TY - JOUR T1 - The Impact of Soil Available Phosphorus on the AM Fungi and the Organic Acids Exudation at Different Patches in Northern Steppe of China AU - Zhang, Yingjun AU - Zhou, Hanshu AU - Yang, Gaowen JO - Journal of Animal and Veterinary Advances VL - 11 IS - 24 SP - 4553 EP - 4558 PY - 2012 DA - 2001/08/19 SN - 1680-5593 DO - javaa.2012.4553.4558 UR - https://makhillpublications.co/view-article.php?doi=javaa.2012.4553.4558 KW - Phosphorus KW -arbuscular mycorrhizal fungi KW -organic acid KW -rhizosphere KW -grassland patches AB - The research is conducted at a degraded steppe in Hebei province, China. Researchers took four sample areas which are dominated by fringed sagebrush (Artemisia frigida), narrowleaf stellera (Stellera chamaejasme), shining speargrass (Achnatherum splendens), white swordflag (Iris lactea), respectively. Phosphorus (P) was applied at four levels (0, 5, 10 and 15 mg kg-1 soil) in each sample area. The AM fungi colonization and the organic acid exudation in the rhizosphere were affected by the concentration of soil available phosphorus. These results suggested that the difference of soil P content is probably the cause of the appearance of four patches. ER -
