Predicting the amount of sequestrated carbon in rangeland soil under the effect of soil sampling depth and height using the response surface methodology (RSM)
Background and objectives: Organic carbon is one of the important parameters to determine soil fertility, and production ability and is a mind index for showing soil quality, especially in dry and semi-dry lands. The rangelands are composed of about 50 % of the world's lands and have more than 33 % of carbon reservoirs on earth. Considering the ranges as the most important terrestrial ecosystem...

متن کاملIron, phytoplankton growth, and the carbon cycle.
Iron is an essential nutrient for all living organisms. Iron is required for the synthesis of chlorophyll and of several photosynthetic electron transport proteins and for the reduction of CO2, SO4(2-), and NO3(-) during the photosynthetic production of organic compounds. Iron concentrations in vast areas of the ocean are very low (<1 nM) due to the low solubility of iron in oxic seawater. Low ...
متن کاملOpen Ocean Iron Fertilization for Scientific Study and Carbon Sequestration
The trace element iron has been recently shown to play a critical role in nutrient utilization, phytoplankton growth and therefore the uptake of carbon dioxide from the surface waters of the global ocean. Carbon fixation in the surface waters, via phytoplankton growth, shifts the ocean/atmosphere exchange equilibrium for carbon dioxide. As a result, levels of atmospheric carbon dioxide (a green...
متن کاملEstimation of Soil Carbon Sequestration Rate in Steppes (Case Study: Saveh Rudshur Steppes)
Since Renaissance, the natural ecosystems have fallen into a complete state ofdisarray due to the rise in the amount of carbon dioxide. Soil, the unsparing stuff, is one of themajor sources of carbon storage, and plays a paramount role in the global equilibrium ofcarbon as well as carbon sequestration. Given that Iran is benefiting from vast steppes, therate of carbon sequestration in them dese...
