This traditional practice continues, but an increase in phosphorus mining throughout the twentieth century contributed to steadily rising agricultural yields.
Tungsten and phosphorus are mined near Kunming.
Of the three essential macro nutrient fertilizers, nitrogen is relatively plentiful and recoverable, but we're running out of potassium and phosphorus, finite mined resources that are "necessary for all life".
Similar significant differences between pH, EC, and total phosphorus at Oaky Creek mine (Table 3) suggest that there are consistent differences between replaced soils and those found at selected reference sites.
In the book, you write about visiting a plant that mines phosphorus, an ingredient used in explosives, matches and artillery shells.
This value of P observed in the surface water around the Ijeshaland gold mines was within the recommended phosphorus value of 0.03 mg L−1 in surface water (Canadian Ministry of the Environment and Energy 1994).
Eight of the nine species at Whiteman Park were lower in phosphorus than the same species on the mines; Huntly values were highest (Table 3).
