Angled Furrower Assembly for Soil Structure Preservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional agricultural practices lead to soil consolidation, restricting water and air movement, root growth, and crop production, especially in irrigated and high rainfall areas, resulting in reduced crop yields and increased water loss due to inefficient irrigation.
Innovation Solution
A furrower assembly with angled side plates and a flat base wider than tractor tires, designed to minimize soil compaction, promote lateral water infiltration, and maintain soil structure, allowing for one-pass bed loosening and seeding operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional cultivation inverts soil and tears out root systems, then soil is prepared for seeding, but soil stability decreases and consolidation increases rapidly
Solution Approach 1:
Instead of inverting the soil as in conventional cultivation, the furrower assembly maintains soil structure by creating furrows that preserve root systems and organic matter. The angled side plates and flat base design allow soil to be moved laterally without inversion, preventing the rapid consolidation that occurs with conventional plowing.
Solution Approach 2:
The furrower assembly creates localized furrow structures with specific geometric properties (angled side plates, flat base) that provide different soil conditions in different locations. The furrow walls maintain verticality to preserve soil structure, while the base width controls compaction zones, creating locally optimized conditions for root growth and water infiltration.
2Productivity
If tractor tires pass along furrows, then furrows are formed, but soil compaction increases especially in the bottom half of furrow walls
Solution Approach 1:
The furrower assembly creates the furrow structure before tractor passage. By pre-forming the furrow with angled side plates and a flat base that extends beyond the tractor tire width, the soil structure is established prior to compaction forces being applied, allowing the tractor to pass without causing excessive compaction in the critical furrow wall regions.
Solution Approach 2:
The furrow base width is designed to be greater than the tractor tire width, adding a dimensional buffer zone. This extends the protected area laterally beyond the compaction zone, creating a gradient where the furrow base provides structural support while the tire contact zone experiences controlled compaction that does not compromise overall furrow integrity.
3Quantity of substance
If furrows are formed with traditional designs, then water infiltration is limited, but irrigation time must be prolonged to ensure water penetration
Solution Approach 1:
The furrow structure is segmented into distinct functional zones: angled side plates that facilitate lateral water movement, a flat base that distributes water infiltration, and furrow walls that maintain structure. This segmentation creates multiple pathways for water infiltration, increasing the rate at which water penetrates to the root zone and reducing total irrigation time required.

AI summary
There is provided soil loosening and furrower assemblies and a bed renovator therefor. The soil loosening assembly comprises a blade assembly and wherein the blade assembly is horizontally pitched such that, when drawn beneath a soil surface at a fixed depth, the horizontally pitched blade assembly severs rootstock at the level of the blade assembly while retaining the rootstock substantially in place and loosens soil above the level of the blade assembly without substantial soil inversion. The furrower assembly comprises side plates extending rearwardly from a forward prow edge, wherein the side plates are approximately 25-45° with respect to the horizontal axis; and bottom edges of the side plates are approximately 20-40° with respect to a direction-of-travel axis.
