Dear stovers ,AJH and AD Karve
Humus is all the organic material content in soil 4-7 %
Best known pyrogallol from oak leaves tri-phenol sugar complex , it colours
blue with Iron ions .
You can test how much Ca takes 1 Kg oak leaves and others to get an idea
of the neutralizing power . pH indicator phenoftaleine for Africa could be
Red chou .
Low themperature char < 400°C could contain cancerogens naftalene and
antracene ea !
Chorosis ? Mind MgCl2 as fertiliser . Chlorine makes plants sick .
Charcoal is porous and can be a water buffer and holes for week micro roots
,holes filled with minerals Ca Mg K Na ao
Labile Aluminium is out of the colloid electrical bond to ionic form .
Zn and Al are amphotere so camelions can become zinckate,selenate and
aluminate if too basic gives soluble and avaiable.
Iron is a phosfate robber . FePO4 is useless in soil !
May be INDIA has special mineral snatchers ....
We must test it !
As Russia has 50 FAGEN stat antibiotics for men and children .
My tests with SUGAR is : white FUNGI apearing over the soil !!!
We may not forget the MOST IMPORTANT is AIREATION of the soil .
With clay and rain ,air to the roots is often not enough ..
So you need help from eart wurms and perforators .
Regards
Frans
