Agricultural Science and Fertilization

The results of an ongoing study of soil improvement using pyrite-rich waste from the Neves-Corvo copper mine as an amendment, are reported for an area in southern Portugal. The application of pyrite to the calcareous soils resulted in the increased availability of certain trace elements, an increase in nutritive parameters, and an increase in dry matter production. This application does not appear to lead to pollution problems in surface waters or toxicological problems in grazing animals.
