BENEFITS OF GEOLSEC

Organic farming is the fastest growing sector of the global economy. Australia is the largest organic producer globally with 12 million hectares under organic cultivation.

Our organic phosphate fertiliser is environmentally and nutritionally superior to chemical fertilisers and can be used on a wide variety of crops and pastures.

Organic fertilisers based on ground-up rock phosphate such as GEOLSEC offer several advantages over chemically processed soluble fertilisers such as DAP, MAP or superphosphate:

  • Organic fertilisers slowly release nutrients into the soil matching the speed at which the nutrients are being absorbed by the plants.
    Phosphate rocks are natural minerals requiring minimum metallurgical processing. Their direct application avoids the production of polluting wastes such as phospho-gypsum and greenhouse gases, thus resulting in energy conservation and protection of environment from industrial pollution.
  • Phosphate rocks for direct application can be more efficient than artificial fertilizers in terms of phosphorus (P) recovery by plants under certain conditions. Based on the unit cost of P, natural phosphate rock is usually the cheapest.
  • Use of organic phosphate rock reduces the risk of harmful accumulation of nutrients in the soil and reduces soil salinity problems
  • Use of organic phosphate instead of chemically processed phosphate avoids the serious environmental degradation caused by increased concentrations of fertilisers in the ground water, the rivers and the coastal waters.
  • Phosphate rock has the ability to restore microelemental and microbial soil balance which in turn leads to less reliance on artificial fertilisers and better crop yields.
  • Plants grown on organic phosphate rock fertiliser have a better nutritional quality.
  • Because of phosphate rock's unique chemical composition, incorporation of phosphate rock into the soil enhances its biological activity and increases soil carbon (C) accumulation, leading to improved soil fertility and restoration of its physical and chemical properties.
  • Organic phosphate rock is a source of several nutrients other than P. Rock phosphates are usually applied to replenish soil P status, but phosphate rock also provides other nutrients not present in soluble fertilisers. Application of organic phosphate has a potential trigger effect on plant growth and crop yields as a result not only of P release but also of phosphate rock's effect on increasing exchangeable calcium (Ca) and reducing Al saturation.
