Conventional agriculture involves the use of large portions of land and excess amounts water to grow crops. The improper use of soil and water resources for agricultural purposes leads to environmental degradation on many levels . Soil erosion and nutrient depletion have become a widespread result of improper soil care and inefficient irrigation techniques. Hydroponic farming serves as an alternative to conventional agriculture and is a resource efficient and environmentally friendly way to produce crops, in terms of both land and water conservation. This alternative farming practice has great potential to lessen the environmental impacts caused by water and soil misusage in conventional farming.
Approximately thirty-six percent of the e arth’s agriculturally feasible land is already used to grow crops (Crop Production). As the world’s population steadily increases, more pressure is placed upon increasing the efficiency of land used for agriculture and on increases in net production. Potential agricultural land is lost everyday due to urban sprawl as population density increases throughout the world (Brown, 132). Genetically modified crop varieties are reaching their threshold of potential yield increases, since plant breeders have already exploited the most obvious techniques to genetically increase yield (Brown, p. 132). This creates a cap on how many people can be fed with current land usage and yields. Destructive farming techniques play a large role in soil quality degradation. Conventional agricultural techniques such as monocropping and intensive tilling reduce the quality of the soil by depleting nutrient contents and increasing bulk density. As these issues persist, soil health continues to decline rendering the land u...

... Hydroponic farms can be constructed in places of poor soil quality, which excludes soil texture and other properties from being an issue in plant growth. These areas could greatly benefit from hydroponic farming. Abandoned lots in urban areas serve as perfect places to build greenhouses. These farms allow for fresh produce at a closer distance to dense populations, and reduce the energy expended on produce transportation. Hydroponic systems can also be built indoors with complete artificial lighting, which allows for crop growth year round.
Water and soil conservation issues will only increase in severity as the e arth’s population increases and as water resources become more limited. Hydroponic farming serves as one sustainable solution to these issues and has great potential to lessen the negative impact of conventional agricultural techniques.

A Brief History of Irrigation Essay

- In 6000 BCE Irrigation began Mesopotamia (present day Iraq) using the water of the flooding Tigris/Euphrates rivers. The flood of water only occurred once a year From July through December.

Essay on Biological Resources : The Bioprocessing Of Beer

- The Bioprocessing of Beer Biological resources play an important role in the production of agricultural commodities as well as some of the most widely consumed products in the world such as beer. Beer is thought to be one of the oldest fermented beverages in the world (Arnold, 2005) and brewing industries which consist of several multinational national and smaller companies have become main resources for its availability globally (Chrzan, 2013).The preparation of the beverage consists of bioprocesses which involve the saccharification of starch most commonly derived from malted wheat and barley, and fermentation (Khattak et al., 2012) of the resulting sugar due to yeast....   [tags: Brewing, Beer, Malt, Enzyme]

Essay on Effects of Agriculture on the Environment

- Effects of Agriculture on the Environment Introduction:      Agriculture has changed dramatically, especially since the end of World War II. Food and fibre productivity rose due to new technologies, mechanization, increased chemical use, specialization and government policies that favoured maximizing production. These changes allowed fewer farmers with reduced labour demands to produce the majority of the food and fibre. Humans, like all other species, exploit their surroundings for the resources they need to survive....   [tags: Agricultural Environment Nature Essays]
