  2. Sodium polyacrylate - Wikipedia

    en.wikipedia.org/wiki/Sodium_polyacrylate

    Super-absorbent polymers (SAP) similar to sodium polyacrylate were developed in the 1960s by the U.S. Department of Agriculture. [3] Before the development of these substances, the best water absorbing materials were cellulosic or fiber-based like tissue paper, sponge, cotton, or fluff pulp.

    en.wikipedia.org/wiki/Water_crystal_gel

    Water gels are used for: Supplying water to small animals as an alternative to supplying water in a dish. Some small animals tend to fall into dishes of water and drown. [citation needed] Watering or potting plants. [1] In vases of cut flowers; Use in gardens to save water. Used as ammunition for gel blaster toy guns. Usually came in 7– 8 mm ...

  4. Absorption of water - Wikipedia

    en.wikipedia.org/wiki/Absorption_of_water

    Absorption of water-Plants generally absorb capillary water from the soil through their roots. The diffusion pressure deficit in a cell of a leaf is developed because of transpiration then water from the adjacent cell moves towards the cell in the same way diffusion pressure deficit is developed in the second cell and water moves to it from the ...

  5. Superabsorbent polymer - Wikipedia

    en.wikipedia.org/wiki/Superabsorbent_polymer

    Water-absorbing polymers, which are classified as hydrogels when mixed, [3] absorb aqueous solutions through hydrogen bonding with water molecules. A SAP's ability to absorb water depends on the ionic concentration of the aqueous solution. In deionized and distilled water, a SAP may absorb 300 times its weight [4] (from 30 to 60 times its own ...

    Promptly remove the plant from the water basin after 30 minutes so it does not become waterlogged. Allow excess water to drain away over a sink. Replace the plant in its usual growing location.

  7. Soil water (retention) - Wikipedia

    en.wikipedia.org/wiki/Soil_water_(retention)

    Available water is that which the plants can utilize from the soil within the range between field capacity and wilting point. Roughly speaking for agriculture (top layer soil), soil is 25% water , 25% air , 45% mineral , 5% other; water varies widely from about 1% to 90% due to several retention and drainage properties of a given soil.

  8. Hygroscopy - Wikipedia

    en.wikipedia.org/wiki/Hygroscopy

    Deliquescent materials are sufficiently hygroscopic that they dissolve in the water they absorb, forming an aqueous solution. Hygroscopy is essential for many plant and animal species' attainment of hydration, nutrition, reproduction and/or seed dispersal.

  9. Plant nutrients in soil - Wikipedia

    en.wikipedia.org/wiki/Plant_nutrients_in_soil

    As plants absorb the nutrients from the soil water, the soluble pool is replenished from the surface-bound pool. The decomposition of soil organic matter by microorganisms is another mechanism whereby the soluble pool of nutrients is replenished – this is important for the supply of plant-available N, S, P, and B from soil.
