Problem Statement: How do different amounts of soil affect the pH of water? Is the relationship the same for different types of soils? Background: PH is a measurement of how many ions of hydrogen are found in a solution. The pH scale measures how alkaline or acidic an object is. The scale has numbers ranging from zero (which are considered the most acidic) to fourteen (the most alkaline, otherwise known as the most basic). Pure water has a pH of seven, however most water, either from the tap or…

primary and secondary mineral. Calcium is found in lime stone but is also added as lime and in fertilizers. However, Calcium is not added as the soil is insufficient in Calcium, but to increase the pH. Calcium is a macro-nutrient which is essential in plant growth, the functioning of root tips, and is a main constituent in the cell wall. The amount of Calcium in soil will depend on the parent material and extent of weathering. Immobility of Calcium will be seen at the growing tips of the plant.…

contamination in soils is generally the result of anthropogenic sources. These sources have been mostly phased out in North America during the past several decades. However, Pb contamination is a persistent problem especially…

Question/Purpose: Do different diets affect earthworms and the soil they enrich? Hypothesis: The diet that is best for earthworms is one made up of soil and grass, because earthworms are more likely to have grass in their environment outside the classroom. Introduction: Earthworms are defined dictionary.com is “any one of numerous annelid worms that burrow in soil and feed on soil nutrients and decaying organic matter.” However, what if the “soil nutrients” were changed into three different…

of North Dakota conducted an experiment to find out the effects of sodium chloride on the plants that are not naturally grown in salty soils. Wisconsin Fast Plants, which are naturally grown in low to no sodium chloride concentrated soils, were planted and grown in several different salt concentrations to discover whether the plants grew better or worse in given soil concentrations. After multiple measurements, the results came back that the plants do not do well in concentrations greater than…

featured is the Soil Kitchen Project which involves a “temporary, windmill-powered architectural intervention and multi-use space where citizens enjoy free soup in exchange for soil samples from their neighborhood". The exchange of the soil for the soup allows for an exchange of dialogue and action to establish the value of natural resources through a trade economy and tools to respond to possible contaminants in the soil. The Soil Kitchen takes direct action in the testing of the areas soil to…

temperatures prevail. Insufficient soil moisture results in a longer and thinner root, while very wet conditions have the opposite effect and also give rise to a lighter colour. Carrots develop a rougher appearance when the temperatures are fairly high in summer and where there are varying soil-moisture conditions. Forked and cracked roots are more common in summer and the central core tends to be…

our soil capability to continue supporting crops and livestock. The overgrazing has impacted the semi-arid Midwestern states and ranchers know about the need to rotate livestock from site to site to conserve grass cover and soil fertility. Today, more ranchers are searching for ways to raise livestock more sustainably while taking care of the land. Iowa and Illinois use the soil conservation practices of no-till and cover crops…

distribution of a particular soil sample by carrying out sieve analysis and hydrometer analysis tests. For the sieve analysis test, a graph for percent finer versus the grain size was plotted from the data collected. The graph was used to determine whether the soil sample was fine-grained or course-grained. Calculations for uniformity and gradation were then done to determine whether the soil was well graded, poorly graded or gap graded. For the hydrometer analysis test, the soil sample was…

with Gatorade grew only a fifth of what the smallest plant watered with water. However, it is unknown if the Gatorade directly affected the plant or had more affect on the soil. The soil was obviously affected by Gatorade, as the soil became tough and more rock like. The Gatorade may have made the soil less fertile than the soil of the control. Our hypothesis was proven as correct, as the Gatorade plants didn’t grow as well as the control plants. Despite that, it was more of a difference in…
