Continuous Fertigation System for Micro-Irrigation Plugging Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Micro-irrigation systems are prone to plugging due to the sensitivity to water quality and additives, leading to uneven distribution of water and nutrients, and high labor and equipment costs in conventional fertigation methods.
Innovation Solution
A method of continuous fertigation where crop-quality-enhancer feedstock, including fertilizers, is charged to the irrigation system at low levels throughout the irrigation process, using an automated system to maintain a high-dilution environment and produce customized fertilizers with minimal nutrient-extraneous materials, reducing plugging and labor costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional fertigation methods are used to deliver fertilizers to crops, then fertilizer application efficiency is improved, but micro-irrigation systems become prone to plugging due to sensitivity to water quality and additives
Solution Approach 1:
The patent changes the concentration parameter of fertilizers by using highly soluble fertilizer materials and maintaining low concentrations in the irrigation water. This parameter change allows conventional fertigation methods to work effectively while preventing plugging, as the low concentration reduces precipitation and clogging of micro-irrigation systems
Solution Approach 2:
The patent applies different fertilizer concentrations to different locations in the irrigation system. Highly soluble fertilizer materials are applied at low concentrations in the main irrigation lines, while localized high-concentration applications are avoided. This local quality differentiation ensures system reliability while maintaining fertilizer application efficiency
2Productivity
If conventional fertigation methods are used, then fertilizer delivery is achieved, but labor and equipment costs increase
Solution Approach 1:
The patent employs automated injection systems that self-regulate fertilizer delivery based on irrigation water flow rates. The system automatically mixes and distributes fertilizers without requiring manual intervention for dosing calculations or application timing, thereby reducing labor costs while maintaining effective fertilizer delivery
Solution Approach 2:
The patent integrates fertilizer injection, mixing, and distribution functions into a single multi-functional fertigation system. This universal system handles both irrigation water delivery and fertilizer application simultaneously, eliminating the need for separate equipment and operations, thus reducing overall equipment costs and simplifying operations
3Quantity of substance
If high concentrations of fertilizers are applied, then nutrient delivery is improved, but plugging of micro-irrigation systems occurs
Solution Approach 1:
The patent fundamentally changes the concentration parameter by using highly soluble fertilizer materials at low concentrations in the irrigation water. This parameter change resolves the contradiction by delivering adequate nutrients through increased solubility and continuous low-level application rather than high-concentration pulses, thereby preventing plugging while maintaining nutrient delivery effectiveness
Solution Approach 2:
The patent implements continuous low-concentration fertilizer application throughout the irrigation process rather than intermittent high-concentration dosing. This continuous action ensures steady nutrient delivery to crops while maintaining low concentrations in the system that prevent precipitation and plugging of micro-irrigation components
4Reliability
If crop-quality-enhancer feedstock is charged continuously at low levels, then plugging issues are eliminated and labor costs are reduced, but automated systems and high-dilution environments are required
Solution Approach 1:
The automated injection system is designed to self-regulate based on irrigation water flow rates, automatically adjusting fertilizer dosing without requiring complex external control systems. The system monitors flow and self-adjusts injection rates, reducing the need for sophisticated automation while eliminating plugging through consistent low-concentration delivery
Solution Approach 2:
The patent changes the operational parameters of the irrigation system to maintain continuous high-dilution environments. By adjusting injection rates to match irrigation flow rates and maintaining low fertilizer concentrations throughout the system, the patent eliminates plugging while using relatively simple automated injection equipment rather than complex control systems

AI summary
An agricultural fertigation method includes the continuous charging of crop-quality-enhancer-feedstock comprised of one or more crop-quality enhancers (fertilizers, soil amendments and the like) to an irrigation system upstream of the agricultural field being irrigated. The crop-quality-enhancer-feedstock is diluted upon so charging to a level within the system solubility limits and the stream of flowing irrigation water dampens the resultant dissolution exotherm. A system wherein crop-quality enhancers are efficiently continuously fed to the irrigation system main line or a side-arm mixing chamber efficiently implements the method.
