About
Premium Peat-Free Compost Grown In Lincolnshire
Casswell’s Eco Green Compost was created to provide a better kind of peat-free compost – one that delivers dependable growing performance while actively regenerating the land used to produce it.
Founded by Lincolnshire farmer James Casswell, Eco Green Compost combines generations of agricultural knowledge with modern soil science and a carefully managed, closed-loop production process.
From our family farm at Orchard View, Fulstow Top (near Louth), we produce premium 100% peat-free compost and organic soil improvers for farmers, professional growers, landscapers, garden centres, and home gardeners throughout Lincolnshire and the UK.
From Lincolnshire Farmland
To Peat-Free Compost
The story began in 2020, when James recognised the growing demand for reliable alternatives to traditional peat-based compost.
At the time, many peat-free growing media struggled to provide the consistency, structure, and moisture retention required by professional growers. Drawing on his experience managing crops and soil, James set out to engineer a peat-free compost that would perform reliably without relying on council-collected green waste or synthetic fillers.
Today, the core ingredients used in our compost are grown, harvested, and processed on our Lincolnshire farm – giving us total control over quality, consistency, and supply chain traceability.
Two years of field trials, soil analysis, and process development followed before Eco Green Compost officially launched in 2022.
A Closed-Loop Approach to
Organic Compost Production
Our composting process begins in the field.
Through a carefully managed three-year crop rotation, we grow specialist cover crops selected to improve soil structure, naturally fix nitrogen, and capture carbon below ground. These crops are particularly valuable on resting or underperforming land, restoring soil health while producing nutrient-rich organic material.
During winter, local sheep graze the established crops, providing seasonal feed while naturally returning organic nutrients to the soil.
In spring, the upper growth is harvested and transferred to our dedicated composting pads. Beehives are positioned around the field margins, while pollen and nectar-rich wildflowers are drilled into the remaining cover to provide habitat for pollinators, wild birds, and local wildlife throughout the summer.
A final harvest is taken later in the season and blended with repurposed agricultural straw and wood-chipped wetland willow. Together, these carefully selected natural materials form the foundation of Eco Green Compost – delivering long-lasting moisture retention, organic nutrients, and a balanced growing environment.
