Soil Chemical Analysis

Shallow groundwater affects terrestrial ecosystems by sustaining river base-flow and root-zone soil water in the absence of rain, but little is known about the global patterns of water table depth and where it provides vital support for land ecosystems We present global observations of water table depth compiled from government archives and literature, and fill in data gaps and infer patterns and processes using a groundwater model forced by modern climate, terrain, and sea level Patterns in water table depth explain patterns in wetlands at the global scale and vegetation gradients at regional and local scales Overall, shallow groundwater influences 22 to 32% of global land area, including ~15% as groundwater-fed surface water features and 7 to 17% with the water table or its capillary fringe within plant rooting depths

Global patterns of groundwater table depth.

Although cadavers constitute the gold standard for teaching anatomy to medical and health science students, there are substantial financial, ethical, and supervisory constraints on their use. In addition, although anatomy remains one of the fundamental areas of medical education, universities have decreased the hours allocated to teaching gross anatomy in favor of applied clinical work. The release of virtual (VR) and augmented reality (AR) devices allows learning to occur through hands-on immersive experiences. The aim of this research was to assess whether learning structural anatomy utilizing VR or AR is as effective as tablet-based (TB) applications, and whether these modes allowed enhanced student learning, engagement and performance. Participants (n = 59) were randomly allocated to one of the three learning modes: VR, AR, or TB and completed a lesson on skull anatomy, after which they completed an anatomical knowledge assessment. Student perceptions of each learning mode and any adverse effects experienced were recorded. No significant differences were found between mean assessment scores in VR, AR, or TB. During the lessons however, VR participants were more likely to exhibit adverse effects such as headaches (25% in VR P < 0.05), dizziness (40% in VR, P < 0.001), or blurred vision (35% in VR, P < 0.01). Both VR and AR are as valuable for teaching anatomy as tablet devices, but also promote intrinsic benefits such as increased learner immersion and engagement. These outcomes show great promise for the effective use of virtual and augmented reality as means to supplement lesson content in anatomical education.

The effect of different planting dates on survival, growth, yield and oil characteristics ofgeranium (Pelargonium graveolens L. Her.) was studied at Lucknow (Uttar Pradesh).  Freshterminal stem cuttings were planted on different dates starting from 31 October 2002 to March2003 at 15 days interval.  Cuttings planted in mid December recorded significantly highersurvival (93.5%), fresh biomass (539.7 q ha-1) and essential oil yield (54.9 kg ha-1) than earlieror later planted cuttings.

Soil available nutrients are very sensitive to change in response to management practices, and are considered to be chemical indicators of soil quality. The present investigation was conducted using two tillage managements for rice (puddled and non-puddled) and wheat (conventional tillage and no-tillage), three water managements and nine nutrient managements. After eight cropping cycles, puddling significantly increased soil organic carbon (SOC) (9.6 g kg(-1)) and available N (159.5 mg kg(-1)) compared to non-puddled soil. The continuous submergence increased the SOC, available Fe, Cu, Mn contents in soil following rice growth, whereas significantly decreased the available N, P and Zn ones. On the contrary, less frequent irrigation improved the SOC, available N and micronutrient contents after wheat cultivation. No-tillage significantly enhanced SOC, available N and Mn. Application of sewage sludge enhanced the soil available Zn (2.98 and 2.09 mg kg(-1)) and Cu (2.95 and 2.06 mg kg(-1)) following harvest of both crops. Organic sources like crop residues, green manure, sewage sludge and combination of organic sources were more effective in improving soil quality indicators.
