It lays the foremost emphasis on C-stabilization in agricultural soils representing the largest terrestrial organic C pool 3 times of CO2 in the atmosphere and 240 times the fossil fuel emissions yearly (Ciais et al., 2014). Therefore, soil organic carbon (SOC) sequestration fixing of long-lived C pools in soils for longterm, is an imperative mitigation strategy for climate change (Nawaz et al., 2017), since adding a few percent more to the net C storage in soil embodies a substantive C sink potential (Paustian et al., 2016; Ghosh et al., 2018). As well, SOC in the form of organic matter is crucial in sustaining the essential soil functions, for instance, plant nutrient dynamics and so the soil productivity (Liu et al., 2017). Further...

Twenty eight percent of the total lands are under cultivation providing employment to 45 % of the total labor force in the country. It feeds to a population of 155 million and its raw commodities and finished products have a major share in foreign exchange earning. Still, the introduction of improved technologies in agriculture is not keeping pace with the demands of production. Although, there is enough number of scientists in the research organizations and universities alongwith a huge staff in the department of agriculture extension, but the outcome is not so as expected. The main weakness identified in the transfer of technology is the lack of communication resources between the technology generators (agriculture scientists) and the end-users (farmers). Until recently, the scientists themselves were not having access to the knowledge of latest technological d...

They are considered as powerful tools in nanotechnology and are being exploited for their potential use in modern industries. They have versatile application in a variety of industries from automobile to agro-chemicals. On the other hand they have shown to exert physical and physiological changes in the plants. Here we reviewed plant uptake, accumulation, phytotoxicity of nanoparticles and modern fertilizer and insecticide formulations with blends of nanoparticles. In this context we have critically analyzed dynamics of plant growth and their interaction with different nanoparticles.

With this objective, biomass availability for bioenergy production could be ensured alternately by exploring non-conventional plant species and algae. This idea was examined by growing divergent plants and algae species separately in horizontal subsurface flow constructed wetlands and raceway ponds, later collected their biomass for bioethanol determination. Through this approach, sewage was fed to constructed wetlands and raceway ponds as influent and passed through these cultivated systems for wastewater treatment. Although all the four plant and algae species showed efficient results in sewage treatment, however, Ipomoea aquatica and Spirogyra were statistically superior to the others and produced the highest biomass yield of 4.5 and 4.1 kg m −2 , respectively. For bioethanol production, alkali–autohydrolysis combined pretreatment followed by enzymatic hydrolysis with two successive incubation periods (12 and 24 h) were employed. Results suggested that Spirogyra biomass rendered greater carbohydrate and ethanol concentration (3.7 and 1.9 mg L −1 , respectively) during 24 hours of incubation, whereas Oryza sativa acquired similar carbohydrate concentration as Spirogyra but slightly lower bioethanol yield. This study postulates, Spirogyra is promising for wastewater treatment coupled with bioethanol production.

In this work, we report a novel aerobic bacterial strain isolated from sludge of an oil refinery. Microscopic and staining analysis revealed that it was a gram positive rod with the capability to thrive in a medium (9K) supplemented, with Fe(2+) ions at an acidic pH (~3.2). The magnetic behaviour of these cells was tested by their alignment towards a permanent magnet, and later on confirmed by magnetometry analysis. The X-ray diffraction studies proved the cellular biosynthesis of magnetite nanoparticles inside the bacteria. This novel, bio-nano-magnet, could pave the way for green synthesis of magnetic nanoparticles to be used in industrial and medical applications such as MRI, magnetic hyperthermia and ferrofluids.
