Even well-aerated substrate crops may suffer oxygen deficiency as the result of factors, such as high root respiration rates, high crop water demands and high substrate temperatures. Several methods of nutrient solution oxygen-enrichment have been used to improve oxygen supply to the roots in hydroponic and substrate crops. The injection of pure, pressurized oxygen gas to the nutrient solution above saturation levels, known as oxyfertigation, has been commercially adapted for use in horticultural greenhouses on the Spanish Mediterranean coast.
