gjødseltank

A gjødseltank, or slurry tank, is a storage container for liquid manure. These tanks are crucial in modern agriculture for managing animal waste, primarily from livestock operations like dairy farms and pig farms. The primary purpose of a gjødseltank is to hold manure before it is spread on fields as fertilizer. This storage allows farmers to manage the timing of application, ensuring it aligns with crop needs and environmental regulations.

Gjødseltanker come in various sizes and materials, with common options including concrete, steel, and fiberglass. They can be built above ground or below ground. Above-ground tanks are often cylindrical and made of steel or fiberglass, while below-ground tanks are typically constructed of concrete or specially designed plastic. The choice of material and design depends on factors such as the volume of slurry to be stored, local climate conditions, and budget.

Properly managing a gjødseltank is important for environmental protection. Manure contains nutrients like nitrogen and phosphorus, which can be beneficial for soil fertility. However, if not stored and applied correctly, these nutrients can leach into groundwater or run off into surface water, causing pollution and eutrophication. Modern gjødseltanker often incorporate features to minimize emissions of gases like ammonia and methane, which contribute to air pollution and climate change. Some tanks are equipped with covers or agitators to homogenize the contents and facilitate even spreading.
