Humus fractions and optical property of humic acid on alkalized meadow soil were analyzed during different age at the 15 years long-term organic fertilization in Yongle town,Zhaozhou county,Heilongjiang province.Through the combination of agriculture and animal husbandry,long-term organic fertilization on saline soil,soil total organic carbon content and humic acid,humin content in humus were increased by 116.3%,120.7% and 259.2% with years increased significantly,but it had little effect on… CONTINUE READING
