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. ...

Constructed wetlands (CWs) represent low-cost technology for the treatment and reuse of wastewater in urban areas. This study aimed to evaluate the pollutant removal efficiency of a CW system and to assess the effects of irrigation using treated urban wastewater on soil and on two warm-season turf species. The research was carried out in Sicily (Italy) on a pilot-scale horizontal subsurface ...

For three weeks every month, Ray Archuleta captivates audiences with a few handfuls of soil. He begins with two clumps, dropping them into water. The soil from a farm where the soil isn’t tilled holds together, while the tilled soil immediately disperses, indicating poor soil structure. Next, volunteers from the audience — mostly farmers and ranchers — pour water over a soil ...

The Site 9 of the AquaNES project in Agon-Countainville (France) uses secondary effluent after reed bed and sand dune filtration for golf course irrigation in a coastal area. The underlying aquifer is prone to salinization. The study of Agon-Countainville site will demonstrate how innovative water quality monitoring and modelling linked to data management and communication, facilitates an ...

Management and scheduling of irrigation water requires consideration of evapotranspiration, one of the most important hydrological variables. This study investigates the variations in the daily potential evapotranspiration (ET0), and its aerodynamic (ETa) and radiometric (ETr) components in three areas (western, central and eastern) of the Inner Mongolia Autonomous Region ...

Rainwater conservation and soil erosion prevention are vital for the economic and financial sustainability of dry land agriculture. An integrated watershed development programme is thus a means of achieving these goals. Presently, integrated watershed management is receiving worldwide recognition as an effective model for watershed planning. A watershed is considered the basic geographical ...

Agriculture plays an important part in the food chain and water resources for agriculture are essential. A problem is that the water transport systems present low efficiencies in practice. Crop yields must be optimized, and the goal of an operational water manager is to deliver water to irrigation sites accurately and efficiently. In order to fulfill this objective, we propose a centralized ...

The effect of two different water sources (treated waste water and lake water) used for irrigation on the soil geochemical properties and the fruit quality parameters of the Lohan guava were studied. The fruits' physical attributes, physicochemical attributes, nutritional attributes, mineral content as well as consumers’ acceptance were evaluated. The properties of the different water sources ...

Water is an increasingly scarce and valuable resource. It is generally accepted that there is a finite supply of water. As economies grow there is an increasing demand for water. The application of water to agricultural lands for irrigation is one of the essential uses of this natural resource in many areas. There is competition among agriculture, industry, and human consumption for the ...

Water pricing policy is believed to be an efficient method for addressing the water scarcity problem in China. The motivation of this study is to provide a better understanding of how reducing irrigation subsidies impacts farming sectors and rural households. We apply a Computable General Equilibrium model to simulate the irrigation water and irrigation subsidy in 16 provinces. The results ...
