RT null T1 What is Sustainable Potassium Management and Why Do We Need It? A1 United Nations Environment Programme, K1 nutrient K1 sustainable management K1 potassium salt K1 potassium fertiliser YR 2024 FD 2024-11 LK https://wedocs.unep.org/handle/20.500.11822/46830 UL https://wedocs.unep.org/handle/20.500.11822/46830 NO Potassium (K) is the third of the indispensable macronutrients required for all life, alongside nitrogen (N) and phosphorus (P). All three of these macronutrients play a fundamental role in our food production. However, around one-fifth of all agricultural soils face severe potassium deficiency. Whilst we know that potassium is critical to maintaining healthy ecosystems and supporting global food production, there is still more that we need to discover about potassium supply, consumption and pollution risk.
