What Are Three Things Plants Need to Live?

 

Plants, like other organic matter, require certain substances in order to grow. Understanding a plant’s essential needs helps in growing healthy, strong plants. The three basic requirements for plant growth are water, light and nutrients. While these things are important to plant development, they should be given in moderation. Too much of any one substance can damage or even kill a plant. Water is one of the things plants need to live.

Plant tissues comprise 80 to 95 percent water. Much of the water for plants comes from absorption of water within the soil. The moisture level of a soil directly affects the survival of a plant; should the soil become too dry, many plants will begin to dry up, wilt and even die off. Even in areas with limited moisture, such as deserts, plants still need water and have adapted ways to make the water received last as long as possible. Too much water, however, can be detrimental for plants. Allowing soil to dry out some between watering prevents damage to the plant caused by over watering.

Light is another of the basic necessities of life for a plant. Plants need light as part of the process of photosynthesis. Outdoors, and in the case of indoor plants close to windows, sunlight provides the light. In some instances, more light is needed for indoor plants. Many growers supplement sunlight by using artificial fluorescent lighting for plants.

How are Drones Changing the Future of Agriculture?

Image
Drones provide an alternative source of labor on unprecedented spatiotemporal scales. The future of drones in agriculture is also promising, as drones are being developed to act as mechanical pollinators and to incorporate smart applications, making drones a promising and affordable technology to address the challenge of growing food insecurity. Drones have mostly been associated with military practices or for recreational purposes, but recent developments, particularly in sensors and imaging processing, have broadened the scope and applicability of drones. The reduction of drone costs and the increased accessibility of technologies, occurring simultaneously to technological progress, has also further accelerated the popularity of drones, allowing drones to be used in other industries such as agriculture. Modern drones now offer a range of open-source technologies, smart sensors, and longer flight times, and therefore provide a number of benefits for agricultural practices from m

What’s Up with Agricultural Technology?

  For instance, a farmer may be interested in sustainably growing more food using less space while minimizing environmental impact. They could try vertical farming, which involves growing produce indoors on vertically stacked shelves . Vertical growers control critical environmental factors like light, humidity, and water to achieve year-long harvests , all while using 70-95% less water than traditional methods. Many people can find vertically grown leafy greens or herbs in their grocery stores today. On the other hand, maybe food safety or origin is of interest. Some companies are using block chain to track where and when food products change hands before reaching your lunchbox. We’ll cover how block chain works in a later article, but for now, note that this traceability helps companies pinpoint foodborne illness outbreaks and helps consumers determine whether that “ wild-caught salmon ” was actually caught in the wild. While technology has consistently improved farming practices

Use of Modern Technology in Agriculture Sector

Image
The most essential issue in the world today is the food supply. The demand for food has increased by more than twice the population growth rate over the past 40 years. In fact, according to a report by the Food and Agriculture Organization (FAO), about 11% of the global population, or 815 million people, are undernourished and do not have enough food for their active and healthy lives. The article talks of how modern technology has been very helpful in the agriculture sector and it is helping to produce more and better quality of food, which is, in turn, helping to sustain life . The use of modern technology in the agriculture sector is vast. It has helped farmers in various ways. The adoption of new and improved technologies has increased the production and productivity of crops . It has also helped in reducing the cost of production. The use of technology has also made the farming process easier and more efficient. The use of technology in agriculture has also had a positive
