Silicon, a micronutrient, positively influences plant nutrient availability and drought resistance. Current supply chains mostly rely on traditional, non-circular economy sources, causing downsides in terms of ecological sustainability. K+S, a global leader in plant nutrition solutions, has joined forces with VCG.AIfrom RootCamp batch #6, to use the AI-driven value chain generator platform from VCG to find new, sustainable sources of silicon for plant nutrition. These silicon sources could be used as a value-adding additive to standard K+S fertilisers.
