I am working my PhD on plant nutrition (boron deficiency in Olea
and I could use a book on how to use hydroponics to study plant
The only one I have is "Sand and water culture methods used in the study
Plant nutrition" writen by E.J. Hewitt. It's a fine book but rather old
(1952). Any suggestions?
Thanks for reading,
