Passive Soil Nutrient Profile for Deep-Layer Crop Feeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural practices rely heavily on surface fertilization and tilling to address nutrient depletion in the top three feet of soil, leading to high costs, environmental concerns, and inefficiencies.
Innovation Solution
A sustainable agriculture passive system comprising profiles and caps installed in the soil to access and passively supply nutrients deeper down, reducing the need for fertilizers and tilling by dispersing nutrients closer to the crop roots over time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If surface fertilization is used to address nutrient depletion, then crop nutrient supply is improved, but environmental pollution and production costs increase
Solution Approach 1:
The invention extracts nutrients from deep soil layers (below 2 feet) where they are normally inaccessible to plant roots, and delivers them directly to the root zone. This removes the need to apply fertilizers to the surface, thereby preventing the environmental pollution associated with surface fertilization while still providing adequate nutrient supply to crops
Solution Approach 2:
The patent introduces an intermediary device (the nutrient access system with profiles and caps) that mediates between deep soil nutrients and plant roots. This intermediary structure enables nutrient transfer from depths where nutrients naturally accumulate to the shallow root zone without requiring surface application, thus avoiding environmental harm
2Quantity of substance
If surface fertilization is applied to replenish nutrients, then crop growth is improved, but production costs increase
Solution Approach 1:
The system extracts previously inaccessible nutrients from deep soil layers and makes them available to crops, eliminating the need to purchase and apply expensive surface fertilizers. This reduces production costs while maintaining nutrient availability for crop growth
Solution Approach 2:
The invention enables the soil system to serve itself by allowing plant roots to access nutrients from deep soil layers through the installed profiles and caps. This self-service mechanism eliminates the need for external fertilizer inputs, thereby reducing production costs
3Stability of the object's composition
If crop rotation and tilling are performed to manage nutrient depletion, then soil fertility is maintained, but farming complexity and costs increase
Solution Approach 1:
The system extracts nutrients from deep soil layers and delivers them to the root zone, maintaining soil fertility without requiring complex crop rotation schedules or tilling operations. This simplifies farming operations while preserving soil health
4Quantity of substance
If deep soil nutrients are accessed, then fertilizer application is reduced, but system complexity increases
Solution Approach 1:
The invention segments the soil profile into accessible and inaccessible zones by installing profiles at specific depths with caps positioned in the root zone. This segmentation allows nutrients from deep layers to be accessed and delivered to plants, reducing fertilizer requirements while using a relatively simple segmented structure
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
Reduces the need for fertilizer application and tilling operations by passively supplying nutrients to crops, enhancing soil fertility and minimizing environmental impact over a period of 2 to 3 years.
Implementation Method 1
Diffusion involves the movement of the water nutrient solution from areas of higher concentration to areas of lower concentration to disperse the water nutrient solution in the soil and gradually move towards the root surface of the plants in the soil
Implementation Method 2
Mass flow involves the way the nutrients dissolved in the water within the soil are carried with the water as the water moves through the soil to be taken up by roots of the plants

AI summary
An agricultural nutrient supply device includes a profile and cap. The profile defines chambers that extends along a longitudinal axis of the profile from the first end to the second end of the profile. The cap engages with an end of the profile. The cap includes an exterior wall open at a first end and defining a dome at a second end of the cap. The exterior wall defines open channels that extend from the first end of the cap to a chamber defined by the dome. Several agricultural nutrient supply devices are configured to be installed in the soil of an agricultural farming field as a sustainable agriculture passive system. The system is installed in the agricultural farming field, the devices access nutrients deep in the soil and passively supply those nutrients to crops planted at the surface of the field thereby reducing required fertilizer or tilling.
