INTRODUCTION• The most dominant soils are Ultisols and Oxisols• The soils are acidic, deficient in nutrients, particularly
phosphous• Indonesia have about 16.2 million ha upland soils,
located in Sumatra, Kalimantan, Sulawesi and Irian Jaya• High cost of P and K fertilizer – imbalance nutrient • Farmer prefer to applied Nitrogen fertilizer rather than
P and K fertilizer----compound fertilizer

Introduction……
Characteristic of study location• Sukamanah, Pleihari, South Kalimantan
(3°56'44.66" S 114°50'38.03" E) • 6 cropping seasons (2001-2004).• The soil used was Ultisols, derived from
claystone and/or sandstone of Dahor formation (sedimentary rocks, mainly consists of claystone and few sandstone)
• The soil is moderately deep, slightly coarse textured (loamy), exhibiting yellowish colour, and often has layers of gravel at different depth

Purpose of study
to demonstrate and evaluate the agronomically most effective ways of applying reactive phosphate rock on acid upland soils to increase and sustain agricultural production.

Methodology• The on farm trial conducted at famer fields in 2001-2004 (6 cropping seasons)
Experiment 2• A split-plot design with three replications.• Main plots: manure and non manure• Sub plots are
1. Without P fertilizer2. SP-36 300 kg ha-1
3. Jordan PR 1 ton ha-1
4. Morocco PR 1 ton ha-1
5. Senegal PR 1 ton ha-1
6. Tunisia PR 1 ton ha-1.
Experiment 1• Treatment
A. Farmer practiceB. PR 1 t ha-1 + Manure 1 t ha-1
C. PR 1 t ha-1 + Manure 2 t ha-1
• One ton of PR (containing about 300 kg P2O5 per hectare) was used to overcome soil P “fixation”

Summary• Under P-deficient acid soil conditions in South Kalimantan,
direct application of reactive PR showed significant positive responses on Maize yield
• The highest Maize yield was found under combination of PR and manure for 2 ton ha-1.
• This study suggests that phosphate rock could be an effective and efficient P source of fertilizer especially its residual effects.
• Morocco phosphate rock appears to be an effective source of P in this trial
