Listening to Dr Ingham�s tapes and to some of her lectures I have heard her saying many times that " plants are passive sponges" and sometimes she makes a suction sound with her mouth to exemplify this feature. For those of you that knows her more closely it would be ideal to send her a copy of the article " Insoluble yet Available" by Dr William Albrecht found in volume I in which he explains why this isn�t so. I have also another evidence to demonstrate that plant absorption of nutrients does not follow any known physical-chemical law. Generally mineral concentration inside the rootlets is higher than in soil solution. But again, I have no PhD.
