Apply in divided doses adjusted to the nutritional needs of plants. The amount of doses and dates of fertiliser application should be determined based on: plant nitrogen demand (unit intake x assumed crop yield per ha), plant condition, soil properties.

Use for healthy, dry plants with good turgor. Air temperature during the treatment should not exceed 20°C, and relative air humidity should be above 60%, fertilization is best carried out on cloudy days. Use coarse spraying or drag hoses.

TransportSee more

UAN (RSM) is not subject to RID / ADR / IMDG regulations concerning the transport of dangerous goods.

UAN (RSM) should be stored in closed vented containers, made of steel, plastics, or properly secured concrete. The use of non-ferrous metals or their alloys are not allowed. Pumps and pipelines which the UAN (RSM) is pushed through should be made of materials resistant to its operation, e.g., steel or plastics (polyethylene, polypropylene, PVC). The tanks should bear an inscription indicating the name of the product. The product should be protected against cooling below the crystallisation temperature during transport and storage. There is no loss of the fertiliser’s nutritional value during storage. Water that can evaporate during long-term storage should be topped up to its original state.

Precautions and hazardsSee more

H319: Causes serious eye irritation.
P264: Wash hands thoroughly after handling.
P280: Wear protective gloves/protective clothing/eye protection/face protection.
P305+P351+P338: IF IN EYES: rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing.
P337+P313: If eye irritation persists: get medical advice/attention.

This fertiliser contains urea, which can release ammonia and have an impact on air quality. Depending on local conditions, appropriate remediation measures must be taken.
