Abstract
A water-dispersible particle for delivery of fertilizer to a plant is disclosed. After delivery wetting of the particles causes particle dispersion so as to prevent secondary pick up to the particles. Methods for making and using the water-dispersible particle are described.
Claims24
A water-dispersible particle comprising:
- a fertilizer bioavailabie to a targeted organism present in an amount ranging from 5% to 99% by weight of the total dry weight of the particle, the fertilizer having a mean aggregate domain size of less than 500 micrometers, and comprising one or more of isobutylidene diurea, ammonium aniline, diammonium phosphate, mono-ammonium phosphate, dicyandiamide, or metal ammonium phosphates;
- a lignin derivative binder component, present in an amount ranging from 1% to 95% by weight of the total dry weight of the particle, said lignin derivative intermixed with said fertilizer fines throughout said particle;
- the particle having a mean particle domain size;
- said particle having a moisture content of less than 0.5% throughout;
- and
- the fertilizer and the lignin derivative binder component present in a form such that contact with water causes particle dispersion into more than 100 pieces.

A water-dispersible particle comprising:
- a fertilizer having a mean aggregate domain size of less than 500 micrometers, and comprising isobutylidene diurea and potassium sulfate;
- and
- a lignosulfonate derivative binder component, present in an amount ranging from 1% to 95% by weight of the total dry weight of the particle;
- said lignosulfonate derivative intermixed with said fertilizer fines throughout said particle;
- the particle having a mean particle domain size;
- said particle having a moisture content of less than 0.5% throughout;
- wherein the fertilizer and the lignin derivative binder component are present in a form such that contact with water causes particle dispersion into more than 100 pieces.
