10-11-2019Excessive feldspar mining is becoming an alarming issue due to the untreated mine spoil. For the success in the remediation of mine spoil, selection of plant species is an important factor. Therefore being a nitrogen fixer, legumes can be an alternative and are needed to be broadcasted for the rehabilitation of mined lands.

202258Here, we report nitrogen retention in feldspar at high temperature and high pressure. Our data show that ammonium interacts with the silicate framework and forms hydrogen bonding with increasing temperature and pressure. Ammonium is more stable in feldspar than in phengite, with similar diffusion kinetics to hydrogen in feldspar.
