Dispersible sulphur fertilizer pellets
Abstract:
A water dispersible pellet and method of producing same comprising: micronized elemental sulphur with 80% of particles less than 30 microns, a binder component in the amount ranging from 0.95% to 95% by weight; a surfactant in the amount ranging from 0.05% to 10% by weight; a soluble salt present in the amount ranging from 0.05% to 95% by weight; bentonite clay in the amount ranging from 0.05% to 95% by weight. The pellet having a mean particle domain size and a mean crushing strength, all in a form such that within a few minutes of contact with water the pellet disperses into particles with more than 10% of said particles passing through a 50 mesh (US Standard Size) screen.
