Abstract
A water-dispersible particle for delivery of nitrogen to a plant is disclosed. The water-dispersible particle also delivers an active ingredient such as a plant hormone to a desirable plant or a pesticide or herbicide to an undesirable organism. Methods for making and using the water-dispersible particle are described.
Claims38
A water-dispersible particle comprising:
- a methylene urea bioavailable to a targeted desirable organism present in an amount ranging from 5% to 99.9% by weight of the total dry weight of the particle;
- and
- a lignin derivative binder component, present in an amount ranging from 1% to 95% by weight of the total dry weight of the particle;
- the particle having a mean particle domain size;
- and
- the methylene urea and the lignin derivative binder component present in a form such that contact with water causes particle dispersion into more than 100 pieces.
3 more elements
A process for making a water-dispersible particle comprising the steps of:
- (a) mechanically aggregating into a pellet:
- a methylene urea bioavailable to a targeted desirable organism;
- and a lignin derivative binder component, present in an amount ranging from 1% to 95% by weight of the total dry weight of the particle;
- the nitrogen and the binder present in a form such that contact with water causes particle dispersion into more than 100 pieces;
- and
- (b) drying the pellet.
3 more elements
A process of nutrient delivery comprising the steps of:
- (a) administering a water-dispersible particle comprising:
- a methylene urea bioavailable to a targeted desirable organism present in an amount ranging from 5% to 99% by weight of the total dry weight of the particle;
- and a lignin derivative binder component, present in an amount ranging from 1% to 95% by weight of the total dry weight of the particle;
- present in a form such that contact with water causes particle dispersion into more than 100 pieces, the pieces releases the nitrogen containing ingredient to a target;
- and
- (b) allowing water to contact the particle.
