Using hydrophilic polymers to control nutrient release

A comparison of the use of different sources of nanoscale iron particles on the concentration of micronutrients and plasma membrane stability in sorghum

“…In the greenhouse experiment, it was reported that some of polymeric hydrated sources provides small environment within the root zone which keeps Iron sulfate available to plants compared with its non-polymeric use (Mikkelsen, 1994).…”

Yield and Physiological Parameters of Maize as Influenced by the Application of Super Absorbent Polymer and Mulching Under Rainfed Conditions

“…Pusa hydrogel is a novel semisynthetic superabsorbent polymer developed by the Indian Agricultural Research Institute. Hydrogels are safe and non-toxic and it will finally decompose to carbon dioxide, water and ammonia without any residue (Mikkelsen, 1994).…”

Growth and development of Jatropha curcas seedlings using Terracotem soil conditioners under different irrigation levels

“…The synthetic SAPs that are widely used in agriculture are mainly polyacrylamide and polyacrylate polymers (Mikkelsen, 1994). One of the commercial products available is Terracottem®.…”
