You know SoilMoist, those polymer hydrogel granules:

That would be terribly expensive and probably not that helpful to your lawn. Soilmoist is designed for potted plants and small specialized flowerbeds. I would estimate its useful life at about two years, after which you would probably repot anyway.

I have written to the company several times to find out what happens to Soil Moist (how long it lasts, what it breaks down to) and they do not answer. I don't want to add anything unknown to the environment, so I have stopped using it, until I get some definitive answers.

Terra-Sorb, a similar product, lasts five years and breaks down into potassium

I did get a reply from the company today (JRM Chemical). They said it's good from three to five year.
Bummer. I hoped it would last for eons.
