Liquid Fertilizer with Nano-bubbles for Nutrient Uptake
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid fertilizers do not effectively enhance plant growth and optimize soil conditions for efficient nutrient uptake and microbial activity, leading to suboptimal crop yields.
Innovation Solution
A liquid fertilizer composition with nano-bubbles, specifically molecular oxygen and other gases with diameters less than 500 nanometers, is dispersed throughout the fertilizer to enhance plant growth by improving nutrient metabolism, microbial activity, and soil conditions, while maintaining stability and shelf life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional liquid fertilizers are used, then basic nutrient supply is provided, but plant growth enhancement and nutrient uptake efficiency are insufficient
Solution Approach 1:
The patent introduces nano-bubbles with specific size parameters (less than 500 nanometers in diameter) into the liquid fertilizer composition. This parameter change in bubble size creates neutral buoyancy and extended suspension stability, allowing the fertilizer to remain effective longer and be more reliably taken up by plant roots, thereby improving both productivity and nutrient uptake efficiency
Solution Approach 2:
The patent creates a composite liquid fertilizer composition by combining conventional liquid fertilizer with dispersed nano-bubbles. This composite structure integrates the nutrient-providing function of the liquid fertilizer with the oxygen-delivery and suspension-stabilizing functions of the nano-bubbles, resulting in enhanced plant growth and more reliable nutrient uptake
2Quantity of substance
If liquid fertilizer is applied to soil, then nutrients are supplied to plants, but oxygen supply and microbial activity are insufficient
Solution Approach 1:
The nano-bubbles in the liquid fertilizer composition serve multiple functions simultaneously: they deliver oxygen to the soil and plant roots, maintain suspension stability of the fertilizer components, and provide energy for microbial activity. This multi-functionality allows the same composition to satisfy both nutrient supply requirements and microbial energy needs without requiring separate applications
3Quantity of substance
If fertilizer particles are suspended in liquid carrier, then nutrient delivery is improved, but viscosity increases and handling becomes difficult
Solution Approach 1:
The patent changes the physical parameter of the liquid carrier by introducing nano-bubbles, which reduce the overall viscosity of the suspension. The nano-bubbles create a frothy, aerated structure that decreases density and improves flow characteristics, making the high-nutrient-density fertilizer easier to pump, spray, and handle while maintaining concentrated nutrient delivery
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The nano-bubble dispersion increases the efficacy and efficiency of liquid fertilizers, leading to higher crop yields, improved plant vigor, and enhanced nutrient uptake, with noticeable improvements in corn, cotton, sugarcane, and turf grass trials.
Implementation Method 1
nano-bubbles are dispersed throughout the liquid fertilizer
Implementation Method 2
The nano-bubbles are neutrally buoyant and can therefore remain suspended in the liquid fertilizer for an extended period of time

AI summary
Liquid fertilizer compositions and methods of making and using the compositions for fertilizing crops are provided. A liquid fertilizer formulated to enhance plant growth is infused with nano-bubbles that increase the efficacy of the liquid fertilizer. The liquid fertilizer is mixed and homogenized before flowing the liquid fertilizer through a nano-bubble generator. The liquid fertilizing composition infused with nano-bubbles may be applied to soil in the same manner as standard liquid fertilizers to further promote plant growth.
