Nickel Farming
Nickel is toxic to most plants and will kill most vegetation, but plants known as nickel hyperaccumulators thrive in nickel-rich soil and ooze blue-green nickel-concentrated sap. At up to 25% nickel, the sap is far more concentrated than rock-based nickel ores typically used at smelters, which might have nickel concentrations as low as 1.2%.
