BRZ™ has two methods of holding cations such as ammonium, and plant nutrients. The first
 method is by absorption in channel ways. BRZ™ will hold up to 55% of its weight in water. The
 second method is by "cation exchange" (measured as cation exchange capacity or "CEC"). By
 this method, BRZ™ holds ammonium and other plant nutrients in the crystal structure where they
 are not water-soluble but are plant-accessible on an as-needed time-release basis.

• Mineral:          Consists of a volcanic mineral called "clinoptilolite” (see spec sheet)

• Size:               3/8” x ¼”. 4 x 8, 4 x 14, 14 x 40, 40 x 100, -100, -40 mesh

• GRAS:             Classified as “GRAS” (generally regarded as safe)
                          under21 CFR Part 582.2729

• Color:             Pale green when dry, dark green when wet

• Moisture:       Holds up to 55% of its weight in water

• Surface Area:            High surface area,  24.9 square meters/gram

• Weight:           55 pounds per cubic foot

• CEC:               High cation exchange capacity (CEC) of 150 to 180 meq/1000gram

•  Hydrophilic:

• Potassium:     3.47%

• Calcium:         1.6%

• Sodium:          <0.5% (no water soluble sodium)

·         CARRIER FOR PESTICIDES AND HERBICIDES

BRZ™ in a minus 40 or 100 mesh size or even finer is used as a carrier for pesticides and herbicides due to its porosity.

·         ODOR CONTROL

·         SOIL AMENDMENT

                                     See BRZ™ Soil Amendment.

·         FERTILIZER

BRZ™ can be ammoniated naturally with manure for the qualification of "organic grown" or artificially with ammonium nitrate, ammonium sulfate, urea, or other nitrogen sources. It
contains approximately 3.5% potassium. Phosphate can also be added.

·         WATER POLLUTION CONTROL

BRZ™ absorbs ammonium and ammonia gas to reduce the conversion of the nitrogen to
nitrates and nitrites that cause water pollution.
