Significance of the Study

o Field of agriculture (farmers, mussel cultivators)

o Potential use of mussel shells

o Stakeholders

Efficacy of Chitin to the pH level of an Untreated Soil

Statement of the Problemo significant difference to the pH level of the

soil treated with chitin

o noticeable effect of mixing the extracted chitin to the pH level of the soil

o direct relationship of chitin mixed to the soil and its pH level

Back

Hypothesis

There will be no difference in the pH level of the soil treated with chitin.

Back

Efficacy of Chitin to the pH level of an Untreated Soil

Scope and Limitationo process of obtaining chitin from mussel shells

o difference in the pH level of soil treated with chitin under investigation

o other effects of chitin to the soil would not be discussed

o neutralization of pH level of soil was not also included Back

Statistical Treatment1. One-way ANOVA

2. t-test pairwise

3. Pearson product moment correlation - two-tailed test was employed

Computation of Data

After all the data had been gathered, records were submitted to a professional statistician for accuracy and validity of the results to be discussed upon interpretation in the subsequent paragraphs.

Interpretationo ANOVA test shows that the p value (0.017309) is less than

0.05, which indicates that at least one of the setups is different from the rest.

o t-test between pairs, pair 1 (Setup A and B) p=0.86149; pair 2 (Setup A and C) p=0.028687; and pair 3 (Setup A and D) p=0.014407, it is established that pair 2 and pair 3 are significantly different from pair 1.

o Pearson Product Moment Correlation of Coefficient, the rxy for all days is almost 1. Thus, there is a direct relationship between the mass of chitin and the pH level of soil.
