Nitrous oxide is a by-product of soil microbes that use nitrogen compounds from fertiliser and animal excreta as an energy source for their metabolism. The pressure difference arises from such meteorological factors, as changes in soil temperature, barometric pressure, wind movements and also rainfall and irrigation. The reality is that it takes thousands of years to create an inch of fertile topsoil, but it can be destroyed in minutes. So the partial pressure of oxygen is higher in the atmosphere than in the soil porespace and the partial pressure of carbon dioxide is higher in soil pore space than in atmosphere even though the total pressure in the atmosphere and soil pore spaces may be the same. Bodenkunde in Stichworten. Other, less common minerals include calcium, magnesium, and sulfur. When the soils begins to cool, the soil air contracts and the atmospheric gases enter into the soil. The presence of oxygen in the soil promotes easy germination of seed this is because oxygen constitutes 23% of the atmospheric air. The air in soil is in constant exchange with the atmosphere. The two primary reasons plants need is air to photosynthesize (make food) and to breathe. Any one of these essential soil functions would be reason enough to preserve our soil: taken together they are a compelling argument for urgent action.
