Soil Erosion Human Actions
1,131 words
Soil erosion is a gradual process that occurs when
the actions of water, wind, and other factors eat
away and wear down the land, causing the soil to
deteriorate or disappear completely. Soil
deterioration and low quality of water due to
erosion and run off has often become a severe
problem around the world. Many times the problems
become so severe that the land can no longer be
cultivated and is abandoned. The key to minimizing
soil erosion and saving the farm lands is the
farmer himself. Ultim...

estuaries, and irrigation and hydropower systems.
In the USA, soil has recently been eroded at about
17 times the rate at which it forms: about 90 % of
US cropland is currently losing soil above the
sustainable rate. Soil erosion rates in Asia,
Africa and South America are estimated to be about
twice as high as in the USA. FAO estimates that
140 million ha of high quality soil, mostly in
Africa and Asia...

Carbon Dioxide Plant Growth

Soil, superficial covering of most of the earths
land area; an aggregation of unconsolidated
mineral and organic particles produced by the
combined action of wind, water, and organic decay.
Soils vary widely from place to place. The
chemical composition and physical structure of the
soil at any given location are determined by the
kind of geologic material from which it
originates, by the vegetation cover, by the length
of time that the soil has been weathered, by the
topography, and by artifici...

H 2 > Introduction to Septic Systems The
septic system is a grouping of components working
together to decompose household waste water. The
septic tank holds the waste and breaks the organic
compounds into a solid, liquid or gas. The solid
waste (called sludge) settles to the bottom of the
tank and must periodically be removed. The liquid
waste is flushed to the distribution box and is
then allowed to drain into the ground through a
series of perforated pipes (often called lines or
a leac...

... serves to trap the bacteria before they enter
the soil. Factors affecting the translocation of
bacteria include bacterial numbers in the
effluent, soil texture, soil wetness, loading
rate, temperature, and bacterial type. Unsaturated
flow beneath a drain field is important in
ensuring slow travel, long residence time for
bacteria, good aeration, increased opportunity for
contact between effluent and soil particles,
adsorption of bacteria to soil particles, and
eventual die-off of bacteria. W...

Western United States Sulfur Dioxide And Nitrogen
1,519 words
Acid rain is polluted rain. The pollutants go up
to the atmosphere and when it rains it brings the
pollution down with it. Sulfur dioxide and
nitrogen oxide are the gases that form the acid
rain. When these gases mix with moisture it can
make rain, snow, hail, or even fog. The scientific
term for acid rain is acid deposition which means
when the acid is taken from the air and is
deposited on the earth. Major industries, coal
burning factories, power plants and automobile
engines are the main sou...

Tucker distinguished three principle types of
termites in Florida, they are: (they nest in the
soil), dogwood termites (they infest dry wood) and
damp wood (they infest damp wood). And
subterranean termites were defined by the
researchers as the most destructive and frequently
encountered kind of termite found throughout the
state. The chapters that are ...

How pH of Soil affects a Plants Growth For the
experimental aspect of the research report, four
sets of two plants are to be studied. They must
either be checked according to size for the same
height, or started from seed to ensure equality.
Two identical sets of roses are to be cultivated,
as well as two sets of corn plants. The flora must
all be given the same amount of water and sunlight
each day. The only variable to be changed is pH.
One of each set will be planted in the acidic
soil, and o...

Acquiring Good Seeds Quality seed strains are
often difficult to obtain. This is especially true
for people who hang in a predominantly straight
crowd and know few people who partake in the fine
erb. The rule of thumb is if the weed gets you
pretty high then the seed is usually good to grow.
Seeds coming from green bud are often better to
grow because the strain is frequently acclimated
to the growing season of northern latitudes.
Jamaican and Colombian varieties can not be easily
