Abstract: Manure is any excrement and urine of farmed animals and is considered a resource or waste, depending on where and how much is produced, and how it is used. It is an essential source of nutrients for plants, and it has been used for fertilizing soil and enhancing crop production since the advent of agriculture [1]. It reduces the reliance on chemical fertilizers in situations where they can be hard to find (or to afford) and in contexts like organic agriculture, where chemical fertilizers are avoided for ethical or policy reasons. Manure production worldwide is increasing [2] due to the growing demand for meat and animal-based products [3]. This trend raises concerns about the potential threat to ecosystems posed by manure, since several factors can contribute to environmental pollution hazards [4]. Manure contains high levels of nutrients like nitrogen and phosphorus. When manure is applied to soil in excessive amounts, or during periods of heavy rainfall, these nutrients can enter nearby water bodies through the processes of leaching and runoff [5]. High levels of nitrates in water bodies can lead to excessive and rapid growth of algae, causing oxygen depletion and eutrophication [6]. This process can lead to the death of fish and other aquatic organisms that depend on oxygen to survive, ultimately resulting in habitat degradation and loss of biodiversity [7]. In fact, untreated manure spread onto soils is generally considered the principal cause of eutrophication [8], [9] and of nitrate freshwater pollution from agricultural sources [10]
