Olivine Weathering in Soil, and Its Effects on Growth and …
Olivine increased soil water pH and alkalinity, plant uptake of Mg, Si and Ni, as well as bioavailability of Mg and Ni in soil. Olivine clearly suppressed Ca uptake which is attributed to competition by Mg. All these effects increased with higher olivine doses. There was a slight negative effect on P content in plant biomass at high olivine doses.

ALEX STREKEISEN-Olivine-
Olivine - (Fe,Mg) 2 SiO 4 Olivines are an important rock-forming mineral group. Magnesium-rich olivines are abundant in low-silica mafic and ultramafic igneous rocks and are believed to be the most abundant constituent of the Earth's upper mantle. Olivine also occurs in high-temperature metamorphic rocks, lunar basalts, and some meteorites.
