Introduction

Water is one of the most essential resources for plants to grow and survive. Every plant requires a different amount of water, depending on factors such as climate, soil type, and genetics. Some plants have evolved to efficiently use water, while others require a lot of it to thrive. In this article, we will explore what plants drink a lot of water and why they need it.

Plants that drink a lot of water

1. Rice: Rice is a water-loving plant that requires a lot of water to grow. Rice paddies are flooded with water to keep the soil moist and support the growth of the rice plant. It can take up to 3,000 liters of water to produce 1 kilogram of rice. In countries such as China and India where rice is a staple food, the high demand for rice also requires a lot of water.

2. Corn: Corn is another crop that requires a lot of water to grow. On average, it requires about 500-800 mm of water during its growing season. Corn is commonly grown in the midwestern United States, where water availability can be an issue. Farmers need to use efficient irrigation methods to ensure that the corn gets enough water to grow.

3. Sugarcane: Sugarcane is a tropical crop that requires a lot of water to grow. It needs approximately 1,500 mm of water during its growing season. Sugarcane is commonly grown in countries such as Brazil, India, and Thailand, where water availability is generally not an issue.

4. Willow trees: Willow trees have a reputation for being water-loving plants. They require a lot of water to grow and are commonly found near lakes, rivers, and other sources of water. Willow trees are often used for phytoremediation, a process that uses plants to remove pollutants from the soil and water.

Why plants need a lot of water

Plants require water for several reasons. Firstly, water is necessary for photosynthesis, the process by which plants make their food. During photosynthesis, plants absorb water and carbon dioxide from the air and use energy from the sun to convert them into glucose and oxygen. Secondly, water is essential for transporting nutrients and minerals from the soil to the rest of the plant. Without water, the plant would not be able to absorb these essential nutrients. Lastly, water also helps to keep the plant turgid, which is necessary for supporting the plant's structure and preventing wilting.

Conclusion

In conclusion, some plants require a lot of water to thrive, while others have evolved to use water more efficiently. Understanding which plants require a lot of water is important for farmers, gardeners, and policymakers. It can help them make informed decisions about water use and conservation in areas where water is scarce. By using efficient irrigation methods and planting water-efficient crops, we can ensure that we have enough water to meet our needs while also protecting the environment.
