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.
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 detailed description of the proposed Solution addressing specific Technical Requirements presented in the Detailed Description of the Challenge. This description should be accompanied by a well-articulated rationale supported by literature/patent precedents.
- Experimental proof-of-concept data obtained as outlined in the Detailed Description of the Challenge.
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.
