Slow-release potassium
It dissolves more slowly than KCl or K₂SO₄, so less potassium washes out with irrigation.
Natural potassium from Egypt
We recover glauconite at the El-Gedida mine, where it is usually stripped as overburden above the iron ore, and turn it into Agri-K-Organic: a slow-release potassium fertilizer and soil conditioner.
Egyptian glauconite
Glauconite is a natural green mineral rich in potassium. At Bahariya Oasis a layer about 25 m thick sits above the iron ore of the El-Gedida mine, and miners usually remove it as waste. We put that layer to work.
An Egyptian ore that cuts reliance on conventional potassium sources.
Farmers have used glauconite as a potassium fertilizer for over 100 years.
Agri-K-Organic
It dissolves more slowly than KCl or K₂SO₄, so less potassium washes out with irrigation.
Grains and micropores hold water and nutrients near the roots.
Salinity is 0.056–0.128 dS/m. Nitrogen fertilizers reach 12.
Supplies iron and magnesium plus traces of zinc, cobalt and manganese.
Suits reclaimed sandy soils because it helps them hold water.
Mixing with compost improves potassium release.
Applications
Process
We recover greensand while overburden is stripped above the iron ore.
We grind the ore below 1 mm.
We keep the 125–250 µm cut and reject clay fines.
We test K₂O, heavy metals, pH and salinity.
We fill 25 kg bags on an automatic weighing line.
Quality & safety
We tested eight elements in two El-Gedida samples, east and west. Every result came in under the limit. Figures below are ppm for El-Gedida East.
Lab results are strong. Field trials on Egyptian crops are still needed.
| Element | Sample | CFIA limit |
|---|---|---|
| Cu | 3.7 | 400 |
| Pb | 2.0 | 150 |
| Zn | 86 | 700 |
| Ni | 15.4 | 62 |
| As | 2.4 | 13 |
| Cd | <0.1 | 3 |
| Co | 25.8 | 34 |
| Cr | 110 | 210 |
FAQ
A natural green mineral found in sediments that holds a good share of potassium. We mine it at Bahariya Oasis and turn it into a fertilizer and soil conditioner.
Yes. All eight elements we tested in both El-Gedida samples are below CFIA limits.
It releases potassium slowly, so less is lost to irrigation. It does not acidify or salinize soil, and it adds iron and magnesium.
