Sample Essay on Factors Affecting Plant Growth

Plant Growth

Plants play a major role in supporting the environment and life in general. Without them, life would be simply a bed of rocks without anything much to smile about. For them to growth, there are quite a number of factors that come to play. There are those factors that can support growth of plants and others that may inhibit the process. The common factors affecting plant growth can be categorized into nutritional and environmental factors. Nutritional factors include water and nutrients while environmental factors comprise of light, temperature, relative humidity, soil, carbon dioxide and humidity.

In terms of nutritional factors that affect plant growth, it should be noted that the presence of adequate nutrients can support the growth of healthy plants. On the contrary, when there is no sufficient nutrients, plants will wither and appear weak just like it occurs even in humans. Plants require more macronutrients like nitrogen, potassium, magnesium, phosphorus, calcium and sulfur compared to micronutrients that include iron, zinc, manganese, boron, copper, molybdenum, chlorine and cobalt.

Water is also another nutritional factor that affects plants’ growth in that; it is one of the most essential requirements. It is with water that processes like photosynthesis, respiration, transportation of plant nutrients and transpiration take place. This means that without water, plants will automatically die.

Various sources including natural and artificial can be used for the provision of light to plants. For plants to be able Image 2to generate leaves and even flower there has to be light. While natural light is the best for growth of plants, artificial can also be adjusted to certain limits to aid the process. However, the requirement of light varies from one plant to another since there are those that require too much light and others that require less. Just like it is with water, the absence of light can significantly hamper growth of plants and produce unpleasant results.

Temperature is yet another factor that can also influence the growth of plants. The temperature of the surrounding and also that of the soil greatly influence the way in which a plant grows. It is always required that there has to be optimum temperature for processes like respiration, photosynthesis, germination and flowering. Even though there are plants that can survive in areas experiencing high temperatures, it can lead to withering of many varieties of plants.

For plants to grow well, it is required that there needs to be soil with proper humidity as well as the right measure of minerals and nutrients. However, the type of soil and nutrients that are required for growing a particular plant depends on its species. The ideal PH balance, which determines the alkalinity or acidity of soil and presence of certain chemicals therein are also crucial in the growth of plants.

For plants to grow well, they also require carbon dioxide. In fact, plants can utilize up to 1500 parts per million of carbon dioxide. Carbon dioxide can be provided for plants naturally from the atmosphere or artificially by injection in greenhouses.
