Transforming Agriculture with Sustainable Organic Solutions
About Rihemu Organic Inputs
Rihemu Organic Inputs Limited offers our proprietary product, Rotuba Bio-Fertilizer. Through our patented method, we produce a fertilizer that disrupts the very concept of organic farming. We take the unproductivity, cumbersomeness, and imprecision out of organic farming.
We launched in April 2021, and since then, we have continued to perfect our product and realize satisfied customers.
Our Guiding Principles
Vision
Mission
Rotuba's Agricultural Transformation
Since it was founded, Rotuba has mobilized farmers across Murang’a County to transform their agricultural practices and provided a solution to rehabilitate damaged or exhausted soils and address declining agricultural productivity, which are key to meeting the region’s agricultural production challenges over the next two decades.
At the moment, we have a plant in Embakasi, Nairobi, that produces 3,000 50-kg bags of organic fertilizer per year. It has one permanent worker, two part-time workers, and twelve casual staff.
Unlocking Organic Farming Excellence
Our Value Proposition
Our Value proposition is that we provide a highly productive, convenient (not bulky) organic resource that has application convenience – Only 3 bags per acre. It restores natural soil fertility; it is standardized and precise. It has the KEBS mark of quality. It is certified by Coffee Research and KEPHIS, with International Certifications on the way.
It is an innovation on non-humified composts and manures which tend to have unpleasant odors, imprecise compositions, and are bulky and cumbersome to process. We are the bridge from manures to Bio-fertilizers, and we make Organic farming the only way to farm.
