Seawater greenhouse plan for Jordan
Seawater greenhouses, solar power plants and other new green technologies will be brought together in Jordan in an attempt to turn its desert into a producer of crops, fresh water and electricity. The governments of Jordan and Norway signed an agreement last month (11 January) to build a 20-hectare demonstration centre near Aqaba on the Red Sea. They will work with the Aqaba Special Economic ...

CHP Greenhouses Make Growing Even Greener
Bearing little resemblance to a typical farm, modern large greenhouses are, in reality, complex, high-tech factories that produce food and other crops. A natural gas Cat® or MWM™ generator set produces electrical power for the greenhouse needs, and any excess electricity can be sold to the utility company and fed back to the grid. The extra heat from the engine is collected to keep the ...

Using ventilated latent heat converters to reduce botrytis pressure
Controlling the humidity insfcle a controled environment e one of the most discussed concerns amongst greenhouse growers. A solution that is more often notic ed by growers are the so c aled VentJated Latent Heat Converters (VLHC); These units extract humid air from inside the greenhouse and convert water vapour into water and heat by blowing the air through a matrix of desiccant-filled elements ...

Seeing is believing as scientists trace greenhouse effect
Government scientists in the US say they have directly observed for the first time the greenhouse effect in action, while monitoring the way carbon dioxide in the Earth’s atmosphere absorbed increasing amounts of thermal radiation from the surface. Their measurements, taken over a period of 11 years in Alaska and Oklahoma, confirm predictions made more than 100 years ago, and repeatedly ...

Optimal substrate moisture content determined for high-quality bedding plants
The bedding plants sold in retail outlets are typically grown in greenhouse production environments where professionals can monitor irrigation, light, and temperature. When the greenhouse-grown plants reach the retail market, however, they are often subjected to a range of less-than-ideal light levels, temperatures, and irrigation schedules that can be detrimental to plant quality and vigor. ...

Preparing Plants for our Future Climate
Planning is something we all do. As individuals, we may be planning for next weekend or our future retirement. Farmers and plant breeders are also planning for a future. The crops we currently depend on will need grow under different conditions – due to climate change. Some weather conditions are easy to control. Scientists can set the temperature in a greenhouse and control how much ...

GM rapeseed could reduce fertiliser usage
Nitrogen fertiliser used in crop production is a substantial source of environmental pollution, contributing to around one third of the total greenhouse gas emissions from the world's agricultural sector. Recent research on a genetically modified (GM) variety of rapeseed, which has been made more nitrogen-efficient, suggests that yields comparable with conventional varieties can be obtained using ...
