It’s so easy to buy anything you want on internet.But sometimes you will find the prices are so different for the products looks the seem. Now we’ll talk about the mainly differences of super absorbent polymers for agriculture.
First, let’s watch the video which introduce super absorbent polymer for plants as follows,
The way to help plants growing is amazing right ? Then the problem is coming –Is that okey to use this kind gel for all our plants / crop without any pollution?
There are two kinds of polymer can absorb water and turn to gel:sodium polyacrylate and potassium poyacrylate. First one is the polymer in the video and the other one is the professional polymer for common plants’ usage.
Here are the differences:
-Sodium polyacrylate ‘s Sodium may let soil hardened when the operating frequency is high.
-Potassium polyacrylate’s Potassium has fertilizer efficiency for plant.
2.Water Gel Characteristic
-Sodium polyacrylate’s water gel is softer and sometimes will let the root rot.
-Potassium polyacrylate’s water gel is firm and never sticky.
-Sodium polyacrylate the mainly material of the disposable products such as paper diapers,Lady sanitary napkin.
-Potassium polyacrylate :the period of validity can last more than 3 years in soil.
Potassium polyacrylate ‘s price is about 2 times as much as sodium polyacrylate’s. And we do need to clear them before buy.
