Determination, Organic Matter, Total Nitrogen And Elemental Content Of Cow Dung

Chapter One


1.1 Background of Study

Wastes are everywhere. These substances are unpleasant to see and also bring harmful effects to our health and environment. Example of this waste is the manure of the animals like the cow.

Cow dung causes a problem when these are just leave behind the sidewalks streets or in an open field. If these substances decomposed in places like these , though the manure are gone but the micro organisms they carried still remain. And we should not treat these organisms as small issues because these can destroy our health especially when these are stick to our food, mixed with the water we drink, or touched by our bare feet and hands.

The only way to stop these troubles is to decompose these wastes in a right process and could use it as fertilizer to plants. This research wants to know if this manure decomposed, if it’s could be a better fertilizer and brings a better effect on the growth of the plant. (Carlo, 2007)

1.2 Aim / Objectives

The aim of this research is to determine the elemental content of Cow Dung, its total nitrogen and organic matter. The objective includes comparing the values with other animal waste and recommending its use as manure.

1.3 Scope and Limitations of the Study

This study is limited only to the dung of cows. Urines and other parts of cow are not included in this research study. Other parameters to be considered are total nitrogen, organic matter and the macro minerals. Due to time and finance constraint, few parameters were used for the analysis.

1.4 Significance of the Study

This work will be significant to farmers because it will help those plants growers to know cow manure could be a better substitute on their usually used fertilizers.

1.5 Analysis of Data

This raw data obtained in this work shall be analyzed using simple percentages, mean and standard deviation.

1.6 Definition of Related Terms


This is a large female animal kept on farms to produce milk or beef.

Cow Dung:

Cow dung, also known as cow pats, cow pies or cow manure, is the waste product of bovine animal species.


These are chemical substances added to the soil to bring about an increase in the yield of crops and consequently the farmer income.


Manure is organic matter, mostly derived from animal feces except in the case of green manure, which can be used as organic fertilizer in agriculture.


These are naturally occurring inorganic substances with a definite and predictable chemical composition and physical properties


This is a substance that cannot be broken down into simpler components by any non – nuclear chemical reaction.

Animal Waste:

Animal waste comes from livestock, poultry, and dairy production.

5.0 Summary, Conclusion and Recommendation

5.1 Summary

The use of cow dung in various processes varies from culture to culture. Whereas in India it is used traditionally as main source of fuel, in many villages in Nigeria cowdung is of great advantage to small and medium scale farmers because it serves as an organic manure to plants.

This study has been able to bring the usefulness of cowdung into light in the time with inorganic manures. Analysis of the total nitrogen content, organic matter and elemental composition has acknowledged the fact that cowdung may be an important agent in soil fertility improvement. The appreciable mineral content suggests that it can play vital and crucial role in improving soil structure and plant development.

5.2 Conclusion

Conclusively, this research has shown that cowdung offers a rich and cheap source of soil organic matter and minerals which can go a long way to replace fertilizer. Thus its usage as soil manure should be encouraged among small and medium scale farmers.

5.3 Recommendation

Based on the results of this study, it can be recommended that cow dung should be used as a form of organic manure because of its rich elemental and nitrogen contents.

5.4 Suggestion for Further Studies

  1. Other animal dropping like pigs, goats should be researched into with a view to comparing their organic contents.
  2. Microbiological analysis of cowdung should be studied in order to guide the users on potential hazards.
