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.

BENEFITS |
|
·
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. |
