Is Solarisation a word?
Solarisation is a phenomenon in photography in which the image recorded on a negative or on a photographic print is wholly or partially reversed in tone. The term is synonymous with the Sabattier effect when referring to negatives, but is technically incorrect when used to refer to prints.
What is the function of solarization?
Solarization is a chemical-free way of controlling pests such as pathogenic microorganisms (mainly fungi, bacteria, and nematodes), insects, and wild plants in the soil before crops planting (Katan, 1987; McGovern and McSorley, 1997; Gill et al., 2009).
What is meant by soil Solarisation?
Soil solarization is a non-chemical environmentally friendly method for controlling pests using solar power to increase the soil temperature to levels at which many soil-borne plant pathogens will be killed or greatly weakened. Soil solarization is dependent upon time, temperature, and soil moisture.

- Clear the area of plants and debris.
- Water the soil deeply until it is wet.
- Cover the area with clear plastic (such as 1 to 4 mil painter’s plastic).
- Bury the plastic edges in the soil to trap the heat.
- Leave the plastic in place for at least 4 weeks in the hottest part of the summer.

What do you use for solarization?
In general, transparent or clear plastic is most effective for solarization, as the heating rays from the sun will pass through the sheet and be trapped to heat the soil below. Usually black plastic is less effective because it absorbs and deflects part of the heat, rather than trapping as clear plastic does.
How is solarization done?
Soil solarization is an environmentally friendly method of using the sun’s power to control pests such as bacteria, insects, and weeds in the soil. The process involves covering the ground with a tarp, usually a transparent polyethylene cover, to trap solar energy (Fig. 1).
What do you know about soil erosion?
In this process, the soil particles are loosened or washed away in the valleys, oceans, rivers, streams or far away lands. This has been worsening due to human activities such as agriculture and deforestation. Soil erosion is a continuous process that occurs either slowly or at an alarming rate.
Why is it called posterize?
Posterized is North American slang derived from an action in the game of basketball, in which the offensive player “dunks” over a defending player in a play that is spectacular and athletic enough to warrant reproduction in a printed poster.
Which is the best definition of solarisation?
