A water-dispersible particle is provided that includes organic origin potash in an amount ranging from 5% to 99.9% by weight of the total dry weight of the particle. A binder component is present in an amount from 1% to 95% by weight. The organic origin potash and the binder component on that contact with water causes particle dispersion into more than 100 pieces.A process for making a water-dispersible particle includes mechanical aggregation of the potash into a pellet. A binder component is present in the particle in an amount ranging from 1% to 95% by weight. The potash and the binder component are present in a form such that contact with water causes particle dispersion into more than 100 pieces. The pellet is then dried and ready to be applied.
