Soil Acidity Improvement for Pineapple Cultivation: Ananas Comosus L. Cultivar N36 on Bris Soil, Terengganu

A research study was conducted to investigate the improvement of soil acidity in Ananas comosus L. grown on bris soil, utilizing both pot trials and field experiments on Rhudua series soil. The experimental design employed was the Randomized Complete Block Design (RCBD), featuring six different treatments and four replications.

In this study, Ground Magnesium Limestone (GML) was strategically applied to mitigate the acidity levels present in the sandy soil. The GML was administered in four equal split doses, with six varying application rates: 0, 0.5, 2, 4, 8, and 10 Mgha-1.

The findings of the study revealed a significant positive impact on several key soil and plant parameters. Specifically, the application of GML notably increased the soil pH (H2O), as well as enhancing the concentrations of phosphorus (P), calcium (Ca), and magnesium (Mg) in the soil. Additionally, improvements were observed in the concentrations of calcium, magnesium, and copper (Cu) within the plants themselves as a result of the treated soil.

Moreover, the study recorded beneficial effects on various growth and fruit parameters, which included metrics related to the overall yield and quality of the fruits produced. These outcomes collectively underscore the effectiveness of GML in ameliorating soil acidity, ultimately contributing to better agricultural practices for cultivating Ananas comosus L. on bris soil. The results advocate for the application of GML as a remedial strategy to enhance soil health and plant productivity, thereby supporting sustainable agricultural development in acidic soil conditions.
