** AWARDS ISSUED PRIOR TO JANUARY 20, 2025, WERE FUNDED UNDER PREVIOUS ADMINISTRATIONS AND MAY NOT REFLECT THE PRIORITIES AND POLICIES OF THE CURRENT ADMINISTRATION.** RESOURCE RECOVERY FROM AGRICULTURAL WASTES AND CONVERSION INTO VALUABLE PRODUCTS ARE CRITICAL FOR THE CIRCULAR ECONOMY AND CONTRIBUTE TO THE USDA'S GOAL OF SUSTAINABLE AGRICULTURE. THE MAJOR OBJECTIVES OF THIS PROPOSAL ARE TO SYNTHESIZE AMORPHOUS AND CRYSTALLINE CALCIUM PHOSPHATE (ACCP) NANOCOMPOSITE AS A NOVEL, 'INTELLIGENT' NANOFERTILIZER USING RECYCLED PHOSPHORUS FROM AGRICULTURAL WASTES AND TUNE THEIR PROPERTIES TO BEST MATCH PLANT NUTRITIONAL NEEDS. SYNTHESIZED PRODUCTS WILL BE TESTED IN GREENHOUSE AND FIELD TRIALS IN CORN AND SOYBEAN PLANTS AND SOILS AND MASS BALANCE, STABLE ISOTOPE TRACKING, AND MICROBIAL RESPONSES WILL BE PERFORMED TO FULLY UNDERSTAND THE FATE OF THE PHOSPHORUS IN SOILS AND CROPS. WE WILL USE NUTRIENT AND RESOURCE USE EFFICIENCIES TO COMPARE THE NEW PRODUCT WITH CONVENTIONAL FERTILIZERS USED IN AGRICULTURE. AT THE END OF THIS PROJECT, WE EXPECT TO DEVELOP A PROMISING 'INTELLIGENT' NANOFERTILIZER FOR SUSTAINABLE AGRICULTURE. ?
