Sprayable biodegradable polymer shows promise

摘要

CSIRO is developing a sprayable biodegradable polymer membrane technology for use in agricultural crop production systems to minimise soil evaporation, suppress weeds and improve crop water productivity in order to increase crop yields, farm income and farm profitability.This patented technology is undergoing pre-commercial trials. The sprayable technology has been demonstrated in laboratory pot experiments and in irrigated field plot trials using melons, sorghum and cotton. These trials have confirmed increases in cropwater productivity in excess of 30 per cent compared with bare soil treatments.
