What’s known to us all is that nature is an organic whole. What’s more,there are four major material cycles:the hydrologic cycle, the nitrogen cycle, the phosphorous cycle and the carbon cycle. In this essay, I will concentrate more on the carbon cycle and the nitrogen cycle. Let us take carbon dioxide and methane as example. Besides, with the development of the society,on the one hand,people’s living hoods becoming more and more comfortable and the transport is more and more convenient. However, as the old saying goes “ Each coin has two sides”, on the other hand, the quantity of gases which can lead to global warming is getting larger and larger, having giant impact on the environment, First of all, let us have a basic understanding of greenhouse gases. Greenhouse gases are gases that can lead to greenhouse, including carbon dioxide, methane and water vapor. Human activities’ increasing, the burning of fossil fuels, the increase of environmental pollution and the change of land use and cover result in a sustained increase in the concentration of greenhouse gases. In the last few decades, carbon dioxide, methane, and nitrogen oxides in the atmosphere have increased by 0.5%, 0.8%, and 0.3% annually,. The development of modern agricultural science and technology makes the agriculture in the regulation plays a more and more important role on controlling the climate change. In addition to the photosynthesis and the decomposition of microorganisms, the use of organic fertilizers also has a certain effect on the circulation of greenhouse gases.It is well known that some of the greenhouse gases come from the breath and decay of life in nature, and the other source of greenhouse gases.come from soil.The focus of this article is to discuss the effects of different uses of soils and different soil management on the emissions of carbon dioxide and methane.
It is widely believed that the soil will emit a certain amount of carbon dioxide and methane into the atmosphere every day. Carbon dioxide is mainly derived from the respiration of plants and methane is produced during the decomposition of microorganisms. At the same time, due to the photosynthesis of plants, it can absorb some of the carbon dioxide and methane in the atmosphere.According to the survey data, among the quantity of the emissions of greenhouse gases from the agricultural production process, nitrogen oxides take up the most, methane is the second and carbon dioxide is least. The amount of carbon dioxide in the atmosphere has been reduced by effective usage of soil and different managements to the soil. The carbon in the soil comes from the residue of plants and the particles of organic carbon. Carbon as an important component of soil humus has a great effect on the full play of the function of the soil. Soil carbon can promote the cycle and absorption of nitrogen and phosphorus in soil.In this way, carbon dioxide and methane can be carried out in the soil as a carrier.The nitrogen cycle mainly by organic matter in the soil will produce fruit and plants by microbial decomposition of withered rotten soil animals and plants of the ammonium ion in the formation of mineralization, nitrification after formation of nitrate ions, finally through denitrification to the atmospheric emissions of N2, NO, N2O.
Based on the analysis of the existing data, I found that the land use has experienced a transformation from the subtropical rain forest to the lychee plantation. During this period, excessive grazing lead to the destruction of the rain forest vegetation, and after an effective way of land use adjustment, beans are chosen to grow in the soil.Among the four major material cycle, people focus more on the nitrogen cycle,the reasons are as follow.First of all,if the deposition of nitrogen continued to increase (up to 100kg-N ha-1 y-1), the soil had been acid, the root of plant had been damaged and microbe communities had been changed. In addition, long time of nitrogen oxides in the water body will lead to eutrophication of water quality, which will cause a large area of aquatic plants died. Therefore, the result of eutrophication of water bodies is that the decomposition of the microorganism can be enhanced, so that the greenhouse gas emitted by water bodies will increase rapidly and the GWP will be elevated.Besides, the more the nitrogen is, the more atmospheric N2O will be. Last but not least, more nitrogen in the atmosphere means less carbon dioxide, while plant growth depends on carbon dioxide uptake. As for CO2 and CH4, it is widely thought they are chief culprits of global warming. Frankly speaking, because carbon dioxide and methane are flammable and poisonous gases, most people only pay attention to their characteristics, they will let the global warming, but the two have a great role in agricultural production.
Studies show that there are many factors that affect the soil respiration. Soil physical and chemical properties such as temperature, water content, PH, soil texture and other factors can directly affect the amount of microbial biomass and its physiological process, thereby affecting the emission of greenhouse gases. The soil temperature, moisture and organic matter content are the most important factors that affect the soil gas emission.Soil At the same time, greenhouse gas emissions have obvious seasonal variation. In terms of CO2 emissions, it is generally considered that the summer emissions are higher, the winter is lower. The seasonal variation of the absorption rate of CH4 in soil was the opposite, which basically showed the lowest change in winter.Soil is an important component of terrestrial ecosystem, and it is the main storage and exchange of carbon in the system composed of atmospheric and terrestrial bio-tic community. It is estimated that there are about t 1.4x1012-1.5x1012 carbon in the world in the form of organic matter in the soil. The carbon dioxide emitted by soil is 10 times than that from burning fossil fuel combustion emissions.Soil grown plants can produce a far-reaching impact on these factors, so how to make plant species and soil properties get the perfect combination, ensure the plant yield based on reducing greenhouse gas emissions, and come true the dream that one plus one is greater than two is the most urgent problem which we need to take into consideration. Let’s have a look on these two formulas first.RF→Pasture=6.7 increase in GWP RF→Pasture→Lychee=19 increase in GWP. WFPS RF=49%→pasture=63%→lychee=80%. What conclusion we can draw is that different land use will have different effect on greenhouse gas emission. What we know is that the subtropical rain forest can absorb a certain amount of methane and carbon dioxide with its rich vegetation. However, due to the large number of microbial species, the rain forest emissions of more than other types of nitrogen oxides.Pasture is usually emitted carbon dioxide and nitrogen oxides, while absorbing some of the methane
In order to verify our view about greenhouse gas emissions for different types of land speculation, we chose nine rooms to simulate the litchi plantation, soil pasture and subtropical rainforest, and the data were continuously monitored. Through the study of the data obtained, we found that in these three, the rain forest can absorb the amount of methane on the ranch, while the litchi plantation will be a daily emissions of methane to the atmosphere.Due to different processes of plant growth and development, what is more, the soil acidity and alkalinity of the soil containing organic matter, the amount of greenhouse gases emitted by each type of land is different. All monitoring data are designed to make the results more intuitive and can help people to select the plant species in different soil.
In short, the process of greenhouse gas emissions of carbon dioxide, methane and nitrous oxide, is an important process of carbon and nitrogen cycle in terrestrial ecosystem, and is the main output pathway of soil carbon and nitrogen pool. Different soil types of greenhouse gas emissions and absorption capacity is different, we need to select the appropriate plant according to the situation of the soil itself to plant, so as to reduce greenhouse gas emissions to a minimum. Soil itself has an important role in climate change, can regulate the temperature and humidity of the atmosphere, but also to reduce the impact of the greenhouse effect by improving the gas cycle. The soil itself is an encyclopedia, and as the old saying goes “Rome is not build in a day”, the process of learning knowledge is a continuous process that requires patience.. After all, knowledge has no limit.And it is high time that we took more management to study the soil’s function on the greenhouse gas emission and control. Only by doing more careful research with our patience can we master the secrets of the soil.
