Senior Geography Project by Lachlan Sprott Sustainable Agriculture- Cudgen NSW Abstract The following report will examine sustainable agriculture in the area of Cudgen. I will be Focussing on the Cudgen soil conservation project, Compost trials, soil, the Cudgen erosion project, and organic farming. I have researched on the internet and also by talking to local farmers and land care groups. Introduction Agriculture is the main land use in Cudgen, it puts many impacts on the area, socially, economically, and environmentally, all these pressures are putting viability on agriculture in Cudgen. However there are ways we can solve these problems by following sustainable agriculture strategies.
Runoff into streams contaminates the water with animal waste which contains antibiotics and artificial growth hormones that are given to the animals to increase their size and to sustain their health. C. Pollution on soil is another problem that arises from factory farming. 1. Runoff contains high amounts of salts which degrade the soil and can contribute to
Based on your data, which type of soil do you think is best for agriculture? Explain your answer. Loam would be the best kind of soil to plant crops in because it is permeable but it takes low amounts of water to irrigate the soil. Farmers often have problems with soil erosion when they clear their fields after the growing season. Soil type is one factor that influences erosion.
| 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.
They are modified with herbicides and pesticides so the uncertainty of health consequences of humans consuming the food grown by these seeds exists. It could take
Also, as soft rock is being eroded at a faster rate than hard rock, steps in the riverbed are created, causing rapids. As the soft rock is being eroded, undercutting of the harder rock can occur until it collapses, causing a plunge pool and a waterfall. The land in the middle course is much flatter than the mountainous upper course because the middle course is closer to the sea level, away from mountains. Because the land is flatter, lateral erosion occurs, making the channel much wider. As a meander forms, an inside bend has less energy, so deposition occurs, causing a slip-off slope.
It will prevent cross contamination. 4. It is important to clear and dispose of food waste promptly and safely to prevent pest hazards. It will prevent multiplication of bacteria (Pathogens), Reduce risk of food decaying and becoming unfit to eat. 5.
It is also a weed suppresser to prevent other weeds from growing because it grows so fast and densely, it blocks out sunlight to other weeds that are trying to grow. This allows farmers to use hemp as a replacement for herbicides and reducing toxins into the ground and surrounding water sources. Hemp can be used to replace petroleum and plastic products and are still biodegradable so it reduces the amount dumped into landfills. Since hemp can be used to replace gasoline and petroleum essentially replacing oil this reduces the environmental risks and impacts of oil drilling. This is a major environmental impact made when off shore drilling accidents happen made seen to the public by the BP accident in April of 2010 where 200 million gallons of crude oil was “spewed” into the ocean.
To summarize what this article talked about it was a study done on the effects of soil degradation and the effects on the vegetation in areas around watering points and normal grazing lands. The study showed that in these ecosystems the overgrazing reduced the ecosystem diversity of plants in poor soils. It also talked about how overgrazing around certain areas can not only destroy the soil but it can also cause the destruction of certain types of species. Overgrazing differs in all areas of the world but it still has a common problem which is that when there is overgrazing no matter what type of environment you are in that environment will be
Pesticides are used in a certain amount to help farmers maintain unwanted pests from eating or destroying their crops, and helps preserve the produce life. Doing this helps the economy by maintaining the price of food. Pesticides have their pros and cons. To ensure that pesticides do not contribute more harmful waste than needed is to dispose of pesticides and their containers properly. Purchase pesticides; specific to the pests you are trying to control this way the pesticide does not harm other species in the process.
