Contour plowing is an agricultural management technique used by farmers and growers to help minimize soil erosion. Contour plowing can also be used to help manage and improve soil structure and fertility.
The process involves plowing furrows along the topography of a field, rather than straight across the land, so that the furrows form a series of parallel ridges. This helps to slow and divert the flow of runoff water, which can cause erosion and nutrient deficiencies, as well as damage soil structure.
Additionally, crop residues are left in the furrow to minimize surface soil runoff and erosion. This helps to keep soils in place and in better condition so that they can retain moisture and plant nutrients.
The use of contour plowing also helps to reduce off-site impacts by reducing the amount of sediment and nutrient runoff into nearby water bodies and wetlands. The furrows help to filter out sediment and trap of nutrients, reducing their load in runoff and therefore protecting these areas from the impact of agricultural activities.
What is a major environmental problem caused by using the agricultural practice of tilling?
One major environmental problem caused by using the agricultural practice of tilling is soil erosion. When the soil is tilled, it is disturbed and makes it easier for wind and water to move the soil particles away.
This can often leave fields stripped of nutrient-rich topsoil and cause further damage in downstream areas as the soil become concentrated in waterways. In addition, tilling can also release potentially harmful compounds stored in the soil from pesticide and fertilizer use, leading to water contamination.
Tilling can also lead to a decrease in the overall structural quality of the soil, which can then lead to a decrease in water infiltration, increased runoff, and increased soil compaction. All of these factors can have a negative impact on the local environment over time.
Which of the following methods of agricultural irrigation results in the loss of the least amount of water by evaporation?
The most efficient method of agricultural irrigation that results in the least amount of water lost by evaporation is drip irrigation. This form of irrigation utilizes a network of pipes laid out in the soil to deliver water directly to the roots of plants at a low, controlled flow rate.
The slow, steady application of water allows the soil to absorb what is needed, thus reducing the amount of water lost to runoff and evaporation. With proper maintenance and management, this method of irrigation can help increase water-use efficiency by up to 60%.
In addition, it can help reduce labor costs associated with traditional watering methods and conserve water by minimizing the amount lost to runoff.
What is an unintended environmental consequence of aquaculture?
An unintended environmental consequence of aquaculture is the potential disruption of natural aquatic habitats and species. Aquaculture operations can alter the ecosystems they are operating in, as they require large amounts of water, food, and resources to operate.
Aquaculture activities can also lead to a decrease in water quality, as water supplies become polluted with excessive nutrients, chemicals, and pathogens from fish feed and other inputs. Additionally, fish farm operations can produce noise and light pollution, which can disrupt the behavior of nearby aquatic life, as well as organisms that rely on those habitats.
Aquaculture activities can also impact biodiversity as areas can become overcrowded with farmed fish, which can overcompete with native species for resources. There is also a risk of farmed species escaping and interbreeding with native species, leading to hybridization and further unintended environmental impacts.
Which of the following will be the greatest impact on the development on the local water supply?
The greatest impact on the development of a local water supply depends on the local area in question and the existing water resources available. In many cases, the expansion of existing water sources such as a reservoir, river or underground aquifer may prove to be the best way to increase the local water supply.
This could be done through the addition of infrastructure such as pumps, dams, or increased maintenance on existing water sources. Additionally, the construction of new wells and water treatment plants could provide new sources of accessible potable water to the community.
Other possibilities for improving the local water supply include the implementation of innovative technologies such as rainwater harvesting, use of recycled water for non-potable purposes, and the adoption of water conservation and efficiency measures.
In areas where the local water supply is scarce, the sourcing of non-conventional water sources such as brackish groundwater, seawater, and polluted water can offer another option for developing the local water supply.
Regardless of the strategy adopted, each strategy should be thoughtfully implemented to ensure that it meets the community’s needs in terms of both quantity and quality while minimizing environmental impacts.
What is a major problem with conservation tillage?
Conservation tillage is a farming practice where minimum soil disturbances are made during cultivation. While this practice has a number of positive effects on the environment, some of its impacts can cause major problems.
One of the major problems with conservation tillage is that it can increase the amount of water and wind erosion of topsoil. As cultivation is reduced, less organic matter remains on the surface of the soil, which decreases the amount of vegetation that can protect the soil from being eroded by wind and water.
This can lead to significant soil loss over time, which detracts from the preservation of topsoil.
Another problem with conservation tillage is that it can increase the amount of soil compaction occurring in the soil. Since cultivation is minimal, more intensive tractor use is needed for the same operations, but it does not help to reduce soil compaction the way that traditional tillage does.
This can reduce the ability of soil to absorb water and oxygen, and can cause poor drainage and other issues.
Finally, conservation tillage can lessen the amount of organic matter that is placed back in the soil. This can cause a decrease in beneficial soil microorganisms and slow down the decomposition of crop residues.
This can decrease the amount of nutrients available for plants, possibly resulting in poor plant growth.
Overall, conservation tillage has a number of benefits, but the problems that it can cause need to be taken into consideration when deciding if it is the best farming practice for a particular situation.
How does tillage destroy the environment?
Tillage, or the process of plowing land to grow crops, is known to have a very destructive effect on the environment. The excessive land disruption can cause erosion and nutrient runoff, leading to long-term soil degradation that reduces soil health and productivity.
In addition, tillage can pollute surface and ground water with agricultural chemicals, and it can cause or contribute to the acceleration of climate change. By disrupting the soils, it reduces the number of beneficial organisms living the soil, reducing the soils’ ability to filter water and store carbon.
By disrupting soil and destroying soil structure, it can increase susceptibility to wind and water erosion. This leads to soil loss and degraded water quality, leading to increased runoff, flooding, and even desertification.
Additionally, tillage increases populations of harmful pests that can aggravate weeds, making herbicides and insecticides more frequently used, leading to higher levels of contaminants in the environment.
What is tilling What are some environmental impacts of tilling quizlet?
Tilling is the process of cultivating and breaking up the soil in a field or a garden. It is an important first step in getting soil ready for planting. Tilling can increase nutrient availability in the soil as well as facilitate drainage.
It also helps to increase the amount of air exchange between the soil and the atmosphere, which is beneficial for plant health.
However, tilling can also have significant environmental impacts. Tilling can result in increased erosion of the topsoil due to its disruption of the natural structure of the soil. This can lead to increased nutrient runoff, exposing aquatic ecosystems to potentially dangerous levels of fertilizers and other agricultural chemicals.
Additionally, tilling can cause the death of beneficial soil microorganisms, reducing the soil’s ability to retain nutrients and provide adequate water and air exchange for healthy plant growth. Finally, by disturbing the soil, tilling can release carbon dioxide into the atmosphere, contributing to climate change.
What is an important concern about the increasing use of aquaculture?
The increasing use of aquaculture is accompanied by a variety of environmental, social and economic concerns. Firstly, long-term environmental impacts of aquaculture, such as the introduction of pollutants and the spread of diseases, can cause significant harm to ocean ecosystems.
Aquaculture can also lead to the displacement of important species and habitat loss, as desirable areas are converted from their natural state to accommodate farming operations. Social concerns include the displacement of local populations and the disruption of traditional lifestyles, as well as an increase in poverty and hunger due to competition for limited resources.
Additionally, economic concerns arise due to the high cost associated with high-tech aquaculture production, which keeps smaller producers out of the market, leading to a lack of competition. Without adequate regulations in place, aquaculture operations may be operated in an unsustainable manner, potentially leading to a collapse of aquaculture-dependent industry.
In conclusion, the rise of aquaculture necessitates an increase in research, monitoring and regulation in order to sustainably manage the industry and avoid potential environmental, social and economic harms.
What are four negative impacts of aquaculture?
Four of the negative impacts of aquaculture include:
1. Pollution: Aquaculture produces a lot of waste, which can end up polluting the water in which it is taking place and the surrounding environment. The waste generated can alter water quality, which can degrade aquatic habitats and threaten natural populations of fish, plants, and other organisms.
2. Diseases: Aquaculture can spread a number of diseases, as organisms are often kept in close quarters and are exposed to a wide range of potential infection sources. Diseases can spread rapidly amongst farmed fish and shellfish, affecting not just the farmed creatures, but also wild populations, with potentially devastating consequences.
3. Competition with Wild Populations: Farmed fish consume supplies of food that could have been consumed by wild populations, which can lead to increased competition. In addition, farmed species may also escape into the wild, competing with and outcompeting native populations.
4. Land Use: Aquaculture can also have an impact on land use. Farms need to be built or constructed to house the fish and shellfish, often taking up valuable land that could be used for other purposes.
In addition, some forms of aquaculture may increase nutrient levels in surface water, leading to algal blooms, which can further harm water quality and aquatic life.
What is an example of a negative side effect quizlet?

The all-encompassing platform may be a bit much for some users and can cause sensory overload and mental fatigue trying to manage all the studying options at once.
Additionally, it may be difficult at first to navigate the user interface and it may be time consuming to properly set up activities and material. As much as Quizlet can be a useful studying tool, there can be a learning curve that can cause users to become frustrated before they even start studying.
Which of the following describes an environmental advantage of urbanization?
Urbanization has numerous environmental advantages. Firstly, urbanization is often accompanied by better public transportation which can drastically reduce overall transportation emissions. As people rely more on public transit, they use fewer personal vehicles which decreases air pollution, traffic congestion, and energy consumption.
Not only does public transit reduce reliance on fossil fuels, but it also increases the efficiency of personal commuting since the transportation takes the most efficient route.
Urbanization can also reduce sprawl, which is the growth of city boundaries outward without considering the consequences that it may have on people and the environment. When cities expand erratically outward it often increases air pollution, as well as reduces natural habitats.
By curbing sprawl, urbanization ensures that growth is structured, thus other lands may be preserved and resources more conserved.
Additionally, urban areas are often better equipped to deal with the impacts of climate change due to their concentration of resources and technology. This includes innovations such as green roofs and urban forests.
These systems introduce vegetation into the built environment, which is not only aesthetically pleasing, but also important for carbon sequestration, temperature regulation and rainwater management.
Overall, urbanization offers a number of environmental benefits as it provides cities with the opportunity to create sustainable development measures that reduce energy consumption, air pollution, and sprawl while introducing resilient strategies to combat the impacts of climate change.
What environmental problem reduces the ability of soil to store water and support plant growth?
Soil degradation is one of the biggest environmental problems that reduces the ability of soil to store water and support plant growth. Soil degradation is caused by a variety of factors, such as deforestation, overgrazing, overfarming, and inadequate irrigation.
Deforestation removes valuable topsoil, while overgrazing removes precious organic matter from the soil, which can reduce its ability to retain moisture and nutrients. Overfarming and inadequate irrigation can cause soils to become nutrient deficient, leading to reduced crop yields, and can also lead to soil erosion and salinity.
Poor land management practices such as excessive tilling, compaction, and intensive pesticide and fertilizer use can also contribute to soil degradation. Soil degradation can reduce the soil’s ability to absorb water, leading to waterlogging and increased erosion.
Additionally, reduced nutrient content and increased soil erosion can lead to reduced plant growth and crop yields. Ultimately, soil degradation can have a tremendous negative impact on crop production, soil fertility, and the environment.
What farm practices impact soil do they impact soil in a positive or a negative way?
Farm practices can have both positive and negative impacts on soil. On the positive side, practices such as crop rotation, cover cropping and nutrient management can help build soil fertility and improve soil health.
Crop rotation involves growing different crop types in the same location year to year which helps to replenish nutrients and reduce the risk of pests and diseases accumulating in the soil. Cover cropping is planting crops that suppress weeds, help control erosion and improve soil structure, while nutrient management involves balancing the amount of fertilizer and other nutrients used on the land to increase crop yields and reduce environmental damage.
On the other hand, unsustainable farm practices can have a negative impact on soil such as soil compaction, erosion, nutrient depletion and pesticide and herbicide overuse. Soil compaction occurs when large machines drive over the soil, reducing its water and air storage capacity, limiting plant growth, and reducing water infiltration and drainage.
Erosion is the process of topsoil being removed from the land and is caused by wind, water and overgrazing. Nutrient depletion also occurs when crops and livestock take in more nutrients than the soil can replenish.
Pesticide and herbicide overuse can also damage soil by reducing biological activity and limiting the growth of beneficial microorganisms.
