The paper " Laboratory Analysis: Muttama Catchment" is a perfect example of a case study on agriculture. Different soil and water properties were analyzed. By examining the effect of land management on the soil as well as the effect these activities have on the potential of eutrophication, conclusions were drawn about the state of the soil and the physiological effects of salt on plants and animal life. Based on all data we have tested and the nature of the land of Muttama catchment, we hypothesize that increased flooding will lead to increased eutrophication which will have an effect of increasing the plant growth.
The assessment of both water and soil eutrophication has been concluded by taking into account simple individual parameters like total nitrogen, total phosphorus, etc. Different soil samples from different sites will be analyzed for different qualities so as to determine how the varying salt concentrations, so too will the water. For all variables, increased salinity was found to have a negative effect on plant growth which served to negate the potential of eutrophication. This suggests that either the contents of the soil or the properties of the water negatively affect growth in plant cells. Laboratory Report: Muttama Catchment Introduction The objective of this lab report is to discuss the problems of salinity and the potential for eutrophication in the Muttama catchment.
The specific categories selected to test the water samples were total nitrogen, total phosphorus, dissolved oxygen, dissolved organic carbon, alkalinity, and PH. The soil samples were also tested and the categories included: total soil carbon and nitrogen, total soil phosphorus, PH and EC, soil available P and N, e-CEC and ESP, and soil texture.
The importance of analyzing the relationship between several of the categories cannot be understated as they hold the key into answering conclusively, whether the potential of the eutrophication is undermined or otherwise. While eutrophication results in the nutrient enrichment of waterways, poor land management can result in catastrophic effects for the practice of agriculture where control of catchment processes needs to be stabilized, as the deterioration of water quality leads to poor water use. The major influence on the water eutrophication is a combined complex function involving these very same factors.
Eutrophication can be accelerated by human activities and hence further waste (Gerritse et al. 1990; Skogen et al. 2004). The use of chemical fertilizers and detergents leads to increased nitrates which will result in accelerated eutrophication. The rivers and the ponds are filled with not only these nitrates but also the phosphates that are washed up to these bodies of water in sufficient quantity. This will have the effect of making water bodies shallow as the plants will increase and start choking the water bodies and the increased nutrients as the effect of animals in these bodies of water suffocating as the oxygen is limited and most of the fish and mollusks will eventually die. Other human activities that have the effect of accelerating the eutrophication process include the clearing of forests, human settlement, the building of cities and industries.
These activities have led to increased nutrients in the catchment and the eutrophication process has had both economic and social problems (Huisman & Hulot 2005). High percentages of catchment clearing have been responsible for the catchment areas losing nutrients to waterways.
