Slurry is a mixture of organic material (either cow feces and urine, or shredded plant matter) that has been allowed to ferment in an open-air tank. It does, however, still require quite a bit of work to use. Due to the relatively-high capacity of the fertilizing machines that use it, as well as some options unique to this fertilizer types, it is certainly one of the better choices for fertilization in the game. Though essentially free, Slurry is only abundant if you're producing massive quantities of Silage. Once created, Slurry is absolutely free of charge. Slurry accumulates slowly into a special tank near where it was created, and can be taken from that tank by a variety of Slurry-related equipment. Slurry can be generated in two different ways: It can be generated as a byproduct of Cow husbandry, as long as the Cows are fed on any substance Or, it can be generated as a byproduct of selling Silage at the Biogas Plant.

It is spread by Slurry Spreaders such as the Marshall ST 1800. It is just as effective at this as any other Fertilizer.

Slurry can be sprayed on a field in order to increase its Crop yield. Slurry is one of several types of Fertilizers in Farming Simulator 15.
