Indonesian Rock-phosphate Effectivity for Maize Crop on Ultisols Soils [PDF]

, 2012
Rock phosphate is a slow release phosphate source which can be directly used on acid soils. There are some rock phospahate deposits in Indonesia. Total phosphate and calcium content in rock phosphate vary between 8.79 – 31.88% P2O5, and 0.60 – 57.50% Ca.
