The Effects Of Soil And On The Environment

Poor soil management can lead to biological, chemical, and physical degradation, which can in turn negatively alter the activity of

Soil Erosion - When the top layer of soil is worn down due to too much water, ice, or wind.

Soil organisms provide ecosystem services such as maintaining soil fertility and preventing soil erosion. Water, wind, ice, and other agents cause soil erosion, the wearing away or removal of soil from the land. Soil erosion reduces fertility because essential minerals and organic matter are removed. Erosion causes sediments and pesticide and fertilizer residues to pollute nearby waterways ( Wiley, 2009).

The pH of soil is important for the absorption of nutrients into the plant. Of the 17 needed plant nutrients 14 of them are acquired through the soil. Acidity is needed to break down and dissolve these nutrients. The nutrients are able to dissolve into the soil faster when the acid is acting as a solute. Another way the pH affects the soil is by influencing microorganisms. The bacteria is crucial in the growth and development of the plant, the bacteria’s role is to break down and decompose organic matter in the soil. If the pH of the soil is too high the acid will slow down and eventually stop the microorganisms. Most plants ideal pH is between 6-7, slightly acidic. Many plants are outliers and thrive in pH such as carrots and corn, which can withstand pH as low as 5.5. If the pH of the soil is too high for the desired crop farmers can add material such as limestone, and wood ashes to raise the pH to the desired level. The pH of the soil can also be changed naturally through the leaching of calcium, magnesium and sodium by rainwater. Carbon dioxide from rotting organic matter can also increase the pH of the soil. Acids can also be created organically in the form of sulfuric and nitric

Soil turnover - as soil is moved around by digging animals, organic matter is mixed through which distributes nutrients throughout the soil

They play a key role in regenerating and displacing soil. Earthworm activities changes both physical and chemical characteristic of soil. They help convert organic matter to humus. Additionally, they ingest other particles (sand grains) and when it is digested and excreted, it is accessible for plants to take advantage of its minerals and nutrients. Physically, the earthworm creates tunnels for air and water to navigate the soil. () They play an essential role in fighting erosion and are vital to plant growth. Healthy soil is depended on a thriving worm population. The ability to break down organic matter and excrete nutrients makes the earthworm valuable to restoration projects. Some people have employed earthworms to prepare soil for the return of native flora. Individuals that utilized this idea have seen better results in the return of their soil ecosystem than previously used methods. The number of

There are many ways to conserve soil. Windbreaks, cover crops and crop rotation are some methods to conserve soil. Windbreaks are tree lines that are planted around crop fields to provide shelter from the wind which in turn protects the topsoil from erosion. Cover crop is a crop that is planted just to occupy the land but they are not always harvested because the land is occupied by crop year round this reduces soil erosion. Crop rotation is a set of crops planted in order and repeated yearly. Examples of crop rotation are corn could be planted one year, wheat the following year and hay the third year. Crop rotation has various benefits such as the soil health is increased, the water absorption into the soil is increased and most importantly soil erosion is

Franklin D Roosevelt once said, “the history of every Nation is eventually written in the way in which it cares for its soil.” The United States began seeing sustainable management practices in farms, and healthier soil through this act. In 1982 through 2007, the United States soil erosion had declined by 43%” (Montanarella, 2015). Every year the United States loses about $400 billion dollars due to crop soil that is eroded. Soil is a limited resource and the largest resource for growing food, accommodating diverse ecosystems, and providing food resources. Therefore laws, acts, and provisions are necessary to protect this natural resource.

Today, in the United States, farmers and ranchers produce a wide variety of commodities for food, fuel, and fiber in response to markets. These farmers understand and recognize the significance of managing their soil as well as their plant productivity. America’s farmers are true professionals because crop production is a very complex business.

“ Without soil, land plants as we know them could not grow, and without plants no animals could survive”(53). This quote shows the great importance of one of our most important resources soil. “Perhaps the most important organisms in the soil, are the smallest-the invisible hosts of bacteria and threadlike fungi”(54). And, this quote shows how important the small organisms are. These include bacteria, fungi, and insects, which play such are large roll in life and are commonly being overlooked. One way they are being overlooked is by having chemicals sprayed on them and no one wonders what will happen. Well, if you are spraying chemicals to kill insects, it is most definite that the insects, such as earthworms, are going to be killed as well. These organisms are what make our soil so fertile, and without them we won’t be able to grow as much food. That being said, if we continue to plague the organisms of the soil with chemicals eventually, we will have less soil. We will no longer be able to grow as much crop due to this and we will not sustain the same lifestyle that we had

This topic is important because in the A-horizon of the soil which contains humus which comes from dead organisms, decaying plants and animal remains. Earthworms inhabit the A-horizon and they can alter the soil structure, the flow of water, nutrients available in the soil and the plant growth, while providing many beneficial functions. The earthworms help increase microbial activity by feeding on microorganisms and then creating casing from their waste which are the cycling of nutrients from organic material into nutrients forms that the plants can use. Earthworms excrete a caste and they can move soil down each horizon so the nutrients from the casts can reach deep down into the soil. The earthworm casts contain essential nutrients and minerals like phosphorus, nitrogen, sulfur, and potassium that are needed to help the plant grow.

Households can recycle and reduce their amount of waste by taking certain biodegradable materials and start a compost bin. It is here that the common wastes such as food scraps, coffee grounds or anything that has a high organic matter can be put together and let nature take its course. “Using composts in agriculture to minimize organic wastes and to reduce the addition of fertilizers and fungicides in crop production is highly effective”. (Stan, Virsta, Dusa, Glavan, 2009 pg 1) So the compost that is produced can be used to help fertilize the ground in which crops even flowers are grown cutting down on pesticides and fertilizers. The organic component, in materials, can be used in compost recycling to help to promote a healthy soil. By having a healthier soil this provides a healthier plant. This

Erosion removes the surface soils, containing most of the organic matter, plant nutrients, and fine soil particles, which help to retain water and nutrients in the root zone where they are available to plants. Thus it affects the productivity of plants. The remaining, the subsoil, tends to be less fertile, less absorbent and less able to retain pesticides, fertilizers, and other plant nutrients. There are over 17,000 soil types recognized worldwide. They vary widely in structure, erodibility, fertility, and ability to produce crops. A generalized soil profile for a humid, temperate climate is showed. When the natural vegetation is cleared for agriculture, soils become exposed to erosion and loss of soil fertility. The removal of the above-ground natural

“If you truly get in touch with a piece of carrot, you get in touch with the soil, the rain, the sunshine. You get in touch with Mother Earth and eating in such a way, you feel in touch with true life, your roots, and that is meditation. If you chew every morsel of our food in that way you become grateful and when you are grateful, you are happy.” Said Thich Nhat Hanh. Soil erosion is the process by which the surface of the earth is worn away by the action of water, wind or by living organisms. Geologist said that about 70% of soil erosion is caused by human activities like agriculture, surface mining, excessive construction and forestry. The soil conservation is happening because of geographic and economic reasons. Agriculture also takes place for being a cause of erosion.

Land Degradation is a global issue caused by multiple threats of the decrease of topsoil and land productivity from erosion processes and overuse. It is the process of human-beings affecting the atmosphere. As a result of land degradation, many negative impacts cause major threats to the environment such as food production, livelihood and also provision of other ecosystems.
