Soil is the basis for the natural ecosystems and a living thing, it sustains life on Earth and works as a natural recycling facility with nutrients to the plants. However, many people do not know about the good benefits that soil gives to our lives and how humans hurt the conditions of soil with chemicals. Soil is often times mistreated due to the misconception of soil as dirt. Nevertheless, Professor Asmeret Berhe highlighted during the lecture, Soil, that soil is a place of full of life that supports living thing. The living organism depends on the conditions of soil because soil delivers nutrients to plants. For instance, improving the conditions of the soil increases the harvest of crops. Unhealthy soil will not be able to do its job as a natural recycling facility, and not be able to give a good amount of nutrients to plants to abundantly grow. Therefore, conditions of soil are very important in agriculture. Furthermore, having organic soils can conserve the amount of water used for irrigation. Soil is main supply of water to all land and plants because it holds the water for organisms. Organic soil can hold few amounts of water for a long time so it helps farmers to reduce the agricultural water consumption. Soil is very important to out lives than what we imagine and think. The global awareness of soil preservation is less significant to people than other conservation efforts like reducing the amount of plastic used, but soil preservation is very significant to our earth system. Therefore, it is very important for humans to help the Earth healthy sustain life by stop mistreating soil as dirt and treating it as a living thing that holds full of

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

In agriculture, soil can cause limitations to plant growth through (a) depth, stoniness, texture and structure which together can influence the amount of water which can be held in the profile and the ease with which roots can penetrate and (b) the availability of nutrients (Rowell, 1994). There are four main constituents of soil: mineral matter, organic matter, air and water (Fig. 1.1).

Election of 1828 is what started it all. Andrew Jackson and John Quincy Adams was running for President, and Andrew Jackson won by an overwhelming majority. Jackson established the Spoil System. The Spoil System awarded Jackson’s friends and supporters public offices. During the 1830’s, abolitionist began to rise, and people began to revolt, for example, William Garrison wrote the “Liberator”, and Nat Turner killed his master and 60 more people. Money was a huge issue because tariffs were raised, and Jackson destroyed the National Banks, which caused the Panic of 1837. The big issue during the 1850’s was the decision if slavery should expand into the new territory that America had gained from the Mexican War. The documents support the explanation

Soil, which is the layer of earth on the top where plants and vegetation grow, contains a pH balance, everything does. The pH, acidity, or alkalinity balance of each type of soil that is being observed can affect the plants, because it determines how many nutrients are being deposited to them. It

Loose soil from digging animals is easier for plants to grow in compared to the hard compacted soil found where there are no digging animals

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

Look around you; do you think that we need soil in our everyday lives? Sure we do. Natural flowing water is filtered through the soil thus making it drinkable. We breathe the air that is produced by plants that grow in soil. Our clothes wouldn’t be made if the cotton plant had no soil to grow in.

The soil has a thick litter layer, but thin humus layers due to fast decomposition. There is also a rapid leaking, which is the downward movement of the nutrients in solution in the soil. Soil is determined by the climate, vegetation, topographic position and soil age.

The predator populace in the earth populace is developing, while the predator populace in the grass is not advancing as quick. Everybody and each living thing are always advancing; in any case, since the knifes in the earth populace could outlast the forks, dissimilar to in the grass specialty, they are developing quicker. The spoons still ruled over all, surrendering the opposition over to the blades and forks. Table 2a obviously demonstrates that the knifes cooperated better, or were forceful in their approach of attempting to survive longer, and making more eras. Similar phenotypes were not supported in both the grass and soil populaces on the grounds that distinctive results came to be. On the off chance that the knifes just murdered off the forks in the grass segment, then the phenotypes would have been the same. The way that the knifes adjusted their nourishment on their mouths and afterward ate it was a key make, that drove them beat the forks. Since in the grass segment the forks likewise could defeat the do not have that their mouths stalled out within the individual clear out.

The microbes found in soil go hand in hand with the microbes found in our bodies, especially the gut microbiome. Soil is used to grow various plants and crops which we then ingest. As stated in Healthy Soil Microbes, Healthy People, we have completely destroyed soil microbes by overusing fertilizers and pesticides just like how we have destroyed our gut microbes by ingesting processed foods and large amounts of antibiotics. Soil microbes, including bacteria and fungi, form symbiotic relationships with plant roots to help provide the plant with many nutrients needed to survive. In order to restore and improve the soil once again, we need to reintroduce bacteria and fungi that are capable of repairing the damage. Through recent technological advances, the soil microbiome was genetically sequenced. This allows farmers and other scientists to understand which microorganisms are

“ 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

Micro-organisms like bacteria and fungi break the organic matter down. Animals like worms, mice, moles burrow in soil which help mix components and also provide ways for water and air to pass.

“On the global basis, the soil degradation is caused by over grazing (35%), agriculture activities (28%), deforestation (30%), over exploitation of land to produce fuel wood (4%), and industrialization (4%).” 100% of what causes soil degradation is caused by humans and animals. 35% of the blame goes to the animals for over grazing, but the other 65% of the blame goes to the humans for agriculture activities and chopping down trees. Another example is, David Pimentel also states, “The bottom line on soil production is that it takes (on average) about 100 years to generate a millimeter of soil. This is about a human lifetime.” Although it is stated that animals contribute to land degradation, it’s only a small portion (35%). The main reason for loss of arable land is human development. Forests are cut down for farming space, fuel wood, or space to build some kind of industry. When land is being used and used, and no one manages it, it can become deplete; which means, the land is dried out and unable to grow vegetation. Soil production takes a long time, on average, it takes 100 years. 100 years is too long to wait for new soil to plant food.

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
