“…However, our result that the land-use conversion had little effect on bacterial biomass does not support other studies in the literature. For example, Li et al [13] found that soil bacterial biomass significantly decreased 5 years after land-use conversion from paddy to vegetable field in Jiangsu Province. In this study, we found that the most significant factor affecting the structure of soil microbial communities was soil water content (Fig.…”

“…Agricultural management practices, such as cropping rotation, irrigation, and fertilization are known to have significant effects on microbial community structure in soils [5e9], which thereby influence the overall agroecosystem functions [10e12]. Land-use conversion, such as the conversion of rice paddies to uplands or vice versa, can significantly affect soil microbial communities [13,14]. Bossio et al [15] found that flooded paddy soils had higher abundance of branched fatty acids, lower abundance of monounsaturated fatty acids, and lower abundance of fungi and actinomycetes than upland tomato fields.…”

a b s t r a c tA short-term experiment was carried out in southern China to investigate the effects of land-use conversion from rice paddies to vegetable fields and fertilization on soil microbial community structure by analyzing soil phospholipid fatty acid (PLFA) profiles. A split-plot design with four replicates was adopted, in which land use (paddy and vegetable field) was the first-level treatment and fertilization (conventional fertilization and no fertilization) was nested as the second level. Our results showed that both land-use conversion and fertilization had significant effects on microbial community structure. After 2 years of land-use conversion, the total amount of PLFAs were 3.54 and 2.97 nmol g À1 for fertilized (VeF) and unfertilized (VeNF) vegetable fields, respectively, and 3.19 and 2.32 nmol g À1 for fertilized (R eF) and unfertilized (ReNF) rice paddies, respectively. Soil fungal PLFAs were 1.04 and 0.87 nmol g À1 for VeF and VeNF, respectively, which were significantly increased by 13.9 and 11.4 times compared with those of ReF and ReNF, respectively. The ratio of fungal to bacterial PLFAs significantly increased in vegetable fields compared with rice paddies. No significant differences were found in the total, bacterial, and actinomycetic PLFAs between vegetable fields and rice paddies. The application of fertilizer significantly increased the amount of total PLFAs and bacterial PLFAs. With land-use conversion and fertilization, soil physicochemical properties also changed, and microbial community structure showed a significant relationship with soil water content, NH 4 þ -N, and pH, which explained the land-use conversion and fertilization effects on soil microbial community composition.

“…The functional diversity parameters of the microbial communities were calculated as described by Garland and Mills (1991) using the AWCD values from the 96 h time point, as these values represented approxi-mately 50% saturation where the highest differentiation was expected (Garland and Mills, 1991;Li et al, 2007).…”

“…Therefore, they have been widely applied in agricultural water saving and ecological recovery and could improve the environment for plant growth under limited water supply [6]. Soil microorganisms involve in material cycles and energy transformation under different land uses [7]. As a cyclic soil nutrient base, they facilitate decomposition of soil organic matter, formation of humus and transformation and cycling of soil nutrients, thus known as an important nutrient source for plant growth.…”

Abstract. Effects of different years of Polyacrylamide (PAM) application on oat growth, soil microbial biomass and moisture content in semi-arid regions were studied through a field experiment from 2011 to 2015. The experiment consisted of total of 5 treatments and a control. These were: Conventional tillage (CK), (1) M1: PAM 2011, (2) M2: PAM 2011 and 2012, (3) M3: PAM 2011, 2012, (4) M4: PAM 2011, 2012, (4) M5: PAM 2011, 20122015and 2015. The results showed that with increasing PAM and the time interval, the oat seedling soil moisture content (SMC), microbial biomass carbon (SMBC), microbial biomass nitrogen (SMBN), and microbial biomass phosphorus (SMBP) had a rising trend. Compared with the control, the treatments administered continuously for five years; SMC of 0-60 cm soil layer was affected the mostly. Differences of test groups decreased with the increase of soil layer. At a depth of 0-60 cm soil, soil moisture increased by 25.91-78.51% in M5. SMBC increased by 21.39-69.49% in M4, SMBN increased by 34.58-139.02% in M5 and SMBP increased by 44.58-83.38% in M5. Meanwhile, aboveground fresh weight increased by 196.67-232.88% in M5 as well as dry weight increased by 182.05-224.23% in M5, respectively after stable emergence. The effects of applying PAM on micro ecological with differences time interval have an effect on soil microbial life, the results point out the following superiority order: 5 years>4 years>3 years>2 years >1 year. However, there was significant improvement observed in plowing layer, with continuous application of PAM at 0-20 cm depth, SMC has significant positive correlations with fresh biomass and all three SMB variables. We recommend application of PAM could improve soil moisture content and then influence microbial biomass and further plant growth; M5 treatment which is more suitable for the rainfed farmland. Farmers can be recommended to use PAM to improve soil qualities and crop production in loess hilly-gully region of China.
