Plants essays Fertilizer has played an important role in the health and growth of plants since the beginning of time. Fertilizer has helped farmers and million of people across the world to grow healthy plants that they could sell to the public. It does not have to be sold in bags to be considered fertilizer. Even a banana peal is fertilizer because it promotes the growth and helps improve the health of the plant. For plants to have a successful life they need to be supplied with various types and amounts of nutrients which is sufficiently provided by fertilizers (Secrets to great soil, 1998). There are two types on nutrients that are absorbed and used by plants(Improving the soil, 1996). Those two are macronutrients and micronutrients(Improving the soil, 1996). Micronutrients are the types of nutrients that are used less by plants because they are not as essential for good health(Improving the soil, 1996). They help the plant grow healthy, but the plant can live without them. Some types of micronutrients include calcium, magnesium, sulfur, boron, and manganese (Easy Compost,1997). Plants use macronutrients more frequently than micronutrients (Espoma, 2002). They are necessary and much more essential for the growth of plants than micronutrients (Espoma, 2002).. Macronutrients unlike micronutrients are extremely important for the plants life(Improving the soil, 1996). Without them a plant would most certainly die (Espoma, 2002). . These nutrients are in high demand. They are nitrogen, phosphorus, and potassium(Improving the soil, 1996). Phosphorus is one of the most vital nutrients that a plant needs(Secrets to great soil, 1998). It has a great amount of important role that it fulfills that helps maintain the plants health. One essential role that phosphorus plays in the development of plants is the improvement of its immune system(Secrets to great soil, 1998).. Just like humans, plants can also get ill. That is just one of the many...

The History of Swimming Pools

The History of Swimming Pools Swimming pools, at least man-made watering holes for bathing and swimming, go back at least as far as 2600 B.C.E. The first elaborate construction are probably The Great Baths of Mohenjodaro, an ancient and elaborate bathing site in Pakistan made from bricks and covered in plaster, with terraced decks that wouldn’t look out of place in a modern pool landscape. Mohenjodaro probably wasn’t used for general lap swimming, however. Scholars believe it was used in religious ceremonies. Ancient Pools More man-made pools surfaced throughout the ancient world. In Rome and Greece, swimming was part of the education of elementary age boys and the Romans built the first swimming pools (separate from bathing pools). The first heated swimming pool was built by Gaius Maecenas of Rome in the first century BC. Gaius Maecenas was a rich Roman lord and considered one of the first patrons of arts- he supported the famous poets Horace, Virgil, and Propertius, making it possible for them to live and write without fear of poverty. Growth in Popularity However, swimming pools did not become popular until the middle of the 19th century. By 1837, six indoor pools with diving boards were built in London, England. After the modern Olympic Games began in 1896 and swimming races were among the original events, the popularity of swimming pools began to spread According to the book Contested Waters: A Social History of Swimming in America, the Cabot Street Bath in Boston was the first swimming pool in the U.S.  It opened in 1868 and served a neighborhood where most of the homes did not have baths. In the 20th century, a number of leaps in science and technology took swimming pools to a new level. Among the developments, chlorination and filtration systems that delivered clean water into the pool. Prior to these developments, the only way to clean a pool was to remove and replace all the water. Technological Advancements In the U.S. the pool business expanded with the invention of gunite, a material that allowed faster installation, more flexible designs, and lower costs than previous methods. The post-war rise of the middle-case, coupled with the relative affordability of pools accelerated pool proliferation even further. There were even less expensive options than gunite. In 1947, above ground pool kits hit the market, creating an entirely new pool experience. It wasn’t long before single unit pools would be sold and installed in a single day.
