Factors that Affect Soil Nutrients
Nutrient availability can be influenced by several factors and these include:
1. Soil Ph: The relative concentration of the hydrogen irons and or hydroxyl irons may either increase or decrease nutrient availability.
2. The Presence of Other Nutrients: The essence of the various mineral salts will either increase or decrease the other mineral salts in the soil.
3. Leaching: This encourages the draining of mineral salts from the topsoil to subsoil thereby depriving plants of such nutrients.
4. Crop Removal: This may be in form of clean clearing, deforestation or cutting down of harvested crops which lead to loss of nutrients in the soil.
5. Oxidation and Reduction: This is a form of chemical reaction in which the electron(s) is or are either lost or gained thereby changing the state of the mineral salts. In such a changed state, the mineral salts may be washed away.
6. Burning: This kills soil organisms, destroys the texture and structure of the soil and finally reduces plant nutrients.
7. Erosion: This helps in washing away of soil nutrients from one place to another, and may occur under the influence of heavy rain or wind storm.

Erosion
Soil is a natural body consisting of layers of primarily mineral constituents, which differ from the parent materials in their texture, structure, consistence, color, chemical, biological and other physical characteristics. Plants and crops need soil to live and grow on; they are important for the environment, animals, and human beings as they release oxygen into the environment during photosynthesis, and are sources of food for omnivores, and herbivores. Therefore, soil erosion, which is the deterioration of soil by the physical movement of soil particles from a given site, can damage the environment; destroy the human beings and animals’ food sources. In this research paper, I will discuss about the causes, effects and the solutions for the soil erosion.
There are many different

    5. Salt kills the plants because the cells of plants contain water and many other dissolved substances. Since the water has a lower concentration, water molecules try to move the inside and outside the cell wall to equalize the concentration of dissolved substances in the cell, which is called osmosis. Water molecules will be sucked out of the cell by a high concentration of salt, and resultingly it causes the plants to dehydrate due to an osmosis.…

    When moss grows on rocks it releases chemicals that slowly dissolve the rocks. Plants contribute to rock erosion when the roots grow through cracks in the rocks as the roots search for water. Soil can also become victim to plants slowly eroding it; when the plants release chemicals it breaks down the soil. Managing erosion can be an arduous process; educating others can help in the efforts of controlling erosion.…

    The vital minerals that are needed by soil are washed away because there are no trees to absorb them. Also, this takes away food sources and shelter for various organisms. This disrupts the delicate balance of ecosystems. Selective cutting, is when a small group of mature tress are individually cut or in small clusters. This means that the rest of the forest is left undisturbed. However, this method is expensive and does not generate timber needed quickly enough.…

    Small variations in salinity can make a monumental difference on the water cycle and the ocean circulation. Trouble can also arise when saltwater gets transferred onto the earth. That can damage the soil and wreck habitats! There are two types of salinity, primary and secondary salinity. Primary salinity is when water or soil naturally has a high amount of salt in it, like in a salt lake. Secondary salinity is caused by humans. It can be caused by clearing too much land, which makes the groundwater rise to the surface and the salts inside dissolve into the soil.Secondary salinity has two main forms of which it happens. The first is dry land salinity; when more water enters the groundwater than is taken out, so it can enter vegetation on land and become absorbed by the soil. There is also Irrigation salinity; (Irrigation is the act of flowing water over crops to nourish them), salts can collect in the topsoil under the irrigation. Too much irrigation or poor water are the main causes of…

    Soil is the layer of broken rock particles and decaying organic matter on the surface of earth, which is essential for the growth of plants. It comprises of all the necessary nutrients that aid the growth and development of plants and trees. There are different types of soils, each one of them varying in its nature and texture. While some soils are deep rooted, the others are present on the margin. They also differentiate in their color, as some may be red while others are black. There are various types of soil and each carries with itself different nutrients, which assists in the growth of various plants and crops. Read on to get more information on various kinds of soils.…
