Process for manufacturing organic fertilizers containing water soluble nitrogen from humic materials

Claim 1

A PROCESS FOR MAKING A LIGHT-WEIGHT ORGANIC FERTILIZER COMPRISING THE STEPS OF COMBINING NUTRIENT INGREDIENTS AND SOLUBLE LIGNEOUS MATERIALS WITH WATER IN AN AMOUNT EQUAL IN WEIGHT TO THE TOTAL ANHYDROUS WEIGHT OF THE COMBINED INGREDIENTS, COOKING THE MASS AT A TEMPERATURE OF APPROXIMATELY 220*F. TO 250*F. UNDER 10 TO 15 POUNDS PRESSURE FOR APPROXIMATELY 40 MINUTES, MAINTAINING LESS THAN A PH OF 7, COOLING THE MATERIAL TO 180*F. WHILE UNDER PRESSURE, DEPRESSURIZING AND DRYING THE MASS, ADDING TO THE RESULTING MASS A MARL IN THE AMOUNT OF 40% OF THE ORIGINAL WEIGHT OF THE COMBINED NUTRIENT AND LIGNEOUS MATERIALS, ADDING AN ACID SOLUTION TO REDUCE THE PH TO 4, ADDING WATER TO THE MASS IN AN AMOUNT TO CREATE A SLUDGE, THEN DEHYDRATING THE SLUDGED MASS BY APPLYING A TEMPERATURE OF 160*F. SO THAT THE RESULTING DRIED FERTILIZER CONTAINS LESS THAN 5% MOISTURE.
