A SIMPLE AERATOR FOR NUTRIENT SOLUTIONS [PDF]
Plant 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

CHELATION OF TRACE METALS IN NUTRIENT SOLUTIONS [PDF]
Plant Physiology, 1950 The effect of chelating agents added to nutrient solutions on plants growing in these solutions was investigated. Chelating chemicals used were: 8-hydroxyquinoline (oxine), sodium diethyldithiocarbamate (carbamate), sodium 1:8 dihydroxynaphthalene 3:6 disulphonate (chromatropic salt), sodium 1-nitroso-2-naphthol 3:6 disulphonate (nitroso-R-salt ...
