Accumulation patterns of Cu and Ni for Indigofera melanadenia and Tephrosia longipes plant species growing in Cu–Ni mining area in Botswana

“…Indicators are plants that reflect metal levels in the soil with a constant plant to soil metal concentration ratio (Baker et al, 1994;Reeves and Baker, 2000). They are useful for biogeochemical exploration techniques as they can indicate a specific mineralization (Lintern et al, 1997;Brummer and Woodward, 1999;Pujari and Shrivastava, 2001).…”
