Effect of Yak Dung on High-frigid Meadow Soil Nutrition in Northwestern Sichuan, China*


Abstract:
The decomposition of yak dung and its effect on soil nutrition of grassland in northwestern Sichuan, China were investigated. Soil samples were taken around (10 cm and 30 cm radius from center) dung piles on five occasions over a period of 84 days in summer. The samples were analyzed for NO3--N, NH4+-N, available K, inorganic P, total organic C (TOC), total N (TN) and total P (TP). The result showed that yak dung supplied the ecosystem there with substantial nutrients. It was estimated that the N contribution from dung was approximately 699~932 kg hm-2 and P about 110~147 kg hm-2. The total quantities of NO3--N, NH4+-N, available K and inorganic P from the initial dung largely decreased to almost none after 84 days. In the initial days (1~9 d), NO3--N, NH4+-N, available K and inorganic P in siol under the dung piles were found with a significant increase, and after two months the content of NO3--N was 8.4 times larger than that in the initial days. The contents of NH4+-N, available K and inorganic P at place 10 cm from the edge of dung piles increased significantly (P<0.05), but no significant increase was found (P>0.05) at 30 cm. Differing from the common belief, no obvious increases in TOC, TN and TP were observed in the whole experiment process.
