GPS-Guided Apparatus for Targeted Urine Patch Detection and Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for reducing nitrogen leaching from pastures, such as using nitrate or urease inhibitors, are inefficient due to the difficulty in locating and treating individual urine patches, leading to excessive application over entire pasture areas and high labor requirements.
Innovation Solution
A self-operating, GPS-guided apparatus with rotatable metal discs that detect recent urine deposits by measuring conductivity changes, allowing for targeted application of nitrate inhibitors directly to affected areas, reducing the need for blanket coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If nitrate inhibitors are spread over entire pasture areas, then nitrogen leaching is reduced, but cost and labor increase significantly
Solution Approach 1:
The patent applies nitrate inhibitors locally only to urine-affected areas rather than blanket-spraying entire pastures. The detection system identifies specific locations where cows have urinated, and inhibitors are applied only to those targeted zones, reducing overall chemical usage and application costs while maintaining effectiveness in preventing nitrogen leaching.
Solution Approach 2:
The system uses automated detection and application mechanisms that reduce manual labor requirements. The detection system automatically identifies urine patches and triggers inhibitor application, minimizing the need for manual scouting and treatment of pasture areas.
2Difficulty of detecting and measuring
If chlorophyll detection is used to locate urine patches, then targeted treatment is enabled, but labor requirements remain high and detection may be too late
Solution Approach 1:
The patent replaces manual visual inspection and labor-intensive chlorophyll detection methods with automated sensor systems. The detection apparatus uses optical or other sensing technologies to automatically identify urine patches, eliminating the need for manual scouting and reducing labor requirements while enabling earlier detection before chlorophyll changes become visible.
3Ease of operation
If inhibitors are applied after urine deposition, then treatment is practical, but nitrogen conversion to nitrate has already begun reducing effectiveness
Solution Approach 1:
The system detects urine patches immediately after deposition occurs, before significant nitrogen conversion to nitrate takes place. By using sensitive detection methods that can identify fresh urine deposits, the system enables inhibitor application at the optimal time when treatment is most effective, preventing the rapid conversion of ammonium-N to nitrate-N that would reduce inhibitor efficacy.
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
This approach effectively identifies and treats urine patches within 48 hours of deposition, significantly reducing nitrogen leaching and gaseous emissions, while minimizing costs and labor, thereby improving pasture health and environmental sustainability.
Implementation Method 1
detect areas of the pasture which have had a (recent) deposition of urine by measuring a conductivity of the soil

AI summary
This invention relates to an apparatus for travelling over a ground surface, the apparatus including detection means for detecting an area of the ground surface (or sub-ground surface) which has had a deposition of excreta, and treatment means for treating the area with at least one substance. The apparatus may preferably be automated. In a preferred embodiment, the excreta being detected may be cattle urine and the substance(s) used to treat the area of deposition of urine may be a nitrate inhibitor and/or a urease inhibitor.
