Crop yields on soils in developing countries decrease exponentially with increasing aridity82. Use plants to grow soil carbon: It is estimated that between 30-60% of the atmospheric carbon dioxide (CO2) absorbed by plants is deposited into the soil as organic matter in the form of bud sheaths that protect the delicate root tips and as a range of other root excretions. Less immediate but possibly even more significant impacts are anticipated due to changes in mean temperatures, increasing weather variability and sea level rising. Further Indirect effects corresponds to changes in growth rates or water-use efficiencies, through sea-level rise, through climate-induced decrease or increase in vegetative cover or anthropogenic intervention. Finally, climate influences the weathering rates of soil minerals, as well as their presence and location within the soil profile. Increases in grass yields are also generally expected. The first mechanism concerns the indirect effects of rising atmospheric concentrations of carbon dioxide on soil microbes, through increased plant photosynthesis and transfer of photosynthate carbon to fine roots and mycorrhizal fungi68-70 and heterotrophic microbes71,72. If under dry conditions higher temperatures result in extreme vapor pressure deficits that trigger stomatal closure (reducing the water diffusion pathway in leaves)99, then nutrient acquisition driven by mass flow will decrease100. Climates that are cold and dry have an opposite effect on plant growth and decomposition. could help maintain SOM contents and avoid increased CO, Careful planning of land management (e.g., timing and application of fertiliser applications) could help minimize potential increases in trace gas fluxes from soils, Conservation measures to maintain peatland moisture could help avoid drying out of peatlands and associated CO, Coastal management options should consider measures to protect aquifers from saline intrusion due to sea level rise where appropriate, Conservation measures for low-lying vulnerable coastal habitats need to be planned carefully with consideration of possible impacts on trace gas fluxes. These direct influences are modified with the impact of vegetation characteristics (type, density, dynamics, species composition, biomass production, litter and root characteristics), human intervention like land use, cropping pattern, agrotechnics, amelioration (including water and wind erosion control, chemical reclamation, irrigation and drainage) and other activities radically modify ing the field water balance and its components. Organic matter levels are also generally lower in soils formed in forested situations than in those formed in grassland situations. One of the biggest influences on farm productivity and its resilience to climate variations is soil health. The fate and losses of pesticide could be complex nature depending upon the interactions between pesticides and the environment, incidence of pests and diseases under a changing climate (increased temperature causes rapid degradation, drier climate increases pesticide persistence, increased rainfall enhances by pass flow and downward movements). According to researchers, climate change will likely alter the soil system in various ways. Too much heat in your soil can prevent seeds from germinating properly and can … Such plant-mediated indirect effects of climate change on soil microbes operate through a variety of mechanisms, with differing routes of feedback to climate change but these can broadly be separated into two. This, combined with climatic variation and a predicted increase in extreme weather events, has created ideal conditions for soil erosion. Organic matter also helps cool the soil. Soil biological parameters Mountain glaciers and snow cover have declined on average in both hemispheres. In fact as they are adding between 30-60% of the organic compounds they create through photosynthesis into the soil they are increasing soil fertility. From the relationship between runoff and precipitation intensity and frequency it was found that rainfall intensity had a greater effect than rainfall frequency on runoff. There are many uncertainties in deducing the consequential climatic effects. Changes in Sea Surface Temperatures (SST), wind patterns and decreased snowpack and snow cover have also been linked to droughts. The rate was faster over 1993-2003, about 3.1 mm per year. Each of these processes can be accelerated or inhibited by changes in external conditions due to global change as63: Acidification, salinization, sodicity problem in soil: While temperature increases are forecast for most parts of the world, there is less certainty about precipitation changes. Water is also the principal medium for the erosive or percolative transport of solid particles. Greenhouse gases: Our planet is made habitable by the presence of certain gases which trap long-wave radiation emitted from the earths surface, giving a global mean temperature of 15°C as opposed to an estimated -18°C in the absence of an atmosphere12. These include carbon and nitrogen cycling, acidification, risk of erosion, salinisation, all of which will impact on soil health (Fig. Again changes due to climate change are expected to be relatively well buffered by the mineral composition, the organic matter content or the structural stability of many soils. General circulation models indicate a marked change in soil moisture regime for some areas and therefore changes also in soil erodability, vegetation and land use. The parameter η11 describes the rate of change of quality. It also affects soil water content, its conductivity and availability to plants. Climate change has both direct and indirect effects on the activities of soil microbes that feedback greenhouse gases to the atmosphere and contribute to global warming (Fig. Impact of climate change on chemical and biological properties in contaminated soils: The relationship between climate parameters and soil properties can also be subject to confounding effect that may exist between different climate parameters. In this The integral influence of climate-hydrology-vegetation-land use changes are reflected by the field water balance and soil moisture regime28,29,30. Total organic matter, total carbohydrate and humic material extracted by various reagents each gave highly or very highly significant correlations with aggregate stability. However, changes in ecosystems and migration of vegetation zones may seriously affect less migratory soil flora and fauna through increased temperature and rainfall changes. However, it is important to note that erosion is site specific and different permutation of conditions can increase or decrease it. Similar is the case of arsenic contamination in the soils of West Bengal where the warmer climate induces arsenic contamination build-up through the increased irrigation of arsenic contaminated groundwater108. Increasing atmospheric CO2 concentration can reduce the impact of salinity on plant growth80.
