We pulled our latest lab results on the leaf mulch and wanted to share some of it, because honestly most people never see this kind of thing.

One number that jumped out the Compost Maturity Index came back as Early-Cure. For a finished compost that might sound like a red flag, but for leaf mulch that's actually a good thing. It means the material is still actively breaking down, which is exactly what you want from mulch. It's not done feeding your soil yet. It keeps going.

As it continues to break down it's releasing real nutrients — nitrogen at 1.07%, phosphorus at 0.14%, potassium at 0.34%, calcium at 1.80%, and magnesium at 0.31% on a dry basis. Organic matter tested at 73.7%, which is what's driving all of that breakdown and feeding your soil biology along the way.

Water holding capacity came back at 228% on a dry basis. That's more than double its weight in water it can hold huge for beds that dry out fast.

This is why leaf mulch isn't just something you put down and forget about. It's working the whole time it's on your bed, slowly releasing what's in it as it breaks down, right up until it finishes its job and becomes part of your soil.

THIS IS SOMETHING EVERY BUYER OF SOIL AND MULCH PRODUCTS NEEDS TO UNDERSTAND.

The word organic is not a suggestion. It is not a feeling. It is not a marketing decision.

Under the USDA National Organic Program the use of the word organic on product labels and in marketing is strictly regulated. It may only be used to identify agricultural products and ingredients that have been produced and handled in accordance with official NOP standards. 💪

That means if a company is putting the word organic on a bag of compost, mulch, or soil without the certification to back it up — they are not just misleading you. They may be in violation of federal regulations. That is how serious this is.

So the next time you see organic on a bag ask one simple question.

Where is the documentation?👇
OMRI Listed — approved for organic use.
OMRI is an independent nonprofit that reviews every single input in a product against strict national organic standards. If a product carries an OMRI Listed designation it means it has been vetted, verified, and approved for use in certified organic production. That is a fundamentally different level of accountability than a marketing claim on a bag.

No OMRI Listed designation means the word organic on that label is just a word. Nothing more. Nothing less.

At A.R. Plante Organics we earned our OMRI Listed designations because the people buying our products deserve to know exactly what they are getting. Verified. Documented. Accountable. ✅

No biosolids. No animal manure. No synthetic additives. No shortcuts.
Organic means something. Make sure it means something where you buy. 🌱

💪 CUSTOMER SERVICE IS NOT A DEPARTMENT. IT IS A CULTURE. AND OURS IS BUILT ON THREE THINGS.

Respect. Consistency. Honesty.

No complicated mission statement. No corporate language. Just three words that drive every decision we make from how we answer the phone to what goes into every yard of material that leaves our yard.

RESPECT.

Every person who calls us whether you are ordering a hundred yards or asking a single question deserves the same level of care and professionalism. Your time matters. Your project matters. Your trust matters. We do not take any of that lightly. 🤝

CONSISTENCY.

When you order our OMRI Listed compost today it needs to perform exactly the same as the load you ordered six months ago and the load you order six months from now. Consistent temperature management. Consistent feedstocks. Consistent screening. Consistent loads verified by our Industrial Load Scanners. Your business depends on knowing what is showing up before it shows up. 💪

HONESTY.

We will tell you exactly what is in our products and exactly what is not. No biosolids. No animal manure. No recycled industrial wood. No synthetic additives. No shortcuts. And if something is not right we will own it. No deflection. No excuses. We fix it.

Honesty in this industry is rarer than it should be. Products get mislabeled. Terms get stretched. Marketing language fills the gaps where transparency should be. We decided early on that we were never going to operate that way.

What we say our product is it is. What we say is not in it it is not. Full stop. ✅

Respect. Consistency. Honesty. Three words. One standard. Every single day. 🌿

🌱 THE BIG GUYS WON'T DO IT. WE WILL.

Every landscaper, contractor, and turf manager has been there. You have a spec in front of you. An engineered planting mix. A custom compost loam sand blend for a turf application. A unique ratio that your project actually requires.
And the big suppliers tell you — sorry, that's not something we do.
At A.R. Plante Organics it is exactly something we do. 💪
We have the equipment, the materials, and the expertise on site in West Bridgewater to produce custom soil blends and mixes built to your exact specifications. Whether you are working from an engineered planting spec or you just know what ratio performs best for your application — we can build it.
Here is where we see this making the biggest difference:
🌿 Engineered spec plantings — wetland blends, structural soils, rootzone mixes, and specialty planting applications that require a precise ratio of materials to meet project specifications. These are the jobs most suppliers walk away from. We build them.
🌱 Custom compost loam sand blends for turf — getting the right balance of organic matter, soil structure, and drainage for turf applications is a science. Too much of one thing and you are fighting compaction or drainage issues all season. We blend to your ratio using our OMRI Listed compost as the organic foundation — so you know exactly what biology and nutrients are going into that mix.
🏗️ Landscape contractor custom blends — need a specific mix for a high end residential install, a commercial project, or a unique application? Bring us your spec. We will build it.
Our on site screening and blending capabilities mean we are not limited to what comes off a standard production line. We work with you to get the mix right — and we back it with the same commitment to clean verified materials that goes into everything we produce.
No biosolids. No recycled industrial waste. No mystery inputs. Just clean organic materials blended to your spec and delivered with the accuracy our Industrial Load Scanners guarantee. ✅
If you have a project coming up that requires something custom — give us a call before you assume it can't be done. Chances are we can build it. 🚛

🌿 LET'S HAVE AN HONEST CONVERSATION ABOUT HORSE MANURE IN LEAF MULCH.

You will see it advertised everywhere. Leaf mulch blended with horse manure — marketed as rich, organic, and natural. To be fair there are situations where well managed horse manure has value. We want to be honest about that. But here is where the concerns start. 👇

🧂 HIGH SALT LEVELS.
Manure based composts tend to develop high concentrations of ammonium, calcium, magnesium, and sodium — all contributing to elevated salt levels. Salts can actually concentrate further during composting as moisture is lost — making the problem worse not better. Elevated salts stress plants and show up as red flags on your lab report.

💊 MEDICATION AND DRUG RESIDUE.
Horses are routinely treated with dewormers, antibiotics, and anti-inflammatories. Research shows 30% of veterinary drugs in animal manure pose measurable ecological risk — and composting reduces but does not eliminate them. If you don't know the medical history of the horses you don't know what residues are in your mulch.

🌱 HIGH AMMONIA FROM URINE.
Fresh horse manure can be so high in ammonia it damages the leaves and roots of plants. Without precise management that nitrogen spike creates more risk than benefit.

🌾 W**D SEEDS AND HERBICIDE RESIDUE.
Horses are poor digesters — w**d seeds survive and can sprout in your beds. Some manures also contain persistent herbicides from treated hay that can stunt or kill sensitive vegetables.

Do you know how the manure was managed? The medication history? The salt levels? If the answer is no that is your answer. 💪

🌱 WHY WE REPLACED PERLITE WITH RICE HULLS AND BIOCHAR — AND WHY IT MATTERS FOR YOUR PLANTS.

Most potting mixes use perlite for drainage and aeration. We made a different choice. Here is exactly why. 👇

WHAT IS WRONG WITH PERLITE?

Perlite is a mined volcanic glass heated and expanded for use in growing media. It creates air pockets that is it. It does not feed biology. It does not hold nutrients. It does not build long term carbon. And it is not renewable. 🚫

WHAT WE REPLACED IT WITH AND WHY.

🌾OMRI Listed Rice Hulls— a natural agricultural byproduct that provides the same drainage and aeration as perlite but breaks down slowly over time releasing silica — strengthening plant cell walls, improving disease resistance, and contributing organic matter back into the mix. Renewable. Clean. OMRI Listed. ✅

🔥OMRI Listed Biochar— this is where the real upgrade happens. Biochar creates a permanent porous carbon structure that colonizes with beneficial microorganisms, holds nutrients in the root zone, and dramatically improves water retention. Unlike perlite which drains water away biochar holds it right where plants need it.

IN THE POT — HERE IS WHAT CHANGES.

💧 Water retention improves — roots access moisture longer between waterings
🦠 Microbial communities colonize the biochar creating a living biological system inside the container
🌱 Nutrients stay in the root zone instead of leaching through with every watering
☀️ Plants show greater resilience through heat stress and irregular watering

AS A SOIL AMENDMENT IN PLANTINGS — IT GOES FURTHER.

When used to amend landscape planting holes or raised bed soil the biochar does not just disappear. It becomes a permanent fixture in your soil profile building long term carbon, housing biology, and improving the growing environment season after season. The difference between filling a hole and building a living system. 🌍
