He was certain that adding the extra fertilizer would produce a massive crop few when it came time to harvest in a few months. Zeke didn't tell his father about the extra fertilizer he added to the grapes, wanting to see his father's tremendous surprise over the size of the harvest to come. As expected, the rain started Friday afternoon. Zeke was out of bed early on Saturday morning and headed out to the vineyard expecting to see vibrant blossoms on the grape vines due to the fertilizer "boost he had given them. His stomach dropped a bit as he stared out at a field of sickly looking grape vines. Their leaves were pale and slightly wilted. Page 2 of4

Explanation / Answer

The case study given here is the result of Overfertilized plant.  Here Zeke added extra amounts oif Magnesium, Potassium and Phosphate in order to have a massive crop yield. The analysis for the given question can be done as:

1. OSMOSIS:  

Osmosis is the diffussion movement of a solvent from a high concentrated solute to a lower concentrated solute through a semipermeable membrane. In this case study, Overfertilization of the plants using Magnesium, Potassium and phosphate resulted in the pale and slightly wilted condition of the plants as the plants intook these chemicals into theri system by Osmosis.. Excess fertilizers resulted in Fertilizer Burn. Fertizer Burn is the result of applying excess fertilizer to plants or applying fertilizer to wet foliage. In this case Excess fertlizer application had caused the roots to "burn" and it lessened the moisture intake. The burned roots become weakened against disease and other factors. This results in yellowing or brown discolouring of the palnts. White, yellow or brown patterns appear following the pattern of fertlizer spread on the plant. The effect will be seen in a day or if a slow-release fertilizer is applied it takes a few weeks for the symptoms to appear.

2. Zeke could get out of this problem by Leaching.   Leaching is the process of movement of nutrients down through the soil by percolating water.  Leaching will wash out the excess fertilizer from the leaves and root and the plants will recover their normal growth. Not only that, the discoloured withered leaves, dying foliage and infected roots should be removed away.

3. Normally plants are just watered without solutes. Generally plants lose water due to Transpiration in the form of water vapour. It is important that the soil should remain loose and not compact. Watering the soil helps the roots to abosrb water quickly from the loose soil. While watering with normal water or H2O the plants absorb the water through roots in the soil and transport it to the entrie plant via xylem adn stored in vacoules. The Turgor Pressure of the vacoules is applied to the rigid cell wall and the plants maintain their structure. When a plant is healthy simple watering is enough for its healthy growth and normal yield. Over watering leads to stagnation of water leading to over-saturation around the roots and results in dying of the plant which should be avoided.

4. Plants are capable to thrive harsh conditions of climate, pollution or drought within their limits. LEVITTdescribes it as "hardiness of plants" which includes resistance to freezing, chilling,, high temperature ,drought, alkalinity and acidity. Strilking alterations are seen in the cellular and sub-cellular levels as a response to environmental conditions. Adaptation occurs from the plant organ down to the cell and cell organells. And Photosynthesis provide them with their source of energy to thrive these chemical conditions. They try to reduce their uptake of salts and increase efflux or salt inclusion via releasing salts via salt glands and sal-tolerant enzymes and thus acquires salt tolerance mechansims. This is how the plant thrives in this sort of environment.
