Summary
Soil variability can be defined as the observed variability on a considerable distance between units that are distinctly different like land facets and parent materials. Considering the previously done research, there has been very little attention that has been given towards…

In order to gain knowledge on soil microvariability, this paper explores the variation degree in some soil and the maize yield. In this paper, we hypothesize that there would be more yield in an arable land than in nonarable land. The null hypothesis of the study will be that there would be a higher maize yield in arable land than in non arable land.
The impact of mineral nitrogen fertilizer was observed on the yield of maize crop. This yield was measured in milligrams of dry mass harvested in 100 acres for a period of a year. The process was done for both arable and non arable land in the sites close to Germany, and Malle. The maize yield was observed from 1990 to 1988. The climate variation on both types of land were also recorded.
From the results, it is evidenced that in a percentage nitrogen concentration of 0.12, there was more maize yield in nonarable land than in arable land. This shows that there were differences in the management practices involved in the arable, and in nonarable land (Moss, 2007). It can also be agued out that the amelioration, and fertilizer addition in the different soils were responsible for the different yield of maize (Murphy, 2006). In this respect, the study rejects the null hypothesis thus adopting the alternative hypothesis of the experiment. In this respect, the alternative hypothesis includes; a lower yield in an arable land than in nonarable ...Download file to see next pagesRead More

Since 19th century scientists were aware of some unique identity of an individual which distinguish from others, like finger prints. In 1970, DNA was established as key element in human life and which makes individual as unique creature. Variability in DNA sequences among individual to individual have attracted forensic experts to develop technique based on DNA to identify individual or criminal similar to finger prints.
