The Effects Of Soil Management On Environmental Quality And Production Of Agriculture

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

Extracted soil samples indicate simultaneous reduction of rainfall and occasional erosion. Both soil and sediment features show establishment of marked

Vast numbers and kinds of organisms, mainly microorganisms, inhabit soil and depend on it for shelter, food, and water. Plants anchor themselves in soil, and from it they receive essential minerals and water. Terrestrial plants could not survive without soil, and because we depend on plants for our food, humans could not exist without soil either (Wiley, 2013).

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 acidity/alkalinity is essential for farmers determining the profitability of planting certain types of crop in certain areas. Some plants grow well in slightly acidic soils while others prefer an alkaline environment.

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.

When assembling all roles of soil, one is able to see that soil plays a vital part of the natural environment. It is just as important as plants, and animals. It influences the distribution of plant species and provides a habitat for a wide range of organisms.

With soil being washed away nearly 10 – 40 times faster than it is being replenished1, every single idea to avert this this crisis needs to be considered. No till farming, a method by which farmers implement a way of growing crops with minimal disturbance to the soil and the soil’s abiotic and biotic components, is a very important idea that is being employed worldwide with notable results. With food prices rising and people turning to their own backyards to grow food, the potential advantages of small scale no till can play a major role in the health and regeneration of our

Soil is the most important element for agricultural ecosystems. Healthy soil comes with beneficial microbes and insects. Unfortunately, these are often killed off by the abuse of pesticides. Healthy soil can produce strong crops that are less vulnerable to pests. Damaged soils often need strong fertilizers application to produce a high amount of crops. Soil quality can be amplified in many ways, including leaving crop remainders in the field after harvest and adding composted plant material (Union of Concerned Scientists) Compared to industrial agriculture, companies continue to damage and consume natural soil. While intensive plowing and monocrop (does not rotate) agriculture systems have caused nutrient exhaustion and soil erosion. Excessive application of fertilizers and pesticides has contaminated soils and polluted waterways (Grace Communications Foundations)

“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.

According to the European Union’s Joint Research Center, soil contains nearly one third of all living organisms, but only about one percent have been identified. Another study in 2003 featured in the journal Ecosystems estimated that 5% of the United State’s soil biodiversity was “in danger of substantial loss, or complete extinction, due to agriculture and urbanization.” (Robbins) The damage comes from multiple sources. Paving or building over soil effectively blocks out the air, water, and light needed to have a functioning soil biome meaning that roads, cities, sidewalks, houses, and businesses have destroyed the soil beneath it. Agricultural practices remove organic material, decreasing food, and then allows fallowed land to become dry and exposed to the elements. Household, industrial, and agricultural toxins can also sterilize soil if not disposed of

Therefore, a regional management strategy should be explored, and the development of local soil criteria are suggested by scholars and policy-makers (Song et al., 2016; Xia, 2013; Xia and Luo, 2007).

A. There a many different test that are chemical and physical that we could use for our soil sample. One physical test that can be performed is a particle size distribution of a soil sample. For this test, you get your sample of soil and place it in a jar. You then add water, a drop of soap, and shake the jar. After a length of time the contents of soil will develop into layers. You would then see the makeup of your soil with sand being at the bottom, silt in the middle, and clay at the top. You can then find the distribution of the soil and determine the soil texture. This soil test could help a cooperative extension service to determine if they need to add more contents like sand, silt, or clay so it will increase the growth of plants on that particular area where the soil is growing. A chemical test that can be preformed is a PH test to get the acidity of the soil. You test this by placing PH paper in soil concentration and the color change will indicate the PH of the soil. The a high PH shows the level of the base while the low PH will show how acidic the soil is. This is important to a recommendation because the PH can affect nutrients, minerals and growth.

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
