The research behind PCAT BLOCK C.
Everything we claim, where it comes from, and what is still being verified. We publish methods and numbers as they are confirmed — honestly, with no inflated promises. This page is the single place to hold us to that.
The SCIT (Jengamvura) trials, Chirumanzu.
On the two names: the published record — The Herald in 2019, and HIT's EMRECC centre, which lists it among its research projects — calls this technology SCIT. In the field it is known as Jengamvura. Same system; we lead with SCIT because that is the name you can look up and verify.
PCAT BLOCK C was developed by Power Conservation Ag Clinic Trust (PCAT) over more than a decade and incubated at the Harare Institute of Technology. Its proving ground was SCIT — Scientific Conservation Irrigation Technology, known colloquially as Jengamvura — a spot-irrigation system developed by PCAT engineer and HIT lead researcher Joseph Ngirande after eight years of research, and piloted by PCAT with HIT in Chirumanzu and elsewhere. SCIT fills planting stations with compost that absorbs water and releases it as the soil dries, watered at about one litre per station per week — so compost is the engine of the system, not an add-on (The Herald (Sallomy Matare), 2019 — republished by CFU Zimbabwe).
On those trial plots, the integrated system — Block C compost, planting-station potholes and precision spot irrigation — reached up to 18 t/ha of maize, far above typical smallholder yields, with Block C as its soil-and-moisture core. That figure is a field result from the project, not a marketing projection, and the full write-up publishes alongside our lab data.
Scope note: SCIT was reported as usable for all crops except tobacco and potatoes (The Herald, 2019), and our validation covers maize, soya and horticulture. We don't make claims for tobacco or potato programmes — if that's your rotation, talk to us and we'll be straight about what we do and don't yet have data for.
Achieved on experimental plots in PCAT/SCIT field trials using the integrated system: compost-filled planting stations and precision spot irrigation — with compost as the soil-and-moisture core. Not a typical smallholder yield.
Power Conservation Ag Clinic Trust (PCAT) developed PCAT BLOCK C and owns the technology. The compost is made in Zimbabwe, from local inputs, for Zimbabwean soils — no imported raw materials, no forex exposure.
Harare Institute of Technology (HIT) — Dept. of Environmental Management upholds the scientific standards behind the product. Governed by a signed MOU: PCAT owns the technology; HIT upholds the science. HIT is not a seller or endorser — its role is the science.
HIT's Environmental Management, Renewable Energy and Climate Change Research Centre — a Centre of Excellence working on sustainable water, waste and energy technologies, with agriculture among their applications. Its published research projects list SCIT, describing it as using "zero tillage, vermi-ferts, and thermal compost, mulch and conservation pots".
- ✓ Up to 18 t/ha maize from the integrated SCIT system (Block C as its soil-and-moisture core) on trial plots in Chirumanzu — a field result, documented within the project
- ✓ More than a decade of development by PCAT, incubated at HIT
- ✓ A signed MOU governing the PCAT–HIT relationship
- ✓ Public reporting of the technology and the trial result in the national press (The Herald, 2019) — not just our own word
- ✓ A second, independent institutional record: SCIT appears on HIT/EMRECC's own published list of research projects — so the technology behind the compost is documented by the university, not only by us
- ✓ Locally produced, sieved and bagged in Zimbabwe — sold by volume (50 L)
- → Full NPK nutrient profile (independent laboratory)
- → Quantified pH effect on acid soils
- → Measured moisture-retention performance
- → Formal registration paperwork
Each of these publishes on this page and the product page, unedited, the moment it is confirmed. Until then, we don't quote numbers we don't have.
A technology is only useful once it reaches a field.
Plenty of good Zimbabwean research never gets past the trial plot. Bridging that gap takes a route from laboratory to farm: development, testing, demonstration, farmer feedback, training, and finally supply a farmer can actually buy from.
That route exists here. Harare Institute of Technology runs a Technology Transfer, Licensing and Commercialisation Centre, which publishes 68 registered intellectual-property rights, four licensing agreements and sixteen startups and spinoffs, alongside an innovation hub for incubation and mentoring (figures as published on its site, which carries no date stamp). It is the formal mechanism by which technology developed at HIT is protected, licensed and taken to market.
321 Organics is the last step of that chain for one specific input: we make a locally developed compost available in bags a farmer can buy, and we publish the growing knowledge around it free. That is a deliberately modest claim — we are the supply and knowledge layer, not the research.

- Numbers before adjectives. Every measurable claim on this site is either cited, shown in a trial table, or explicitly marked as in verification.
- Sources on every guide. All Knowledge Hub articles carry a sources block — institutional and peer-reviewed references first.
- No claims ahead of data. We don't list crops (like tobacco or potatoes) that our validation doesn't cover, and we don't invent application rates where none are published.
- Unedited lab results. When the independent analysis returns, it goes up as received — including anything unflattering.
- Visible corrections. If we get something wrong, we fix it on the page and say so.
Want the deeper science? Start with what Zimbabwe's own trials show about organic vs inorganic fertiliser, why our soils turn acid, and the cited application rates by crop.
