Dry and Hot Valley comparative study of different soil fertility in artificial
To create various types of eucalyptus forest, the role of pure forest relatively poor, particularly Acacia auriculiformis plantation, afforestation shorter than the pure stand of neem worse. But for some soil polyphenol oxidase activity decreased attention to the problem should be to prevent the accumulation of phenolic compounds due to forest soil fertility improvement. Woodland soil microbes and soil organic matter is always in close contact,[link widoczny dla zalogowanych], red gum acacia × Sumatra mixed microbial role in improving the most, reflect and create mixed,[link widoczny dla zalogowanych], in particular, is the choice of legume leaf tree species to restore degraded dry-hot valley important soil ecosystem. In addition, the plantation's soil management is to promote litter decomposition of organic matter to improve soil and understory plant diversity of the important technical measures,[link widoczny dla zalogowanych], to which attention should be paid. (4) Different woodland soil fertility analysis showed that the artificial vegetation on the dry-hot valley ecosystem restoration of degraded soil have a demonstrable effect, the integrated soil fertility index value higher than their respective control, especially in Sumatra 13 years acacia forest effect best. However, the recovery of degraded soils will take some time,[link widoczny dla zalogowanych], and vegetation should be restored again to minimize or eliminate human disturbance.
