metadata.artigo.dc.description.abstract: Rehabilitation of degraded areas by mining activities is necessary to achieve sustainable mining. For an effective revegetation, the understanding of plant growth and the nutrient requirements of native plant species, especially those with the potential to be used in the rehabilitation of mined areas such as waste piles or mine pits, is indispensable. In this study, we evaluated the growth performance, nutrient levels, and nutrient use efficiency of an endemic plant (Mimosa acutistipula var. ferrea) and ruderal shrub (Solanum crinitum) that are both found in ferriferous savannas, locally called “canga” in Carajás Mineral Province, Brazil. An experiment was conducted under greenhouse conditions using samples of three different soils (oxisol, canga soil, and iron mining waste) without and with nutrient application; additionally, an omission trial was carried out in canga soils. Fertilization increased the growth of both plant species in all substrates. Macronutrient omission reduced the growth of plants stronger than micronutrient omission, indicating that the lack of N, P, and K may especially impact the rehabilitation of areas. The growth of S. crinitum was higher than M. acutistipula var. ferrea, highlighting its preponderance in mineland rehabilitation, although concerns regarding its role as a ruderal species persist. Therefore, further research is necessary for a risk assessment of the propagation of S. crinitum within mineland restoration projects.
