Title: Using Scientific Method

Instructions: You will need to write a 1-page lab report using the scientific method to answer the following questions:
Define a hypothesis that is suggested by the data collected in the lab.
Complete a lab report using the scientific method.

When your lab report is complete, post it in Submitted Assignment files.

Part 1: Using the lab animation, fill in the following data tables to help you generate your hypothesis, outcomes, and analysis:

Purpose
The purpose of this lab is to analyze the use of mineral nitrogen on the yield of maize crop during a time-frame of 1 year in arable and non-arable lands.
Introduction
Growing maize in arable and non-arable soil. At times when the soil is non-arable; which means a few different things and conditions are present. Example of non-arable soil would be elevated levels of pollution, marsh lands, or an abundance of salts and sands (MUSE 2013). Besides adding the mineral nitrogen fertilizer to non-arable soil there are other ways to help make it arable. Some of these are to dig and install irrigation canals and wells, if the land is too hot adding trees for shade is often done (NON-ARABLE SOIL). In this lab we will record the difference when mineral nitrogen is used on non-arable and arable soil types to grow maize.
Predicted Outcome/Hypothesis:
To add the content of nitrogen rich fertilizer will increase the yield of maize in arable land and non-arable land.
Methods
The results were collected using the M.U.S.E link and were thoroughly analyzed for proper judgment and verification.
The land site chosen for this experiment was both arable and non-arable near the city of Melle, Germany.
Results/Outcome: Amount of Mineral Nitrogen Fertilization (kg per 100 acres) Yield of Maize (mg of dry mass per 100 acres per year) in Arable Soil
Amount of Mineral Nitrogen Fertilization (kg per 100 acres) Yield of Maize (mg of dry mass per 100 acres per year) in Non-arable Sandy Loam Soil

Analysis:
I was correct in my hypothesis to believe the maize would grow at a much faster rate in the non-arable soil. Throughout the experiment it grew at a faster rate every time the mineral nitrogen was added. As the end of the fertilization process came to a close at 180 KG per 100 acres, both the arable and non-arable based maize plant were at the same yield of 20.1 mg of dry mass. I believe this happened due to the arable soil be farmed in the past and the nutrients hidden within the non-arable soil were brought to the surface a...
