Does the plant absorb the effective silicon in silicon calcium fertilizer or absorb silica?
I don't really know, or would you wait for the great God to answer? I'm not sure which SiO2 and the effective silicon can form ions in the soil. Plant absorption of elements is carried out by ion exchange, and can not directly absorb single elements, I think so.
Plants can absorb Portland, silica is a representation of numbers, how many can convert silicate; effective silicon refers to that part of the silicate can be absorbed by plants (the number of Portland and then converted into pure silicon).
Silica is not absorbed. Elemental silicon is not directly absorbed by plants
