Frequently asked questions
Quick answers about glauconite and the Agri-K-Organic product.
What is glauconite (greensand)?
A natural green mineral found in soils and sediments that holds a good share of potassium. Agri-K-Organic turns Egyptian glauconite from Bahariya Oasis into a natural potassium fertilizer and soil conditioner.
Is it safe? What about heavy metals?
All eight heavy-metal elements tested in both El-Gedida samples are below the CFIA limits. See the heavy-metal table on the Soil Nutrition page.
How is it different from conventional potassium fertilizers?
Glauconite releases potassium slowly, so less is lost by leaching. Its pH (6.71–7.59) and salinity (0.056–0.128 dS/m) are low, so it does not acidify or salinize the soil, and it also supplies iron, magnesium and trace elements.
Which plants can it be used on?
The proposed product line covers flowers, vegetables and fruit, trees and shrubs, houseplants and lawns. It also suits new sandy lands because it retains water and nutrients.
Where does the ore come from?
From the El-Gedida area in Bahariya Oasis, where roughly 25 m of glauconite lies above the iron ore and is usually stripped as overburden.
How is the product packed?
In 25 kg bags on an automatic, precision-weighing line.
What application rates and field results are available?
Lab results are strong, but agronomic performance still needs field trials on Egyptian crops. Contact us for technical guidance on your soil and crop.
