The sweet potato industry, although a high value industry, is becoming increasingly competitive. This underlines the importance of efficiency in minimising the loss of valuable soil. Large amounts of rainfall can result in the loss of soil on cultivated farmland. The loss of soil does not just affect the farmers it also affects the community The aim of the project was to increase awareness of soil health and to develop the best soil management practices for the Cudgen plateau. Figure [ 2 ] Water Way On the Cudgen Plateau, three adjoining landholders implemented soil conservation measures and strategies.
Mud is a form of soil that is saturated with water. However just because mud also has moisture, bacteria, and organic matter, mud doesn’t have oxygen. By not having oxygen the apple will saturate itself with water and will not be able to breakdown the material by bacteria. Sand is a very dry environment and the apple will decompose over a time period but will not be as rapid. Sand is mostly made of material grains.
The water is not easily absorbed into the clay because it is harder for the water to enter the pores. Soil type and texture are very important to farmers. Too little water in the soil may cause plants to wilt and die. Too much water in the soil can disrupt a plant's ability to take in oxygen. Based on your data, which type of soil do you think is best for agriculture?
e. both are fiercely competitive and cannot coexist. 1 18. The pioneering work of Nalini Nadkarni in rain forest ecology revealed that: a. epiphyte mats in some tropical forests contain nutrient quantities equal to the nutrient content of the canopy foliage. b. the epiphyte mass in temperate rain forests may be four times the mass of leaves on their host tree. c. in both temperate and tropical rain forests, trees obtain nutrients by extending roots into epiphyte mats.
| Soil Erosion | Tree major practices | Rosa Flores 2/18/2013 | Three major practices that expose soil to erosion and how they can be corrected. Soil erosion is the loss of soil caused by particles being carried away by wind or water. Erosion moves the smaller particles first and hence degrade the soil to a coarser, sandier, stonier texture. The major causes of soil erosion are over-cultivation, overgrazing, and deforestation. They are creating problems to create a more sustainable society but it can be corrected.
‘Soft engineering is a better river flood management scheme than hard engineering,’ Discuss this view Soft engineering works with natural processes, it works with the environment and is often sustainable whereas hard engineering works against natural processes – controlling the environment. An example of soft engineering is naturalisation which is an attempt to alter natural geometry of a watercourse. For example planting trees – trees are planted near a river this means there Is greater interception of rainwater and a lower river discharge. An example of where naturalisation has occurred in the River Rhine where they are dredging clay out of flood plains creating a natural flood plain. An example of hard engineering is river straightening, this works by creating a smoother channel for faster flow to get water out of an area as quickly as possible.
Introduction Tropical rainforest, temperate coniferous and deciduous woodland forests are the three main categories of forest type. Tropical rainforests are considered a much richer species that the other two, and temperate vegetation is one that grows fastest. The rainforest ecosystem is very weak and easily unbalanced, making this type of forest more “permanently destroyed” than the other two. The importance of tropical rainforests lies within the fact that they are the earth’s richest source of life as they play a vital part in the earth’s natural cycles of soil, water and air through the process of photosynthesis. In this case study we will be looking closely at the tropical rainforest in the Amazonia region of South America.
These are: • The Bottom Layer • The Middle Layer • The Top Layer The Bottom Layer - This consists of ferns, small plants and saprophytes. The Middle Layer - This layer has trees, ferns and eprophytes. The Top Layer- This layer contains tall trees that have buttress roots. • The leaves of the tall trees will form a continuous canopy which will shut out most of the light at the ground level resulting in little undergrowth. • The majority of the trees in the rainforest are broad leaf and green which helps in getting rid of excess water through transpiration and leafs will protect themselves through a drip tip.
Due to the lack of filtration, families had been drinking water from the rivers that had later tested positive for cholera. (Cherry, 2010). The Foundation is currently working to restore the filtration plants. Following their goals of a sustainable community, Hope for Haiti also has a reforestation initiative. The goal is to replant the mountainsides, and to plant crops such as grapefruits, mangoes, cashews and coffee to name a few.
With the destruction of the rain forest, climate started changing. With less rain forest, there is less rain resulting in less water for the crops thus causing a drought. How does this cause a drought? The destruction of groundcover can lead to a change in local temperature. “Without trees, erosion would have worsened, carrying away fertile topsoil.
