Farmers Guardian Highlights Innovative Manure Management with Bokashi on Mixed Farm

The Farmers Guardian recently featured an insightful article on the innovative farming practices of James and Anna King, who are transforming traditional manure management with the use of Bokashi. This feature delves into how the Kings are revolutionising their farm operations by turning pig muck into nutrient-rich Bokashi, effectively improving their farm’s sustainability and productivity.

Spotlight on Sustainable Farming

The Kings' story is a testament to this commitment. The article, written by Jonathan Wheeler, explores how the Kings are integrating Bokashi with digestate from a local anaerobic digester as the main source of nutrition for their arable crops. The Kings farm 170 hectares (420 acres) near Buckingham, incorporating an additional 22 hectares (55 acres) of summer grazing.

Bokashi: A Traditional Technique with Modern Benefits

Bokashi, derived from the Japanese meaning "well-fermented organic matter," involves adding beneficial bacteria to manure and sealing it, allowing it to ferment like silage. This process retains virtually all the nutrients, unlike traditional composting which can lose up to 75% of nutrient value as gas or leachate. The article emphasizes how this method is a modern twist on traditional farming, ensuring maximum nutrient retention and minimal environmental impact.

Application Methods

The article describes the application methods for Bokashi, including using a knapsack sprayer, sprinklers, or misting systems. Our very own Andrew Sincock then explains that the treatment acts as a probiotic, helping animals' gut health and nutrient utilisation, which can enhance daily live-weight gains and help reduce antibiotic use and mortality risks. This highlights the practical benefits and versatility of Bokashi in modern farming.

A Nod to Traditional Farming

James and Anna’s approach, as detailed, is reminiscent of traditional mixed farming, where livestock and land benefited mutually from manure applications. The Kings' farm needs very little bagged nitrogen, showcasing the effectiveness of bokashi in reducing dependency on external fertilizers. The article underscores how this sustainable practice is both economically and environmentally advantageous.

Impact on Crop and Livestock Management

Highlighted are the Kings' efficient pig rearing system, where they raise five to six batches of pigs annually. The pigs are housed in open-fronted sheds with deep straw beds treated with Bokashi. This not only reduces odours—important for their adjacent holiday lets and caravan site—but also enriches the manure, making it a potent fertiliser for their crops.

Bokashi is used alongside digestate for their 80 hectares (200 acres) of arable crops. The article notes impressive yields: 50 tonnes per hectare (20t/acre) for maize and 10t/ha (4t/acre) for wheat in 2023, even during challenging conditions. This demonstrates the effectiveness of Bokashi in maintaining high productivity.

Future Prospects and Sustainability

Also explained is the long-term benefits of Bokashi. James believes it not only feeds the current crops but also improves soil productivity for future years. This aligns with the Kings' goal of a low-input farming system, minimizing chemical applications and ensuring soil health through regular sampling.

Conclusion

By integrating traditional methods with modern techniques, they are enhancing their farm’s productivity and sustainability, setting an example for farmers everywhere. This article is a testament to the evolving landscape of agriculture, where innovation and tradition work hand in hand for a better future.
