PAST GRANULATION IN THE USA

INTRODUCTION OF REGIONAL GRANULATION PLANTS IN THE EARLY 1900’SAVAILIBILITY OF STANDARD GRADE FERTILIZER MATERIALS AND LIQUID INGREDIENTSNEED FOR HOMOGENEOUS MIXTURE THAT COULD BE EASILY HANDLED AND SPREADDRUM GRANULATION ANSWERED THESE NEEDSPRODUCTION RUNS OF LOW ANALYSIS GRADES SUCH AS TRIPLE 8 , 3-9-18, AND 4-12-12MID-1960’S GRANULAR MATERIALS SUCH AS MAP AND DAP BECAME READILY AVAILABLEBULK BLENDING DOMINATED GRANULATION

Europe

WESTERN EUROPEAN MARKETLARGE DEMAND FOR HOMOGENEOUS NPK FERTILIZERSLARGE SCALE GRANULATION PLANTS DEVELOPED BEFORE GRANULATION IN THE USA AND CONTINUE TODAYFACILITIES PRODUCING UP TO 2 M TONS OF NPKS PER YEARVERY LARGE PRODUCTION RUNS WITH NO ECONOMIC DRIVE TO MEET NICHE MARKETSSLOWLY INCREASING BULK BLENDING MARKET

3

EASTERN EUROPEAN MARKETLITTLE DEVELOPMENT OF BULK BLENDING DUE TO LACK OF AVAILIBILITY OF GOOD PHYSICAL QUALITY INGREDIENTS OR EFFICIENT SPREADING EQUIPMENTTRADITION FOR HOMOGENEOUS FERTILIZERSHIGH PRICED EXPORT MARKETS FOR ANY QUALITY GRANULAR INGREDIENTSAVAILIBILITY OF BASIC NON-GRANULAR MATERIALSRELATIVELY INEXPENSIVE ON A “PER UNIT NUTRIENT BASIS”GRANULAR NPKS FROM REGIONAL GRANULATION PLANTS MORE ECONOMICAL
