Kajian ini bertujuan menentukan strategi pengurusan pembajaan yang tepat untuk tanaman mangga varieti MA 224 (Chokanan) di tanah bekas lombong, Tasik Utama Kampus Sultan Azlan Shah, Universiti Pendidikan Sultan Idris. Metodologi kajian melibatkan pendekatan kuantitatif berasaskan reka bentuk eksperimen terhadap 73 sampel pokok mangga dengan 2 strategi pembajaan yang dilaksanakan dalam tempoh 1 tahun (Mei 2024 hingga April 2025). Dapatan kajian tertumpu pada penilaian kesuburan tanah dan pola cuaca tempatan untuk membangunkan strategi pembajaan yang bersesuaian dan berasaskan bukti. Analisis tanah menunjukkan kawasan penanaman mangga adalah bersifat berasid sederhana (pH 5.3–5.4), kandungan bahan organik dan kalium yang sangat rendah, serta tekstur berpasir (60–65% pasir halus). Analisis cuaca bagi tempoh Mei 2024 hingga April 2025 merekodkan suhu purata 27.2–28.7°C dan taburan hujan bermusim, dengan bulan Disember 2024 dan Januari 2025 adalah paling lembap (>250 mm/bulan). Berdasarkan dapatan ini, 2 strategi pembajaan organik dicadangkan: (i) penggunaan Baja Organik Bioaktif Diptia dengan foliar Bio-Grow untuk meningkatkan aktiviti mikroorganisma dan ketersediaan fosforus; dan (ii) penggunaan Baja FN Rich Bio-Organik dengan foliar Bio-Grow untuk membekalkan kalium, kalsium dan bahan organik kepada tanah berpasir. Sudut pandang baharu kajian ini terletak pada pemilihan jenis bahan pembajaan organik dan bioaktif yang spesifik untuk mengatasi ciri ekstrem tanah bekas lombong. Integrasi data kawasan penanaman mangga yang spesifik dengan strategi pembajaan organik-bioaktif dapat menjadi model lestari untuk rehabilitasi tanah di ekosistem yang sudah rentan dengan tanaman bernilai ekonomi. Kesimpulannya, strategi pembajaan berasaskan analisis tanah dan cuaca yang spesifik kepada kawasan penanaman adalah penting untuk mengatasi kekurangan nutrisi tanah bermasalah dan mencapai pertumbuhan optimum tanaman mangga.
This study aims to determine an appropriate fertilization management strategy for MA 224 (Chokanan) mango trees in ex-mining soil at the Main Lake of Sultan Azlan Shah Campus, Sultan Idris Education University. The study methodology involves a quantitative approach based on experimental design on 73 mango tree samples with 2 fertilization strategies implemented over a period of 1 year (May 2024 to April 2025). The study findings focus on assessing soil fertility and local weather patterns to develop appropriate and evidence-based fertilization strategies. Soil analysis shows that the mango growing area is moderately acidic (pH 5.3–5.4), very low in organic matter and potassium, and sandy texture (60–65% fine sand). Weather analysis for the period May 2024 to April 2025 recorded an average temperature of 27.2–28.7°C and seasonal rainfall, with December 2024 and January 2025 being the wettest months (>250 mm/month). Based on these findings, two organic fertilization strategies are proposed: (i) the use of Diptia Bioactive Organic Fertilizer with Bio-Grow foliar to enhance microbial activity and phosphorus availability; and (ii) the use of FN Rich Bio-Organic Fertilizer with Bio-Grow foliar to supply potassium, calcium, and organic matter to sandy soil. The new perspective of this study lies in the selection of specific types of organic and bioactive fertilizers to overcome the extreme characteristics of former mine soils. The integration of data from specific mango planting areas with organic-bioactive fertilization strategies can be a sustainable model for soil rehabilitation in vulnerable ecosystems with economically valuable crops. In conclusion, fertilization based on site-specific soil and weather analysis is crucial for addressing nutrient deficiencies in problematic soil and achieving optimal growth of mango trees.
