Description of key information
According to “ANNEX IX- STANDARD INFORMATION REQUIREMENTS FOR SUBSTANCES MANUFACTURED OR IMPORTED IN QUANTITIES OF 100 TONNES OR MORE , study for effects on terrestrial organisms and plants need not be conducted if:
- These studies do not need to be conducted if direct and indirect exposure of the soil compartment is unlikely.
Potassium is one of the three major nutrients for plants. The potassium requirement for optimal plant growth is in the range 2-5 % of the plant dry weight of vegetative parts.
Potassium in plants is important for the osmotic and ionic regulation, plays a key role in the water
homeostasis, and is closely connected with processes involved in the protein synthesis. In higher plants, potassium affects photosynthesis at various levels.
Key value for chemical safety assessment
