Sentence examples for mining soils from inspiring English sources

Results from soil samples under different anthropogenic perturbations showed significant (P < 0.001) differences in CO2 contents (mg h− 1 100 g− 1) produced by agricultural (3.3) and mining soils (1.3).

Thlaspi was unable to survive in mining soils containing either a level higher than 11 000 mg kg−1 of Pb and 4500 mg kg−1 of Zn, while engineered plants yielded an average of 0.5 kg per plant.

Two different amendments, an iron-rich water treatment residue (Fe-WTR), a municipal solid waste compost (MSW-C) and their combination (Fe-WTR + MSW-C) were added at different rates (from 2 to 4% w/w) to three mining soils (S1, S2, S3) mainly polluted with As (from 371 to 22,661 mg·kg− 1 d.w).

In highly polluted soils like mining soils, where the removal of metals by phytoextraction using hyperaccumulator plants is not efficient due to the slowness of the process, the best adapted method is phytostabilization [ 3].

If the loose layer is significantly thick, it is inevitable that pressure consolidation of a water-bearing loose layer or deformation of the soil body will cause additional stress in the mining soil body, and dissipation of the excess pore water pressure will result in consolidation.

Many of the grass and legume species commonly grown on non-mined pastures also can be established on mine soils (Ditsch and Collins 2000).

Overall, low nutrient availability in mine soils translates into generally lower foliar nutrient concentrations in trees growing on mine soils.
