Lietesäiliöt

Lietesäiliöt, commonly known as slurry tanks or manure lagoons in English, are containment structures used on farms to store animal waste, primarily manure and urine from livestock. These structures are essential for managing agricultural byproducts, preventing environmental contamination, and facilitating nutrient recycling.

There are several types of lietesäiliöt. Above-ground tanks, often made of concrete or steel, are common, offering good containment and relatively easy access for pumping and application. Below-ground tanks, typically constructed from concrete or reinforced plastic, are also widely used, especially where space is limited or for aesthetic reasons. Lagoon systems, which are large, open ponds lined with impermeable material, are another common method for slurry storage, particularly for larger operations. The choice of lietesäiliö often depends on factors such as the scale of the operation, local regulations, climate, and available space.

The primary function of a lietesäiliö is to hold slurry temporarily before it can be applied to agricultural land as fertilizer. This storage period allows for the breakdown of organic matter and the stabilization of nutrients, making them more readily available for plant uptake. Proper management of lietesäiliöt is crucial to prevent the release of harmful substances like nitrates and ammonia into groundwater and surface water, which can lead to eutrophication and other environmental problems. They also help to control odors associated with animal waste. Regular monitoring and maintenance are vital to ensure the integrity and effectiveness of these storage systems.
