Acids are often used in to adjust pH levels. They are very efficient, but represent a security hazard through handling. To minimize this risk, a liquid solution of ammonium nitrate was tested to adjust the nourishing solution (with recycling process). Two ratio levels of N-NH4 + and N-NO3 - were compared. The achieved yield with a high ratio is slightly higher to those with a low ratio and to those achieved in a standard green-house (pH adjusted with nitric acid). The quality of fruits of the high ratio and the standard green-house proceedings (sugar content, acidity and firmness) is pretty similar and better than that of the lower ratio.
