Biochar, Nutrient Control and Cow Urine

Biochar offers an alternative way to reduce nitrogen run-off, fertilise pasture, and prevent the pollution of creeks, rivers and reefs.

A study by a young Queensland scientist researches how carbon can be used to keep cow urine out of waterways. With each cow capable of producing on average half a litre to two litres of liquid each day, it is estimated in Australia that between 65 to 312 million litres of cow urine enter our environment every day. Cow urine presents an issue in waterways due to its ability to form into algae blooms.

This study has found that biochar added to the soil has the ability to reduce nitrogen leaching by 70 per cent. It was also proven that Biochar is a great food source for the microbes increasing their productivity.
