“…The response of soil microbial functions to different temperatures can be mediated by a combination of enzyme response within microbial communities and changes in the microbial taxa abundances adapted to different temperatures [54,55]. The response mechanisms of soil microbial communities to changing of temperature include acclimatization, genetic adaptation, and sorting of species [56,57]. Contrary to our first hypothesis, we found that warming significantly decreased bacterial 16S rRNA gene copy numbers in shallow soil.…”

“…Contrary to our first hypothesis, we found that warming significantly decreased bacterial 16S rRNA gene copy numbers in shallow soil. Wang et al [56] and Hayden et al [58] also observed that bacterial abundance decreased in response to increasing temperature. Aillson et al [25] found that bacterial abundance declined by over 50% in boreal forest soils under warming.…”

Global warming is likely to influence the soil microorganisms and enzyme activity and alter the carbon and nitrogen balance of peatland ecosystems. To investigate the difference in sensitivities of carbon and nitrogen cycling microorganisms and enzyme activity to warming, we conducted three-year warming experiments in a boreal peatland. Our findings demonstrated that both mcrA and nirS gene abundance in shallow soil and deep soil exhibited insensitivity to warming, while shallow soil archaea 16S rRNA gene and amoA gene abundance in both shallow soil and deep soil increased under warming. Soil pmoA gene abundance of both layers, bacterial 16S rRNA gene abundance in shallow soil, and nirK gene abundance in deep soil decreased due to warming. The decreases of these gene abundances would be a result of losing labile substrates because of the competitive interactions between aboveground plants and underground soil microorganisms. Experimental warming inhibited β-glucosidase activity in two soil layers and invertase activity in deep soil, while it stimulated acid phosphatase activity in shallow soil. Both temperature and labile substrates regulate the responses of soil microbial abundances and enzyme activities to warming and affect the coupling relationships of carbon and nitrogen. This study provides a potential microbial mechanism controlling carbon and nitrogen cycling in peatland under climate warming.

“…The faster degradation of myclobutanil at higher temperature could be mainly due to a higher microbial activity. Wang et al (2014) found that high temperature significantly increased fungal abundance from 86 to 274% under 55% water holding capacity in a tea orchard soil. The volatilization in high temperature may have an insignificant effect on dissipation of myclobutanil, for myclobutanil is nonvolatile and has low mobility in soil.…”

“…Tea (Camellia sinensis) is cultivated widely on acid red soils in the tropical and subtropical zones in China as an important economic crop (Wang et al, 2014) and also in more than 50 countries in the world with an annual production of approximately 4.7 million tons (Fang et al, 2014). Xue et al (2006) reported that the pH value of tea orchard soil gradually decreases, and soil organic matter, soil N and P contents incease with the increase of cultivating ages.…”

Article Info Received : 17.06.2016 Accepted : 14.10.2016 Persistence of the fungicide myclobutanil in three tea orchard soils with different cultivating ages, neighboring wasteland and forest soils, and its influence on microbial activities in 2-and 50-year-oldtea orchard soils at three rates were studied in the laboratory. Dissipation data fitted well to first-order kinetic equation, except for sterilized treatments, in which neglected dissipation of myclobutanil was observed. At 25 o C, the dissipation half-lives (DT50) at level of 1mg kg -1 were in the range of 15.07-69.32 days under non-flooded condition, significantly lower than flooded condition (p < 0.05), indicating that dissipation of myclobutanil was mainly driven by soil microorganisms under aerobic condition. Dissipation rate was significantly increased at 40 o C compared to those at 4 o C and 25 o C for all five soils (p < 0.05). Under all incubation conditions, DT50 were lowest in 50-year-old tea orchard soil (p < 0.01). Correlation analysis between DT50 in tea orchard soils and soil properties showed that soil microbial biomass carbon was negatively correlated with DT50 under 25 o C and 60% water holding capacity (p < 0.05). In general, soil microbial biomass carbon and dehydrogenase activity decreased as the concentration of myclobutanil and incubation time increased except 0.1 mg kg -1 spiked soils, in which soil dehydrogenase activity was stimulated after 10 days incubation.

“…Microorganisms responsible of soil organic matter degradation are influenced by changes in the soil environment; low temperature and anaerobic conditions restrict microorganism activity and abundance. A decrease in soil temperature, resulting from waterlogging, produces a proportional decrease in organic matter decomposition rates [26,27].…”

A review on agricultural effects of restricted soil drainage conditions is presented, related to soil physical, chemical and biological properties, soil water availability to crops and its effects on crop development and yield, soil salinization hazards, and the differences on drainage design main objectives in soils under tropical and semi-arid water regime conditions. The extent and relative importance of restricted drainage conditions in Agriculture, due to poor irrigation management is discussed, and comprehensive studies for efficient drainage design and operation required are outlined, as related to data gathering, revision and analysis about geology, soil science, topography, wells, underground water dynamics under field conditions, the amount, intensity and frequency of precipitations, superficial flow over the area to be drained, climatic characteristics, irrigation management and the phenology of crop productive development stages. These studies enable determining areas affected by drainage restrictions, as well as defining the optimal drainage net design and performance, in order to sustain soil conditions suitable to crops development.
