Darren Doherty

Among the 1,500+ projects in Overyield today, the designs of Regrarians founder Darren Doherty stand out as illustrative examples of agro-ecological complexity, creative cross-platform utilization, and regenerative thinking.

Regrarians

Darren walked us through one of his largest projects to date: a 200 ha rain-fed vineyard block on a 20,000 ha regenerative farm in Kakheti, Georgia — the “cradle of winemaking,” where cinnamonic soils meet winter rainfall, and arid, sub-tropical, and continental climates collide to create an ideal terroir.

Darren’s design rationale followed the Regrarians methodological framework: He began by exploring Climate, moving next to Geography, Water, Access, Forestry, Buildings, and more. You may notice that some of these design pillars align with Overyield layers, speaking to the influence of Darren’s framework on the software.

Regenerative system design

Darren built out vineyard blocks that employ traditional key line geometry, as well as “straight key line geometry” based on the geography of the site, i.e. its contours, ridges and valleys. Darren remarked that straight keylines enable closer between-row spacing while facilitating ease of planting and machinery access for growers. Note that the vineyard rows pictured follow the “gradient of fall” towards ridges, optimizing rainfall distribution through improved surface and sub-surface water flow.

Ridges also inform the farm’s arterial road system, which he created using the line tool and include traditional paved roads (pink, above) and grassy access roads (yellow, below) that accommodate harvesting machinery.

Other regenerative practices employed include intra-row cover cropping, vernal ponds, and biodiverse shelterbelts, which follow the farm’s arterial roads and are laid out according to traditional windbreak guidance from Dr. Rod Bird of Queensland (e.g. their length equals 10x tree height to ensure adequate protection in the wind shadow.


Interoperability & Implementation

Excitingly, the project is currently in its deployment stage: ground prep is complete, with planting in December of 2023. Darren utilized Overyield during deployment, noting that our SHP exports were especially useful given their inclusion of boundary lines — a feature unique to Overyield — and compatibility with the Fendt 1159MT tractor from FJ Dynamics, enabling mechanical soil ripping using the AgriSoil Works deep ripper.
