Forests A forest is an area filled with trees which provides homes for many different living things. The forests found in Trinidad and Tobago are called Tropical Seasonal Forests because they are found near the Earth’s equator and have both wet and dry seasons. __________________________________________________________________________________________________________________ A forest is made up of different layers. The Emergent Layer is very sunny because it is at the very top and only the

One of the major environmental issues with the Himalayas is deforestation. Most of the trees in the Sub-Himalayas have been cut for land and lumber. Because of the deforestation‚ other issues like soil erosion and landslides have arisen. Overpopulation is another problem in the Himalayas. "Nearly 40 million

The people were evacuated‚ but the area was completely polluted. The stock started eating plants that grow in polluted soils and the meet that was taken from the cow and eaten by humans had an accumulation of toxins. To prevent this the state start planting green plants in the polluted soil to remove the toxins

an excellent rotation crop of cotton‚ maize‚ groundnut‚ wheat‚ and sorghum. It reduces nematode populations that attack cotton and groundnut. It is also an excellent soil builder- it improves the soil texture and moisture retention and lessens soil erosion: the composted sesame leaves left on the soil binds the ground; retains soil moisture better for planting the next crop; increases the yield of the following crop. Sesame is resistant to drought‚ tolerant to insect pests and diseases‚ a low cost

Even though a lot of the valley is rural there are a lot of urban cities here in the valley. I want to tell you about the five different biotic communities in the valley‚ how they’re made up‚the quality of our air and what we as people can to due to save water. The valley grasslands main abiotic factor come from the climate and the parental material and soil. The climate can

trip Noel introduced us to the no dig system‚ which is environment friendly. Essentially‚ a no-dig garden comprises layers of varying organic matter piled up. This allows the entire area to be accessed without walking on the garden‚ thus preventing soil compaction‚ which is detrimental to worm activity and healthy plant growth. The layers of a no-dig garden are similar to those of an efficient‚ fast-working compost heap. Using such a varied range of organic materials creates high nutrient levels and

the system and conserve resources. One way farmers are going to do this is by stopping the plowing of the fields. That way‚ they will be preventing the soil from sucking in all of the water. Another way farmers are going to conserve is by growing high residue crops. In other words‚ if they leave dried out corn or other crops‚ it will cover the soil and create residue. Lastly‚ farmers can capture more rainfall by trying not to pump from the aquifer unless needed. In addition‚ if the attempt fails

Deltamethrin is the most commonly used pyrethroid in agricultural practices commonly used in different geographical parts of the world. It is detected in many environmental areas such as soil and water‚ posing a toxic effect on humans and other organisms. In the current study‚ a fungal S1 strain was isolated and enriched from soil sample originally obtained from Vellore agricultural site. The 18s rRNA of the

Red soils develop in a warm‚ temperate‚ wet climate under deciduous forests and have thin organic and mineral layers overlying a yellowish-brown leached layer resting on red layer made of iron oxide(ferric oxide). Red soils generally form from iron-rich sediments. They are usually poor growing soils‚ low in nutrients and humus and difficult to cultivate. These soils are developed on old crystalline rocks under moderate to heavy rainfall conditions. They are deficient in phosphoric acid‚ organic matter
