Pro Microbes

Biological fertilizer

One of the most effective and least expensive biological fertilizers on the market, formulated to build soil organic matter fast with a proprietary blend of hardworking microbes and essential nutrients.

Why growers use it

Everything a fertilizer does, and it builds the soil too.

Pro Microbes delivers benefits similar to conventional fertilizers, and it also ignites microbial life in the soil and activates the native microbes already present.

01Build soil organic matter

The cornerstone of the SOM protocol. Pro Microbes is an organic NPK biological fertilizer formulated to build SOM rapidly with carefully selected microbes, while activating the native microbes already in your soil.

It accelerates the breakdown of crop residues and other organic materials into nutrients and humic substances, forming humus-rich soil with better structure, aeration and water retention. It’s ideal for conventional, organic and regenerative operations and soil restoration projects.

02Maximize microbial activity

Pro Microbes stimulates existing microbial life and adds beneficial microorganisms that break down organic matter, fix nitrogen and solubilize phosphorus. Customers consistently see better soil structure, water retention and disease suppression.

03Balance soil pH

A specialized blend of beneficial microorganisms helps regulate soil acidity or alkalinity, correcting imbalances from acid rain, over-fertilization or depletion, and stabilizing pH swings so plants can take up nutrients.

04Big results at a low cost

Farmers consistently see healthier crops, significant yield increases, up to 20% less water use and fewer predatory pests. It is also one of the least expensive solutions available.

05Sustainable nitrogen

The microbes were selected for their ability to make nitrogen bioavailable, and they support efficient use of all forms of nitrogen, synthetic and organic. Nitrogen makes up 78% of the air, but crops can’t use it in that form; relying on other forms has led to over-nitrification and leaching.

06Reduce chemical inputs

Pro Microbes works alongside other fertilizers and amendments, but most users find it reduces or even eliminates the need for chemicals and pesticides. How higher °Brix reduces pesticide use.

07Reduced need for watering

More tilth and more efficient nutrient uptake mean less watering all around. Many of our farms have seen up to 20% less water use.

08Remediate soil and reduce algal blooms

Billions of beneficial microorganisms live off imbalances in an ecosystem and bring it back into balance. They help remediate soil toxicity and are an inexpensive way to control algal blooms.

09Easy to apply

Pro Microbes is activated at our warehouse and delivered directly to you. Add it to the mixing tank with our other products and apply through your irrigation system. Apply within one week of receipt to ensure active microbial life.

Feed plants and soil the way nature intended

It ignites nature’s own fertilizer factory.

Starting from nature’s design, we engineered and patented a proprietary technology to heal and nourish the soil.

First it creates an ideal environment for microbes by flocculating (relaxing) the soil. Enzymes added to that relaxed soil activate a flush of dormant native microbes, and we introduce billions of hand-selected microbes paired with diverse carbon sources. The result is more humus and a natural system of nutrient cycling.

As roots reach into the soil, resident microbes attach to them and form a symbiotic relationship, feeding on our sea kelp and on plant exudates for the energy to colonize further.

Nitrogen: natural nitrogen is absorbed more readily than synthetic. Pro Microbes sustains free-living nitrogen fixers that tap the roughly 30,000 tons of nitrogen gas above every acre. Phosphorus: beneficial bacteria free up insoluble phosphate locked in soils with a history of fertilizer, for higher yields, better harvests, more root growth and higher °Brix.

What exactly is Pro Microbes?

Three ingredients, one living fertilizer.

Billions of microorganisms

A concentration of carefully selected microorganisms that wake up when activated and reproduce into a boom population. Carbon-sequestering microbes turn carbon sources into complex nutrients; nitrogen-fixing microbes pull unusable nitrogen from the air and deliver it to the roots.

Sea kelp

A fast-growing natural biostimulant with hormones that trigger growth and nutrient uptake. It helps remove detrimental fungi and pathogens like molds and mildews, and it’s high in potassium.

Mineral electrolytes

A proprietary blend of plant-oriented mineral electrolytes that gives billions of microbes the building blocks for enzymes and cell walls.

Make nitrogen bioavailable to the crop

Nitrogen when the crop needs it, without over-nitrification.

The microbes in Pro Microbes capture nitrogen gas from the air, convert it to ammonia and feed it directly to crop roots. Each microbe senses the crop’s needs and delivers the right amount of usable nitrogen through the season: peak nitrogen when the crop needs it most, less when it doesn’t.

Finally, a nitrogen solution that is both effective and sustainable.

“Our conventional fertilizer program yielded 12–14 bolls per plant. The field treated with Pro Microbes averaged 45–50 bolls per plant.”

No more shipping truckloads of fertilizer.

Pro Microbes is small, really small. New technology enables nano delivery, so a small amount of material achieves dramatic coverage and results, harnessing billions of microorganisms that bring life and balance back into the soil.
