VPI successfully apply UPSTO patent for “Smart fertilizers and method of manufacturing and using the same”
Abstract
On August 23rd, 2022, the Vietnam Petroleum Institute (VPI) successfully registered the United States Patent and Trademark Ofice (USPTO) application 17/821529 for “Smart fertilizers and method of manufacturing and using the same”
Accordingly, an object of the present invention is to provide smart fertilizers and method of using and manufacturing the same that include a nano carbon solution mixed with nanocomposite hydrogels at predetermined percentage weight or volume ratio (% w/w or % v/v). The resulted smart fertilizers are characterized by having biosensors for detecting various endogenous stimuli such as electricity conductance (EC) or salinity, soil pH degree caused by the release of ATPase H+ from the plant roots and in bioactuators for chemically reacting with the surrounding hydrogen ions to release the nutrients when the biosensors detect the stimuli conditions.
