A SIMPLE AERATOR FOR NUTRIENT SOLUTIONS [PDF]

open access: yesPlant Physiology, 1949
Proper aeration is necessary, in most cases, for normal development of plants grown in nutrient solutions. In many research institutions a central air compressor makes air pressure available in laboratories and greenhouses through a piping system. When an air compressor is not available, enough air pressure for the aeration of nutrient solutions or for
