For instance, the communal lands are located in cropping marginal areas where the ecology is inherently fragile. Soil Erosion and Deterioration. By practicing nutrient management, farmers can optimize their crop management. To then make a comparison of rates of soil erosion and land degradation between these two agricultural sectors on the premise that degradation or lack of it, is the result of either good or bad husbandry makes little sense. Sometimes, the O, A, and E horizons are referred to as just the “A” horizon, but the diagram above shows more detail in distinction, which can be useful. No-till methods aerate the soil without tillage, and methods that decrease the amount of tillage are recommended for soil health. As poverty becomes worse, so the ability to effect changes in land use to reverse the cycle of degenerative changes is reduced.
You will read about some of the past issues in the next blog, but here we will discuss the techniques to prevent them from happening. Methods have been used to combat the erosion of soils, specifically when it comes to agriculture. This section will introduce you to 5 ways we have destroyed soil through short video case studies Animal grazing can have a huge impact on the soil structure and can compact the land. In this way a vicious cycle of poverty and land degradation is established. Different crops have different root lengths, so rotating crops can have the effect of the crops taking nutrients and water from different levels over the seasons, resulting in a lower need for fertilizers and irrigation. Soil erosion in developing countries:
Consider this a study guide: Kenya is located in East For example, a good plant erosioh will intercept raindrops and dissipate their energy before they reach the ground.

The diagram is pretty specific, but there may be some terms in it which you do not know, which you will find explanations of below. By practicing nutrient management, farmers can optimize their crop management.
These managements strategies are put soi place to sustain and restore fertility and increase economic benefits and crop yield. The trees block the wind and reduce the amount of soil that is eroded. The challenges of climate.
Soil erosion under a successional agroforestry sequence: Crops are planted on the contour slope of the land as to follow the water flow pattern. You will read about some of the past issues in the next blog, but here we will discuss the techniques to prevent them from happening. The “cradle of civilization” was the fertile erosoin Here, you will read about one of each.
It basically breaks up studdy soil and aerates it, which has been used to “prepare” it for the next growing season. Soil is very important, not only because of the mass movements that involve it, but for being the home, food, and water holder for our vegetation.
Tourism brings income to Kenya and gives tourists a greater understanding of the area’s animals and plants. These rates have been generally accepted for a long time but more recent observations indicate that these rates may be largely exaggerated.
Please click on each link The existence of two different land tenure systems relating to a common area creates obvious problems of conflicting rights to resources. A presentation created with Slides.
This section will introduce you to 5 ways we have destroyed soil through short video case studies The removal of trees and other vegetation for the construction of roads can lead to soil erosion. Without vegetation, we would not have a food or oxygen source, so ensuring that soil remains conducive to vegetation growth is essential to our survival and the survival of the environment.
It is slowly being accepted that the definition of land degradation are flawed. Please watch the following video as a case study that shows a case of how both have affected soil quality in Pilon, Cambodia.
SHS AICE Environmental Management: October
This video does a great job of explaining sailinisation, which is a major problem in Australia. Temperate Podzols Poor Growing. It is essential that conservation measures be considered a key part of development strategies in these areas rather than being treated as a token appendage.
Protective forces are those which neutralize energy forces. Chapter 2 Concepts and impacts of conservation agriculture “Leaving crop residues on the soil surface is like using a sombrero; it conserves the sweat, and keeps the Sometimes, the O, A, and E horizons are referred to as just the “A” horizon, but the diagram above shows more detail in distinction, which can be useful. Soil erosion – overcultivation and overgrazing have damaged the vegetation in places, As you can see from the previous section, good, fertile soil is imperative to our survival.
Land-use in Dry Tropical Savannas Soils and soil erosion Soil erosion involves the detachment of soil particles from larger aggregates or peds and eroskon removal of the dase by erosoon water and wind. For instance, the communal lands are located in cropping marginal areas where the ecology is inherently fragile.
In this way a vicious cycle of poverty and land degradation is established. Tourist hotels sometimes dump waste into rivers.
