Flotation is a simple method of collecting and submerging (under water) arthropods from various substrates, including beetles and fly pupae from manure, but not all organisms are collected easily.Flotation is deemed laborious because of the difficulty in collecting the substrate and/or separating organisms from floated debris.
Flotation is the ability of an object to remain on top of a surface.Optimum flotation is going to be very dependent on soil types and soil conditions.If you’re in sloppy, thin mud, wide tires can provide plenty of flotation to keep you on the surface, but that slick soil will offer very little traction.
