Asian Clam (Curbicula fluminea) Shells as an Alternative Soil Acidity Regulator

Abstract

INTRODUCTION

This study entitled Asian Clam (Corbicula fluminea) Shells as an Alternative Acidity Regulator seek to test the efficiency of the pulverized Asian clams as an acidity regulator at varying amounts in a fixed soil from Cavinti, Laguna. Researchers were measuring the pH level thoroughly in their research. The researchers conducted this study mainly because of the problem with soil acidity.

METHODS

The researchers gathered 15 kilograms of Cavinti soil which is Acidic with a pH measure of 4.2 given by the Municipal Agriculturist Office. The researchers also gathered 12 kilograms of Tulya shells in Sto. Angel, Norte, Sta. Cruz, Laguna. The shells were pulverized. After the collection, they proceed with the preparation of the samples in which they prepare 3 samples and 1 control. Treatments were all in a controlled quantity of soil which is 1 kilogram per sample. After a month, it showed various results.

RESULTS

By getting the absolute value of the difference between the pH of the soil from the first day and after one month, the results were used for ANOVA. It shows the computed value which is 322.6077 while the f-Critical is 4.066181. Then, t-test was used to determine which is more efficient. The computed value of t was compared to the t-critical.

DISCUSSIONS

The ANOVA shows that the soil regulator is significant to use as an alternative soil regulator. On the other hand, the results from the t-test show that treatment C became the most efficient. Based on the processes used, it indicates that as the number of shells placed in a soil, the more the soil is able to regulate.
