Development of Chlorine-Less Potash Mineral Fertilizer


Creation of small scale production of chlorine-less potash mineral fertilizer “ZEOKALI” with output of 2000 tons per annually is the aim of given proposal. Received fertilizer represents a commercial product by itself. Potassium is an irreplaceable compound of mineral fertilizers. Great interest towards non-traditional methods of reception of potash fertilizers from sea and ocean waters is shown in recent years in countries where potassium containing deposits are not available. The offered by us technology of extraction of potassium cations from sea-water and reception of potassium mineral fertilizers is based on specific character of dependency of system “sea water - Kl” from temperature, where Kl is used as a substratum and sea-water as a source of potassium. This effect enables to develop “dual-temperature” technology in which for concentration of potassium from sea-water does not require use of any chemical.

Innovative Aspect and Main Advantages

Presented technology for reception of potash mineral fertilizer is environment-friendly, no chemical reagents are needed and thus there are no by-products and toxic emissions.

Technology has following advantages:

  • Availability of accessible and cheap row material;
  • Simplicity, profitability and ecological compatibility of process;
  • High consumer qualities of received product (prolonged action, combination ability, absence of chlorine, conditioning properties);
  • Increasing of productivity of agricultural crops, reduction of toxic substances in plant and grain, improvement of plant and fruit structure.

Areas of Application

Received product “ZEOKALI” – klinoptilolite enriched by potassium can be used as complete fertilizer both in natural and artificial soils and irrigating systems. Product can be used by large and small agrarian and hothouse enterprises or farms inside and outside of the country. “ZEOKALI” will be cheaper than existing analogues approximately by 20%. Selling of received product in Southern Caucasus (Georgia, Armenia, Azerbaijan) and Black Sea coastal countries (Greece, Bulgaria, Turkey, Syria, Romania), in Saudi Arabia and Germany is very prospective. Selling of license and introduction of mentioned technology in sea coastal countries having deposit of natural zeolites is economically favorable as well.

Stage of Development

Presented technology is developed on the basis of long-term scientific researches and laboratory experiments at the Tbilisi State University in collaboration with Scientific-Research Institute of Membrane Technologies, Batumi. Pilot sample of end-product is available, laboratory tested. Model installation is under assembling and planned to be tested in field conditions by the Institute of Membrane Technologies.
