The problem of soil salinity is due to regular use of nutrient solution (fertilization) in greenhouse as well as by use of reclaimed water for irrigation purpose due to the limited supply of fresh water, especially in arid and semiarid areas of the world. In the present context, salinity is becoming a major challenge in India where availability of good quality water is an important issue in wake of increasing population and urbanization. Moreover the availability of good quality land is a major concern when pressure on land is increasing due to the intensification of cropping system in the context of food
Plants that were involved in the Columbian Exchange had an affect on the culture and state of economy with both the New and Old worlds. Many new plants were discovered in the Americas which included sunflowers, peanuts, chili peppers, tomatoes, beans, avocado, squash, sweet potatoes, chenopods, cacao, cassava and maize. The two plants that turned out to be of most significance were maize and potato. Maize played a key role in the Amerindian diet due to it being able to be stored for an unlimited period of time. What made the potato an important part of the diet was that it provided a valuable source of nutrients as well as being a valuable source of energy.
“The plains flood when the river rises, and is blessed with the riches that brings people merriment.” ( Egypt Mesopotamia Comparison Essay, page 1). For the majority Mesopotamia and Egypt were both agricultural civilizations. Due to the geographical features, life from these two civilization were crucially rely on their rivers. However, the Nile were far more significant to the Egyptians than the Tigris and Euphrates do to Mesopotamia. Although they all shared the same demandings but they were exceptional vary from one another in many ways.
The Silk Road was also significantly more difficult to travel across than the Mediterranean Sea Trade Complex. To travel the Mediterranean Sea Trade Complex you could just travel by boat, but the Silk Road was a challenge, that some hired others to take for them. You couldn’t take a boat across the Silk Road, so you would have to travel through deserts and rough terrain, proving difficult to last in, with the chance of a bandit robbing you, sandstorms, starvation or thirst. With all the deaths occurring on the Silk Road, it definitely left a huge impact on the civilizations there, by lowering population, distressing family members, and civilizations falling apart as a result of their leader dying. Size, spreading of cultures, and the deaths of many are all things that cause the very similar Silk Road and Mediterranean Sea Trade Complex to differentiate.
It is true that, some aspects show the benefits of genetically modified food. Firstly, there are some pros for farmers. For example, GMF is boon for farmer who land or soil is not fertilize because genetically engineered food or crops can be grown at land which leading to a shortage of water, critical climate changes (Bawa & Anilakumar 2012). According to Ayres (2011), GM crops increase yields. Hence, farmers more gain to sell and higher profits.
The river allowed the soil on the riverbanks to be enriched with nutrients, thus allowing the Egyptians to develop agricultural practices and grow numerous crops. . The river also allowed the Egyptians to bathe, travel, catch fish and drink the water. This then resulted in a lacklustre chance of famine from occurring. The Ancient Egyptians constructed their own dwellings by creating their properties out of mud-bricks, using materials provided by the rich soil of the river Nile.
Thhn Is provided them with important materials that initially would not have been accessible. The Aksum trading center, however, used the disadvantages of their land to their advantage. The hilly land was often transformed to terca e farming. This combated the unfarmable land. This allowed the growth of important crops that were later used to trade, like wheat and barley.
According to Mishra (2008), soil pollution is any changes of soil either physical or chemical which causes its use to alter or renders and does not give any advantages to use without treatment. Soil is important to human being because it have many advantages in agriculture, industrial site, recreation, housing and food production. Soil cannot be replaced with other thing which makes it precious to any country and it takes time to produce new soil. The presence of man-made wastes are the major factor that leads to soil pollution. Chemicals such as pesticides and fertilizers are popular in agricultural industry due to higher demand for the food grain production.
Some industries related to agriculture are provided the jobs to the people. But some factor which are decrease the yields of crop. And one of the most effected factor is weeds, weeds interference is one of the most importance factors to decrease the yields of various crops. Weeds are very common, dominated and wide spread in the crop fields. Weeds present in crop fields that compete with crop plants for light moisture and others essential nutrients.
Over the last few decades, the use of modern technology and the quest for sustained agriculture for growth and development has made it possible to discover, isolate, and introduce several important agricultural traits in cultivated crops. This has led to the discovery of the GM technology. The main advantage of the application of this technique is that it shortens the time of crop development and improves the certainty of the outcome, compared with conventional crop development methods such as crop breeding”. GM crops have been tested to resist certain pests, tolerate drought, and contain additional nutrients, such as rice with extra vitamin A. Although many Ghanaian farmers embrace GM crops because of its high yields, some consumers are doubtful of GM foods and refuse to purchase them.
