Nitrogen

as it acts as a reservoir or sink for the accumulation of nutrients. Even water itself is recycled through precipitation, evaporation and condensation. This is a typical cycle that can be observed for the vital elements of life such as carbon and nitrogen. Microbes are essential to the cycling of nutrients in virtually all environments, including extreme ones such as hydrothermal vents and acid lakes. Specifically in the marine environment, they are a building block to carbon flow, organic…

tropical regions. 2. What is unique about this fern? Why is it called ‘Azolla Superorganism’? This fern is unique because it is a little fern and has massive potential, and its called superorganism because it is symbiotic that captures all the nitrogen fertilizer it needs to grow from the air around it. In Asia, they grow it along with…

Every minute, a child dies from a water-related disease; combine that with adult fatalities from the same diseases, and the number skyrockets to more than 840,000 annual deaths (“Water Facts”). These individuals are only a tiny fraction of the 750 million people worldwide without access to clean drinking water, water that is often used to sustain what little agriculture they may be cultivating. This crisis closely interrelates with the worldwide hunger issue, which is so prevalent that 21,000…

highly enriched by nutrients associated with natural erosion of fertile soils, such as lakes located in areas of rich agricultural soils. The nation’s waterways contain excessive amounts of nitrogen from fertilizer. As a result of all this excessive nitrate, algae and other microorganisms take up the nitrogen, bloom and, after they die, suck the oxygen out of coastal waters. These nitrates and oxygen molecules that plants need to grow eventually find their way into rivers, lakes, and oceans and…

1. Even though, the eruption of Mount St. Helens volcano was one of the most severe eruptions yet, some plants survived the upheaval. Ecologists were surprised to find the emergence of plants in the mass of ash covered terrain. As the ecologist Dale quoted, “It gave the impression of total lifelessness.” However, roots being guarded in moist soil, resilient plants, and snow sheltering trees were the three main reasons vegetation survived. 2. The plants, and trees that endured the eruption are…

possibility is that in monoculture for higher urease activity, N-fertilizer rate was same in monoculture and intercrops, and intercrops utilized soil urea faster than monoculture. Nitrite reductase, protease and nitrogenase play significant roles in nitrogen cycle and higher activities of these enzymes showed that vital microbial community enhanced in intercropping system. The nitrogenase enzyme catalyzes the reduction of atmospheric dinitrogen to ammonia. This process is energy expensive and…

instrument was done using 195 an alfalfa standard with a known nitrogen content of 3.38 ± 0.04%. A series of blank determinations 196 were performed in order to get rid of any element in the instrument. Calibration of the instrument 197 was done using an alfalfa standard with a known…

need certain macronutrients and micronutrients. They need the macronutrients: nitrogen, phosphorous, potassium, calcium, sulfur, magnesium; and the micronutrients: boron, chlorine, manganese, iron, zinc, copper, molybdenum, and nickel. (3). Fertilizer enhances the growth rate of plants. Fertilizer adds nutrients and modifies the water retention and aeration of plants. Fertilizer contains three main macronutrients: nitrogen for leaf growth; phosphorus for the development of roots, flowers, seeds,…

of corn with different Nitrogen concentrations to see which concentration has the greatest effect on the corn plant.…

revealed existence of a nitrogen isotope sensitive band from a peak/trough at 1334/1309 cm-1 demonstrating that there is nitration of the vinyl group to some extent at pH 7.5 without nitrite coordination to the heme. This result was consistent in both the high and low frequency resonance spectra. At pH 5.5, the difference in traces of the high frequency RR spectra demonstrated formation of a 6cLS heme species and presence of two peak/trough features suggesting the nitrogen and oxygen isotope…
