Compacted Fertilizer Granules for Uniform Micronutrient Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fertilizer compositions face challenges in ensuring uniform distribution and maximum availability of micronutrients to plant roots, as current methods like bulk blending and coating often result in segregation and inadequate soil solution introduction.
Innovation Solution
A compacted fertilizer composition is created by formulating a base fertilizer with primary nutrients, segregating and sizing granules, adding additional nutrients, crushing to increase reactive surface area, and compacting into granules that break down to ensure even distribution and maximum nutrient interaction with roots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If bulk blending with granular fertilizers is used to apply micronutrients, then application rates can be reduced and costs decreased, but segregation of nutrients occurs during blending and handling
Solution Approach 1:
The patent combines micronutrient granules with granular fertilizer in a bulk blending process to create a single mixed fertilizer product. This merging approach allows simultaneous application of both macro and micronutrients, improving manufacturing convenience and reducing separate application steps while maintaining uniform nutrient distribution through controlled blending parameters.
Solution Approach 2:
The patent applies local quality by ensuring that micronutrient granules are distributed uniformly throughout the bulk fertilizer mixture. By controlling the blending process to achieve homogeneous local distribution of micronutrients within the fertilizer matrix, the patent prevents segregation during handling while maintaining the convenience of bulk application.
2Stability of the object's composition
If micronutrient granules are made close to the same size as phosphate and potash granules to reduce segregation, then size segregation during handling is reduced, but micronutrient granules are too far from most plants to be of immediate benefit
Solution Approach 1:
The patent segments the fertilizer application function by creating a bulk blended mixture where micronutrient granules are distributed throughout the fertilizer matrix. This segmentation allows different granule sizes to coexist without segregation because they are embedded within the larger fertilizer structure, while still providing nutrients close to plant roots through the bulk application method.
Solution Approach 2:
The patent creates a universal fertilizer product that combines both macro and micronutrients in a single bulk-blended granular formulation. This multi-functional fertilizer simultaneously provides structural support through uniform granule size for easy handling and nutrient availability through integrated micronutrient distribution, eliminating the trade-off between stability and effectiveness.
3Stability of the object's composition
If coating onto granular fertilizers is used to apply micronutrients, then possibility of segregation is decreased, but binding materials do not maintain micronutrient coatings during bagging, storage, and handling
Solution Approach 1:
Instead of coating micronutrients onto granular fertilizer surfaces, the patent merges micronutrient granules directly into the bulk fertilizer mixture. This merging eliminates the coating adhesion problem entirely by integrating micronutrients as discrete granules within the fertilizer matrix, where they are held in place by the bulk structure rather than relying on binding materials that fail during storage and handling.
