“…We suspect that this pattern is partly caused by the wind erosion and dust storms, which can be exacerbated by increasing aridity and frequently occur in higher aridity areas of northern China Yan et al, 2013;Zhang and Liu, 2010). Wind erosion favors losses of fine soil particles and consequently leads to changes of the soil texture (Feng et al, 2001;Wang et al, 2006;Yan et al, 2013). In arid and semi-arid ecosystems experiencing increasing aridity, soils become more vulnerable to wind erosion because vegetation coverage declines (Zhang and Liu, 2010).…”

Abstract. Climate factors such as aridity significantly influence soil carbon (C) and nitrogen (N) stocks in terrestrial ecosystems. Further, soil texture plays an important role in driving changes of soil C and N contents at regional scale. However, it remains uncertain whether such changes resulted from the variation of different soil particle–size factions and/or the C and N concentrations in those fractions. We examined the distribution of total C and N in both bulk soil and different soil particle–size fractions, including sand (53–2000 µm), silt (2–53 µm), and clay (< 2 µm), along a 3000 km transect in arid and semi-arid grasslands of northern China. Across the whole transect, sand content was positively and silt content was negatively correlated with increasing aridity. Carbon content in bulk soils (0–10 cm) ranged from 4.36 to 46.16 Mg C ha−1, while N content ranged from 0.22 to 4.28 Mg N ha−1 across different sampling sites on the transect. The total C and N concentrations and contents in bulk soils as well as in the three particle–size fractions tended to be negatively correlated with aridity. The concentrations and contents of total C and N in bulk soils were positively correlated with silt and clay contents and negatively correlated with sand content. Positive correlations were observed between the concentrations and contents of C or N in bulk soils and the C or N concentrations in the three soil particle–size fractions. By characterizing such a large scale aridity gradient, our results highlight that aridity would decrease soil C and N contents both by favoring increased sand content and by decreasing C and N concentrations in all the three soil fractions. These patterns thus have significant implications for understanding soil C and N sequestration under scenarios of increasing aridity in global drylands that are predicted to occur this century.

“…The combination of the dry-windy climate and the vulnerable sandy soils favors wind erosion, likely resulting in the quick spread of desertification in this region (Wang, 2002) and large-scale dust storms (Wang et al, 2006;Bagan et al, 2010).The study area, which has a topographic elevation varying from 186 to 200 m above mean sea level and is mingled with rolling sandy dunes and desert as well as flat interdune (i.e., meadow) lowlands, agricultural land, and lakes, has an average dust storm outbreak frequency of 1.92 days per year. The Horqin Sandy Land, located between the Inner Mongolian Plateau and the Northeast China Plain (Fig.…”

Abstract.A good understanding of the interrelations between land cover alteration and changes in hydrologic conditions (e.g., soil moisture) as well as soil physicochemical properties (e.g., fine soil particles and nutrients) is crucial for maintaining the fragile hydrologic and environmental conditions of semiarid land, such as the Horqin Sandy Land in China, but is lacking in existing literature. The objectives of this study were to examine: (1) spatio-temporal variations of soil moisture and physicochemical properties in semiarid land; and (2) how those variations are influenced by land cover alteration. Using the data collected in a 9.71 km 2 well-instrumented area of the Horqin Sandy Land, this study examined by visual examination and statistical analyses the spatio-temporal variations of soil moisture and physicochemical properties. The results indicated that for the study area, the soil moisture and physicochemical properties were dependent on local topography, soil texture, vegetation density, and human activity. Long-term reclamation for agriculture was found to reduce soil moisture by over 23 % and significantly (p-value < 0.05) lower the contents of soil organic matter, fine soil particles, and nutrients.

“…This area is vulnerable to wind and water erosion and to environmental degradation, due to its inherent soil and climatic characteristics (Wang et al 2006(Wang et al , 2007b and its current management practices. Continuous maize (Zea mays L.) or wheat (Triticum aestivum L.), and wheat-maize rotations, are the dominant cropping systems.…”

“…After harvest, the soil is ploughed and ploughed once again in spring before seeding. These practices contribute to a decrease in soil organic carbon (SOC) content (Yang 1996) and to soil drying and severe wind erosion in winter and early spring (Wang et al 2006). Further, recommendations for fertilizer applications are based on potential yields and do not make provision for differences in soil fertility and for other possible nutrient sources.…”

“…The effectiveness of these practices was assessed in a long-term field experiment in Shanxi province in northern China. The reduced tillage practice has been shown to be highly effective in decreasing wind erosion (Cai et al 2002;Wang et al 2006). Effects of applying organic residues and mineral fertilizer in autumn on grain yields and nitrogen (N), phosphorus (P) and potassium (K) use efficiencies have been reported in Wang et al (2007a).…”

A long-term experiment was carried out in the dryland of northern China to assess the effects of applications of maize stover, cattle manure and NP (1:0.44) fertilizer on partial nitrogen (N), phosphorus (P) and potassium (K) balances, extractable soil N (SEN), P and K, and soil organic matter (SOM) in a spring maize cropping system, under reduced tillage conditions. The experiment was set-up according to an incomplete, optimal design, with three factors at five levels and 12 treatments, including a control with two replications. Statistical analyses using multiple regression models showed that the partial N, P and K balances were strongly influenced by annual variations in the amounts of soil water at seeding (SWS) and growing season rainfall (GSR). Most treatments had positive P but negative N and K balances. Cumulative P and K balances were reflected in extractable soil P (P-Olsen) and K (exchangeable K), but the weak relationships indicated that the sorption of P and buffering of K were strong. Cumulative balances of effective organic carbon (C) were weakly related to soil organic C (SOC) content after 12 years. Negative C balances were related to decreases in SOC, but positive C balances were not translated into increases in SOC. The analysis of nutrient balances and soil fertility indices revealed that nutrient inputs in most treatments were far from balanced. It is concluded that the concepts of 'ideal soil fertility level' and 'response nutrient management' provide practical guidelines for improving nutrient management under the variable rainfall conditions of dry land areas in northern China.
