The Seeker is looking for economical methods to combine ammonium thiosulfate solutions (40% water) with solid urea/ammonium based fertilizers to produce a product that can be applied on the field using standard solid fertilizer based equipment.
This is a Reduction-to-Practice Challenge that requires written documentation and experimental proof-of-concept data.
Environmentally friendly thiosulfates are becoming increasingly popular agricultural fertilizers because they not only provide sulfur in a plant-accessible form but they are also known to have nitrogen stabilizing properties. Ammonium thiosulfate (ATS) is a popular choice since it provides nitrogen in addition to sulfur but while pure ammonium thiosulfate is a dry crystalline solid, commercial scale production of ATS results in an aqueous solution that contains approximately 40% water. ATS is not easily combined with solid nitrogen containing fertilizers and the Seeker desires an innovative way to economically combine ATS with urea/ammonium containing solid fertilizers to produce a final product that can be applied using standard solid fertilizer based equipment.
The submission to the Challenge should include the following:
The Challenge award is contingent upon theoretical evaluation and experimental validation of the submitted Solutions by the Seeker.
To receive an award, the Solvers will have to transfer to the Seeker their exclusive Intellectual Property (IP) rights to the solution.
Submissions to this Challenge must be received by 11:59 PM (US Eastern Time) on 17-Jan-2022.
Late submissions will not be considered.
What is InnoCentive?
InnoCentive is the global innovation marketplace where creative minds solve some of the world's most important problems for cash awards up to $1 million. Commercial, governmental and humanitarian organizations engage with InnoCentive to solve problems that can impact humankind in areas ranging from the environment to medical advancements.
What is an RTP Challenge?
An InnoCentive RTP (Reduction to Practice) Challenge is a prototype that proves an idea, and is similar to an InnoCentive Theoretical Challenge in its high level of detail. However, an RTP requires the Solver to submit a validated solution, either in the form of original data or a physical sample. Also, the Seeker is allowed to test the proposed solution. For details about treatment of Intellectual Property (IP) rights, please see the Challenge Specific Agreement.
