Ammonia: The Passed Gas, Part III

Overview

Objectives/Goals My project was to determine if manure from a horse (through a change in the animal's diet), can be used as effectively as steer manure when utilized as plant fertilizer. I believe that the altered horse manure will be as effective as steer manure when used as plant fertilizer. Methods/Materials After collecting manure samples from both horse and steer, mix each with three different types of soil into six pots as a 4:1 ratio (soil to manure). Mix each pot throughly and plant bean seeds. Over a three day period test the soil mixture for nitrogen, pH, and appropriate fertilizer levels in each sample. After the three day period expires, continue to log and measure the number of bean plants in each pot, as well as the plant height, and over all grow rate. Results After testing and growth measurement, the mixture of potting soil and horse manure produced the greatest number of bean plants as well as the tallest and largest bean production of any of the six samples. Conclusions/Discussion My conclusion is that it is possible, with alteration, that horse manure can be used as effectively as steer manure as a form of fertilizer.
