What Are Nutrients Affect Plant Growth?

Does different color light effect plant growth     Without light, plants would die. The process by which plants  live through the light  is called photosynthesis. Photosynthesis takes place within a plant; cells called Chloroplasts gather and store energy from sunlight and converts it into sugar for the plant to use.  While the effects of natural light on plant growth is known; filtering light different color filters effects the plant’s growth as well.

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.

In agriculture, soil can cause limitations to plant growth through (a) depth, stoniness, texture and structure which together can influence the amount of water which can be held in the profile and the ease with which roots can penetrate and (b) the availability of nutrients (Rowell, 1994). There are four main constituents of soil: mineral matter, organic matter, air and water (Fig. 1.1).

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

Nutrients that are obtained from the soil from plant roots are nitrogen, Phosphorus, Potassium, Sulfur, Magnesium, Calcium, Iron, Boron, Manganese, Zinc, Molybdenum, Copper. These twelve elements that are obtained from the soil are called mineral nutrients which are then split into more groups; primary, intermediate and micronutrients (Essential Nutrients, n.d.). Primary nutrients are called by its name because they needed and are found in the most amounts. Primary nutrients include nitrogen, phosphorous and potassium. The intermediate nutrients are sulfur, magnesium and calcium which are found less in soil than primary nutrients. Primary and secondary nutrients are called macronutrients. Iron, boron, manganese, zinc, molybdenum and copper are called micronutrients because they are needed in very small amounts. So small in fact that they are needed in parts per million, where 10000 parts per million is 1% of the plants intake (Essential Nutrients, n.d.). This doesn’t mean that the plant won’t grow as well without it though, these nutrients can still be essential to maximum growth spurt (Essential Nutrients,

While experimenting with the green beans, the seeds exposed to the organic plant food germinated within five days of the experiment and the seeds exposed to the chemical plant food germinated within six. The seeds that acted as the control had been expected to grow the least, however, it was surprising that they did not grow at all. Both the chemical and organic fertilizers proved to have positive results on the plants. It was also unexpected when the seeds exposed to the chemical plant food surpassed the height of the other experimental seeds after being shorter. The predicted reason for the increase in growth with seeds given Miracle Grow was because chemical fertilizers automatically store up the nutrients and disperse it constantly throughout

Plants are the back bone to earth; they are indispensable to being able to survive. They provide the earth with oxygen and absorb carbon dioxide. They are vital to human well-being as they provide the earth with nutrients, help with the water cycle and are essential for food supply. Plants provide all the energy for the ecosystem, as they can get energy directly from sunlight. They use a process called photosynthesis to use energy from the sun to grow and reproduce. (North western projects, Unknown) Plants also obtain nutrients from the soil in which they growth in. By using photosynthesis plants obtain most of their oxygen and carbon from the air and hydrogen is obtained from the water in the soil. (Victorian Agriculture, 2015). If salt water is absorbed in soil, it can stay in the soil for a long time. This can either be positive or negative depending of the amount of salt in the soil.

Inorganic phosphate (Pi) is a key nutrient for plants and it is involved in a myriad of metabolic processes and functions that allow their growth and development. Since it is such an important nutrient its uptake, transport, storage and usage are tightly regulated. Never the less the reduced availability of Pi in the ground is a mayor limiting factor. When phosphate starvation occurs the plant has to adapt to survive. Such stress triggers a distinct phenotype in the root such as an increase in root hair length and density, as well as an increase in the ratio root/shoot and proliferation of lateral roots. The changes in root architecture are also accompanied by changes in metabolic processes such as photosynthesis, glycolysis, carbon fixation,

Plant growth is dependent on environment factors and the activities of the meristematic tissues after germination (Dunlop et al, 2010). Some environmental factors that will affect plant growth are soil pH and external stimulus. Most plants can only grow well within a narrow range of pH values; 6-8 (Dunlop et al, 2010). Any soil that is more acidic or basic will result in poor or no plant growth. Phototropism is the growth response of a plant to light due to an unequal distribution of auxin (Dunlop et al, 2010; Tucker, 2006). This causes the plant to grow towards the light source and the cells on the side opposite to the light elongate. Dunlop & Tucker state that this results in the stem curving towards the direction of the light.The meristematic

Water is the most abundant resource on the planet and is one that is vital to all living organisms. Plants especially depend greatly on water and contain structures in their body in order to use the water efficiently. Water relations is a research field that deals with investigating how environmental factors affect the plant’s usage of the water (Bot 201L lab manual, 2016). A study was conducted to see how low water in the soil affected the uptake of water in Alfalfa leaves and if it had any effect on the plant’s photosynthesis rate. (Abid et al, 2016). It was found that there was a correlation between the photosynthesis rate and the amount of water the leaves would uptake since the stomata on the alfalfa leaves would remain closed (Abid et al, 2016). Since the stomata would close more

Plans can have two different kinds of growth: indeterminate and determinate. Plants that grow all throughout their lifetime and never reach a size limit have indeterminate growth. Most plant organs have determinate growth, which means that they stop growing after they reach a certain size. The reason that plants grow without ceasing is the presence of permanently dividing unspecialized tissues called meristems. There are two types of meristems: apical and lateral. Apical meristems are located at the tops of shoots and roots, and they enable primary growth, which is growth in length (Campbell et al., 2014). In primary growth, shoots grow upwards to try and absorb more light, and roots grow deeper into the soil to increase the surface area of the plant. Lateral meristems allow the plant to grow in thickness by a process called secondary growth. Herbaceous plants grow predominantly through primary growth, whereas woody plants use both primary and

The purpose of this lab is to see if black tea helps as a natural fertilizer to enhance the growth of the radish plants. In order for a seedling to grow into a healthy mature plant, it must have nourishments like water and nutrients. Tannic acid and nutrients are some of the nutritional ingredients in black tea, when these nutrients are added to soil it becomes a more habitable place for the seedlings to develop into plants. Tea leaves also have nitrogen in them, nitrogen is a vital nutrient for plants to grow.

Nutrient limitations such as phosphorus (P), a prime abiotic stressor, can limit plant growth and other developmental processes. P deficiency has been shown to decrease the rate of photosynthesis, tiller production, leaf size, biomass, and the light saturation point (Halstead & Lynch, 1996; Yan et al., 2015). By contrast, it has been observed that M. vimineum tends to have a high soil phosphorus levels in comparison to other species in the shaded understory of forest. One study conducted by McGrath & Binkle (2009) investigated three forest sites where M. vimineum is abundant and found that in dense stands, phosphorus concentration was greater in M. vimineum litter than in other species litter. Taking into account that the response of M. vimineum to shade tolerance depends on the increased growth of tillers and leaf size, the capture of light from sunflecks, and increased rates of photosynthesis, all of which are heavily influenced by higher P availability, it’s reasonable to assume that the amount of available P dictates shade

5. We observed that corn plants and pea plants (Pisum sativum) grown under the same conditions grew differently: under conditions that were often dry, the corn managed to maintain a larger percentage of green leaf area relative to brown/dry leaf area. Investigate the photosynthetic systems used by corn vs. that used by peas. Compare and contrast these two photosynthetic systems, especially with respect to water availability and usage.

The plants that grow in saline soils have diverse ionic compositions and a range in concentrations of dissolved salts (Volkmar et al., 1998). These concentrations fluctuate because of changes in water source, drainage, evapo-transpiration, and solute availability (Volkmar et al., 1998). Due to these varying conditions, plant growth depends on a supply of inorganic nutrients, and this level of nutrients varies in time and space (Maathius and Amtmann, 1999). Either extreme condition concerning nutrients results in deficiency or toxicity in plants, and this is demonstrated by salt tolerance (Maathius and Amtmann, 1999). These conditions vary according to the plant species and growth conditions. Little is known about the genetic basis for diversity of salt tolerance in plants, and this could be partly explained through the definitions given for salinity.
