For the construction of new golf course greens
and tees, lawns, gardens, or for sandy soils
replace 10 to 20 % of the sand with an equal
volume of BRZ™.. This should be applied in the
top 2 to 4 inches. For top dressing,
approximately 30 to 60 pounds should be applied
per 1,000 square feet or 1,200 to 2,500 pounds
per acre. To
enhance
aerification after plugging, apply 60 to 150
pounds per 1,000 square feet or 2,500 to 6,500
pounds per acre. For crops and grasses
successful improvements have been realized with
as little as 1 ton per acre. Generally, 2 to 10
tons per acre are applied depending on the
composition of the soil being treated. BRZ™ can
be spread by hand broadcasting, using a manure
spreader, or by other devices. Although top
dressing works, generally it is better to till
the BRZ™ in the top 2 to 4 inches with a
rototiller, spike tooth harrow, or a disc
harrow. Plowing BRZ™ in, places it deeper than
necessary. For row crops such as corn or
soybeans, BRZ™ can be applied with a side disc
or by side banding. After application the area
must be irrigated and fertilized, because fresh
BRZ™ will absorb moisture and nutrients from the
surrounding soil and can result in dehydration
and nutrient starvation of the plants or grasses
until an equilibrium has been reached.
-
It has a higher cation exchange capacity
for ammonium than any natural
clinoptilolite commercially available in
the western U.S. This quality favors
greater retention of ammonium (NH4+)
when the turf or soil is fertilized with
highly soluble ammonium-based
fertilizers.
-
This product contains approximately 85 ±
5% clinoptilolite which is a
concentration that is significantly
higher than any other high potassium,
low sodium, clinoptilolite that is
commercially produced in the U.S. This
accounts for the higher cation exchange
capacity of the product.
-
It has a high surface area (pore space)
of about 24.9 m2/gram (as measured
quantitatively by gas adsorption
-
This property allows a high capacity for
water retention inside the granules, and
also provides space for soil aeration.
The high capacity for water @ 55% will
aid in reducing water consumption in dry
climates.
-
When mixed with animal or poultry manure
this product provides a temporary
storage for ammonium and will reduce the
odor of the manures. Use of the product
on crops is consistent with the “Organic
Grown” USDA regulations for labeling
produce and field crops as “Organic
Grown” for marketing purposes.
-
The pale green color is attractive when
placed on turf grasses.
-
The low concentration of exchangeable
sodium avoids potentially plant toxic
sodium accumulation in soil.
-
Moderate physical strength and lack of
clay minerals and high pore space and
permeability provides a material which
promotes aeration in soil, whereas other
clinoptilolite with low physical
strength and layer silicates such as
clay minerals tend to pack and thereby
reduce aeration and also provide
physical barriers to water movement in
the soil.
-
This material has more
cation-exchangeable potassium than any
other commercially produced
clinoptilolite in the western U.S.
-
The low concentrations of potentially
toxic trace elements comply with State
and Federal regulations regarding the
amounts of these in materials contained
in fertilizer and soil amendment
products.
