In the post-Viking era, Mars was defined largely in terms of geomorphology and the planet-wide cycles of water, dust, and CO2. In the 21 century, we have increasingly come to understand Mars in terms of chemical processes. Soil chemistry has become a key to understanding geological, astrobiological, and even atmospheric processes. What the future holds for our understanding of Mars will be dete...

This review covers aspects of soil science and soil biology of Antarctica with special focus on King George Island, South Shetlands, the martitime Antarctic. New approaches in soil descriptions and soil taxonomy show a great variety of soil types, related to different parent material, mainly volcanic origin, as well as on influences by soil biological processes. The spread of higher rooting pla...

than other regions of the world (Mitchell et al., 1990; Maxwell, 1992). Summer air temperatures in northern To investigate the interactions among mineral N, C availability, Alaska are predicted to increase 3 to 68C over current microbial biomass, and respiration in arctic soils, we sampled soils five times during a growing season from a toposequence on a slope levels, whereas precipitation duri...

Plant protection represents one of the strategies to fill the yield gap and to achieve food security, a key topic for India development. Analysis of climate risks for crops indicates that South Asia is one of the regions most exposed to the adverse impact on many plants that are relevant to inhabitants exposed to food safety risks. Furthermore, accumulation of pesticide residues in the aquatic ...

Human activity is one of the main causes of the physical, chemical and biological degradation of soils. This degradation implies a change in soil quality as it involves both a decrease in productivity and changes in the ecological functions of the soil. The objective of the present study was to investigate the effect of soil use on soil biochemical properties, with the aim of providing data tha...
