1. Soil Conservation
Soil, which is one of the most important natural resources, is often less heeded. The importance of
soil conservation is relatively less talked about as compared to the conservation of water and other
natural resources. The almost–omnipresent soil is mostly taken for granted. Its omnipresence is
ironically the reason behind us, human beings, taking it for a ride. We rarely even think of it as a
natural resource that needs to be conserved, a part of the natural wealth that needs to be preserved.
The concept of the conservation of soil takes into account, the strategies for preventing the soil from
getting eroded and preventing it from losing its fertility due to an adverse alteration in its chemical
composition. Here are some ways to...show more content...
Salinity of soil is detrimental to the vegetative life in the soil. The death of vegetation is bound to
cause soil erosion. Hence, salinity management is one of the indirect ways to conserve soil.
Soil organisms: Organisms like earthworms and others benefiting the soil should be promoted.
Earthworms, through aeration of soil, enhance the availability of macronutrients in soil. They also
enhance the porosity of soil. The helpful organisms of soil promote its fertility and form an element
in the conservation of soil.
Indigenous Crops: Planting of native crops is known to be beneficial for soil conservation. If
non–native plants are grown, the fields should be bordered by indigenous crops to prevent soil
erosion and achieve soil

3. Water Conservation
WATER CONSERVATION
INTRODUCTION:
Water is essential for life on earth. Water is needed for growing food, keeping ourselves clean,
generating power, controlling fire and most importantly to stay alive! This list is simply non–ending.
This shows that water is an integral part of our daily life and we are heavily dependent on it.
Water conservation–
Refers to reducing the usage of water and recycling of waste water for different purposes such as
cleaning, manufacturing, and agricultural irrigation.
Water conservation can be defined as:
1. A reduction in water use accomplished by implementation of water conservation or water
efficiency measures; or, 2. Improved water management practices that reduce or enhance the...show

Using less water also puts less pressure on our sewage treatment facilities, and uses less energy for
water supply to the grid.
Why should you conserve water?
There are many good reasons to conserve water. Water conservation can help meet future needs.
Saving water will save you money. Water conservation helps preserve the environment. Saving water
will save energy.
Although water conservation helps, some people have misconceptions about what water
conservation can and can't do. If we all work together to conserve water, we can help assure a bright
and prosperous life for future generations. Become an advocate of conservation in your community.
Help promote conservation as a wise and important water management principle.
[pic]SAVE MONEY–
Conserving water saves you money! Not only will your water bill go down, but as you use less
water, your gas or energy bill will also decline. If your whole community conserves, you will also
pay less fees for water–related services. Water conserving communities will not need to pay as much
to develop new supplies and expand or upgrade water and wastewater infrastructure.
Wise usage of water helps us in saving money. We have to pay for the water we use. If we use less
water, we will have more money left to spend on other things.
Preserve the Environment–
Water is the life–blood of

4. Speech On Water Conservation
Dear Reader, Close your eyes and imagine this: it is summer and you are sitting on the edge of
the river bank. You are listening to the water as it swiftly rushes by you. You can see how the
Sun's light glistens off the transparent cyan water. A state of serenity overcomes you. There are
birds chirping all around and the most beautiful butterflies hovering around some nearby shrubs.
Now, open your eyes and go look at the closest river. Do you notice all the trash along the banks?
How about the water? Do you see the motor oil shining on it? Not so peaceful is it? Sadly, this is
a very common sight for most waterways in Kentucky. According to National Geographic,
developing countries dump 70 percent of their waste into the water. Yet water is very essential
for life. This is why we must have good water conservation practices. Without water conservation
the only way for us to have rivers like what I described will be when we imagine them. On
November 7, 2017, three classes of high school students at Red Bird Christian High School did a
water assessment of Red Bird River with the local Forestry Department. I had the opportunity to be
part of one of the classes. We studied macroinvertebrates and what they mean for the health of the
river. In the water assessment we took a D–net and in different spots of the river we went across
kicking up the dirt and rocks. After cleaning the net out into a bucket we cleared out all the leaves
and rocks. We looked at the rocks for any sign of

5. Soil Case Study
Sandy soils in the Southeast are characterized by low nutrient and water holding capacity which is
further reduced by intense rainfall patterns and has been exacerbated by long–term farming in the
region. These conditions lead to rapid nutrient loss in soils below the root zone. Nutrient run–off is a
well–established cause of non–point source pollution affecting bodies of water and negatively
impacting water quality.
Modern crop cultivars with higher yields also frequently demand increased use of fertilizers,
contributing further to nutrient run–off and pollution. In addition, soils in the Southeast range in
composition from deep sands to sandy loams, necessitating the development of a range of soil
management solutions tailored for the...show more content...
In addition, certain particularly effective nematicides have been unavailable or in short supply,
increasing the need for alternative, cost–effective solutions for controlling these pest.
This study proposes an examination of the soil amendments biochar, gypsum, and fly ash for
improving nutrient retention and water holding capacity in sandy Southeastern soils producing
cotton and testing biochar gypsum, and fly ash, with and without poultry litter and measuring the
soil nutrient profile, compaction, and pest populations before, during, and after each growing season
for two years in dryland farmed cotton.
The biochar, gypsum, and fly ash treatments will be applied with and without poultry litter to
compare the treatments as an alternative or adjunct to poultry litter fertilizer. The effect of both
treatments on thrip count and nematode populations will also be assessed.
The evaluation of biochar application to soil as a method for reducing N loss from fertilizers,
improving soil quality and fertility, and increasing yield and farm profitability have not been
thoroughly addressed (Hue, 2016).
2)Statement of Solution
The central idea of this study is to examine methods of making more efficient use of poultry litter as
a fertilizer in cotton production by reducing the amount of nutrient leaching and improving the water
holding capacity of the soil. Biochar, gypsum, and fly ash will be evaluated for enhancing soil

6. Water Conservation Of Water
The average adult human body can go approximately four days without water. This statement
alone tells us that water is very important to the human body. So what would we do without water
and why is this relevant? Without water we would die and this is a relevant matter because we
are overusing our water sources. If we continue to use too much water, Earth will no longer be
able to support us. According to Madison Powers, we are taking freshwater faster than it can
replenish itself (Par 2). This affects us all because everybody needs water to survive. How do we
solve this issue? Simple. Water conservation. There are some water conservation efforts in place at
this moment. For example in Cynthia Barnett's essay, " Water Works", it is brought up that green
roofs and cisterns can reduce run off by 50–85 percent as well as capture water for outdoor irrigation
(Barnett, 2). Everybody need to work together to cut down on our excessive use of water and help
conserve water in whatever way possible. Freshwater resources are being overused by us
humans. A rarely known fact is that only 2.5% of water on earth is freshwater (Powers, par 12).
Just to add to the problem, most of the freshwater resources we do have are not readily accessible.
When a freshwater source is found, it is quickly used up by our ever growing need for water. A
common estimate for the average amount of water used per day by each person is 80–100 gallons
(USGS, par 1). Take into consideration that we have about 320

7. Soil Conservation
INTRODUCTION
Soil is the precious gift of nature to the mankind. All the plant family, animal kingdom and human
society at large depend upon soil for their sustenance directly or indirectly. Ironically, soil is the most
neglected commodity on the earth. Shifting cultivation on the hill slopes, non–adoption of soil
conservation techniques, and over exploitation of land for crop production due to population stress,
leads to enormous soil erosion. It will take hundreds of years to form an inch of soil, but in no time
it gets washed away down the slope due to erosion.

A terrace reduces the length of the hill side slope, thereby reducing sheet and rill erosion and
prevents formation of gullies.
There are different types of terraces as follows:
вњ“ Bench terracing: It consists of transforming relatively steeps land into a series of level or
nearly level strips or steeps running across the slope. The soil materials that are excavated from the
upper part of the terrace is used in filling the lower part and a small bund is also raised along the
outer edge of the terrace to check the downward flow of rainwater and also soil erosion. вњ“
Channel terrace: It consists of making of wide but shallow channels across the slope of the land
either exactly on contour line or with a slight grade (0.1 to 0.2 per cent). In this process, the
excavated soil is placed along the lower edge of the channel in the form of low ridge. вњ“ Narrow
based terrace: It consists of making a number of narrow based ridges or bunds at a distance of 1m to
2m across the slope of the land at suitable intervals in high rainfall areas. вњ“ Broad based ridge
terrace: It consists of making wide but low bunds on the contour lines by excavating soils from
both sides of terrace. This is practiced in areas where the rainfall is relatively low. вњ“ Contour
trenching: It consist of making a series of deep pit (i.e. 2ft. wide and 1ft. deep) or trenches across
the slope at convenient distance. The soil excavated from the

8. Soil Salinity
Soil salinity Soil salinity is the salt content in the soil; the process of increasing the salt content is
known as salination. Salt is a natural element of soils and water. Salination can be caused by
natural processes such as mineral weathering or the gradual withdrawal of an ocean. It can also be
caused by artificial processes such as irrigation.

This is the case, for example, in large parts of Australia. Human practices can increase the salinity of
soils by the addition of salts in irrigation water. Proper irrigation management can prevent salt
accumulation by providing adequate drainage water to leach added salts from the soil. Disrupting
drainage patterns that provide leaching can also result in salt accumulations. An example of this
occurred in Egypt in 1970 when the Aswan High Dam was built. The change in the level of ground
water before the construction had enabled soil erosion, which led to high concentration of salts in
the water table. After the construction, the continuous high level of the water table led to the
salination of the arable land.
Dry land salinity
Salinity in drylands can occur when the water table is between two to three metres from the
surface of the soil. The salts from the groundwater are raised by capillary action to the surface of
the soil. This occurs when groundwater is saline (which is true in many areas), and is favored by
land use practices allowing more rainwater to enter the aquifer than it could accommodate. For
example, the clearing of trees for agriculture is a major reason for dryland salinity in some areas,
since deep rooting of trees has been replaced by shallow rooting of annual crops.
Consequences of salinity
The consequences of salinity are detrimental effects on plant growth and yield damage to
infrastructure (roads, bricks, corrosion

9. Water Conservation Essay
One of the items people, animals, and our environment cannot live without is water. Water is
extremely vital in the everyday life of everyone in the world from everyday life of drinking,
washing clothes, animals, grains, cleaning, and so many other uses that eliminating water would
eliminate our species as we all depend on the necessity of water. "The water footprint refers to the
volumes of water consumption and pollution that are 'behind' your daily consumption". (Network,
2010) If an average American uses approximately 80–100 gallons of water per day then an average
American needs to change their ways and contribute to a better water footprint. Water is critical for
ecological systems and the health of humans. Animals or plants...show more content...
Examples of products and water is that the "global average water footprint: 15500 liters of water
per kg of beef" and the "global average water footprint: 2400 liters of water for one hamburger!"
(Network, 2010) Understanding the amount of water our world uses is imperative as there are many
consequences to follow globally.
The global consequences of using so much water are that globally we are in a water crisis. The
demand for water is always a necessity and as population increases the need for water increases. The
lack of safe drinking water and sanitation varies from country to country. "More than one out of
six people lack access to safe drinking water, namely 1.1 billion people, and more than two out of
six people lack adequate sanitation, namely 2.6 billion people. 2900 children die every day from
water borne diseases". (Council, 2009) Not only is there a crisis with consumption of water for
people but also it is critical that humans reduce the amount of water they use for industrial and
agricultural development in order not to effect the aquatic ecosystems and their species. "Water
covers almost 70 percent of the surface of the globe and is the Earth's most abundant resource.
About 97 percent of the water is the oceans and is too salty for drinking, growing crops, and most
other human resources". (Frederick, 2004)
Since globally there is a water crisis, it is important to conserve as much water as possible every
day. Not only understanding how I
