1. Is there a way to determine how much water the hydrogel will take?
2. Is there a way to determine if chemicals are stored in the soil and returned to the plant?
3. Has a special method been developed?
"Shokhrukh Abdullaev asked: 1. Is there a way to determine how much water the hydrogel will take?"
- Yes. Dry the gel, weigh it (establish the tare weight), hydrate it with water, weigh it again for the answer.
Dear Shokhrukh Abdullaev, the first point by measuring swelling capacity, the second by monitoring the release according to the basic hydrogel structure and the soil environment where it is to be applied, and the third point, yes various techniques are followed to evaluate the performance in such an application. Please check the following documents. My Regards

Shohruh Zafar o'g'li Abdullayev For the release of nutrient from the hydrogel can look into this literature. They have studied model drug release from a hydrogel patch. https://www.mdpi.com/1999-4923/11/5/209
Dear scientists! Thank you so much for your advice on my questions!
Has the reaction of the hydrogel to various salts in the soil been studied?
