<![CDATA[Soil acidity is the dominant factor in the phosphate amount, distribution of nutrients in the aggregate is important to supporting nutrient requirement and cycling. Furthermore, Al-P and Fe-P or Ca-P bonds trapped in soil minerals, also physically protected from loss due to associate with aggregates. Thus, the factual limitation of phosphorus becomes a topic, including various aggregate fractions changes and their effect on the slope. Soil samples were taken from 36 years old plantations consisting of 45 points with two depths (0 - 20 cm and 20 - 40 cm) on a various slope, soil samples fractionated into several aggregate fractions, namely micro (<250 µm), meso (250-2000 µm) and macro-aggregates (2,000-5,000 µm). For chemical analysis, soil pH was measured by pH meter, aluminium with the volumetric method, and P-available with Bray method. Based on the analysis, it is known that the P content in the meso aggregate is higher than P content in the macro aggregate ± 0.055 g m-2 for 0 - 20 cm ± 2.136 g m-2 for 20-40 cm depth, and ± 1.058 g m-2 for slope of 0-8% at 0-20 cm depth. In total, phosphate in the tea plantation area is very low.]]>
