Managing horse manure is one of the biggest challenges for equine facilities. Traditional composting methods, such as windrows, can take months, require large land areas, and often result in inconsistent product quality. But what if you could transform stall waste into a nutrient-rich biofertilizer in just 5–8 days?

At HiPoint AG, we utilize a state-of-the-art bioreactor composting system that revolutionizes the processing of horse manure. Running our patented system, we first separate all the wood shavings, a key to success. Then, through accelerating microbial activity, the technology delivers fast, clean, and sustainable results.

The Problem with Traditional Composting

Horse manure mixed with wood shavings is notoriously slow to break down. In composting scenarios, lignin-rich wood shavings resist breakdown due to their biological armour leading to slow composting, leading to leaching and off-gassing

Lignin is a complex, cross-linked polymer found in the cell walls of plants, especially in wood and bark. It acts like a biological armour, giving plants rigidity and resistance to microbial attack.

Windrow composting can take a minimum of 12 weeks to 6 months, requiring constant turning, moisture control, and space. The high carbon content of wood shavings skews the carbon-to-nitrogen (C: N) ratio, slowing microbial decomposition and producing uneven compost.

Beyond the time and labour, traditional composting poses environmental risks:

• Methane emissions (EPA AgSTAR Program)
• Odour and runoff
• Inconsistent nutrient profiles

For equine operations focused on sustainability and efficiency, this method is no longer viable.

Why Horse Manure is a Powerful Biofertilizer

When properly processed, horse manure is a nutrient-rich organic fertilizer. It contains:

• Nitrogen – essential for plant growth
• Phosphorus – supports root development
• Potassium – improves drought resistance and overall plant health

Once wood shavings are removed, the manure becomes an ideal input for composting. It decomposes more quickly, produces less odour, and yields a microbially active biofertilizer that enhances soil health and fertility. (University of Minnesota Extension)

The Role of Wood Shavings—and Why Separation Matters

Wood shavings are valuable for stall bedding but problematic in compost. Their high carbon content slows decomposition and absorbs moisture, making it harder to maintain optimal composting conditions. (USDA NRCS)

HiPoint AG’s system separates wood shavings from manure, allowing:

• Reuse of clean shavings for bedding
• Faster composting of manure in the bioreactor
• Improved nutrient concentration in the final product

This separation is key to unlocking the full potential of horse manure as a biofertilizer.

Enhancing Biofertilizer with Rock Phosphate, Sulphate of Potash, and Biochar

To further improve the nutrient profile and soil-enhancing properties of our biofertilizer, HiPoint AG incorporates Rock Phosphate, Sulphate of Potash, and Biochar into select blends. Rock Phosphate adds long-lasting phosphorus for root development, Sulphate of Potash boosts potassium for plant resilience, and Biochar improves soil structure, water retention, and microbial activity. These additives work synergistically with the composted manure to create a balanced, slow-release fertilizer that supports healthy crop growth and soil regeneration.

HiPoint AG and Bioreactor Technology: Compost in Days, Not Months

Our bioreactor system uses controlled temperature, aeration, and microbial acceleration to process manure in just 5–8 days. Unlike traditional methods, the bioreactor:

• Maintains ideal conditions for microbial activity
• Eliminates the need for manual turning
• Produces a consistent, high-quality biofertilizer

This technology is scalable for large equine operations, making it easy to manage stall waste while creating a valuable agricultural product. (Journal of Environmental Management)

Environmental and Economic Benefits

Switching to HiPoint AG’s bioreactor system offers both environmental and financial advantages:

• Reduces landfill waste and hauling costs
• Minimizes greenhouse gas emissions (EPA AgSTAR Program)
• Creates a marketable product from waste
• Supports circular agriculture and carbon-smart farming

Facilities can turn a liability into an asset—reducing costs while contributing to sustainable agriculture.

Custom Blends for Specific Agricultural Needs

Thanks to our rapid 5–8 day production cycle and precise control over input ratios, HiPoint AG can create custom biofertilizer blends tailored to the needs of different customers. Whether a farm requires higher nitrogen for leafy greens, more potassium for fruiting crops, or enhanced microbial content for soil restoration, our system allows for flexible formulation. This adaptability makes our solution ideal for organic growers, landscapers, pasture managers, and anyone seeking a targeted, sustainable fertilizer solution. (Food and Ag Org of the UN)

Brewing Biological Tea: A Natural Boost for Your Fields

Once the composted fertilizer has completed its bioreactor transformation, we can take one further optional step when a customer wants which is to extract its biological power into a liquid form—commonly referred to as a “biological tea.”

But why the name?

Much like steeping herbs in a teabag, we place the finished compost into a porous sack, resembling an oversized tea bag. This sack is submerged in water and left to steep for several hours or days, depending on the desired potency. During this process, beneficial microbes, soluble nutrients, and organic compounds leach into the water, creating a rich, biologically active liquid.

This “tea” can then be sprayed directly onto fields, delivering nutrients and microbial life in a form that’s easy to apply and quickly absorbed by soil and plants.

It’s a simple, scalable method to activate the biology of your compost and extend its benefits beyond the pile—turning waste into wellness for your crops.
