Abstract
This lab was performed to research the quality of pea plants germination and growth in two different soils. To obtain the results, pea plant seeds were placed in three different soil types: sand, hummus, and a mixture of sand and humus. The control of the experiment was the mixture of the two main soils (hummus and sand) being used. The seeds were planted and watered each week. The results came to be unexpected because only one pot had germination and growth of a pea plant in it. This pot was one of the four that contained hummus. The conclusions came to be inclusive since the results were not anywhere near what was expected by the group. Therefore, possible errors were sought out to see the reasons for the results. Introduction

In this experiment, the seeds of pea plant were tested in different soils to see which of the selected soil would have a higher success rate of germination and growth. Soil is made up of bedrock that has been weathered or came from erosion and it includes air with dead and living organic material. Soil helps support a plant by keeping it secure from the wind, providing it with feeding nutrients, and storing water for later use (Treseder, K, & Vitousek, 946). The soils that were used were hummus, sand, and a mixture of the two. Hummus is said to be one of the best contributor to plant growth because it is made up of fifty percent of organic molecules (Humus). The organic molecules are seized by the roots of the plants to feed the plant in order to grow. With a soil that is half nutrients for a plant, there is no doubt that a pea plant can survive in a hummus based environment. Basically, hummus can be categorized as a fertilizer because of the organic material that it contains to promote the survival of a plant. On the other hand, sand is totally the opposite. Sand is made up of mostly small solid rocks with little to no organic material, which means that there are no nutrients for plant survival (Zhang 86). It’s more than...
