Testing the Importance of Nitrogen in Plants and the Effects of Organic Matter

The use of too much fertilizers, and in particular, of fertilizers with high concentrations of nitrogen, has been linked to reduced biodiversity (Xiankai et al. 2010). It becomes necessary to consider the detrimental effects of high concentrations of fertilizer in the reduced spaces. Fertilizers are salts, and therefore high concentrations of fertilizers can deplete the plant from water.

It is also affordability, convenience, and effectiveness in nourishing plants; however it can also have disadvantages when using chemical based fertilizers. Plants will show signs of lacking nutrient the inorganic fertilizer was separate help over organic choices, it depends on soil organisms to first, break down the organic substance before the nutrients can be out. Inorganic fertilizer’s fast delivery elements and minerals eliminate this potential problem. Inorganic fertilizer, which is often reasonably priced, consists of mineral-based nutrients manufactured for instant application on crops. Unlike the organic variety, inorganic fertilizer does not need to decompose over time to supply nutrients to plants. Inorganic fertilizer contained balanced amounts of nitrogen, potassium and phosphorus to supply plants and to grow it faster. These are the substance of chemical gain from the processes in cultivating the first one is urea. Nitrogen as urea can be lost to the atmosphere if fertilizer urea remains on the soil surface for total periods of time throughout warm

Poor soil management can lead to biological, chemical, and physical degradation, which can in turn negatively alter the activity of

The pH of soil is important for the absorption of nutrients into the plant. Of the 17 needed plant nutrients 14 of them are acquired through the soil. Acidity is needed to break down and dissolve these nutrients. The nutrients are able to dissolve into the soil faster when the acid is acting as a solute. Another way the pH affects the soil is by influencing microorganisms. The bacteria is crucial in the growth and development of the plant, the bacteria’s role is to break down and decompose organic matter in the soil. If the pH of the soil is too high the acid will slow down and eventually stop the microorganisms. Most plants ideal pH is between 6-7, slightly acidic. Many plants are outliers and thrive in pH such as carrots and corn, which can withstand pH as low as 5.5. If the pH of the soil is too high for the desired crop farmers can add material such as limestone, and wood ashes to raise the pH to the desired level. The pH of the soil can also be changed naturally through the leaching of calcium, magnesium and sodium by rainwater. Carbon dioxide from rotting organic matter can also increase the pH of the soil. Acids can also be created organically in the form of sulfuric and nitric

The purpose of this lab was to investigate and observe the effects of organic vs. synthetic fertilizers on plant growth by planting lima beans with added amounts of fertilizers, and to see how does adding different nutrients to the soil affect the growth of the lima bean? A significant difference was examined between the plants that contained manure and miracle growth, unfortunately the plant with no additional fertilizers (Plant #3) did not show any growth. The plant that grew the most was the one that contained manure, to an extent the one that grew the most in a short period of time was the one that contained miracle growth, as shown in figure I. The hypothesis explaining if the Lima Bean plant contains synthetic nutrients in the soil then

*Nitrogen is circulated in a biogeochemical cycle and is a necessary element in the structure of living things.

The nitrogen cycle is extremely important. This is because of the importance of nitrogen itself. Nitrogen is a basic element of life. It also makes up 78 percent of the Earth's atmosphere. It forms an essential part of amino acids (which make up proteins) and DNA. Nitrogen is essential for all living cells.

According to ….the earth’s atmosphere contains 78% nitrogen, 21% oxygen, and 1% CO2 and other gases. Nitrogen makes up almost four fifths of the air we breathe. we already have 25% more nitrogen percentage than is said in this article . we just inhale and exhale the nitrogen back out again, unchanged. It is essential for the growth of most living things. She may think that nitrogen is harmful but as identified on …. It is a fundamental for life .

People live in different areas of the country. These areas may have different types of soil. The types of soil may be rich top soil, sandy soil, and rocky soil. Many people want to grow their own vegetables and the type of soil could affect the way vegetables will grow. This research is scientifically important because it will show how vegetables grow in different types of soil. This would have an impact on society because it would help those who wanted to grow a vegetable garden on how to best prepare the garden soil for radishes.

The types and growth influences how much nitrogen is captured and released when nitrogen shows higher availability to follow crop. Ii) It improves soil structure when cover crops help open up soil and access to water and nutrient can be improved. Iii) Cover crops supply ground cover for the risk of soil erosion by water or wind, in this case there is possibility of reduction in erosion risk. Iv). Habitat creation which enables cover crops to provide a winter cover and habitat for wild birds, insects and small mammals, and this provides grazing opportunities for wildlife. v) Nutrient losses are reduced – cover crops reduce soil run-off lessen the loss of phosphate fixed to soil particles. This also reduces nitrate leaching and losses of nitrate and nitrate and nitrous oxide. Vi). Weed and pest management – most of cover crops type normally contend with range of weed and assist to provide a clean seedbed for crops. Lastly, water quality are improved and benefited cash crops, this reduces losses of nutrient, sediment and pesticides. It impacts on water quality and habitats when the soil run-off is in high level nutrient and cause choking to other aquatic life.

Microorganisms support the soil and the plants ability to grow but are only utilized with responsible nutrient management. If microorganisms are destroyed, crops will produce less yields and the soil will not be as beneficial. Since microorganisms are so complex, to find out how to restore them to normal would be a problematic task. Once microorganism in the soil are better understood, farmers will have a better ability to manage the nutrients in the soil so nutrients can be added that support the microorganisms.

Nitrogen is essential for all forms of life in that it is required to biosynthesize basic building blocks of plants, animals and other life forms. Atmospheric nitrogen is relatively inert; however, the fixation process can free up the nitrogen atoms from their diatomic form (N2) to compound form (NH3) so they could be used in many ways. Biological nitrogen fixation provides about 65% of the biosphere’s available nitrogen, and most of this is done by the cooperation between legume and rhizobia. In fact, symbiotic nitrogen fixation by rhizobia in legume root nodules injects approximately 40 million tonnes of nitrogen into agricultural systems each year.

Research has shown that nitrogen deficiencies this severe in oranges will result in considerable yield losses.

Mungbean (Vigna radiata (L.) Wilczek), also known as green gram, is a major pulse crop of India. Mungbean has been vastly grown on the Indian subcontinent as well as parts of Asia. Mungbean has also been referred to be part of the poor man’s meat because of its high nutritive value as well as its ease of digestibility. India alone accounts for 65% of its world acreage and 54% of the production (Biyani et al., 2012).The pulse is of short duration and is a multifunctional pulse as it is now known to provide a good quality combination of fodder for livestock, green manure and food. Mungbean is known to fix atmospheric nitrogen and its symbiotic association of nodulated roots and Rhizobia has enabled farmers to save money on procuring N-fertilisers. If grown in a cropping system mungbean’s rhizodeposition abilities might contribute significantly to higher C and N availability in soils to succeeding crops (Zang et al., 2015). Mungbean has low input requirements and has the ability to provide much required nutrients and moisture for a succeeding crop (Singh et al., 2011). India and the Indian subcontinent as well as the rest of the world face a problem of increasing population which is compounded by dwindling natural resources such as land (soil

Constant deterioration of soil health during past three decades is one of the most serious second generation problems of Green Revolution in India, causing not only stagnation in food production but also threatening the nutritional and economic security. The problem is more acute in high productivity areas of Indo-Gangetic Plain Region i.e., Trans-Gangetic Plains (TGP, representing Punjab and Haryana) and Upper Gangetic Plains (UGP, representing Delhi and Western U.P.), where intensive cereal-cereal cropping systems are predominantly followed with indiscriminate use of nutrients and irrigation water, and also with excessive tillage using heavy machinery (Yadav et al. 1998). Major soil health problems emerged due to continuous adoption of this kind of farming are depletion of soil organic matter (SOM) both in terms of quality and quantity, emergence of multi-nutrient deficiencies and deterioration of soil physical properties - especially sub-surface compaction and poor aggregation (Hobbs and Morris 1996). The sustenance of high yields in these otherwise productive areas is becoming increasingly difficult owing to soil-related constraints. Hence, the farmers have started using greater than recommended rates of N fertilizers, particularly in the most prevalent rice-wheat cropping system, in order to maintain the yield levels that were attained previously with relatively less fertilizer. Such emerging trends of indiscriminate N fertilization need to be curbed, for
