Tóm tắt

Một nghiên cứu thí nghiệm dạng cột đã được thiết lập với các mẫu than bùn từ bốn địa điểm ở miền nam và trung Phần Lan và hai địa điểm từ các vùng than bùn rộng ở phía tây Ireland để đánh giá các yếu tố góp phần vào việc chuyển giao P, N, Fe và carbon hữu cơ hòa tan (DOC) tới các dòng nước nhận từ các vùng đất than bùn đã được phục hồi và đã thoát nước cho lâm nghiệp. Nghiên cứu cho thấy rằng sự giải phóng DOC và Fe từ các khu vực than bùn đã được tái ướt có khả năng bị chi phối bởi lượng Fe trong than bùn và mức độ giảm Fe khi tái ướt. Ngược lại với giả thuyết khác của chúng tôi liên quan đến DOC, tính dễ phân hủy cao của vật chất hữu cơ không liên quan đến sự giải phóng DOC cao. Sự giải phóng nitrat đã được tìm thấy hầu như ngừng lại cùng với sự thiếu hụt oxy, nhưng sự giải phóng amoni từ một địa điểm có tiềm năng nitrat hóa cao trước khi ướt là khá lớn. Sự giải phóng P từ than bùn kỵ khí rất phức tạp theo nghĩa là nó dường như bị kiểm soát bởi nhiều yếu tố đồng thời. Tại các địa điểm nghèo dinh dưỡng, sự giải phóng P đã tăng lên sau khi tái ướt, có lẽ là do nồng độ P trong than bùn dễ hòa tan cao và nồng độ Al và Fe thấp, dẫn đến sự gia tăng di động P kỵ khí, nhưng khả năng tái hấp thụ P bị di động lại bị giới hạn. Trong số ba địa điểm giàu dinh dưỡng, không có sự giải phóng P nào xảy ra khi tái ướt hoặc có sự giải phóng P cao hơn so với các địa điểm nghèo dinh dưỡng. Rủi ro thấp về sự giải phóng P sau khi tái ướt ở các địa điểm giàu dinh dưỡng đã được liên kết với hàm lượng P dễ hòa tan thấp trong than bùn và tỉ lệ mol Fe/P cao.
