Easy Storage, Filling and Transport

Transport and Storage of Nitrogen Fertilisers.

UOur PIAGRAN® 46, ALZON® 46, and PIAMON® 33-S ertilisers are loose products that can be effectively transported. It is important to ensure that cargo vehicles and storage areas are clean and dry. Avoid mixing with other fertilisersand protect your fertiliser from precipitation and humidity. In warehouses, cover the fertiliser with foil and keep the gates closed. To prevent abrasion and hardening, please do not use pneumatic or jet conveyor belts. Change the discharge point regularly and don't let the product fall further than five meters. Under specific circumstances, fertilisers can cause metal and concrete to corrode. Protect your equipment through proper coating. Make sure that no fertiliser can seep into sewage works, bodies of water or groundwater, since urea is a water-hazardous substance (German Water Hazard Class 1). All types of heat sources must only be run at an appropriate distance. Lastly, keep adjacent areas and roads clean, as spilled granulate can cause slipping.

We produce our solid nitrogen fertiliser for you.

Using state-of-the-art filling and packaging equipment, we package our solid fertilisers PIAGRAN® 46, PIAMON® 33-S und ALZON® 46 as well as prilled urea fertiliser in the following packaging types:

  • Big Bags at 500 kg and 1,000 kg on Euro-/chemical pallets
  • Bags (PE) at 25 kg and 50 kg auf Euro-/chemical pallets
  • In 900- or 1,000-kg containers

Proper Transport and Storage of SKWP fertilisers.

In this brochure, we give recommendations for the proper handling of our fertilisers, in particular about the cost effective and secure storage of liquid fertiliser. All information and data matche our current state of knowledge and may be subject to change. It does not constitute a legally binding guarantee. You are, however, required to follow legal regulations. Our fertilisers are classified as water-hazardous substances in the German water hazard classification (WHC 1) and must not come into contact with sewage works, bodies of water or groundwater. The handling of equipment for the storage, filling or transportation of water-hazardous substances is regulated by the German Wasserhaushaltsgesetz (Water Resources Act WHG), the Wassergesetze (Water Acts - WG) at state level and the regulations of the VAwS-Verordnung über Anlagen zum Umgang mit wassergefährdenden Stoffen (Regulation on Facilities that Handle Water-Hazardous Substances). During storage, please take into account the current construction and water legal regulations and check with local authorities regarding authorisation provisions. Our liquid fertilisers are subject to the Ordinance on Hazardous Substances on Fertilisers Containing Ammonium Nitrate, Group D I. Store liquid fertiliser in a clean place and prevent its drying. In temperatures under –15 °C the fertiliser will form crystals which will again dissolve in warmer temperatures. Thorough mixing or pumping will make the fertiliser fully useable again. Our liquid fertiliser can be combined with water at any ratio. Prevent layering by mixing the solution thoroughly. On this website, you will find recommendations regarding the transportation and storage of granulated fertiliser and the transportation of liquid fertilisers. The following pages include information on the storage of our liquid fertilisers, basic requirements for storage facilities, your responsibilities as a user and necessary technical aspects. If you have any further questions, especially concerning the planning your own liquid storage facility, we would be happy to provide personal assistance.

Safe Transportation of Liquid Fertilisers

SKW liquid fertilisers can be transported easily in tanker lorries on highways, in tank wagons via rail, or in tankers on water. The cargo container must be clean and most importantly, airtight. The respective weight restrictions must be taken into account. Tanker lorries must not be used as storage facilities. For road transport, the traffic signs 269 and 354 of the German Road Traffic Act must be followed.

Basic Storage Requirements According to the Water Resources Act (WHG)

  • Storage facilities must be built and maintained so that liquid fertiliser cannot seep out. They must be airtight, stable and highly resistant to common mechanical, thermal and chemical influence. The use of single-shell underground storage facilities is prohibited.
  • Leakages in any part of facilities in which water-hazardous substances are stored must be quickly and properly detectable.
  • Liquid fertiliser leakages must be quickly and properly detected, utilised or disposed of. Regulations require facilities to have an airtight and durable back-up container to collect leakage, unless the facility is double-walled and equipped with a leak detection device. When no other security methods are used (e.g., a pump leading leaked fertiliser back into the tank), the back-up container must be fit to hold all the content of the storage unit.
  • Substances which may have been polluted by water-hazardous materials must be contained and properly utilised or disposed of.
  • Storage facilities must not have drains.

Legal Requirements for Users According to the WHG.

  • Operating instructions must be compiled, including surveillance, maintenance and alarm plans. These instructions are to be used at least once a year to instruct employees at work about the dangers resulting from handling water-hazardous substances.
  • EAccidents in which liquid fertiliser leaks must be reported, even when such events are not confirmed.
  • EStorage facilities must be equipped with clear warning labels according to the Hazardous Goods Ordinance and the WHG, clearly naming the water-hazardous substance in storage. In some German states, the operating pressure also has to be indicated.
  • EIn the facilities, the officially recognized information sheet „Betriebs- und Verhaltensvorschriften beim Umgang mit wassergefährdenden Stoffen“ must be displayed permanently in a visible location. Employees must be made aware of the content.
  • EFacility managers are required to cease operations in the event of an accident if the endangering or contamination of a body of water cannot be prevented by other means. If a facility is to be officially inspected, the facility manager has to present the inspector with all official documents from authorities and documents from the manufacturer prior to the inspection.
