AGRICULTURE

Fertiliser leaching has serious environmental and economic repercussions.
When fertilising crops, keeping precise timing and regulating nutrient levels are critical for plant health. High levels can “burn” crops, while low levels mean that crops will struggle to grow, and repeated applications of low levels of fertiliser can be laborious. In addition to the loss of resources and reduced crop yields, excess runoff from nitrogen and phosphorus fertilisers can pollute surface water and groundwater, especially in high rainfall areas.

CAPABILITIES AND OFFERINGS

Consultancy and Evaluation

 

Our polysulfide-fertiliser composite is matched to the needs of specific plants and allows for a slow and controlled release of nitrogen, phosphorous, and potassium (NPK) nutrients. This composite differs from traditional slow-release fertilisers, as it does not use a typical agriculture polymer coating, which can result in the release of residual, persistent microplastics.

Because of its versatility in managing the release of fertilisers, this composite can be applied to a variety of farming practices, either small or large.

Materials

 

The composite is made by combining the specific fertiliser nutrients (NPK) required by your crop with our polysulfide. The polysulfide is derived from canola oil and elemental sulphur.

The slower release of the fertiliser will help reduce loss of valuable nutrients in tailwater, prevent nutrient burn, supply nutrients at a level tuned to the plant’s growth, and lessen the environmental impact from run-off.

Future Development

 

In addition to the immediate benefits to the environment and economy, this material can be manufactured from waste cooking oil. In this way, food waste is converted into fertiliser and used to grow more crops—an important step in supporting a circular economy.
