“…Enzymes in the soil mainly comefrom the microbes, animals and plant roots, and the increase of their activity is an important indication of improvement in soil qualities such as physical and chemical properties physical and chemical properties (Liu et al 2014). Our data showed that the growth of seabuckthorn helped to increase the amounts of microbes in rhizosphere soil, and that the number of bacteria, fungi, actinomycetes increased obviously as compared with bare land.…”

To investigate the effects of seabuckthorn (Hippophae rhamnoides) on soil amelioration, using the space replacement method, soil physical and chemical indexes as well as the microorganism quantity and soil enzyme activities were analyzed. The results showed that: the soil bulk density of surface soil decreased and soil porosity and field capacity increased after afforestation with seabuckthorn. The plant was found to effectively reduce the soil pH, increase the soil conductivity, soil organic matters and available nutrients. Soil microorganism quantity, soil enzyme activities were both higher in 0-20 cm layer than in 20-40 cm layer. With the increase years of remediation with seabuckthorn, the quantity of soil microorganism and enzyme activities were increasing to a higher level 5 to 8 years later. Our study indicates that seabuckthorn can effectively improve soil physical and chemical properties, increase the quantity of soil microorganisms and enzyme activities, which is of great significance for the ecosystem restoration in mining areas.

“…Samples collected between adjoining dunes in site 1 showed also a higher amount of total carbohydrates per gram of soil, indicating higher C fixation capability. Liu et al (2014) found that the developmental stage of BSCs has a great influence on the enzymatic activity. A greater ability to increase C cycling was found in later-stage BSCs, when compared to early-stage BSCs.…”

“…In arid and semiarid regions, soil crusts that commonly formed once active dunes have been stabilized through re-vegetation [44]. These soil crusts perform essential ecosystem services, including enhancement of soil stability and fertility [45], protection of the soil from wind erosion [46], and fixation of C and N [47,48]. Figure 5g shows the soil crust that formed in an area of active dunes 7 years after afforestation using Populus spp.…”

Caragana microphylla, a native perennial leguminous shrub, is widely used for desertification control in China's Horqin Sandy Land. We investigated the effects of afforestation using C. microphylla in areas with fixed and active dunes on soil carbon (C) and nitrogen (N) storage in the soil total and light-fraction (LF) organic matter. Compared to the values in the control areas, soil organic carbon (SOC) storage to a depth of 100 cm increased by 88%, 74%, and 145% at 9, 15, and 31 years after shrub planting, respectively; the corresponding values were 68%, 61%, and 195% for total nitrogen (TN) storage, 109%, 199%, and 202% for LF organic carbon storage, and 203%, 337%, and 342% for LF nitrogen storage. The soil light-fraction (LF) organic matter contributed significantly to total SOC and TN storage, despite the low proportion of total soil mass accounted for by the LF dry matter. Thus, afforestation using C. microphylla was an effective way to sequester C and to restore degraded soils, but the process was slow; it would take more than 100 years to fully restore SOC storage in active dunes through afforestation with C. microphylla in the Horqin Sandy Land.
