Forest soils

Tropical Rain Forest Soils of La Selva Tropical rain forests across the globe are currently threatened by massive deforestation for logging, grazing, and cultivation (Otzen 1993). Such land-use practices alter temperature regimes (Fernandes and Sanford 1995) as well as ground, soil, and surface water, flora, fauna, and microorganisms (Otzen 1993). These changes may result in a loss of soil organic matter, a decrease in soil fertility (Garcia-Oliva et al. 1994, Tissen et al. 1994), severe soil erosion

Soil Degradation in Nigeria Introduction Nigeria is a country in West Africa, bordering Benin in the west, Chad and Cameroon in the east, and Niger in the north. Nigeria is in the tropical zone of Africa (between latitude 4 and 14 degrees N, and longitude 2 and 14 degrees E), with a vast area of savanna vegetation in the northern part. The climate is damp, very humid and highly influenced by the combined effects of the ocean, desert, humidity, temperature, and mainly the variation that exist in the

Green forest is easy on the eye, it breaks the harshness of roads and buildings and adds interest to farmland and mountain slopes. In its sanctuary birdsong and air currents play with your auditory senses and aroma 's of nectar, decayed logs and leaves fill the air. After a long absence from New Zealand, I decided to reacquaint myself with the types of forests found in the Land of the Long White cloud. In this article, I have based the forest communities on the categories from The New Zealand Plant

Forests are usually a beautiful place. They are filled with all different types of animals and noises. You can feel the sun on your skin as it shines in between the trees. The lush greenery around you makes you appreciate the nature. In Koshu, Japan, this is not the case. Aokigahara, is a forest placed below the Fuji Mountains. Unlike most forests, this one reeks of death and darkness. The fourteen squares miles are filled thick with trees. Tall trees that are so close together that the sun does

tragedy lies in the fact that most lands that have been deforested in recent decades are not suited for long-term farming or ranching and they quickly degrade once the forest has been cut and burnt. Unlike the fertile soils of temperate latitudes, most tropical forest soils cannot sustain annual cropping. The carrying capacity of the soil will not support intensive annual cropping without rapid, irreversible degradation. Similarly, intensive cattle grazing cannot be supported because

With over 130 million hectares of forest area, Indonesia has the third largest forest in the world. These forests are home to many diverse wildlife and unique creatures not found naturally anywhere else in the world. Before the 1950’s, these forests were dense and in a natural balance. With the introduction of greed in the form of humans and reckless machinery over 60 or so years, Indonesia has won the dubious honour in becoming the “World leader of deforestation”. This has led to an unnatural balance

science Semester 2: Taiga Region  Introduction            The boreal forest, also known as the Taiga region is the major life zone of vegetation that is composed of various trees, soils, flora, and fauna. The Taiga region reaches across the upper northern hemisphere. Thus following across Canada, Alaska, and northern New England: making this the largest land biome in the world. In this particular region, there are various types of soil, flora, and fauna that flourish. Also, as this is a giant turf of

Alicastrum Plan. The Brosimum Alicastrum is a large rainforest tree native to tropical regions and known as the Maya Nut tree. The tree grows to 130 feet, grows naturally in rainforest soils, can produce an average of 400 pounds of 100% organic nuts a year and have more vital nutrients than foods grown on farmed soils. Other than being one of the largest and fastest growing trees of the rainforest it produces a fruit high in protein, calcium, fiber, iron and vitamins A, E, C, and B. The nut can be

types of physical geography from Himalayan Mountains to Plains. Raiwala is the lowest point at 315 meters above sea level, and the highest points are within the Tiuni hills, rising to 3700 m above sea level. The Doon valley has the Terai and Bhabar forests within it as well as the Shiwalik hills and Lesser Himalayan Range containing hill stations such as Mussoorie and Chakrata. The Pteridophytes are known as botanical snakes of plant kingdom. They are the oldest land plants on earth, flourished so

in the Amazon, which makes it the most biodiverse tropical rainforest in the world. This great expanse of rainforest harbors about half of all species on Earth. As large areas of this tropical forest are cleared by deforestation, entire species are vanishing, many of them unknown. The dense tropical forests also hold a large amount of carbon that is being released into the atmosphere because of deforestation. Although deforestation in the tropics is rapid and widespread, some people are making an
