Duckweed Eutrophication

1719 Words7 Pages

Introduction

Our aim of this experiment is to determine how eutrophication affects the growth of duckweed by adding different concentrations of fertilizers to the water with different types and forms of fertilizer keeping it in set conditions for a period of two months to observe how eutrophication affects the growth of duckweed. Thus our hypothesis for this aim is that it is expected that eutrophication would affect the growth of duckweed when different concentrations of fertilizers are added to the water. The reason for studying this aim is that we wish to see how eutrophication affects plant growth in the water even if fertilizers are added to the water.

Khan and Abide Ali Ansari as its explains how eutrophication can impact plant growth as well as “The Green Kingdom; Encyclopaedia by Child craft page 57relates to our experiment as this page explains exactly how duckweed growths and the certain conditions it grows in.[ Khan. A; Ansari. A.A.; Eutrophication: An Ecological Vision, The Botanical Review, December 2005 , Volume 71, Issue 4][1] [The Green Kingdom ; Encyclopaedia by Child craft Page 57][2] Further more articles such as “How To Grow Duckweed” by Jenny Harrington and “The Charms of Growing Duckweed by John W. Cross were also relevant to our experiment as they both state what fertilizers can be used when growing duckweed and in what different conditions duckweed can be grown in. [Harrington, J. (2013). How To Grow Duckweed. Available: www.ehow.com/garden. Last accessed 26th May 2015][4] [Cross, J.W. (2014). The Charms Of Growing Duckweed.

Last accessed 26th May 2015][5] Moreover the literature used in this experiment was all useful as it explained what factors needed to be taken into account to grow duckweed successfully and this lead to proving our hypothesis that eutrophication affects the growth

According to Harrison Eutrophication is the excessive production of algae and higher plants through the enrichment of waters by nitrogen and phosphorus. Phosphorus in the form of phosphate is the limiting nutrient as the amount of biologically available phosphorus is small in relation to the amount needed for algal growth. Harrison states that sources of nutrients can be discrete, (sewage), or diffuse, (farmland fertilizers).

Radish Plant Experiment

Abstract: The purpose of this experiment was to determine whether the amount of topsoil would influence the growth of radish plants. It was hypothesized that if the amount of topsoil increased by 50% would increase because topsoil contains the essential nutrients which are required for proper plant growth. The principle findings indicated that a medium amount of topsoil is ideal for plant growth as the radish plant potted in 50 ml of topsoil experienced the most growth in comparison to the radish plants potted either in 25 ml or 200 ml of topsoil. Introduction: A healthy layer of topsoil comprises of a mixture of clay, sand, silt, and humus that supply the plants with vital nutrients, such as nitrogen, phosphorus, potassium and other necessary

This week reading was enjoyable because I love poetry that uses nature as inspiration. In the reading “Urban Tumbleweed” by Harryette Mullen it was interesting because she made connections to her daily walks to inspiration for poetry, for example, she stated “desire to strengthen a sensible habit by linking it to pleasurable activity. I wanted to incorporate into my life a daily practice of walking and writing poetry”. Mullen’s text is also very relatable to me because I know that when I’m writing, I need a change of scenery, being inside and siting in a chair makes me feel less relax and more anxious.
