From Waste to Field: The Science Behind Our Microbial Biofertilizers and Biopesticides

Most farmers who use a biofertilizer or biopesticide never see how it's made — understandably, since the interesting part happens well before the product reaches a shelf. For Becof, that process runs through two very different environments: a university microbiology lab and a production facility built around sorting and processing organic waste. Here's how they connect.

Why We Work Through a Research Partnership

Producing a biological input starts with a specific, deliberate step: isolating and growing the microorganisms that will eventually go into the product. Doing that reliably requires a microbiology laboratory — controlled environments, sterile culturing equipment, and the expertise to identify and maintain the right microbial strains at scale.

Becof does not yet operate an in-house microbiology laboratory. Rather than treat that as a barrier, we built our production model around a partnership with the Technical University of Kenya, whose microbiology facilities and researchers handle the culturing and harvesting of the microorganisms used across our biofertilizer and biopesticide lines. It's a model we're transparent about: it lets us produce biologically rigorous products today, on a realistic timeline, while we work toward building our own laboratory capacity over time.

What "Culturing and Harvesting" Actually Involves

In microbiology, these are specific, sequential steps, not interchangeable terms:

• Culturing is growing a microbial strain in a controlled nutrient medium, under conditions — temperature, oxygen level, pH — tuned to that organism, until the population reaches the density needed for a viable product.

• Harvesting is the process of recovering that biomass from the culture medium, separating the live microorganisms from the liquid they were grown in, so they can be formulated into a stable product.

This is the stage where product quality is actually determined. A biofertilizer's effectiveness in the field depends directly on how carefully the culturing and harvesting were done — an under-cultured or poorly harvested batch simply won't contain enough live organisms to make a measurable difference, regardless of how it's marketed.

Inside the Production Facility: Ongata Rongai, Kajiado County

Once the cultured microorganisms are ready, production moves to our facility in Ongata Rongai, which handles three connected functions:

• Waste sorting. We process organic waste as a feedstock for our biofertilizer production — a deliberate circular-economy choice that turns a disposal problem into a productive input, rather than sourcing virgin raw material.

• Manufacturing. The sorted organic material and cultured microorganisms are combined and processed into our finished biofertilizer and biopesticide products.

• Storage. Finished product is stored on-site under controlled conditions ahead of distribution to our partner network, since — as covered in our farming guides — biological products degrade if stored poorly.

The Science in Simple Terms: How Microbial Inputs Help a Crop

Without getting into specific proprietary formulations, it's worth explaining the broad categories of biological mechanism this entire industry — Becof included — is built on:

• Nitrogen fixation. Certain bacteria can convert atmospheric nitrogen, which plants can't use directly, into a form plants can absorb through their roots, reducing dependence on synthetic nitrogen fertilizer.

• Phosphate solubilization. A significant share of the phosphorus already present in most soils is chemically locked up and unavailable to plants. Certain bacteria and fungi release organic acids that free up this "locked" phosphorus, making nutrients already in the soil usable rather than requiring more phosphorus input.

• Mycorrhizal associations. Some fungi form symbiotic relationships with plant roots, effectively extending the root system's reach for water and nutrients far beyond what the plant could access alone.

• Biological pest control. Certain beneficial microorganisms suppress crop pests and pathogens through competition for resources, direct antagonism, or by triggering the plant's own natural defence responses — the mechanism behind biopesticides, as distinct from the broad-spectrum toxicity of synthetic chemical pesticides.

These are well-established mechanisms in agricultural science; the research and production work lies in identifying which specific organisms perform well in Kenyan soil and climate conditions, culturing them reliably, and getting a viable population into a farmer's field in usable form. That's the work our Technical University of Kenya partnership and Ongata Rongai facility are built to do.

What's Next

Our current model — research partnership plus dedicated production facility — is deliberately built to scale. As the business grows, an in-house microbiology laboratory is a natural next step, one that would let us broaden the range of microorganisms we work with and shorten the path from research to product. Until then, this partnership approach lets us hold ourselves to a real scientific standard rather than compromising on it while we grow.
