Water-Dispersible Seed Meal Particles for Uniform Nutrient Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing granular products used for delivering plant nutrients, pesticides, and pest irritants remain in solid or semisolid form for extended periods, leading to reduced efficacy, loss through volatilization and photodegradation, and increased risk of skin irritation and toxicity, while also being difficult to uniformly disperse on target surfaces.
Innovation Solution
Development of water-dispersible granulated seed meal particles with a binder component that break into numerous smaller pieces upon contact with water, allowing for controlled release and uniform distribution of additive agents, including biochar, microbes, and nutrients, effectively repelling round worms and aiding bioremediation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If granular products are applied to deliver plant nutrients and pesticides, then large areas can be covered with minimal distance traversed, but the products remain in solid or semisolid form for several days causing reduced efficacy and loss through volatilization
Solution Approach 1:
The granular product is segmented into smaller particles with sizes ranging from about 0.03 millimeter to about 0.3 millimeter. This segmentation increases the surface area to volume ratio, allowing the additive ingredients to be released more quickly and uniformly, thereby reducing losses through volatilization and photodegradation while maintaining the ability to cover large areas efficiently
Solution Approach 2:
The particle size parameter is changed from the conventional 0.3-10 millimeter range to a smaller 0.03-0.3 millimeter range. This parameter change fundamentally alters the dissolution and release characteristics of the granular product, enabling faster dispersion and reduced persistence on the surface, thus minimizing ingredient loss
2Reliability
If granular products remain in solid or semisolid form for long periods, then the additive ingredients are physically bound up reducing efficacy, but changing the product form may affect delivery uniformity
Solution Approach 1:
By segmenting the granular product into finer particles (0.03-0.3 mm), the product maintains better flow characteristics and uniformity during broadcast application while simultaneously enabling faster dissolution and release of additive ingredients, thus improving efficacy without sacrificing application uniformity
Solution Approach 2:
The product is designed to transition dynamically from a stable granular form during application to a rapidly dispersing form after application. The fine granular structure remains intact during broadcasting but quickly breaks down and dissolves upon contact with moisture, providing both uniform delivery and rapid efficacy
3Manufacturing precision
If granular products are applied to sloping ground with low percolation rates, then the products may be removed by run-off causing loss of uniformity, but increasing particle size may improve delivery uniformity
Solution Approach 1:
The fine granular size (0.03-0.3 mm) allows the product to penetrate into the soil more effectively rather than sitting on the surface where it would be susceptible to run-off. The smaller particles can move with water infiltration, reducing loss through surface run-off on sloping ground while maintaining uniform distribution
Solution Approach 2:
The product leverages hydraulic action through water infiltration to move the fine granular particles into the soil profile. The small particle size enables effective movement with minimal water, allowing the product to be incorporated into the soil on sloping ground without requiring large quantities of water, thus preventing run-off loss
4Object-affected harmful factors
If granular products persist on the surface, then the likelihood of physical contact with people and animals increases causing skin irritation and toxicity, but reducing particle size may affect spreadability
Solution Approach 1:
The fine granular size (0.03-0.3 mm) reduces the physical contact hazard by enabling faster incorporation into the soil or substrate, minimizing the time particles remain on the surface where they could contact skin. The segmented structure also improves airflow through the material, enhancing spreadability from mechanical spreaders despite the smaller size
5Ease of operation
If previous attempts to spread granulated seed powders are made, then the seed powder tends to clump and not uniformly disperse from mechanical spreader, but using larger extruded pellets requires large quantities of water to disperse
Solution Approach 1:
The optimal fine granular size range (0.03-0.3 mm) prevents clumping during mechanical spreading while enabling rapid dispersion with minimal water application. This segmented size provides the ideal balance between maintaining flowability for uniform distribution and enabling quick breakdown upon water contact, eliminating the need for large quantities of water required by larger pellets

AI summary
A water-dispersible particle is provided to disperse additive agents and substances that repel specific species such as round worms or fish, function in bioremediation, or a combination thereof. The dispersible particles are used to treat soil or bodies of water. Exemplary uses include turf management, soil reclamation, and aquaculture. A water-dispersible particle for delivery of granulated seed meal is provided. In exemplary form, granulated camellia seed is delivered in the form of dispersible particles. A method for making and using the water-dispersible particle is also provided. The durable particle retains size and shape during handling and application to a desired area and dissolves or crumbles into small particles upon contact with water or a water overspray within twelve hours thereby facilitating controlled release and distribution of the additive agents and substances to the target including granulated seeds, nitrogen, and optional agents including plant nutrients, pesticides, hormones, herbicides, and micronutrients.
