Essays on Soils

Weathering and erosion are two basic events that take place on earth as part of the wear and tear of the natural resources like rocks, soils, and plants and trees that cover the earth. Closely observing weathering and erosion will help understand how the surface of the planet has been changing over the past several years and how it will change in the future as well. Weathering is the process through which rocks on the surface of the earth gradually break down into small pieces. On the other hand, erosion is the process through which the broken pieces and ...

INTRODUCTION

Economical and industrial development are two of the most important elements on the evolutional way for any country and nationality. However, it often happens so that people discover something new and hurl themselves into using it before making throughout estimations of potential risks and hazards. This is especially common if such newly discovered entity (an invention, or mineral, or a way to dig out minerals – this could be anything) is capable of making large sums of money: then there is no particular doubt of this entity becoming incredibly popular and exploited to the extent of being overused. To top ...

Introduction

One of the largest areas of the world where pastoral nomadism and irrigating agriculture had been predominant throughout the history is Central Asia. There existed a set of aspects of geography and ecology of Central Asia that influenced the emergence of pastoral nomadism and irrigation agriculture in that territory. In this paper we will attempt to explore some of the causes and effects of pastoral nomadism and irrigating agriculture in Central Asia, taking into consideration its ecological and historic settings.

Ecological reasons

First of all, let’s speak about some of ecological reasons of the appearance of pastoral nomadism and irrigating ...

Summary

In the world and over, there has been rapid industrialization coupled with quick growth and urbanization. These aspects have significantly posed different challenges not only related to the allocation of powers, as well as, resources but also those that have a close relationship with the natural environment. Besides, there has been a reduction in the gap existing between the urban and the rural setups, changing patterns of consumption and an increasingly growing population. A significant challenge that arises because of the problems above is that of waste management. It is on this basis that the proposal below will present ...

Introduction Bill and Kent Smith established Surefooting Foundations, Inc. (SFI) in 1978 as a residential foundation repair company. The need for foundation repair arises when the typical foundation concrete slab settles due to expanding or contracting soils. Repairs normally consist of digging under the existing foundation, jacking the foundation back into position with hydraulic jacks and then pouring new concrete under the foundation. SFI’s planned new product, a foundation stabilizing system, could dramatically increase revenues.

Organizational Vision, Mission and Objectives

SFI will help people to enjoy the ownership and comfort of their homes with the peace of mind that there ...

Introduction

Until recently, genetic foods have become popular for their ability to address many production and quality issues faced by natural/organic farming methods. Genetically modified crops are those whose genetic makeup has been improved to enhance the level of nutrients, resistance to diseases, increase yields, adaptability to climatic factors, and reduce the time of production (Ronald & Adamchak, 2008). It is different from the conventional breeding because genetic modification allows introduction of genes from any organism (animal and plants) in altering crops whereas breeding allows transfer of genes across related species only. On the other hand, organic farming is a natural ...

Ecological Imperialism in New England

Abstract: In 1492, Christopher Columbus landed in “the New World” and marked the beginnings of its extensive colonization. When European settlers arrived in the Americas, they brought with them their cultural values and began to adapt American land to their needs. Those days started ecological imperialism; “wilderness” of the Indian nature was disturbed. European settlers intervened the setting and brought significant changes in flora and fauna as well as the habitual way of living of Native Americans. This paper reveals the long-term consequences of English ecological imperialism in New England and ecological changes brought by European settlers. The main ...

Introduction

Much recent publicity surrounding climate change has focused mostly on global warming, but little direct correlation has been given in the media with regard to the impacts that environmental pollution has on climate change, and also on human health. Although studies of pollution and the environment have been carried out since the time of the Industrial Revolution, it only relatively recently that attempts to measure environmental on a global scale have been undertaken. Environmental pollution is a major cause of global concern, not only for the effects that it has on the physical environments, but also for its potential ...

Introduction

Sugarcane has been grown by human beings for many years because of its many uses. It is a perennial grass that grows well in frost-free tropical areas. The crop is mainly propagated vegetatively with 30-40 cm long fresh cuttings. The crop has a cycle of between 10-24 months modern agricultural practices have made it possible to reduce the growing period of the plant crop as well as for the ratoon crops. The current sugarcane crop is an inter-hybrid cane breed to provide high sugar content (Moore et al. 10). Originally, the plant was used for chewing, but currently, it ...

Introduction

In 2006, an apartment complex that included a playground was built on a piece of land that was the site of a metal processing plant that operated between 1930’s and 1950’s before going out of business. Due the above reason, the land had to be assessed for any carcinogenic heavy metals. There are so many potential heavy metals that could have hazardous effects on people’s health, but the assessment mainly focused on cadmium. This is because cadmium was the most common metal used in the plant while it was operational and the metal has both carcinogenic ...

Global warming and climate change are two different terms that have been used over the years to describe different phenomena. Global warming refers to a subsequent increase in the global average temperature (Black & Weisel 5). On the other hand, climate change refers to global climate changes due to increasing average global temperatures brought by changes in rain patterns, increased drought and heat waves. These future projections in the change of global rainfall patterns can be derived from the Intergovernmental Panel on Climate Change (IPCC) reports over the years. The argument that the use of term global warming has been ...

Introduction

The world we live in today has not always been what it is but has been built to what it is today. While little is known of the Western world, specifically the Americas before explorers such as Christopher Columbus discovered it, there exists rich literature of ancient civilizations that have shaped all spheres of modern life. The most recognized civilizations include the Egyptian civilization, the Roman Empire, and the Greek civilization. The fall of one civilization led to the rise of another civilization and so forth. The earliest recorded civilization, however, is the Egyptian civilization and scholars have credited ...

Question one

Ernest Rutherford made remarkable contributions towards radioactivity and the nature of the atom. He was the first man on earth to discover that atoms have a small nucleus that is charged and its surrounded by space which is circled by very tiny electrons. This was what became to be known as the planetary model or Rutherford model of the atom. Rutherford collaborated with Fredrick Soddy on research on transmutation of elements. The two researched in X-ray effects based on conductivity of gasses ("Ernest Rutherford: Father of nuclear science," 2014). This is where they came up with the ...

Conservation of Earthen Architecture in Saudi Arabia

Research Methodology Finding comprehensive sources was a challenge during this study. This difficulty was due to the inadequate number of research studies that have been carried out on the ideal conservation and restoration methods suitable for historical earth buildings in Saudi Arabia. The study has employed two procedures. In 2013, the investigator travelled to Saudi Arabia and carried out an exhaustive research on the remaining earthen architecture. He looked at the general status of the buildings (dilapidation, corrosion, and decay), the construction materials and techniques as well as the architectural styles and decorations. In addition, laboratory tests were done ...

Introduction

Permeability also known as hydraulic conductivity is the ability of the soil to allow the water to pass through it with ease. The characteristic property of soil is useful in calculation of the seepage in the dams and under sheet pile walls. It also helps in determining the rate of seepage through the facilities for storing waste water such as landfills and fish ponds. Moreover, the rate of settlement of clayey soils can also be established. The determination of hydraulic conductivity of soils can be performed using several methods. The method of constant head is used to determine the ...

My two-year crop rotation plan will include seed corn and soybeans. Soybeans will be planted in the first year on a virgin land followed by seed corn in the second year. The inclusion of a leguminous crop, like soybeans, in crop rotation, improves the soil fertility as well as the structure (Mohler and Johnson, 2009). Legumes releases nitrogen to the soil, which will reduce the amount of nitrogen fertilizer needed for the sweet corn in the following year (Griffin, Liebman, and Jemison, 2000). These crops will be planted in North Carolina.

Soybeans

The soybean cultivar to be planted is Envy, ...

According to EPA (2016), environmental management involves the development of systems aimed at reducing environmental impacts of various activities. In the Brundtland commission report (WCED), sustainable development has been described as development aimed at meeting the current needs of the present generation. However, as the current generation focuses on meeting their own needs, their activities should not compromise the capability of future generations to also meet their own needs. Available evidence suggests that the future generation would have challenges meeting their own needs if the current generation fails to adopt sustainable practices. The sustainable development incorporates the triple line: ...

Question 1

Cultural leveling describes how people from different cultures approach each other and try to reach common grounds regarding communication and interaction. This process is evident in Lee’s ethnographic fieldwork. Coming from white society, the researcher exhibited arrogance and considered himself superior, both intellectually and culturally, to the !Kung bushmen. He did this by extending to or cutting off the supply of tobacco from the Bushmen since he was the only source of the commodity in 1000 square miles (Lee). Besides, he neither shared his food with the Bushmen nor participated in their food-gathering activities. For this reason, the ...
