“…3). However, in tropical dry deciduous forest, savanna and temperate pastures peak values were recorded during early spring or summer (Saratchandra et al, 1984;Singh et al, 1989) and that of subtropical humid forest where maximum value was obtained in winter season (Arunachalam and Arunachalam, 2000) may be due to the differences in quality of litter and rainfall pattern. However, low value of microbial C, N and P in winter season may be due to low activities of microorganisms and slow rate of decomposition of litter in dry and cool period.…”

Patel et al.: Seasonal and temporal variation in soil microbial biomass C, N and P in different types land uses of dry deciduous forest -377 - Abstract. The soil microbial biomass of soil is being increasing recognized as sensitive indicator of soil quality. Its knowledge is fundamental for sustainable environment management. The soil microbial biomass C, N and P were studied in four different land uses of dry tropical forest of Udaipur, Rajasthan, Western India to assess the influence of abiotic, physico-chemical variables and difference in different land uses (mixed forest, butea plantation, grassland and agricultural lands) on the seasonal variation in soil microbial biomass. Microbial biomass C, N and P were highest during rainy season and lowest during winter in all the four different land use with the exception of microbial N which was lowest in summer in mixed forest and butea plantation. Microbial biomass C and N were shown to be significantly correlated to the abiotic and physico-chemical variables of the soil, such as soil temperature, relative humidity, soil moisture, organic C, total N, clay, and pH. Present study clearly shows that land use has a significant effect on microbial biomass C, N and P in soil by altering natural soil characteristics under the same ecological conditions.

“…As discussed by Maithani et al (1996) and Barbhuiya et al (2004), lower MB values during the rainy season, when temperature and soil moisture conditions were favorable for the microbes, indicated a period of rapid mineralization in soil. Sarathchandra et al (1984) and Singh et al (1991) reported that the relatively greater nutrient demand by plants during the wet season (the peak vegetative growth period) limited the availability of nutrients to soil microbes and thereby reduced their immobilization in MB. Moreover, when soil dries out during the dry season, substrate supply might become limiting.…”

Numerous studies have documented that soil respiration and nitrogen cycling show a distinct seasonal dependence regulated by environmental factors (e.g., soil temperature and soil water content). The mechanisms controlling the seasonal dependence of these two key ecosystem processes have rarely been linked to both soil microbial community and soil environmental factors. Here, we present results on the seasonal patterns of soil respiration and gross nitrification rates in three subtropical plantations of Pinus massoniana, Castanopsis hystrix and Erythrophleum fordii over a period of 11 months. Turnover rates were measured with the Barometric Process Separation technique (BaPS). We elucidated how soil respiration and gross nitrification are controlled by the soil microbial community and by soil environmental factors. Soil respiration and gross nitrification showed strong seasonal dynamics, although no significant differences were observed among plantations. The turnover rates were the highest during the wet season and the lowest during the dry season. Microbial biomass, total phospholipid fatty acids (PLFAs), fungal PLFAs and bacterial PLFAs peaked during the dry season. Both soil respiration and gross nitrification rates were positively correlated with soil temperature and soil water content. Microbial biomass decreased with increasing turnover rates. Our findings highlight that carbon and nitrogen turnover rates were mostly controlled by soil temperature and soil water content.

“…After bulking and screening «4 mm) to remove plant material, the soils were stored in polythene bags at -20°C. Some microbiological and biochemical characteristics of these soils have been reported by Sarathchandra et al (1984). Organic C, total N, pH, total P, organic P and NaHCO -extractable P were determined on air -dried and sie~ed «2 mm) subsamples as described by Perrott & Sarathchandra (1987).…”

A fumigation-extraction method was used to determine the phosphorus (P) content of the microbial biomass in a range of New Zealand highproducing pastoml soils. Despite high levels of extractable P in some soils, the increase as a result of fumigation was easily measured. Microbial P in the top 75 mm of the soils ranged from 10.5 to 57.4 kg P/ha (mean 31.8 kg P/ha) and could amount to several times that in the standing crop of the aboveground pasture. Microbial P was .correl~ted wi~ both bicarbonate-extractable organIC and morganic P. The correlations with extractable organic P were better than with extractable inorganic P, supporting the suggestion that NaHC0 3 solutions extract a labile fraction of organic P from soils.
