The Effect Of Nitrogen Fertilizers On Some Meteorological Elements



PDF, ebook, epub (ePub, fb2, mobi)

Greenhouse gases (CO2 and N2O) play an important role in the atmospheric chemistry and in the global warming. According to the emissions inventories that governments submit to the UNFCCC, agriculture accounts for about 15 % of global GHGs. Agriculture contributes about half of the global emissions of two of the most potent non-carbon dioxide greenhouse gases nitrous oxide and methane. Nitrous oxide emissions from soils, fertilizers application and manures).Agricultural soils are considered sources of carbon dioxide emissions and nitrous oxide. The nitrogen fertilizer is the most important sources of nitrous oxide emissions.Clay soil fertilized with urea gave the largest amount of emissions of carbon dioxide and were15607 ppm, while in the control chambers were 9228 ppm (The proportion of clay soils contribute in the total emission amounted to 59.1% and was the carbon dioxide emitted by the urea ratio of 40.9%). Sandy soil fertilized with urea gave the highest emissions of nitrous oxide, where 6.07 ppm.In the first experiment we observe that the largest difference in temperature was 1.5 oC.In the second experiment also note that the largest difference in temperature was 1.73 oC .

Samples must be representative of the area collected according to lab instructions and above all free from soil and other contaminants. use of synthetic nitrogen N fertilizers and in emissions of N as forms of air pollution. Chemical fertilizers are high in nutrient content such as nitrogen. Nitrogen frequently increases root growth and foraging capacity for phosphorus. The average pest number at peak time 13 Standard Meteorological Week . Everyday low .


Saber Effect

In fact nitrogen is a structural element of chlorophyll and protein molecules and thereby affects . If the main ingredient in the fertilizer is nitrogen then the fertilizer will be described as a nitrogen fertilizer. Much of this debate is because synthetic N fertilizer can positively or negatively affect SOM mineralization. Djaman et al. The Effect of Emitted Gases From The Nitrogen Fertilizers On Some Meteorological ElementsGreenhouse gases CO2 and N2. While fertilizer overuse causes this change nitrogenpolluted air caused by nitrates from automobiles and industrial plants also results in this acidification of the soil when acid rain falls.. Silspur 2 1Faculty of Agricultural Engineering Islamic Azad University VaraminPishva Branch Iran 2Agricultural Research Institute of Varamin Iran. Some meteorological parameters of experimental area at Bornova in 2013 and 2014. Nitrogen constitutes 78 percent of Earths atmosphere and is a constituent of all living tissues. respectively although there is some uncertainty in the resultant effect on yield and soil fertility. manure increases the essential elements such as nitrogen N phosphorus P potassium K calcium and magnesium content in soil Havlin et al.
