Understanding the mobility of potential nutrients in rock mining by- products: An opportunity for more sustainable agriculture and mining

Adilson Celimar Dalmora, Claudete Gindri Ramos, Leandro Gomez Plata, Marcondes Lima da Costa, Rubens Muller Kautzmann, Luis Felipe Silva Oliveira Abstract The increase in demand for highly soluble fertilizers brings a global sustainability concern. Alternative sources for traditional fertilization are therefore needed. Rock powder use has been proposed as an alternative approach to soil remineralization. However, research on the agricultural potential of minerals and rocks as alternative sources of nutrients is limited to changes in soil chemical attributes or effects on crop yield. In this work, we report an experimental study addressing the ...
