[31] The opposition to organic agriculture believes that these negatives are an issue with the organic farming system. Around the world, at least one breed of livestock disappears each week as farmers focus more and more on standardized hybrids. Chlordane, one of those Persistent Organic Pollutants (POP), was banned by the USDA in 1983. In this way, deforestation exacerbates climate change. The most significant climate change associated with agriculture is brought about by methane, nitrous oxide and carbon dioxide, all of which are greenhouse gases released into the Earth’s atmosphere from farming. 5. Among some GMO critics and skeptics, there is an oft-stated belief that organic farming is friendlier to the land and the environment. Yes, the use of biotechnology, GMOs or gene editing to develop antigens for treatments including vaccines are part of the solution. Nutrient cycling efficiencies within farming systems have important implications for water resources. [23] Viewpoint: GMOs don't boost crop yields? When plants are more susceptible to disease and pests because of the absence of bacteria and fungi defenses, disease and pests are able to spread more quickly. (1997). Furthermore, some of the research that has been done on pesticides is kept confidential by chemical companies. (2013). Like fresh water, our oceans are also being contaminated. Organic matter and compost are food sources for worms and are essential to their survival. It took 120 days for the populations to return to normal rates comparable to the control (Pandy & Singh, 2004). The use of plastic mulch for vegetables, strawberries, and other row and orchard crops exceeds 110 million pounds annually in the United States. Regardless, the source of nutrients and the success of plant growth is largely associated with biology in the soil. When aggregate stability is high, it means organic matter content, biological activity, and nutrient cycling in soil are at healthy levels (Andrews & Wander, 2008). The environmental impact of agriculture is the effect that different farming practices have on the ecosystems around them, and how those effects can be traced back to those practices. Retrieved October/28, 2015, from http://soilquality.org/indicators/aggregate_stability.html. Many of the heritage catalogs will show vintage pictures that make it clear – we have lost an incredible range of fruits and vegetables that our ancestors enjoyed but which we will never taste. Similar to phosphorus, potash is mined from the earth. In organic agriculture, phosphorus is added to soil in the form of manure while in conventional agriculture, phosphorus in added through fertilizers derived from mined phosphorus. According to the Washington Post, he has challenged “the incorrect notion that humans are smarter than Mother Nature, and we need man-made answers. Do you believe that only chemical-based conventional farming can feed the world? Increase in population resulting in more demand for fuel wood and timber. Other livestock as poultry, fish, ... has a far lower impact. Soil ecology: What lies beneath. What began as a small scale, environmentally conscious practice has now become just as industrialized as conventional agriculture. This creates a positive feedback loop in the soil system with fertilizer use. All living things require nutrients. Fertilization practices and soil variations control nitrogen oxide emissions from tropical sugar cane. (e) Decline in underground water due to over exhaustion for high water using crops, increase in cropping intensity and increase in cultivated area especially is northern part of the sweet water zone. ! Bengtsson, J., Ahnstrom, J., & Weibull, A. Conversely, without using pesticides, organic agriculture, while still using row cropping to some extent, usually increases species richness with 30% higher levels of species compared to conventional agriculture (Bengsston et al, 2005). (2005). However, this finding was limited to organic agriculture on smaller sized plot and field scales while effects were less significant for larger agricultural areas. (UNFAO, 2013)", Figure 3: No-till farming around the world. The ‘cides are not intelligent. Moreover, the views expressed here do not necessarily represent the views of Inquiries Journal or Student Pulse, its owners, staff, contributors, or affiliates. [Video/DVD] Mill Valley, CA: Lily Films. The references used in this paper are diverse and numerous in order to present a broad comparison between conventional/monoculture agriculture and organic agriculture. Furthermore, pests cannot cause as much damage in organic systems because there are more predators that can keep the level of pests in balance. "Effects of Conventional and Organic Agricultural Techniques on Soil Ecology." Over longer periods of geologic time, these rocks will become exposed to terrestrial environments and once again repeat the process. Welcome to EconomicsDiscussion.net! While there has been a minor success with this, there is also the problem of how long the plastic takes to degrade, as many biodegradable products take a long time to break down.[28]. The direct effect of high use of dangerous pesticides is on human and animal health. To inform the public about what’s really going on, we present the facts and challenge those who don't. Conventional farming grows a single crop year after year, usually vast fields of that one crop, which depletes the soil of micronutrients. The reduction of saturated hydraulic conductivity in soil also results in increased water runoff and erosion. As may be seen from Table. Conventional and organic farming methods have different consequences on the environment and people. Retrieved November/10, 2015, from http://www.nrcs.usda.gov/wps/portal/nrcs/detailfull/soils/health/biology/?cid=nrcs142p2_053868. Tim Barker, managing editor for the Genetic Literacy Project, is a veteran reporter, most recently with the Orlando Sentinel and St. Louis Post Dispatch. [25] Common attributes of soil degradation can be salting, waterlogging, compaction, pesticide contamination, a decline in soil structure quality, loss of fertility, changes in soil acidity, alkalinity, salinity, and erosion. For 2014 in the US, agricultural scientist and consultant Steve Savage examined USDA data and found organic corn faced a 35 percent shortfall; soybeans 31 percent; and cotton 45 percent. [2], Most of the methane emissions result from the use of livestock, in particular ruminants such as cattle and pigs. Colorado state university: The living soil Retrieved November/14, 2015, from http://www.ext.colostate.edu/mg/gardennotes/212.html. In addition to harming the biology of the soil, fertilizers have been found to affect the very chemistry of soil. Landslides caused by rains and flowing water in hilly areas and deforestation, overgrazing and faulty cultural practices in the forest and other plain areas expose the soil to water and wind erosions. Disaster interrupted: Which farming system better preserves insect populations: Organic or conventional? Badgley, C., Moghtader, J., Quintero, E., Zakem, E., Chappell, M. J., Aviles-Vazquez, K., et al. ILRI, 1989, Effectiveness and Social/Environmental Impacts of Irrigation Projects: a Review. Smith, M., Hartnett, D., & Rice, C. (2000). Studies by Alvarez and Steinbach (2009) showed that soils that are not tilled after harvest or before planting (no till) can have 50% higher penetration than plow tillage. Aselage, J., & Johnson, D. T. (2009). No till, or minimum till soils tend to reduce the loss of earthworm biomass. Under no till systems, arbuscular mycorrhizal survive at higher rates. The study showed increase richness and heterogeneity of birds, insects, plants and soil organisms.
