AMENDED (MOLLY) VERSUS NON-AMENDED BRZ™ ZEOLITE

JANUARY 2004, BASED ON GROW TESTS 

RECOMMENDATIONS

  • Grow tests conducted in the grow chamber at the BRZ™ lab have indicated definitive recommendations as follows:

  • The application of non-amended zeolite to a soil will adsorb the nitrogen and nutrients and the plants will not do as well as the control. After a period of time and depending on the soil nutrients, the nutrient level of the zeolite will reach equilibrium with the soil. The plant with the help of the mycorhizomes will then release the nutrients from the zeolite after a period of time.

  • The application of non-amended zeolite to a soil that is deficient in nitrogen will have a detrimental impact on plant growth, because the zeolite competes initially for the nitrogen.

  • Non-amended zeolite can be sold as long as it is amended with nitrogen prior to use. This should be done in a fertilizer blender. If it is ammonium sulfate liquid, urea, or UAN 32 (32% nitrogen as 50% urea and 50% ammonium nitrate), or other liquids containing nitrogen, it should be sprayed into the zeolite as it is blending.

  • Field blending of the zeolite with a nitrogen source may not be as efficient as blending in a fertilizer blender. Some of the nitrogen is leached through the soil rather than being exchanged in the zeolite.

  • Dry ammonium sulfate can be applied efficiently in a fertilizer blender by first dry blending the zeolite with the ammonium sulfate granules and then spraying in water. The water should amount to 10-15% by weight.

  • Typical applications for reclamation projects in nutrient-deficient soils have been in the range of 1.5 to 2.5 tons per acre of 3% amended zeolite.

  • Mid-summer fertilizing with amended BRZ™ zeolite in a nutrient deficient soil carried through the following year.
