Row Unit Image Sensing for Seed and Residue Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural machines face challenges in uniformly planting seeds due to the impact of residue on soil quality, which affects thermal and moisture transfer, germination rates, and overall yield, as residue can inhibit soil warming, create physical barriers, and increase disease and insect presence.
Innovation Solution
A mobile agricultural machine equipped with a row unit featuring a furrow opener and closer, integrated with an image sensor system to sense residue and seed characteristics, generating control signals to adjust operations such as seed placement and residue management based on sensed data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If residue is left on the agricultural surface, then organic matter and nutrient cycling is maintained, but soil warming is inhibited and physical barriers are created that affect seed germination
Solution Approach 1:
The system applies different residue management strategies to different locations based on seed presence. Where seeds are detected, residue is removed or moved away to ensure good seed-to-soil contact and warming. Where no seeds are present, residue is left in place to maintain organic matter and nutrients. This localized approach resolves the contradiction between maintaining residue benefits and avoiding germination inhibition.
Solution Approach 2:
The sensor system detects seeds and residue characteristics before the furrow closer operates, allowing preliminary identification of areas where residue removal is necessary. This advance detection enables the system to prepare appropriate residue management actions, ensuring seeds are not placed in locations with excessive residue that would inhibit germination.
2Manufacturing precision
If residue is removed from the agricultural surface, then seed placement quality is improved, but organic matter and nutrient cycling are reduced
Solution Approach 1:
Rather than uniformly removing or retaining residue across the entire agricultural surface, the system selectively manages residue only in locations where seeds are detected. The sensor system identifies specific zones requiring residue removal for optimal seed placement, while leaving residue intact in other areas to preserve organic matter and support nutrient cycling.
Solution Approach 2:
The system uses onboard sensors to automatically detect seed and residue characteristics, eliminating the need for manual assessment. This self-service capability enables real-time, location-specific residue management decisions that optimize both seed placement quality and organic matter retention without human intervention.
3Productivity
If sensor systems are integrated to detect residue and seed characteristics, then planting operations can be optimized, but device complexity increases
Solution Approach 1:
The sensor system is designed to perform multiple functions: detecting seed presence, characterizing residue properties, and providing data for both immediate control decisions and historical analysis. This multi-functionality consolidates what could be multiple separate systems into a single integrated platform, managing complexity while maximizing productivity benefits.
Solution Approach 2:
The system implements feedback loops where sensor data about residue and seed characteristics is continuously monitored and used to adjust planting operations in real-time. This feedback mechanism enables automated optimization of planting parameters based on actual field conditions, improving productivity while the automated nature of the feedback reduces operational complexity.

AI summary
A mobile agricultural machine includes a row unit having a furrow opener mounted to the row unit and configured to engage a surface of ground to open a furrow in the ground. A furrow closer is mounted to the row unit behind the furrow opener relative to a direction of travel of the mobile agricultural machine and is configured to engage the surface of the ground to close the furrow. An image sensor system is mounted to the row unit and configured to sense characteristics of residue and seeds in the furrow opened by the furrow opener and generate a sensor signal indicative of the characteristics. The mobile agricultural machine can further include a control system configured to generate a residue/seed characteristic indicator corresponding to the sensed characteristics and to generate an action signal to control an action of the mobile agricultural machine based on the residue/seed characteristic indicator.
