Of late, intensive farming for higher food production is often associated with many negative implications for soil systems, such as decline of soil organic matter (SOM), increase in risks of soil erosion by wind and/or water, decline in soil biological diversity, increase in degradation of soil phys...

Preparations of PVA/PEG/zirconium oxide films for biomedical application as antibacterial are investigated for electronics applications. Structural and optical characterizations of PVA/PEG/ZrO 2 nanocomposites are examined. The results indicate that the absorbance and optical parameters of polymer b...

Examples of how to simulate performance of conservation agriculture (CA) and conventional tillage (CT) practices using cropping systems models are rare in the literature, and from the Eastern Gangetic Plains (EGP). Here we report a comprehensive evaluation of the capacity of APSIM for simulating the...

Effects on soil nitrogen accretion and potentially mineralisable nitrogen were studied as part of a long-term field experiment established in 1986 to test alternative legume-based systems for restoring fertility in a Vertisol. Organic C accretion was also measured to ascertain the changes in organic...

Key soil parameters, organic matter, soil pH and plant nutrients determine the capacity of a soil to sustain plant and animal productivity. Conservation agriculture (CA) and crop diversification or intensification may change these soil parameters positively or negatively, which eventually affect lon...

The effectiveness of the inactivated BBIBP-CorV vaccine against severe COVID-19 outcomes (hospitalization, critical care admission and death due to COVID-19) and its long-term effectiveness have not been well characterized among the general population. We conducted a retrospective cohort study using...

Mineral nitrogen release following legume-based cropping systems for restoring the fertility of a Vertisol and the yield response and N uptake of subsequent wheat crops was studied. Legume phases of pastures, including a 4 year grass+legume ley, and lucerne and medic leys (~1 year) were terminated i...

Nitrogen fixation was measured using two isotopic techniques over 2 years as part of a long-term field experiment established to test alternative management strategies for restoring fertility in a vertisol at Warra, Southern Queensland. Treatments containing legumes were: grass- legume ley (purple p...

Cultivation and cropping of soils results in a decline in soil organic carbon and soil nitrogen, and can lead to reduced crop yields. The CENTURY model was used to simulate the effects of continuous cultivation and cereal cropping on total soil organic matter (C and N), carbon pools, nitrogen minera...

Rice is predominantly grown on puddled soils (puddling is achieved through wet tillage in ponded water to create a soft soil environment and impermeable sub-soil layer) in the Eastern Gangetic Plains (EGP) of Bangladesh. Puddling is often discouraged while practicing conservation agriculture (CA) to...

Increasing productivity of the rice-wheat system (RW) in the Eastern Gangetic Plains (EGP) is a major challenge in the context of the various economic (increasing cost of labour, irrigation water, and energy) and bio-physical (water scarcity, depletion of soil fertility, and climatic variability) co...

Methane is a potent greenhouse gas with a global warming potential ~28 times that of carbon dioxide. Consequently, sources and sinks that influence the concentration of methane in the atmosphere are of great interest. In Australia, agriculture is the primary source of anthropogenic methane emissions...

Sperata seenghala is one of the largest freshwater catfish of Indian sub-continent. This fish has good market demand as food fish due to its good taste with high nutritional value and for this reason it constitutes an important capture fishery of all the major rivers and reservoirs of India, Banglad...

High nitrous oxide (N2O) emissions (2–10% of fertiliser N) were observed previously from acid soils cropped with sugarcane (Saccharum officinarum) in Australia. We assessed the impact of lime, a nitrification inhibitor (NI, as 3,4-dimethylpyrazole phosphate, DMPP), and copper (Cu) on N2O emissions f...
