Fluid Covering Implement for Rhizosphere Nutrient Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid dispensing systems for the rhizosphere of plants face significant nutrient loss due to volatilization, limiting the types of fluids that can be applied, particularly volatile substances that evaporate before absorption.
Innovation Solution
A fluid covering implement that moves soil from between rows of plants to cover applied fluids, using discs, plows, or knives to bring soil into contact with the rhizosphere, with adjustable depth guides and deflectors to regulate soil movement and prevent fluid loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If liquid dispensing systems apply fertilizer on the surface, then application efficiency is improved, but nutrient loss through volatilization increases
Solution Approach 1:
The patent applies preliminary action by positioning the soil mover to operate immediately after the liquid applicator deposits fertilizer on the soil surface. The soil is moved to cover the applied fertilizer before volatilization can occur, preventing nutrient loss while maintaining efficient application. This sequential operation ensures the fertilizer is covered in the critical time window between application and potential volatilization.
2Adaptability or versatility
If volatile fluids are applied to the rhizosphere, then application versatility is improved, but fluid loss through evaporation increases
Solution Approach 1:
The patent uses soil as an intermediary medium between the volatile fluid and the atmosphere. The soil mover positions soil to cover the applied volatile fluids in the rhizosphere, creating a physical barrier that prevents direct evaporation into the air. This allows versatile application of volatile substances like insecticides and herbicides while minimizing their loss through evaporation.
3Loss of substance
If soil is moved to cover applied fluids, then nutrient retention is improved, but device complexity increases
Solution Approach 1:
The patent merges the liquid application system and soil moving system into a single integrated implement. The soil mover is mounted on the same platform as the liquid applicator, with both components working in sequence during a single pass through the field. This combination reduces overall device complexity compared to using separate application and covering equipment, while maintaining effective nutrient retention through immediate soil coverage.
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
Effectively reduces fluid loss by covering applied substances with soil, allowing for the use of volatile fluids by bringing soil into contact with the rhizosphere, thereby enhancing nutrient retention and application efficiency.
Implementation Method 1
These liquid dispensing systems apply fertilizer on the surface, and on their own, they can be subject to significant nutrient loss through volatilization
