    en.wikipedia.org/wiki/Alternate_wetting_and_drying

    [13] [14] CH 4 is produced by the anaerobic decomposition of the organic material in the wet/flooded paddy field. Allowing to drop water level below soil surface removes the anaerobic condition for some time until re-flooded and pauses the production of CH 4 from the rice field for several times and, hence, reduce the total amount of CH 4 ...

  3. Hydrogel agriculture - Wikipedia

    en.wikipedia.org/wiki/Hydrogel_agriculture

    Hydrogel agriculture technology uses insoluble gel-forming polymers to improve the water-holding properties of different soils, such as clays and sandy loams. This can increase water-holding and water use (up to 85% for sand), improve soil permeability, reduce the need for irrigation, reduce compaction, soil erosion , and leaching, and improve ...
