how does nitrogen affect plant growth

Nitrogen is a very important and needed for plant growth. It is found in Soil texture affects how well nutrients and water are retained in the soil.


Nitrogen is an essential nutrient for plant growth, development and reproduction. Despite nitrogen being one of the most abundant elements on earth, nitrogen deficiency is probably the most common nutritional problem affecting plants worldwide nitrogen from the atmosphere and earth's crust is not directly available to plants. Healthy plants often contain 3 to 4 percent nitrogen in their above-ground tissues. This is a much higher concentration compared to other nutrients. Nitrogen is so vital because it is a major component of chlorophyll, the compound by which plants use sunlight energy to produce sugars from water and carbon dioxide i. It is also a major component of amino acids, the building blocks of proteins. Without proteins, plants wither and die.

Robin L. Walker, Ian G. This paper investigates the effects of uptake of nitrate and the availability of internal N reserves on growth rate in times of restricted supply, and examines the extent to which the response is mediated by the different pools of N nitrate N, organic N and total N in the plant. Hydroponic experiments were carried out with young lettuce plants Lactuca sativa L. These differences resulted from the ability of the plant to use external sources of N more readily than their internal N reserves.

Nitrogen is an essential element of all proteins; it affects the growth of a plant and the quantity and quality of produce. The most obvious manifestation of an adequate supply is a luxuriance of leaf color and growth. Nitrogen is subject to losses in a greater variey of ways than any other nutrient: volatilization of ammonia, leaching and denitrification of nitrates. Nitrogen fixation by soil organisms is the only significant way to maintain the soil supply in a sustainable system. Table

Nitrogen is an essential element for plant growth and development; however, due to environmental pollution, high nitrate concentrations accumulate in the edible parts of these leafy vegetables, particularly if excessive nitrogen fertilizer has been applied. Consuming these crops can harm human health; thus, developing a suitable strategy for the agricultural application of nitrogen fertilizer is important. Organic, inorganic, and liquid fertilizers were utilized in this study to investigate their effect on nitrate concentrations and lettuce growth. The results of this pot experiment show that the total nitrogen concentration in soil and the nitrate concentration in lettuce increased as the amount of nitrogen fertilizer increased. Nitrogen is an essential element required for successful plant growth.

The Effects of Too Much Nitrogen in Plants

What's the function of Nitrogen (N) in plants?

Nitrogen is a very important and needed for plant growth. It is found in healthy soils, and give plants the energy to grow, and produce fruit or vegetables. Nitrogen is actually considered the most important component for supporting plant growth. Nitrogen is part of the chlorophyll molecule, which gives plants their green color and is involved in creating food for the plant through photosynthesis. Lack of nitrogen shows up as general yellowing chlorosis of the plant. Because nitrogen can move around in the plant, older growth often yellows more than the new growth.

Nitrogen is a key player in producing chlorophyll; this pigment absorbs sunlight for basic photosynthesis needs. Gardeners must make sure that nitrogen, one of the three macronutrients in soil, is available for root uptake by choosing the right fertilizer. Saturating a garden with high nitrogen levels, however, does not improve plant growth. In fact, it can actually harm a garden more than leaving it to its natural elemental state. Too much nitrogen in plants is apparent both above and below the topsoil. One of the main actions of nitrogen is increasing chlorophyll production; this process is done by creating bigger leaf structures with larger surface areas for the photosynthesizing pigment. Excess nitrogen fuels fast foliage growth so that your garden has an appearance of a jungle gone wild, but other plant growth suffers as a consequence.

Nitrogen N is among the vital elements needed for the survival of living things. Nitrogen is chemically reacted with other compounds such as ammonia, nitric acid, organic nitrates and cyanides to form unique compounds with totally different chemical and physical properties. Since plants cannot use or take nitrogen directly from the atmosphere, uptake is through nitrogen forms that include ammonium and nitrate. Importance of Nitrogen to Plants. Nitrogen is a paramount element for plants since it is a core component of many plant structures and for both their internal and external metabolic processes. Plants are required to manufacture the complex molecules through metabolism activities to survive by use of minerals from the soil that contain nitrogen such as nitrate ions. Plants too, like animals, need some important macro and micro nutrient elements including nitrogen, oxygen, hydrogen and carbon to keep them healthy.
