The Relationship Between Soil Properties and Soil Erodibility Essay

The Relationship Between Soil Properties and Soil Erodibility - Essay Example It has the largest water holding capacity which helps to absorb water during the rain and helps in reducing soil erosion (Genna Dunjo Denti,2004, p.125). Soil aggregates are group of soil particles that are bonded together strongly to each other than to the adjacent particles with the help of organic matter. The space between the aggregates provides pore space for retention and exchange of air and water. Desirable aggregates are stable against rainfall. When less organic matter is used to bind these aggregates, due to rainfall these aggregates break down and leads to soil crust formation, this crust in turn increases the infiltration and air permeability, this in turn disturbs the surface soil and sub-soil structure. Thus inclusion of organic matter aids in the formation of stable aggregates and strengthen them. They also increase the porosity of the soil for air and water movement. Thus aggregating helps in reducing soil erosion. As the strength aggregates depends on the organic matter, since the organic matter acts as a binder to the aggregates. Hence weakening of this bond due to frequent tillage ultimately breaks down the aggregate structure of surface soil (Rachman, Anderson, Gantzer and Thompson, 2004, p. 31). Splash erosion is the removal of sand by impact of raindrops on the soil surface, this is also known as soil splash detachment (Jean Poesen, Gerard Govers(2001), p.1,2). If the soil is loose and friable, it has the maximum water holding capacity. This water holding capacity of soil stops soil erosion due soil splash detachment. If the soil is too loose it is very much prone to both the wind and water erosion. Wind erosion includes moving of the soil particles due to wind velocity and when these moved soil particles collide with the other particles and break them .If this continues then the soil is eroded by the wind. Wind also makes some soil particles to remain suspend in air and stay there till the wind continues leading to erosion. Water erosion mainly removes the soil particles by force of water and loss of various soil particles into ground water through infiltration. This leads to rapid dry out of soil due to lack of moisture holding capacity and leachate of minerals and other desirable elements. If the soil is dense, more overland flow may increase the erosion rate (Dr.Cooper, 2005, chapter-2). Soil Color Soil color is one of the physical indicators of soil condition. Soil color is most easily determined characteristic and helps in determining the other characteristics of soil like water-able depth and chemical constituents. Surface soil Surface-soil is the top most layer of the soil and is in interference with the atmosphere. This soil comprises of the organic matter such as manure and dead plants

Human resource management strategy - Case Study Example The author has rightly presented that in the past two decades, there has been a trend towards employee relations where businesses are turning towards maintaining good relationships with their employees. The modern business environment demands that an organisation have a good relationship with the employees in order to be competitive in the market. In the earlier days, employees were treated like they did not matter to the firm and the employer had all the power. The modern business environment has given power to the employee, leaving the employer to have to reconsider the way he or she treats the employees. Organisations which are good at treating their employee in a positive way are able to gain a competitive edge in the market and those which are not able to develop a good relationship with the employees are left behind and eventually pushed out of the market. Firms have to know how to engage the employees. Engaged employees are those employees who are willing to go the extra mile with regard to the services they offer the firm. Employee engagement leads to a psychological contract that the employee feels obliged to fulfil. This psychological contract is what makes employees be creative and innovative and help the firm to be competitive in the market. As a result, many firms have tried to develop strategies to increase and maintain employee engagement as well as manage the psychological contract.... This psychological contract is what makes employees to be creative and innovative and help the firm to be competitive in the market (Banfield & Kay, 2012). As a result, many firms have tried to develop strategies to increase and maintain employee engagement as well as manage the psychological contract. Advice to McBride Offering Equity in the Firm The many solutions that have been offered are all useful in managing such a situation. However, there are other ideas for managing the situation that may be more applicable to the situation. As discussed above, the main issue is managing employees’ engagement and psychological contract. One of the main ways of doing this is offering employees equity in the firm. By offering the employees equity in the firm, McBride will not need to increase their salary, yet the employees will have been motivated because they will know that any expansion in the business will lead to them benefiting in the long run. This will also increase the employe es’ engagement since they will feel that they are working for themselves and not for the firm. Offering autonomy Giving the employees autonomy in what they do will also be an easy way to increase their morale. Although this may not work so well on itself, when applied together with giving the employees equity in the firm, it can result in a highly motivated and engaged workforce. This will be more applicable with the older employee who have been in the firm and are looking for personal growth than salary increment. Question three Training The first area would be on training. As Sharma (2009) says, training is a very good investment for any business and also helps in motivating the employees. In other
