Olivine
Olivine also improves drainage and soil porosity, reducing the amount of water needed to water the plants. In addition, it helps to sequester carbon in the soil. It has been proven by the University of Wageningen that olivine promotes plant growth by 15.6%. Also spoil your plants with our olivine soil improver.

Particle size distribution of the chromite tailing sample is given in Table 1. The results show that the sizes of about 80% (by weight) of the particles are < 260 μm and 50% < 190 μm. Chemical analysis given in Table 1 indicate that as the particle size decreased, Cr 2 O 3 content increased up to 37 μm, and below that, it decreased.
