Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current agricultural practices face challenges in optimizing nitrogen assimilation and use by plants, leading to inefficient fertilizer use and environmental pollution, with existing methods failing to maximize crop yield and quality without increasing fertilizer quantities.
Innovation Solution
A composition combining algae of the genus Laminaria and glutamic acid or its derivatives, applied in specific ratios, stimulates nitrogen metabolism by enhancing assimilation and translocation of nitrogen within plants, thereby improving crop yield and quality without increasing fertilizer amounts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If nitrogen fertilizers are intensively used to increase crop yield, then productivity increases, but environmental pollution worsens due to groundwater contamination, acid rain, and aquatic ecosystem destruction
Solution Approach 1:
The patent introduces a biostimulant composition containing algae extract and glutamic acid as an intermediary substance that mediates between the plant and nitrogen fertilizer. This composition enhances the plant's ability to assimilate and utilize nitrogen, allowing reduced fertilizer application while maintaining yield. The biostimulant acts as a bridge that improves nitrogen use efficiency, thereby reducing the harmful environmental effects of intensive fertilizer use.
Solution Approach 2:
The patent changes the physiological parameters of the plant by applying a biostimulant composition that modifies nitrogen metabolism. The algae extract and glutamic acid alter the plant's metabolic state, enhancing nitrate reduction, amino acid synthesis, and nitrogen translocation. This parameter change in the plant's physiological state allows more efficient use of nitrogen, reducing the need for high fertilizer doses and their associated environmental harms.
2Productivity
If nitrogen fertilizer quantity is increased to improve crop quality, then productivity increases, but loss of substance increases due to nitrate leaching and runoff
Solution Approach 1:
The biostimulant composition serves as an intermediary that improves the plant's nitrogen assimilation capacity. By enhancing the plant's metabolic enzymes and transport mechanisms, the composition ensures that more of the applied nitrogen is taken up and retained by the plant, reducing nitrate leaching and runoff while maintaining crop quality.
Solution Approach 2:
The biostimulant composition enables the plant to serve itself more efficiently in nitrogen utilization. By stimulating the plant's own metabolic pathways for nitrogen assimilation and distribution, the system reduces dependency on high external nitrogen inputs and minimizes nitrogen loss to the environment through leaching and runoff.
3Reliability
If conventional biostimulant compositions are used to enhance nitrogen assimilation, then nitrogen use efficiency improves, but the level of stimulation is insufficient to maximize crop yield without increasing fertilizer amounts
Solution Approach 1:
The patent merges two effective components - algae extract (providing natural biostimulants, amino acids, and growth factors) and glutamic acid (a key nitrogen metabolism intermediate) - into a single composition. This combination creates a synergistic effect that strongly stimulates nitrogen assimilation, nitrate reduction, and amino acid synthesis, enabling maximum crop yield achievement without increasing fertilizer amounts.
Solution Approach 2:
The biostimulant composition is a composite material combining extracts from Laminaria algae with synthetic or natural glutamic acid. This composite formulation integrates the benefits of natural seaweed extracts (rich in cytokinins, auxins, and amino acids) with the specific metabolic role of glutamic acid in nitrogen assimilation, creating a potent stimulant that maximizes nitrogen use efficiency and crop yield.
