Horse Manure Disposal: Turning a Liability into an Asset

Horse Manure Disposal: Turning a Liability into an Asset

Did you know that horse manure is not waste but a valuable resource? What makes horse manure more than waste? Read on to find out.

While nothing can be more exciting than owning a horse, this joy comes with certain practical challenges. Horse manure disposal is one of the major challenges that most owners and managers have to face. Manure management for owners with limited land is much more challenging than for those with larger farms. As muck heaps can grow fast, using storing and removing them is a constant struggle. If you leave them unmanaged, you will expose yourself to compliance risk. Not just that, unmanaged manure also causes operational issues and leads to pollution.

However, given all these challenges, it does not mean you should not consider keeping your horse. In fact, it means you must follow best practices to ensure proper disposal of horse manure and continue enjoying time with your best pal. Following the right approach will not only help you manage land and waste better but also help you make the most of them. In fact, proper manure management can help turn this waste into a valuable asset.

Horse Manure: The Problem

Horses produce about eight piles of manure a day and about 50 pounds a day.

(Horse Stable Manure Management).

While horse lovers may believe that management of a single mount is not a big deal, the reality is different. On average, a horse produces about 50 pounds of manure a day. It means that one horse can generate multiple wheelbarrows of material over a week. In small yards, this can create several problems, including rapid muck heap growth, limited storage space, a high risk of runoff into drains, and increased odour.

If you fail to manage manure properly, it will become waste rather than a fertiliser resource. In particular, if you store it without a proper plan or if manure poses a pollution risk, it will be considered waste. As a result, you will lose a valuable resource and expose yourself to legal action if you do not properly manage muck heaps.

Is Manure Waste?

Unlike general perception, horse manure is not considered waste. In fact, it is recognised as a valuable organic fertiliser. But manure becomes waste in certain cases. For example, if it leads to pollution or is stored indefinitely with no use, it will be considered waste under the law. Likewise, if you do not properly manage it or it causes runoff, it will no longer be a valuable fertiliser but rather waste.

Under the Waste Framework Directive and the Environmental Protection Act 1990, every horse owner, small equestrian holding, or land manager is required to meet certain requirements for managing manure. The main rule is that if manure is used beneficially, it is not waste; but if it is discarded or unmanaged, it becomes waste.

Understanding the Importance of Manure

One of the most important things for ensuring that horse manure is not wasted is to understand that it is a valuable resource, not waste. It contains organic matter, which helps improve soil structure, Nitrogen, which is essential for plant growth, and Phosphorus, a useful mineral for root development. So, manure offers many benefits, making it a valuable resource for everyone.

It can be reused in various ways. You can spread it on pasture and composite into soil conditioner. It can also be supplied to gardeners or other landholders. Proper planning of reuse can help you avoid accumulation from becoming a compliance issue.

Manure Storage

Simply piling manure into a heap creates several problems.

• Pollution risk. Rainwater leaks nutrients out of the heap. This runoff can enter groundwater and streams, leading to legal compliance issues.
• Poor decomposition. Without proper aeration and turning, the heap becomes anaerobic, which slows decomposition and creates smelly waste rather than good compost.  
• Pests and flies. Manure heaps attract flies and rats.  

Instead of piling tons of manure, the right approach is to use the appropriate manure management methods. It will not only help you manage your farm better but also make the most of this valuable resource, prevent pollution and also avoid legal issues. This way, you can turn a problem into a useful resource with several benefits for your land.

Best Storage Practices

It is essential to follow the best practices for manure storage management. Here are some of the most effective storage methods that can help you stay compliant while managing horse manure efficiently:

• Store manure at least 10m from watercourses
• Keep it at least 50m from wells or boreholes.
• It must also be away from flood-prone ground.
• Make sure you store it on the right surface, preferably impermeable, as it helps prevent leachate from soaking into soil.
• It is also essential to ensure the heap is compact and stable, with minimal exposure to rainfall.

All these steps will help minimise the risk of pollution while aligning with expectations under the Farming Rules for Water.

Composting – Turning Waste into Valuable Product

Considering the high value of manure, you must look for the best ways to make the most of it. Composting is one of the most effective ways to convert this resource into a usable product. It has several benefits:

• It improves soil health by adding organic matter and nutrients.
• Reduces parasite risk by removing manure from grazing areas.
• Cuts down odour and flies.
• It reduces runoff and helps protect nearby waterways.
• Creates more manageable waste by saving space.
• Allows you to sell or give away excess compost to other farms.

3-Bin System

You can use an open pile system or go with a 3-bin system for proper composting.

• Bin 1: Add fresh waste daily
• Bin 2: Actively decomposing, turned regularly
• Bin 3: Curing or finished compost

Compared to piles, composting in a bin system is better because it keeps materials enclosed and separated, requiring less space. A 3-bin system works well for managing waste from fewer horses.

You need to construct bins next to one another. A bin or a pile must be at least 3 feet wide, 3 feet tall, and 3 feet long.

Bin 1 is where freshly collected waste is deposited. Bin 2 contains the “composting” pile, while Bin 3 contains the finished product, ready to use.

Land Spreading

Another way to make the most of manure is to spread it on land.

What is the One-Horse Per Acre Rule?

The “one horse per acre” rule means land does not receive too much manure. Each horse produces a large amount of manure. If there are too many horses in a small area, the soil will become nutrient-rich. Nutrients such as nitrogen help grass grow, but too much can damage it and wash into water through rain. The Environment Agency recommends not exceeding 170 kg of nitrogen per hectare per year from organic manures. So, it means that you can keep roughly one horse per acre, which usually keeps nitrogen levels close to the safe limit.  

Land Spreading: Best Practices

Do not overload the land. Make sure you follow the one horse per acre rule, as exceeding this can overload soil with nutrients.

Compost. It is important to compost horse manure before spreading it, as it will help reduce volume and kill parasites and weed seeds.

Apply the right amount. You need to spread the right amount of manure to avoid damaging grass or causing runoff.

The right time. It is important to spread in early spring or early autumn as the grass can absorb nutrients well during these times. It is always recommended to avoid winter, heavy rain or waterlogged ground.

Protect watercourses. Make sure you keep at least 10 metres away from streams and ponds to stay compliant with the law.

Rotation. Make sure to follow best practices, such as rotation, as it will help support long-term soil health.

Rest the field. Leave the land for 4–6 weeks after spreading and harrowing to improve distribution.

When to Call a Professional Collection of Horse Manure

It is best to call a professional waste carrier when the manure pile becomes too large to manage, or if it starts causing strong smells, or risks runoff into watercourses. Professional collection is very important when on-site storage or spreading is no longer practical. A waste company can also help when you do not have enough land to spread manure safely within recommended nutrient limits. They will help remove manure while remaining compliant with the regulations. A professional removal company transports the waste to approved sites, leaving your land clear and safe.

Hiring a professional waste-handling service can also be useful during winter, when fields are too wet or frozen to be spread. By hiring a professional, you can keep your yard clean, safe, and compliant with legal requirements. It will help you ensure responsible disposal, prevent pollution and reduce environmental risk.

Horse Manure Disposal – From Problem to Peace of Mind

Remember that you can only continue to keep enjoying your horse when manure is managed well. The manure problem can become an asset with proper management. You must know that the difference between waste and resource depends entirely on intent and proper planning.

Storing waste effectively, using the bin method, and spreading can help you turn manure from a burden into a valuable asset while avoiding legal complications.

Professional waste handling services can also help you with proper horse manure disposal. You can hire them if on-site storage or spreading doesn’t work or if there is a risk of pollution. They will help you keep your land clean, clear, and practical for your horse management.
