PROCESSED LASSENITE
Processed Lassenite Pozzolan is kiln fired or calcined at very high temperatures to produce a ceramic like textured particle that is resistant to breakdown. Lassenite is a naturally occurring material and contains no additives. Lassenite is extracted from a surface mine located in Lassen County, California. This deposit originated 26 million years ago when nearby volcanoes erupted and the volcanic ash was deposited into freshwater lakes. These freshwater lakes contained large amounts of protozoa called Diatoms. The skeleton of this tiny organism is extremely porous and adsorbent which allows for the efficient movement of water that adds to the permanent availability of water to turf and plants. This material is used primarily for topdressing after aeration or injection into the root zone and blended with sand and/or topsoil for new construction.Existing Turf/Sports Fields/Topdressing Golf Course
Fairways/Rough/Tee Boxes:
Application of 250 to 500 pounds per 1,000 square feet of turf
is recommended. Application can be performed by the use of a drop
spreader. Prior to application, the turf should be cut short and
thoroughly aerated (or aerated in two different directions). Utilize
drag-mats to increase the amount of Lassenite entering the soil
profile. Thoroughly water the turf to charge the Lassenite.
Injection/Drill and Fill:
Application of a minimum of 150 to 350 pounds per 1,000 square
feet is recommended when utilizing drill and fill or injection
equipment.
Trees/Shrubs/Container Plants:
Add a mixture of one part Lassenite to five parts potting soil.
New Construction or Renovation:
Apply at a rate of 5% to 10% by volume in the top 4 to 6 inches of the soil
profile. Rototill 1,000 to 2,000 lbs. of Lassenite per 1,000
square feet or pre-mix one pound of Lassenite for every 5 pounds of sand/soil
mix in the soil profile.
