Polyamino Acid Composition Enhances Plant Nutrient Uptake
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fertilizers have low absorption rates by plants, leading to economic losses and soil quality issues, with phosphate fertilizers being particularly inefficient, as less than 15% is absorbed, and unabsorbed fertilizers can cause undesirable soil changes.
Innovation Solution
A composition containing poly amino acids or their derivatives, citric acid, and L-amino acids, which can be applied directly to plants or mixed with fertilizers, enhances nutrient uptake by slowing down nitrogen conversion and maintaining phosphate in an available state, reducing leaching and improving root growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional fertilizers are applied to promote plant growth, then plant yield is improved, but fertilizer absorption efficiency deteriorates (less than 50% absorption, as little as 15% for phosphate)
Solution Approach 1:
The patent introduces polyamino acids as intermediary substances that mediate between fertilizer and plant roots. These polyamino acids form complexes with phosphate and other nutrients, preventing fixation and enhancing solubility, thereby improving plant uptake efficiency while reducing waste
Solution Approach 2:
The invention creates composite fertilizer formulations by combining conventional fertilizers with polyamino acids. This composite approach allows the synergistic interaction between the fertilizer components and polyamino acids, enhancing nutrient availability and plant absorption while reducing overall fertilizer requirements
2Quantity of substance
If phosphate fertilizer is applied to improve plant growth, then phosphate availability is improved, but soil quality deteriorates due to phosphate fixation and unabsorbed fertilizer accumulation
Solution Approach 1:
Polyamino acids act as intermediary agents that bind to phosphate ions, preventing their fixation by soil minerals. This intermediary complexation keeps phosphate in a soluble, plant-available form without allowing it to accumulate as fixed, unavailable residues in the soil
Solution Approach 2:
The invention changes the chemical parameters of phosphate in soil by introducing polyamino acids that alter its solubility and reactivity characteristics. This parameter change prevents phosphate from undergoing harmful fixation reactions while maintaining its nutritional availability
3Quantity of substance
If nitrogen fertilizer is applied to enhance plant growth, then nitrogen supply is improved, but nitrogen loss through leaching and conversion deteriorates efficiency
Solution Approach 1:
Polyamino acids serve as intermediary substances that form complexes with nitrogen, slowing its conversion rates and reducing leaching. This intermediary binding allows for more controlled nitrogen release and uptake by plants, minimizing losses to the environment
