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...

It is often the most limiting nutrient for cereal grain production and represents one of the highest input costs ($847/ton anhydrous ammonia and $592/ton Urea) in agricultural systems (Nehring, 2013). Nitrogen use efficiency is very low (30-50%) in cereal crops, indicating that much of the nitrogen is lost from gaseous plant emission, soil de-nitrification, surface runoff, volatilization, and leaching (Frink et al., 1999; Mullen et al., 2003; Fageria and Baligar, 2005). Loss of nitrogen causes unnecessary cost of nitrogen application to the farmers as well as negative environmental impacts especially ground water pollution. Nitrogen application in wheat increases grain yield (Caviglia and Sadras, 2001). Altman et al., (1983) found 3% and 8% increased in yield due to the application of nitrogen over the control in two environments at Pendleton, Oregon. The timing of nitrogen application is also one of the critical factors affecting yield. Appropriate management i.e. rate and timing of application of nitrogen is essential to obtain higher yield in wheat production (Blankenau et al., 2002; Cui et al., 2010; Abedi et al., 2011). For the better yield of wheat, it is essential to get enough amount of nitrogen, when crop response is expected to be high (Mullen et al., 2003). Each variety plays a significant role in the nitrogen uptake (Dhugga and Waines, 1989; Ortiz-Monasterio R. et al., 1997). Hergert and Shaver (2009) recommended the optimum nitrogen rate of 112.1 kg ha-1 (100 lbs. acre-1) for dryland and 168.1 kg ha-1 (150 lbs. acre-1) in irrigated areas for winter wheat cultivars of…

Different farming techniques cause negative effects on organic matter in the soil. Because chemical fertilizers are so cheap and effective, they have been overused and have damaged soils. The effects of the chemical fertilizers have killed much of the organic matter in the soil. This loss in organic matter lowers the soils aeration and water holding abilities. Soil aeration is important because it allows water to get to the roots. Soil aeration also helps to get nutrients to the roots of a plant. The microorganisms that are destroyed can help to degrade the amount of pollution in the soil. Tests have been taken on the transition from conventional farming systems to organic systems which showed that the transition had an increase of microorganisms in the soil (De Araújo, Ferreia, and de Melo 2423).…

The failure of one crop could be compensated by the good growth of the other which output can cover the cost of production. The differences in the depth of rooting, lateral root spread and root densities are some of the factors that affect competition between the component crops in an intercropping system for nutrients (Abdulraheem and Charles, 2013; Carruthers et al 2000). The cereal component, maize in this experiment usually is taller, has a faster growing or move extensive root system particularly a large mass of fine root and is competitive for soil nitrogen closer row spacing increases yield and the smallest row spacing results in the highest yield for maize and cowpea (Abdulraheem, et. al. 2012). Different crops have their own maturity dates and having one crop matures before its companion crop. This reduces the competition between the two crops. Selecting crops or varieties with different maturity date can also assist staged harvesting and separation…
