Perbandingan Dua Metode Ekstraksi P Tersedia Pada Tanah Sawah Di Perlis Dan Kedah, Malaysia

---

ABSTRACT
Phosphorus (P) is an essential nutrient for plants, but its availability in soil is often limited due to its binding with soil minerals such as Fe and Al. The availability of P in paddy fields is strongly influenced by soil pH, organic matter, and redox conditions. Available P can be measured using various extraction methods, including Bray I and Bray II. This study compared the effectiveness of Bray I and Bray II extraction methods in measuring available P in 45 topsoil samples (0 – 10 cm) from paddy fields in Perlis and Kedah, Malaysia. Sampling was conducted using purposive sampling, and laboratory analyses measured soil pH and available P. Statistical analyses included Shapiro-Wilk test, Wilcoxon Signed-Rank Test, and kernel regression using R software version 4.4.2.Results showed high variability in P content with Bray I (CV = 85.50 %) and Bray II (CV = 65.86 %). The average available P differed significantly between Bray I (9.259 mg.kg⁻¹) and Bray II (29.490 mg.kg⁻¹). However, both methods showed weak correlations with pH (R² = 0.24 for Bray I and 0.30 for Bray II), indicating that neither method alone is sufficient. Further evaluation should include other influencing factors such as organic carbon and cation exchange capacity.
