In view of the growing awareness about eco-friendly organic farming, vermicompost (VC) could be a very good option for increasing crops yield. The organic carbon in VC releases nutrients slowly and steadily into the system and enables the plant to absorb these nutrients. To assess the effect of VC on soil fertility, growth and yield of stevia in acid and non-calcareous soils, an experiment was ...

Carbon-rich biochar derived from the pyrolysis of biomass can sequester atmospheric CO, mitigate climate change, and potentially increase crop productivity. However, research is needed to confirm the suitability and sustainability of biochar application to different soils. To an irrigated calcareous soil, we applied stockpiled dairy manure (42 Mg ha dry wt) and hardwood-derived biochar (22.4 Mg...

The term "diffuse neurofibrillary tangles with calcification" (DNTC) is proposed for a new form of presenile dementia. It is characterised by slowly progressive cortical dementia in the presenium, localised temporal or temporofrontal lobar atrophy, numerous neurofibrillary tangles widespread in the cerebral cortex, and pronounced calcareous deposits; 16 cases of DNTC, have been reported.

Iron deficiency is a serious problem around the world, especially in developing countries. The production of iron-biofortified rice will help ameliorate this problem. Previously, expression of the iron storage protein, ferritin, in rice using an endosperm-specific promoter resulted in a two-fold increase in iron concentration in the resultant transgenic seeds. However, further over expression o...

Nitrification inhibitors (NIs) have been used extensively to reduce nitrogen losses and increase crop nitrogen nutrition. However, information is still scant regarding the influence of NIs on nitrogen transformation, nitrous oxide (N2O) emission and nitrogen utilization in plastic-film-mulched calcareous soil under high frequency drip-fertigated condition. Therefore, a field trial was conducted...

Nitrogen usually gets the most attention when it comes to fertilization, and there are good reasons for that. It's the nutrient with the most visual effect and results in the greatest effects to the plant. However potassium (K) is also essential, as is phosphorous (P). We all know how to apply nitrogen using the range of fertilizer sources available today to superintendents and field managers. ...

The undamaged test of a range of aplousobranch ascidian species is shown to be chemically neutral. Acid is generated by surface test cells following cell lysis and is rapidly neutralised in the presence of calcareous test inclusions and/or sea water. Neither the capacity to produce acid nor the presence of vanadium prevents predation on ascidian species in the field.

in present study, diversity and relative abundance of calcareous nannofossils of the boundary between abtalkh and neyzar formations in dobaradar, kalat and chahchaheh sections were studied. taxonomical studies of calcareous nannofossils in the studied areas led to identification of 24 species in dobaradar, 27 species in kalat and 32 species in chahchaheh sections. based on identified nannofossi...
