Three Ways to Make Your
Garden Say "Holy Carp."

Holy Carp!
Fish-powered nitrogen

Dead fish, reborn as the best thing that ever happened to your leafy greens. It smells like the dock at low tide. Your kale won't stop growing.

Holy Cow!
All-purpose soil conditioner

The workhorse. Bovine biomass turned into a balanced pour that drags dead, tired dirt back from the grave. Barnyard-scented. Absurdly effective.

When Pigs Fly!
Heavy-hitter bloom booster

The one that gets results nobody believes are real — hence the name. Pig biomass, maximum funk, for growers who want the whole block asking questions.

// Also in 32oz, 64oz, and the 250-gal tote for people who are dead serious about their tomatoes.

// The Smell Is the Sales Pitch

Yeah, It Reeks.
That's the Whole Point.

01
It's Real

Synthetic fertilizer smells like nothing because it's nothing but salt. Barco stinks because it's actual organic matter — food your soil recognizes on contact.

02
It's Alive

That barnyard punch is biology doing its thing. Same reason fish emulsion and manure tea have been the dirty little secret of great gardeners for a century. The nose knows.

03
It Fades

Water it in and the funk clears out in a day or two. What sticks around is the part your plants care about. Short-term stink, long-term green.

// The Case File

We Sent It To A Lab.
The Results Are In.

We shipped all three straight to a certified Oklahoma DEQ lab and told them to throw the book at it. Turns out the stuff that smells like death is absolutely packed with life — and clean where it counts. Receipts below.

Cleared
Finding 01
No Detectable Heavy Metals

Arsenic, lead, cadmium, cobalt and molybdenum all came back below the lab's detection limits. Made from animal biomass — clean where it matters.

// As · Pb · Cd · Co · Mo — none detected
Potent
Finding 02
Loaded With Potassium

Up to 26,000+ mg/L potassium — the "K" in N-P-K that feeds roots, fruit and hardiness. The good stuff, quantified.

// Potassium-rich · nitrogen-heavy
Alive
Finding 03
BOD: 22,572

Biological oxygen demand off the charts — the lab's way of measuring how much life is packed in the bottle. That's why it reeks. That's why it works.

// How It's Made

Something Died So Your
Garden Could Live.

Bones · Hide · Fat → Alkaline Hydrolysis → Liquid Fertilizer

Barco — the Bio Advantage Recycling Company of Oklahoma — uses a water-based, low-energy process called alkaline hydrolysis to break animal biomass down to its raw building blocks, then rebuilds it into biobased fertilizer. It's rendering, reinvented: nothing wasted, no synthetic chemicals, and a whole lot less headed for the landfill. It's a little morbid. It's completely responsible. And your plants have never eaten better.
