**AWARDS ISSUED PRIOR TO JANUARY 20, 2025, WERE FUNDED UNDER PREVIOUS ADMINISTRATIONS AND MAY NOT REFLECT THE PRIORITIES AND POLICIES OF THE CURRENT ADMINISTRATION.** ANIMAL MANURES ARE A VALUABLE NUTRIENT SOURCE FOR CROP PRODUCTION IF WELL MANAGED. MANURE CHARACTERISTICS VARY SPATIALLY AND TEMPORALLY DEPENDING ON ANIMAL SPECIES, BEDDING USE, COLLECTION METHOD, TREATMENT, AND STORAGE METHOD. UNDERSTANDING MANURE COMPOSITION IS CRITICAL TO NUTRIENT MANAGEMENT PLANNERS, REGULATORS, ENGINEERS, AND FARMERS INTERESTED IN MANURE HANDLING AND PROCESSING. AVAILABLE MANURE CHARACTERISTIC TABLES ARE DECADES OLD AND DO NOT HAVE VALUES FOR DIFFERENT ANIMAL MANURE HANDLING SYSTEMS. ENGINEERS THAT WRITE STANDARDS AND HANDBOOK PUBLISHERS DO NOT HAVE THE RESOURCES TO COLLECT AND REPORT DYNAMICALLY CHANGING DATA. THEY RELY ON PUBLISHED RESEARCH TO ACCUMULATE BEFORE THE STANDARDS OR HANDBOOKS ARE UPDATED. MANURE COMPOSITION IS A CRITICAL PIECE OF NUTRIENT CYCLING ANALYSES FOR CROP AND LIVESTOCK SECTORS, WHICH IN TURN INFORM SUPPLY CHAIN SUSTAINABILITY DECISIONS AND ACTIONS. THIS PROJECT WILL DEVELOP PROCESSES FOR COLLECTING MANURE COMPOSITION DATA FROM COMMERCIAL AND UNIVERSITY LABS TO IMPLEMENT A SCALABLE AND DYNAMIC DATABASE AND MANAGEMENT SYSTEM FOR COLLECTING AND COMBINING MANURE ANALYSIS RESULTS FROM AROUND THE UNITED STATES. THE ULTIMATE GOAL IS TO THEN PROVIDE THIS DATA THROUGH TWO INTERFACES:ONE TO PROVIDE RESEARCH STAFF WITH A FLEXIBLE YET POWERFUL PORTAL TO INSPECT AND ANALYZE DATA, ANDANOTHER TO PROVIDE THE PUBLIC WITH A SIMPLE MEANS TO ACCESS AND DOWNLOAD DATASUMMARIES BY REGION.THE LONG-TERM OUTCOMES OF THIS PROJECT INCLUDE IMPROVED MANURE MANAGEMENT THROUGH INCREASED AND MORE UP-TO-DATE KNOWLEDGE OF MANURE COMPOSITIONOVER TIME AND BY LOCATION (REGIONS). THIS WILL RESULT IN BETTER USE OF MANURE NUTRIENTS, INCREASED PROTECTION OF ENVIRONMENTAL AND NATURAL RESOURCES, AND IMPROVEMENTS IN CONSUMER HEALTH AS FEWER POLLUTANTS FROM OVER-APPLICATION OF MANURE END UP IN OUR ENVIRONMENT. THE DATABASE IS DESIGNED TO REINFORCE THE PRACTICE OF MANURE SAMPLING BY MAKING THE TEMPORAL AND SPATIAL VARIABILITY OF MANURE EVEN MORE APPARENT.
