- •
Plant growth in artificial soil has derived K from potassium feldspar as well as mica.
- •
Use of mica (phlogopite) as a source of K gives response similar to KCl control.
- •
The observed growth response in both cases increases with increasing mineral dose.
- •
K content in plant tissue increases with dose, and confirms a mineral source for K.
- •
The results highlight the potential of feldspar, in syenite rock, as a source of K for tropical soils.
