Hydroponics essays

Hydroponics essays Growing plants hydroponically is the method of growing plants in chemical solutions opposed to the traditional style of growing plants in soil. With the continual increase of industrialised society, large farm are becoming drastically less common and growing plants hydroponically is fast becoming one of the most popular methods of farming. When growing plants hydroponically they are easily monitored and any nutrition lacking can be seen and immediately added. In this experiment tomato plants were grown in several different solutions over a four week period in order to determine what nutrients plans need and why. There were nice different chemical solutions, these were Iron, -Magnesium, -Calcium, -Potassium, -Phosphorus, -Nitrogen and sulphur. Full nutrients and distilled water were also used to contrast the extremities of all nutrients and no nutrients. It is known that plants with an iron deficiency commonly have small leaves that do not remain green. These characteristics were apparent in the plants viewed as they had small yellow leaves. The plant in general looked considerably healthy with plant roots and stems reaching average lengths. The common trend of plants lacking sulphur is purple veins of lower leaf surfaces and petioles are commonly more vertical. These same results were apparent in the plants viewed however these characteristics did not appear until week four when the stems began to show a purple colour and the plants leafs strangely appeared to grow vertically up. The reason it did not show these characteristics until week four may have been because the plants had retained a fair amount of sulphur when originally in the soil to not become sulphur deficient immediately. Throughout the duration of the experiment sulphur deficient plants were considerably larger then most of the other plants viewed. ...
