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 ( |
