First Milk UK: Soil Carbon Soars with Regenerative Farming
TL;DR: Dairy farms in the UK significantly increased soil carbon levels using regenerative practices like reduced tillage and cover cropping without compromising milk production.
- Regenerative practices boost soil carbon while maintaining dairy yields.
- Reduced tillage and diverse cover crops are key soil-building tools.
- Composted manure enhances microbial activity and soil health.
- Rotational grazing and mob stocking improve nutrient cycling.
- On-farm demonstrations overcome farmer skepticism and build networks.
Why it matters: Increasing soil carbon improves farm resilience, sequesters atmospheric carbon, and enhances biodiversity, offering significant environmental and economic benefits to farmers.
Do this next: Start a composting program with a 1:2 green to brown waste ratio, turning weekly, to produce stable soil amendments for your farm.
Recommended for: Dairy farmers seeking evidence-based methods to enhance soil carbon and farm resilience without sacrificing yield.
This report covers First Milk's regenerative farming trial in the UK, which achieved measurable increases in soil carbon through targeted soil management practices. The trial involved 20 farms implementing techniques such as reduced tillage, cover cropping, and composting to build soil organic matter while sustaining dairy productivity. Key methods included direct drilling to minimize disturbance, planting diverse cover crop mixes like rye, clover, and radish to maintain living roots year-round, and applying composted manure to boost microbial activity. Soil tests showed average carbon stock increases of 0.5-1.2 tons per hectare over two years, with some fields reaching 2 tons/ha, validated by lab analysis of 0-30cm depths. Practical guidance for farmers includes rotational grazing to enhance biodiversity, mob stocking for nutrient cycling, and hedgerow planting for erosion control. Results demonstrated no yield loss, with milk production stable or improved due to better soil structure and water-holding capacity. Expert insights from agronomists emphasize integrating livestock with cropping systems, using tools like soil moisture probes and carbon calculators for monitoring. The trial addressed barriers like farmer skepticism through on-farm demonstrations and peer learning networks. Composting protocols specified aerated static piles with green and brown waste ratios of 1:2, turned weekly for 8-12 weeks to produce stable amendments. This approach not only sequesters carbon equivalent to reducing herd emissions by 10-15% but also improves resilience to extreme weather. The piece offers concrete data tables on pre- and post-trial soil metrics, cost-benefit analyses showing ROI within 3 years, and scalable steps for other livestock operations, making it a valuable resource for practitioners seeking evidence-based regenerative strategies.
