Date of the pasture cattle manure pollution research
Description
Results indicated that FCM contained high N and total organic carbon compared to DCM. Leaching experiments revealed the FCM released more N and P to pastoral water than those from DCM. However, soil adsorption and desorption experiments demonstrated that soil in pastoral areas would reserve N and P from CM, reducing the contribution to water pollution. Furthermore, the predominant organisms in FCM such as Proteobacteria and Bacteroidota would inhibit the release of N and P from CM. The quantified pollution load from CM to water quality deterioration revealed that, the contribution of N and P inputs was generally below 1%, indicating that CM is not the major driving factor for water quality decline. Therefore, although CM contributes pollution load, its impact on water quality evolution is limited compared to other anthropogenic factors (local industry and agriculture). The study provides new insight for integrated management strategies to protect the ecological health in pasture.
