2. DIF (technique) - Wikipedia

   en.wikipedia.org/wiki/DIF_(technique)

   DIF is a greenhouse technique involving temperature control for the purpose of controlling plant internode length and thus elongation rates. DIF's effectiveness has led to a reduction in the need and use of chemical plant growth regulators. Although many common greenhouse plants do react strongly to -DIF, there are some plants which show little ...

3. Controlled-environment agriculture - Wikipedia

   en.wikipedia.org/wiki/Controlled-environment...

   The greenhouse industry is the second largest component of the CEA industry but another quickly growing segment is the vertical farming industry. Controlled Environment Agriculture has the ability to produce crops all year round, with the possibility of increased yield by adjusting the amount of carbon and nutrients the plants receive. [8]

4. Greenhouse effect - Wikipedia

   en.wikipedia.org/wiki/Greenhouse_effect

   The greenhouse effect occurs when greenhouse gases in a planet's atmosphere insulate the planet from losing heat to space, raising its surface temperature. Surface heating can happen from an internal heat source (as in the case of Jupiter ) or come from an external source, such as its host star .

5. Greenhouse - Wikipedia

   en.wikipedia.org/wiki/Greenhouse

   These Korean greenhouses were the first active greenhouses that controlled temperature, rather than only relying on energy from the sun. [2] The design still included passive heating methods, such as semi-transparent oiled hanji windows to capture light and cob walls to retain heat, but the furnace provided extra control over the artificial ...

6. Polytunnel - Wikipedia

   en.wikipedia.org/wiki/Polytunnel

   Temperature, humidity and ventilation can be controlled by equipment fixed in the polytunnel or by manual opening and closing of vents. Polytunnels are mainly used in temperate regions in similar ways to glass greenhouses and row covers .

7. Pineapple mania - Wikipedia

   en.wikipedia.org/wiki/Pineapple_mania

   This technology would later allow pineapple growers to maintain consistent greenhouse temperatures, but the details of how to control the temperature of the soil remained to be worked out until the early 18th century when the seldom known techniques of using tanners' bark and consistent temperature regulation with the use of thermometers became ...

8. Climate-smart agriculture - Wikipedia

   en.wikipedia.org/wiki/Climate-smart_agriculture

   One quarter of the world's greenhouse gas emissions result from food and agriculture (data from 2019). [15] Farm animals' digestive systems can be put into two categories: monogastric and ruminant. Ruminant cattle for beef and dairy rank high in greenhouse gas emissions. In comparison, monogastric, or pigs and poultry-related foods, are lower.

9. Avoiding Dangerous Climate Change (2005 conference)
