A POTTING SOIL COMPOSITION COMPRISING (1) A POTTING SOIL MATRIX HAVING A CATION EXCHANGE CAPACITY OF AT LEAST 2 MILLIEQUIVALENTS PER 100 GRAMS AND IN INTIMATE ADMIXTURE THEREWITH (2) NUTRIENT-CHARGED, WATER-INSOLUBLE SYNTHETIC ION EXCHANGE RESINS, WHEREIN THE NUTRIENTS POTASSIUM, CALCIUM AND MAGNEESIUM ARE SUPPLIED IN CHEMICAL COMBINATION WITH CATION EXCHANGE RESINS, THE NUTRIENT PHOSPHORUS IS SUPPLIED AS ORTHOPHOSPHATE IN CHEMICAL COMBINATION WITH ANION EXCHANGE RESIN, THE NUTRIENT NITROGEN IS SUPPLIED IN AMOUNTS UP TO ONE-HALF AS AMMONIUM IN CHEMICAL COMBINATION WITH CATION EXCHANGE RESIN AND THE REMAINDER AS NITRATE IN CHEMICAL COMBINATION WITH ANION EXCHANGE RESIN; AND WHEREIN THE NUTRIENT-CHARGED, WATER-ONSOLUBLE SYNTHETIC ION EXCHANGE RESINS ARE SUPPLIED IN AMOUNTS SUFFICIENT TO PROVIDE FINAL WEIGHT CONCENTRATIONS IN THE POTTING SOIL COMPOSITION OF AT LEAST 375 P.P.M. OF POTASSIUM CALCULATED AS POTASSIUM OXIDE, 500 P.P.M. OF CALCIUM CALCULATED AS CALCIUM OCIDE, 150 P.P.M. OF MAGNESIUM CALCULATED AS MAGNESIUM OXIDE, 300 P.P.M. OF NITROGEN CALCULATED AS NITROGEN, AND 300 P.P.M. OF PHOSPHORUS CALCULATED AS PHOSPHORUS PENTOXIDE, WHEREIN P.P.M. IS WEIGHT CONCENTRATION IN SOIL MATRIX IN PARTS PER MILLION.
