Solution Overview

Problem

Current biofertilizer formulations for nitrogen fixation in organic and sustainable farming often rely on single nitrogen-fixing sources and lack efficient nutrient use, leading to soil degradation and imbalanced nutrient availability, while also requiring chemical fertilizers, which are environmentally harmful.

Innovation Solution

A Bio-Nitrogen fertilizer formulation containing a combination of nitrogen-fixing microorganisms such as Azotobacter sp., Azospirillum sp., Rhizobium sp., and Gluconacetobater diazotrophicus, along with nitrogen-rich carrier materials, bentonite, and essential minerals, in liquid, powder, or granular form, to enhance nitrogen bioavailability and reduce chemical fertilizer use.

1Productivity

If chemical nitrogenous fertilizers are applied to meet crop nitrogen demand, then crop productivity is improved, but soil degradation, nutrient imbalance, and environmental pollution occur

Engineering Contradiction:

Improvecrop productivityVSAvoidsoil degradation and environmental pollution

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent combines multiple nitrogen-fixing microorganisms (Azotobacter, Azospirillum, Rhizobium, and Gluconacetobacter diazotrophicus) into a single biofertilizer formulation. This merging of different nitrogen fixation mechanisms provides diverse nitrogen sources while reducing chemical fertilizer dependency, thereby improving crop productivity without causing soil degradation and environmental pollution

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent changes the nitrogen source parameter from chemical inorganic nitrogen to biological nitrogen fixation through multiple microorganism strains. This parameter change transforms the harmful chemical fertilizer application into a beneficial biological process, maintaining crop productivity while eliminating soil acidification, nutrient imbalance, and environmental pollution

Inventive Principle:

Principle #35Parameter changes

2Device complexity

If single-source biofertilizer formulations are used for nitrogen fixation, then formulation simplicity is maintained, but nitrogen fixation efficiency and nutrient use efficiency are insufficient

Engineering Contradiction:

Improveformulation simplicityVSAvoidnitrogen fixation efficiency

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The patent creates a composite biofertilizer formulation containing four different nitrogen-fixing microorganism strains along with carrier materials and nutrients. This composite approach integrates multiple biological functions into a single formulation, significantly enhancing nitrogen fixation efficiency and nutrient use efficiency while maintaining practical formulation simplicity for agricultural application

Inventive Principle:

Principle #40Composite materials

3Stability of the object's composition

If chemical fertilizers are used to maintain soil fertility, then crop growth is supported, but long-term application causes soil acidification and nutrient depletion

Engineering Contradiction:

Improvesoil fertilityVSAvoidsoil acidification and nutrient depletion

Core Design Contradiction:

Stability of the object's compositionVSObject-generated harmful factors

Solution Approach 1:

The patent employs nitrogen-fixing microorganisms that enable the soil system to generate its own nitrogen through biological fixation. This self-service mechanism reduces external chemical inputs, prevents soil acidification from ammonia-based fertilizers, and maintains soil fertility through natural nutrient cycling and microorganism-mediated nutrient availability

Inventive Principle:

Principle #25Self-service
