Bio Agricultural Developments
Bio Agricultural Developments has pioneered a breakthrough in sustainable agriculture with the launch of ‘BLACK GOLD’, a 100% organic fertiliser designed to revolutionise the way farmers, groundskeepers, and agribusinesses approach crop, turf, and pasture management. Recognising the growing need for agricultural solutions that balance modern efficiency with environmental responsibility, BLACK GOLD is positioned as a game-changer in sustainable fertilisation practices.
Who is Black Gold for?
100% Organic Fertiliser Certified by the Irish Department of Agriculture
BLACK GOLD is a P9 Seaweed Fertiliser range which is produced locally and accredited by the Irish Department of Agriculture, Food and Marine, guaranteeing compliance with the highest standards of quality and safety. Unlike conventional chemical fertilisers, which may deplete soil nutrients and harm ecosystems over time, BLACK GOLD leverages natural, organic ingredients that promote long-term soil health, microbial activity, and nutrient retention.
This certification reassures agricultural professionals that the product is fully compliant with national regulations, making it suitable for both conventional farms transitioning to sustainable practices and fully organic operations seeking enhanced productivity.

Reviews
“Transformed Our Farm Completely”
We started using BLACK GOLD last spring, and the results have been outstanding. Our pastures are greener, denser, and far more nutritious for the herd. The cows are producing better-quality milk, and the soil has improved dramatically. It’s a relief to know we’re using a 100% organic fertiliser accredited by the Department of Agriculture. We’ll never go back to traditional chemical options again.

What Is P9 Fertiliser?
P9 fertiliser is an advanced agricultural solution designed to deliver unparalleled results for soil health and plant growth. This unique formulation combines essential bacteria, enzymes, and natural seaweed hormones to create a powerful all-in-one fertiliser that requires no additional additives. Unlike conventional fertilisers that depend on multiple supplementary products, P9 fertiliser provides a complete and self-sustaining nutrient system that enhances both soil biology and plant vitality.
The “P9” name refers to the proprietary blend of beneficial microorganisms and enzymes included in the formulation. These microbial strains work synergistically to improve soil fertility, boost root strength, and increase crop yield. By promoting biological activity within the soil, the P9 formula creates an environment where plants can absorb nutrients more effectively and resist stress factors such as drought, disease, and poor soil structure.
Core Bacterial Components of P9 Fertiliser
The effectiveness of P9 fertiliser lies in its scientifically selected bacterial and fungal components. Each strain serves a specific function in promoting sustainable plant growth and soil regeneration:
Bacillus subtilis – Enhances nutrient uptake and improves root development through natural growth-promoting hormones.
Bacillus cereus – Aids in the breakdown of organic matter, increasing soil fertility and nutrient availability.
Bacillus licheniformis – Produces enzymes that help release bound nutrients, particularly phosphorus and nitrogen.
Bacillus thuringiensis – Acts as a natural pest control agent, protecting crops from harmful insects without chemicals.
Bacillus amyloliquefaciens – Stimulates root growth and strengthens plant resistance to pathogens.
Trichoderma reesei – Known for its powerful enzyme production, helping decompose organic residues and improve soil aeration.
Trichoderma harzianum – Promotes root health and acts as a biocontrol agent against soil-borne diseases.
Paecilomyces lilacinus – Naturally suppresses nematodes and improves soil microbial diversity.
Penicillium bilaiae – Mobilises phosphorus in the soil, ensuring plants can access this critical nutrient efficiently.Together, these microorganisms form a biologically active fertiliser that not only feeds plants but also rejuvenates the soil ecosystem for long-term sustainability.

Why Choose P9 Fertiliser?
The P9 formulation stands apart due to its balance of biological, enzymatic, and hormonal components. Where many fertilisers rely on synthetic chemicals, P9 uses natural processes to foster healthy plant development. Some of its most notable benefits include:
Enhanced nutrient absorption through microbial action.
Improved root establishment and plant vigour.
Increased resistance to drought and disease.
Reduced dependence on chemical additives or synthetic fertilisers.
Sustainable soil health for future planting cycles.
For professional growers, landscapers, and hobby gardeners alike, P9 fertiliser represents a breakthrough in natural plant nutrition. It supports everything from large-scale agriculture to home gardens, offering measurable results across diverse environments.

Who Can Use Black Gold Fertiliser?
Black Gold fertiliser is a versatile product designed for anyone who grows or maintains plant life. Its comprehensive formulation ensures that both professionals and hobbyists can achieve superior growth, improved soil structure, and enhanced environmental resilience.
Here are the key groups who benefit most from Black Gold fertiliser:
1. Farmers
Farmers across a range of agricultural sectors can use Black Gold to promote stronger crop yields, improve soil fertility, and minimise the need for synthetic fertilisers. Its unique blend supports consistent growth cycles and healthier harvests by balancing nutrients and stimulating beneficial soil microbes.
2. Golf Course and Sporting Ground Superintendents
Maintaining lush, green, and resilient turf is essential for sports grounds. Black Gold fertiliser enhances turf density, improves root systems, and increases recovery from heavy foot traffic. It helps golf courses, football pitches, and other sporting facilities maintain visually appealing and durable grass throughout the year.
3. Nurseries and Garden Centres
Nurseries benefit from Black Gold fertiliser because it encourages rapid and healthy plant development from the seedling stage through to maturity. It creates uniform growth across a wide range of plants, ensuring higher quality products for sale and reducing plant loss due to nutrient stress.
4. Gardeners and Landscapers
Home gardeners and professional landscapers can use Black Gold to revitalise lawns, vegetable beds, ornamental gardens, and flower borders. Its organic composition means it is safe for long-term soil use and supports eco-friendly gardening practices without harmful chemicals.

Where Can Black Gold Fertiliser Be Used?
Black Gold fertiliser can be applied almost anywhere plants grow. Its flexibility and biological composition make it suitable for both small-scale and commercial applications. Below are some of the most common environments where Black Gold excels:
1. Agricultural Land
From arable fields to mixed farming operations, Black Gold ensures that soils remain productive and fertile. Its microbial activity improves soil structure and water retention, while its enzymatic components unlock essential nutrients needed for strong crop development.
2. Golf Courses and Sports Grounds
Sports turf requires precise nutrient balance to withstand constant wear and tear. Black Gold fertiliser restores soil vitality, enhances turf colour, and promotes deeper roots — leading to stronger and more resilient grass across greens, fairways, and pitches.
3. GAA Clubs and Rugby Fields
Irish sporting clubs, including GAA pitches and rugby fields, rely on consistent grass quality. By integrating Black Gold fertiliser into their turf maintenance programmes, groundskeepers can achieve faster recovery after matches, greater grass density, and a visibly healthier playing surface.
4. Home Gardens and Allotments
For home growers, Black Gold transforms tired or depleted soil into a fertile foundation for vegetables, flowers, and shrubs. It improves nutrient cycling and enhances soil life, ensuring plants thrive season after season.
