Some of the major effects of deforestation include biodiversity loss‚ local climate change and global warming. Farmers often have trouble raising crops‚ which typically results in more problems‚ such as an increase in food prices. Soil erosion and cultural displacement also can occur. Those who want to address the problem have a variety of options‚ however. Biodiversity Loss A loss of biodiversity often follows a reduction in the amount of forested land. Trees‚ shrubs and other plants provide shelter

melts‚ it can flood land and move the soil. Even something as small as an earthworm can cause erosion. Earthworms and other insects that burrow in the ground make tunnels in soil and reform it. Humans also greatly contribute to erosion. Because of humans‚ the Earth has gone through millions of years of farming‚ cutting down trees‚ and the development of architecture. Humans drastically changed the earth so much‚ that every year one million acres of top soil

edaphic factors were also done including soil sample collection and soil profiling. The samples were then brought to the laboratory for soil pH‚ moisture‚ organic and nutrient content analysis where cat ion-exchange capacity (CEC) of soil are described‚ and classified. Determination of soil inhabitants was done using Berlese-Tullgren apparatus. The obtained data concurred with the accepted general climate and soil condition of the selected premise. Soil exhibits a generally slightly basic nature

clearly depict that the amount of moisture in the soil on the south facing slope is much higher than that of the north facing slope. On average‚ the south facing slope contains 3.5 units of water while the north facing slope only contains 1.3 units of water in its soil. Therefore the amount of moisture in the soil on the south facing slope is signficantly more that of the north facing slope. As can be seen in Figure 4.1‚ all 10 sites have lower soil moisture contents on the north facing slope. This

They conserve soil by preventing rapid runoff of water after heavy rains‚ thereby reducing soil erosion and minimizing floods. Forests are also vital for increasing our ground water. Because of the thick humus layer‚ loose soil‚ and soil-retaining powers of the long roots of trees‚ forests are vitally important for preserving adequate water supplies. Forests contribute substantially

What is Salinity? Salinity – Salinity can be defined as the condition where the quantity of salt causes problems in the soil and impacts in the landscape. The term salinity can be classified in numerous diverse ways: irrigation salinity‚ dryland salinity‚ urban salinity‚ river salinity and industrial salinity. These contrasting types of salinity are arranged to how and where the salt has been located and what the effects are. An example of salinity is the amount of salt that is measured in a fish

The study presented in this thesis form a relationship between soil chemical properties throughout the years within Giant Miscanthus soil. Miscanthus is a perennial‚ rhizomatous‚ giant grass that was originated from East Asia and now distributed worldwide. This subtropical plant has C4 photosynthetic pathway and can be grown in warm seasonal weather. These perennial rhizomatous grasses are promising energy crops due to their high productivity‚ low nutrient requirements‚ ecosystem services and great

-How plants get liquid and minerals- Flowers absorb liquid through their roots‚ which are attached to xylem vessels. Xylem vessels are tubes that can expand through several feet of tissue and be .7mm in diameter. Their walls are thickened with cellulose deposits. Xylem bring water up to the leaves and petals of the plant. Even without contact with the roots‚ the xylem can still absorb water. Because of this‚ a cut flower usually doesn’t die for a couple days (as long as it is placed in water of

Temperature‚ moisture‚ soil type‚ microbial activity‚ oxygen concentration‚ sunlight‚ nitrification‚ and the amount of leaching all have an effect on the breakdown of pesticides in the soil (Extoxnet‚ 2000a). Rainfall patterns and the timing/intensity of irrigation in relation to high rainfall intensities will also influence herbicide movement in or from soil. Metolachlor is considered to be moderately persistent in different soil types (U.S. EPA‚ 1997)‚ and has an average field dissipation half-life
