“…Manley et al (2000) reported that woody vegetation is an important parameter influencing the availability soil nutrient content and composition of soil microbes in sand dune areas. The same holds true for the present observation as well because the fungal numbers of the study sites are strongly correlated with ecological conditions (temperature and moisture) as well as to standing undergrowth (Panda, 2010a;Mohanty and Panda, 2011).…”

“…They utilize the simplest carbohydrates and consequently play an imperative role in initiation of cellulose decomposition in a soil ecosystem (Mohanty and Panda, 1998;Panda, 2010b). Considerable works in India have been reported on fungi of forest soils (Behera et al, 1991;Mohanty and Panda, 1991;Mohanty and Panda, 1994a, 1994bManoharchary et al, 2005;Manoharchary et al, 2008;Nilima et al, 2007;Mohanty and Panda, 2011)and it has been concluded that soil microfungi show ecological and geoclimatic specificity with response to environmental parameters. However, it is disappointing and also surprising that despite a long period of research, reports on coastal sand dunes are limited in comparison to forest soils.…”

Variation and diversity of soil microfungal community structure in general and sugar fungi in particular were studied in coastal sand dunes of Odisha, using standard procedures. Although the two sites were located on the same soil, the effects of plantation were reflected by changes on the physico-chemical properties of soils. Of the fungi isolated from these soils Aspergillus, Penicillium and Trichoderma were found dominant in all the soil profile. The greatest dissimilarity was found between the species of Mucorales (sugar fungi) particularly Absidia, Mucor and Rhizopus in two layers of both the soils. However, Rhizopusconhii and Thamilidium species preferred the barren sand dune. Diversity index analysis indicated that the sugar fungi were changing from soil with Anacardium plantation to that of virgin sand dunes. It can be concluded that the plantation significantly influences the growth and diversity soil fungi. Appropriate measure is warranted for the protection of the existing forest cover and natural biodiversity of the sand dunes through proper management strategies. Thus, we recommend afforestation of Anacardiumoccidentale in virgin sand dunes as a multipurpose tree which will have favourable environmental effects and will be beneficial in providing some economic value to villagers.

“…Therefore, the effect of soil temperature may have been influenced indirectly, since soil moisture content has its own effect on soil temperature (Rey et al, 2002). At high soil temperatures, soil moisture becomes a limiting factor for respiration in tropical soils (Mohantya and Panda, 2011). In our experiments soil temperatures ranged from 22 to 47 °C which are typical for tropical regions, while the most followed by different letters, upper case letters in the row and lower case letters in the column, differ between themselves by the t test (LSD = least significant difference) at the 5 % probability level.…”

In addition to improving sustainability in cropping systems, the use of a spring and winter crop rotation system may be a viable option for mitigating soil CO 2 emissions (ECO 2 ). This study aimed to determine short-term ECO 2 as affected by crop rotations and soil management over one soybean cycle in two no-till experiments, and to assess the soybean yields with the lowest ECO 2 . Two experiments were carried out in fall-winter as follows: i) triticale and sunflower were grown in Typic Rhodudalf (TR), and ii) ruzigrass, grain sorghum, and ruzigrass + grain sorghum were grown in Rhodic Hapludox (RH). In the spring, pearl millet, sunn hemp, and forage sorghum were grown in both experiments. In addition, in TR a fallow treatment was also applied in the spring. Soybean was grown every year in the summer, and ECO 2 were recorded during the growing period. The average ECO 2 was 0.58 and 0.84 g m 2 h −1 with accumulated ECO 2 of 5,268and 7,813 kg ha -1 C-CO 2 in TR and RH, respectively. Sunn hemp, when compared to pearl millet, resulted in lower ECO 2 by up to 12 % and an increase in soybean yield of 9% in TR. In RH, under the winter crop Ruzigrazz+Sorghum, ECO 2 were lower by 17%, although with the same soybean yield. Soil moisture and N content of crop residues are the main drivers of ECO 2 and soil clay content seems to play an important role in ECO 2 that is worthy of further studies. In conclusion, sunn hemp in crop rotation may be utilized to mitigate ECO 2 and improve soybean yield.

“…2). During the night times, low temperatures and high relative humidity at the study site (Chithra and Shiva Nagendra, 2014) favoured high moisture content in the soil which in turn accelerated the rate of soil respiration (Rastogi et al, 2002) and resulted in large amount of CO 2 effluxes from the soil (Mohanty and Panda, 2011). The CO 2 molecules emitted due to the soil respiration were accumulated due to prevailing of stable atmospheric conditions during night times which thus resulted in higher CO 2 concentrations at the study site.…”
