PODSOLIC SOIL IS SOIL FORMED FROM PARENT MATERIAL CONTAINING MINERALS SUCH AS QUARTZ, FELDSPAR, AND MICA. PODSOLIC SOILS HAVE VARIOUS COMMON PROBLEMS, INCLUDING LIMITED AVAILABILITY OF PHOSPHORUS NUTRIENTS, A TENDENCY TOWARDS ACIDIC pH, AND HIGH EXCHANGEABLE Al CONTENT. THIS RESEARCH WAS CONDUCTED ON PODSOLIC SOIL IN RUBBER PLANTATION LAND IN CEMPAKA DISTRICTS, SOUTH KALIMANTAN. SOIL ANALYSIS WAS CARRIED OUT AT THE SOIL DEPARTMENT LABORATORY, FACULTY OF AGRICULTURE, LAMBUNG MANGKURAT UNIVERSITY, BANJARBARU. THIS RESEARCH WAS CONDUCTED FROM MAY TO JUNE 2025. THE PURPOSE OF THIS STUDY WAS TO ANALYZE THE PATTERN OF PHOSPHORUS AVAILABILITY IN RELATION TO SOIL pH AND EXCHANGEABLE ALUMINUM. THIS RESEARCH USED A SURVEY METHOD WITH A DESCRIPTIVE-EXPLORATIVE APPROACH. SAMPLING WAS CARRIED OUT USING PURPOSIVE SAMPLING AT 15 SAMPLE POINTS, WHICH WERE THEN ANALYZED FOR SOIL pH, EXCHANGEABLE ALUMINIUM, AND PHOSPHORUS AVAILABILITY. THE RESULTS OF THE STUDY SHOW THAT THERE IS NO STATISTICALLY SIGNIFICANT CORRELATION BETWEEN PHOSPHORUS AVAILABILITY, SOIL pH, AND EXCHANGEABLE ALUMINIUM. NEVERTHELESS, THE FORM OF THE RELATIONSHIP BETWEEN PHOSPHORUS AVAILABILITY AND SOIL pH INDICATES A POSITIVE LINEAR RELATIONSHIP. AS WELL AS THE RELATIONSHIP BETWEEN PHOSPHORUS AVAILABILITY AND EXCHANGEABLE HAVE A NEGATIVE LINEAR RELATIONSHIP. THE RELATIONSHIP BETWEEN SOIL pH AND EXCHANGEABLE ALUMINIUM SHOWED A NEGATIVE LINEAR RELATIONSHIP.
