Re: Albrecht System for soil testing and fertilisation

[Rambler]

Hi All 
I am reading volume one  "The Albrecht Papers" Throughout he talks of
clay as being the "jobber" or the "go between". [I see a link to horn
clay here]
His experiments with clay was to add to colliodal clay the various
fertislers like Calcium, Potash,Magnesium,Sodium etc  and then  measure
plant growth responses depending on the level of fertiliser applied
Calcium came out at the top of the list from this developed CEC.Cation
Exchange Capacity.  As i understand it different crops have a different
CEC values.I am looking for such information.
If I understand the purpose of clay properly it takes  fertiliser and
turns it into a form that allow the roots to uplift the nutrient into
the plant in the right quantities required.  
 From reading Albrecht I am able to understand Steiners work better. 
 Seasons greetings and blessings to all for a happy new year
