Soil Sensors - NPK

NPK stands for Nitrate, Phosphate and Potassium. These are the core sensors used in our soil sensing device. 

 

Over-fertilising usually causes the soil nitrate levels to increase. Phosphate and potassium levels are also known to rise because of excessive fertiliser usage. 

Excessive fertilisation leads to an imbalance of salinity in the soil making it unsuitable for native plant life. Nitrates also pollute waterways and can cause eutrophication, which can harm marine ecosystems.
