Energy and exergy analyses of greenhouse fish drying
In present study, an energy analysis has been used to predict fish surface temperature, greenhouse room air temperature and moisture evaporated during greenhouse drying of Prawn under natural and forced convection conditions. The predicted values showed fair agreements with experimental values (coefficient of correlation, r = 0.94-0.99; root mean square percent deviation, e = 2.4-10%). Analytical ...

Eggplant- Saudi Arabia - Case Study
Eggplants in Saudi Arabia are usually planted in sandy soils inside a greenhouse with temperatures rising upt to 50°C. With the utilization of ecotube, the harvest could be done two weeks earlier and the biomass was 48% higher in comparison to conventional drip irrigation systems. All while saving aproximately 90% water. Most of it due to no evaporization. In the picture, the plants on the ...

The state of greenhouse gases in the atmosphere using global observations through 2006
The latest analysis of data from the WMO-GAW Global Greenhouse Gas Monitoring Network shows that the globally averaged mixing ratios of carbon dioxide (CO2) and nitrous oxide (N2O) have reached new highs in 2006 with CO2 at 381.2 ppm and N2O at 320.1 ppb. Atmospheric growth rates in 2006 of these gases are consistent with recent years. The mixing ratio of methane (CH4 ) remains almost unchanged ...

8 Types Of Agricultural Sensors For Best Greenhouse Monitoring Systems
Background A greenhouse is a closed environment that provides optimal conditions for plant growth and promotes plant growth by controlling indoor and outdoor environments. A complete greenhouse remote monitoring system first detects indoor environmental elements through various sensors and then uploads the measurement signals to the control platform through wired or wireless methods, and the ...

Towards theoretical multiplicity for the governance of transitions: the energy-producing greenhouse case
Transition management has become an important topic in scientific research on sustainable development over the last decade. A recurring question is whether, and if so how, transitions towards sustainability can be governed. In this paper we address this question by theoretically comparing transition management theory with a number of related theories on governing societal change, such as ...

Modelling water requirements of greenhouse spinach for irrigation management purposes
Estimating water requirements of plants cultivated in greenhouse environments is crucial, both for the design of greenhouse irrigation systems and the improvement of irrigation scheduling. Spinach is one of the main vegetables sold as ‘ready-to-eat’ bagged produce; it is very sensitive to water stress and thus requires accurate irrigation. In this work, a water balance model simulating the ...

Seed Seedling Bluetooth Temperature Recorder
Seed seedlings have strict requirements on environmental temperature. Only at a suitable temperature can seeds grow normally. Bluetooth temperature loggers are used for temperature monitoring and can help ensure that seeds germinate and grow under the right temperature conditions. Seed seedlings are generally carried out in greenhouses, which can effectively control the environmental temperature ...

Simulating the Effect of Climate Change on Agriculture
Increased atmospheric CO2 levels and climate change are believed to contribute to extreme weather conditions, which is a major concern for many. And beyond extreme events, global warming is also predicted to affect agriculture.1,2 While climate change is expected to affect agriculture and reduce crop yields, the complete effects of climate change on agriculture and the resultant human food ...

Energy use and greenhouse gas emissions and related improvement options of the broiler chicken meat supply chain
Energy consumption and the climate–change impact (i.e., carbon footprint) of a typical Finnish broiler chicken fillet product were studied using a supply–chain integrated life cycle assessment method. All essential production stages from parent stock and production of farming inputs to product distribution and sales in retail stores were included in the assessment. The results of the ...
