“…(Devi and Yadava 2006). It was higher in summer than in spring and autumn, being consistent with a previous forest study (Yang et al 2010). However, the increase of microbial activity or biomass cycling may lead to an increase in soil respiration (Leita et al 1999).…”

“…With a delay of about 3 months, a trend towards lower microbial biomass C was observed from summer to autumn (Figure 1a), and then turned to increase till next summer. Seasonal variations of microbial biomass reflect the degree of immobilization-mineralization of soil C (Yang et al 2010). A decrease in microbial biomass can result in mineralization of nutrients, whereas an increase may relate to the immobilization of nutrients (McGill et al 1986).…”

Soil samples were collected at both jointing and maturing stages of maize and wheat to compare the effects of 4-year no-tillage (NT) and conventional tillage (CT) on seasonal variations of microbial biomass carbon (C), metabolic quotient, and invertase activity in a sandy loam soil in North China. Soil invertase activity significantly increased (P < 0.05) from summer to spring of the next year and then significantly decreased (P < 0.05) from spring to summer. With a delay of about 3 months, soil microbial biomass C and basal respiration altered in a similar pattern, while microbial metabolic quotient changed on the contrary. Compared with CT, the NT practice significantly increased (P < 0.05) soil organic C content, and tended to result in higher soil microbial biomass C and invertase activity, as well as lower soil microbial metabolic quotient, especially at the jointing stage of maize. Our results indicated that NT might play an important role in the improvement of soil microbial efficiency, especially at the maize seedling season.

“…Prior to the fire, microbial community abundance in the forest floor was most closely (positively) related to forest floor N concentration, while that in the mineral soil was positively associated with concentrations of C and N (presumably reflecting organic matter content). Relationships between soil organic matter or C content and microbial community structure have been reported in forest soils (Yang et al, 2010;Brockett et al, 2012), grassland soils (Grayston et al, 2004;Katsalirou et al, 2010) and agricultural soils (Yao et al, 2006;Franklin and Mills, 2009). Declines in C content with depth have also been related to changes in soil microbial communities in forest soils (Leckie, 2005;Grayston and Prescott, 2005).…”

“…Therefore, the MBC/SOC ratio provides a measure of organic matter dynamics (Anderson and Domsch 1989;Carter 1991). The higher MBC/SOC ratio also indicates that a higher amount of organic matter is mineralized (Sparling 1992;Yang et al 2009), which is interpreted as substrate available and the portion of total SOC immobilized in microbial cells (Yang et al 2010). Highly positive correlations between respiration rate and MBC and MBN contents were noted (Table 5).…”

Continuous cultivation has been known to decrease soil organic matter content. Application of organic matter to cultivated soil is an important practice from the point of view of maintaining an adequate amount of soil organic matter. Soil organic matter content significantly affects soil microbial activity, which is an important index of soil quality. In this study, a field experiment was conducted to examine the long-term effects of different kinds of organic matter in combination with inorganic nitrogen (N) fertilizer on chemical and biological properties of soils. There were seven treatments, namely (1) The results showed that compared with CK and Chem-N treatments, applications of compost and peat increased soil organic carbon (SOC) content and altered microbial activities and microbial community structure. However, application of green manure for 12 years had no effect on SOC content. Both microbial activities and PLFA profiles were clearly dependent on the characteristics of the applied organic amendments. In summary, a peat application led to the highest increase in SOC content compared to compost and green manure; however, compost-treated soil had a higher microbial population and higher microbial and enzyme activities, while the effects of both green manure and chemical N fertilizer on soil properties were similar.
