Choosing An Appropriate Substance
1. Quality and Characteristics
It is very important to choose a high-quality topdressing substrate. For greatest cost efficiency,
Ecolawn recommends using a bulk substrate which is friable, has a moisture content lower than 65%, and
contains no inorganic matter (stone, plastic, glass, etc.) or non-composed organic matter (such as wood
pieces).
2. Friability
A friable material is one that crumbles easily into small fragments. A substrate that is not very friable
appears to be composed of numerous, compact pieces which do not readily break down. Screening a
substrate makes it much more friable. Additionally, a substrate containing 10% sand is more friable and will
flow more smoothly and efficiently through the applicator.
3. Moisture Content
To help the substrate flow freely from the hopper, you may lightly bounce the spreader by moving it up and
down while topdressing. This will loosen the substrate so that it can flow freely from the hopper.
A substrate with a moisture content greater than 65% will tend to stick to the inside walls of the hopper and
other parts of the spreader. When working with a substrate with a high moisture content, coat the insides of
the hopper, as well as the spreading disk, with a graphite-based lubricant. Consult the SLIP Plate Lubricant
