What Exactly is Compost?

Compost is often called “black gold” by gardeners, and for good reason! It’s essentially decomposed organic matter. Imagine a big pile of kitchen scraps, yard waste (like leaves and grass clippings), and other biodegradable materials. When given the right conditions – air, moisture, and time – these materials break down thanks to tiny organisms like bacteria and fungi. The end result is a dark, crumbly, nutrient-rich material that’s fantastic for your soil.

Think of compost as a multi-vitamin for your soil. It’s a complex mix of nutrients that are released slowly, feeding your plants over time. It also does wonders for your soil’s structure, helping sandy soils hold more water and making clay soils drain better. It’s truly nature’s recycling program!

How is Compost Made?

Making compost is a bit like baking a cake, but with organic materials and a lot less precision! You need a good mix of “greens” and “browns”:

• Greens: These are nitrogen-rich materials. Think fruit and vegetable scraps from your kitchen, grass clippings, and coffee grounds.
• Browns: These are carbon-rich materials. Examples include dry leaves, shredded newspaper, straw, and twigs.

You layer these materials in a compost bin or pile, keep them moist (like a wrung-out sponge), and turn them occasionally to let air in. Over weeks or months, the magic of decomposition happens. Many local municipalities offer great resources on home composting. For instance, the U.S. Environmental Protection Agency (EPA) has a comprehensive guide on how to start composting at home.

What is Manure?

Manure is, quite simply, animal waste. It’s mostly from farm animals like cows, horses, chickens, sheep, and rabbits. For centuries, farmers and gardeners have known that animal manure is an incredible soil amendment. It’s packed with nutrients that plants need to grow strong and healthy, and it can really boost the fertility of your garden beds.

However, not all manure is created equal, and using it fresh or improperly can cause problems. We’ll get into that in a bit, but the main thing to remember is that manure is primarily a source of nitrogen and other essential plant nutrients.

Types of Manure and Their Differences

The type of animal manure matters because it affects the nutrient content and how it should be handled. Some common types include:

• Cow Manure: This is generally considered a “cooler” manure, meaning it’s less likely to burn plants if not composted thoroughly. It’s a good all-around fertilizer, providing a nice balance of nutrients and improving soil structure.
• Horse Manure: Often higher in nitrogen than cow manure, horse manure can be very potent. It’s often higher in weed seeds if the horses ate hay containing them, so it really should be composted first.
• Chicken Manure: This is “hotter” and richer in nitrogen and phosphorus than other manures. It needs to be composted or aged for a long time before applying directly to the soil to avoid burning plant roots.
• Sheep/Goat Manure: These are considered “medium” manures, generally less potent than chicken manure but richer than cow manure. They are good all-purpose fertilizers.
• Rabbit Manure: This is a fantastic, balanced fertilizer and is often called “cold” manure, meaning it can be used fresh in the garden more readily than most others. It’s also rich in phosphorus and potassium.

It’s important to note that the diet of the animal also influences the manure’s composition. For example, manure from animals fed a grain-based diet will differ from those fed primarily grass.

Compost vs Manure: The Key Differences

Now that we know what compost and manure are, let’s break down the compost vs manure difference more directly. While both are organic amendments that improve soil, they have distinct characteristics:

Nutrient Content:

• Manure: Typically higher in readily available nitrogen and other specific nutrients like phosphorus and potassium, depending on the animal source. It acts more like a direct fertilizer.
• Compost: Provides a broader spectrum of nutrients, but often in lower concentrations. These nutrients are usually released more slowly, acting as a sustained-release fertilizer. It’s more balanced.

Weed Seeds and Pathogens:

• Manure: Fresh or improperly composted manure can contain weed seeds and harmful pathogens (bacteria like E. coli or Salmonella) that can be dangerous to humans and can spread weeds throughout your garden.
• Compost: A well-managed compost pile heats up sufficiently (reaching internal temperatures of 131-160°F or 55-71°C) to kill most weed seeds and pathogens. This makes compost generally safer to handle and use around food gardens. The National Agricultural Library also discusses the importance of proper composting temperatures.

Soil Improvement Qualities:

• Manure: Especially aged or composted manure, adds organic matter, which improves soil structure, drainage, and water retention.
• Compost: Excellent at improving soil structure. It enhances aeration, water-holding capacity, and drainage in all soil types. It also boosts beneficial microbial activity in the soil.

Ease of Use:

• Manure: Needs to be aged or composted properly to avoid “burning” plants with excess nutrients or introducing pathogens/weeds. Sourcing can also be a challenge for urban gardeners.
• Compost: Generally easier and safer for beginners to use. It can often be applied directly to the soil or around plants without much worry. You can also make your own easily.

Compost vs Manure: A Comparative Table

Let’s put this side-by-side in a table to make the compost vs manure difference even clearer:

Ease of Use for Beginners	Very Easy	Moderately Easy (needs some aging/composting)	Difficult/Not Recommended
Soil Structure Improvement	Excellent	Good	Good
pH Impact	Generally neutral, minimal impact	Slightly alkaline to neutral, depends on source	Can vary significantly

When to Use Compost

Compost is your go-to amendment for almost any gardening situation. It’s a fantastic all-rounder!

• Improving Soil Structure: If you have heavy clay soil that drains poorly or sandy soil that dries out too quickly, compost is your best friend. Mix it into your garden beds before planting.
• Feeding Plants: Sprinkle a layer of compost around existing plants as a top dressing. It will slowly release nutrients and improve the soil surface.
• Starting New Gardens: Incorporate a generous amount of compost into new garden beds. It provides essential nutrients and helps establish healthy soil from the start.
• Container Gardening: Compost is an excellent addition to potting mixes. It provides aeration, drainage, and slow-release nutrients for plants in pots.
• Lawn Care: Top-dressing your lawn with a thin layer of compost in the spring or fall can revive tired turf and improve soil health.
• Seed Starting: A good quality, fine compost can be mixed with other materials for seed starting mixes.

Think of compost as the foundation for a healthy, living soil ecosystem. It feeds the soil microbes, which in turn feed your plants!

When to Use Manure

Manure, when properly prepared, is a potent nutrient boost. It’s best used when you need to add a significant amount of nitrogen or are dealing with nutrient-depleted soil.

• Boosting Fertility for Heavy Feeders: Plants like corn, tomatoes, squash, and fruit trees are often called “heavy feeders” because they use up a lot of nutrients. Well-rotted or composted manure can provide the boost they need.
• Amending Tired Soil: If your garden soil seems depleted after years of use, balanced, composted manure can help replenish the nutrient profile.
• As a Component in Compost Piles: Manure can be an excellent “green” ingredient in your own compost pile, helping to heat it up and speed decomposition. Just make sure to compost it thoroughly.
• Sweetening Sour Soil: Some animal manures, particularly poultry and rabbit manure, can help balance acidic soils.

Crucial Note on Manure: Never use fresh, uncomposted manure directly in your garden where you plan to grow edible crops. The risks of pathogens and excessive nitrogen burning plant roots are too high. Always use aged, composted, or “well-rotted” manure. If you’re buying manure, ensure it’s labeled as composted. If you’re sourcing it yourself, let it age for at least 6-12 months, or better yet, add it to your compost pile.

DIY Compost and Manure Management Tips

Want to take your garden game to the next level? Managing your own compost and sourcing manure can be very rewarding.

Starting Your Own Compost Pile

You don’t need fancy equipment. A simple bin made from wood pallets or chicken wire works great. Remember the green-to-brown ratio (roughly 1:2 or 1:3), keep it moist, and turn it regularly. For more detailed instructions, check out this practical guide from your local extension office, which often provides region-specific advice on composting: Alabama Cooperative Extension System – Composting Tips.

Sourcing and Preparing Manure

If you have access to local farms, you might be able to get manure for free or cheap. However, always ask how the animals are treated and what they are fed. Collect manure and consider a separate composting system for it, or add it in balanced layers to your main compost pile, ensuring it reaches high temperatures. For rabbit manure, it’s often safe to use fresh, but composting it still offers benefits like pathogen reduction.

When in Doubt, Compost It!

If you’re unsure about the quality or safety of manure, the best approach is to compost it first. This process neutralizes many of the risks and creates a safer, more beneficial soil amendment.

Common Questions: Compost vs Manure

Here are some common questions beginners have when trying to understand the compost vs manure difference:

Q1: Can I use compost and manure together?

A1: Absolutely! In fact, it’s a fantastic combination. You can add compost to your manure compost pile to balance it out, or mix both finished compost and aged manure into your garden beds for the ultimate soil boost.

Q2: Is manure bad for my garden?

A2: Not at all, when used correctly! The issue isn’t manure itself, but using fresh, uncomposted manure. This can burn plant roots, introduce weed seeds, and potentially harmful bacteria. Aged or composted manure is incredibly beneficial.

Q3: Which is better for vegetable gardens: compost or manure?

A3: Compost is an excellent, all-purpose amendment for any garden, including vegetable gardens. Aged or composted manure is also great for vegetables, especially heavy feeders, but it’s always best to ensure it’s well-rotted to avoid issues.

Q4: How much compost or manure should I use?

A4: For general soil improvement, mixing a few inches of compost into the top 6-8 inches of soil is a good rule of thumb. For aged manure, use it more sparingly, perhaps a thinner layer, or incorporate it into your compost pile. Always follow specific plant needs and soil test recommendations if available.

Q5: Can I put horse manure directly on my garden?

A5: It’s not recommended to use fresh horse manure directly on your garden, especially for edible crops. It’s often high in weed seeds and can be too rich, potentially burning plants. It should be aged for at least 6-12 months or composted thoroughly before use.

Q6: What’s the quickest way to get soil amendment benefits?

A6: Compost generally provides faster, more reliable benefits for beginners due to its balanced nature and reduced risk of weed seeds or pathogens. Properly composted manure offers concentrated nutrients, but requires more careful preparation.

Q7: Where can I buy compost or manure?

A7: You can often buy compost in bags at garden centers, nurseries, and hardware stores. Bulk compost and aged manure are usually available from landscape supply companies or agricultural feed stores, often at a lower price per cubic yard.
