This study evaluates the Royal Agricultural University (RAU) Zero-Dig initiative as a scalable and sustainable agricultural solution aligned with the UK's net-zero emission goals. Zero-dig farming, which avoids traditional ploughing, is assessed for its impacts on soil health, biodiversity, carbon sequestration, and economic feasibility. The method incorporates organic manure, companion planting, and greenhouse cultivation to enhance ecological resilience and reduce reliance on synthetic inputs.

A mixed-methods approach combined field observations from RAU’s experimental plots with qualitative analysis from stakeholder interviews. Key metrics included soil organic carbon levels, biodiversity indices, and input cost reductions.

Results indicate that zero-dig farming significantly improves soil structure, increases microbial activity, and enhances water retention. Soil samples from zero-dig plots showed higher organic carbon content than conventional tillage areas. Biodiversity, both above and below ground, was enriched through minimal soil disturbance and the integration of diverse plant species. Economically, while initial setup costs were substantial, covering greenhouses, irrigation, and composting infrastructure, the approach demonstrated long-term cost savings in synthetic inputs and labor. Market demand for organic produce further supports the financial viability of this method.

This study concludes that zero-dig farming presents a promising pathway toward sustainable agriculture. It offers tangible environmental and economic benefits, though barriers such as upfront investment and organic input logistics must be addressed. Educational outreach and community engagement have also proven crucial for adoption. The findings support broader implementation of zero-dig systems to achieve food security and environmental sustainability in temperate regions.
