“…When compared with the tested soil, the two biochar had a greatly higher content of alkaline elements, such as K and Ca (Table 1), which could be dissolved into the soil solution to remediate the acidity of the tested soil. The finding is consistent with previous studies, especially in acidic soils (Geng et al, 2022; Nguyen, Dinh, Nguyen, et al, 2022). Nevertheless, Zhang et al (2019) found in the same study that biochar addition significantly enhanced the pH of acidic soils while decreasing the pH of the black soil and having a neutral effect on the Lou soil.…”

“…Soil samples were taken from individual pots after 100 days of the experiment using a stainless steel sampler. Sampling was conducted based on the procedure by Nguyen, Dinh, Nguyen, et al (2022). The taken soil was air‐dried, ground to pass through a 2‐mm sieve, and stored until analysis.…”

“…Đất phèn được hình thành do sản phẩm bồi tụ phù sa với vật liệu sinh phèn (xác sinh vật chứa lưu huỳnhpyrite), phát triển mạnh ở môi trường đầm mặn khó thoát nước thông qua hoạt động của vi sinh vật [1]. Đất phèn có thể nhiễm mặn vì nhiều lý do khác nhau [2]. Đất phèn nhiễm mặn có thể có hàm hượng các kim loại nặng cao [3] vì loại đất này có độ chua cao và thành phần cơ giới với hàm lượng sét lớn; ngoài ra cũng có thể ô nhiễm KLN do sản phẩm trầm tích (As) hoặc chất thải công nghiệp.…”
