation are poorly understood, but comprehension is necessary if conversion from groundwater to surface water supplies ...

Water use technical efficiency (WUTE) and three definitions of water use economic efficiency (WUEE) were estimated for the four river sub-basins that encompass the 13 irrigation districts in Southern Alberta over a 5-year period: 2004–08. The average level of WUTE varied from 3.5 to 6.2 Mt dam−3. The gross economic value of crop production varied from Canadian (C)$345 to ...

The book entitled Water Quality, Soil and Managing Irrigation of Crops comprises three sections, specifically: Reuse Water Quality, Soil and Pollution which comprises five technical chapters, Managing Irrigation of Crops with four, and Examples of Irrigation Systems three technical chapters, all presented by the respective authors in their own fields of expertise. This text should be of interest ...

Nothing spells the death of a subsurface drip irrigation (SDI) system taster than root intrusion. With more growers placing drip irrigation lines below the soil surface, the need for a better understanding of how to keep roots out of drip emitters has also become more important. Work done at The ("enter for Irrigation Technology (GIT) over the past 10 years has given us some insight into how to ...

Abstract California has become the leading dairy products producing state in the USA. This has resulted in farms commonly milking several thousand cows per day. The care and feeding of the animals has produced large waste streams commonly collected and stored in lagoons. Environmentally safe handling and reuse of the lagooned wastewater is the objective of this study. A system of ...

Health risks posed on consumers due to the use of agricultural products irrigated with reclaimed wastewater were assessed by numerical simulation. The analysis is based on defining of an Exposure Model (EM) which takes into account several parameters: (i) the quality of the applied wastewater, (ii) the irrigation method, (iii) the elapsed times between irrigation, harvest, and product ...

Although subsurface drip (SSD) is used as a water-efficient alternative to overhead irrigation in many crops, the effects of SSD on the distribution of bolls on cotton plants (Gossypium hirsutum L.) have not been thoroughly examined. The purpose of this study was to add to the current knowledge about the effects of SSD on cotton yield dynamics. Cultivar DP 488 BG/RR was grown in three studies ...

Waste handling systems for confined swine production in the upper South (approximately 32–37° N and 79–93° W) depend mainly on anaerobic lagoons and application of the waste effluent to cropland. The main objective of this study was to evaluate the quality of ‘Coastal’ bermudagrass [Cynodon dactylon (L.) Pers.] hay receiving effluent generated from a raw swine waste treatment system designed to ...

Subsurface drip (SSD) is used as a water-efficient alternative to overhead irrigation in many crops. This study compared soil water, water use, crop maturity, lint yield, and fiber quality of cotton (Gossypium hirsutum L.) grown with SSD to cotton grown with overhead irrigation. Three experiments were conducted at two Georgia locations in 2004 and 2005. Treatments consisted of overhead irrigated, ...

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. ...

The rich green swathes of the new extension of Omaha Golf Course are visual proof of high technol¬ogy at its best, enabling lush ungated grass to survive all year round despite being bordered on two sides by ocean and estuary and buitt on a combination of sand dunes and wetlands. It is a world first, and an international success story for the three main players - local drainlayer Ivor Jones, ...
