Phosphorus availability and exchangeable aluminum response to phosphate rock and organic inputs in the Central Highlands of Kenya [PDF]
Soil acidity and phosphorus deficiency are some of the constraints hampering agricultural production in tropical regions. The prevalence of soil acidity is associated with phosphorus (P) insufficiency and aluminum saturation.

Agronomic and financial benefits of direct Minjingu phosphate rock use in acidic humic nitisols of Upper Eastern Kenya [PDF]
A major constraint to crop production in Sub-Saharan Africa is nutrient deficiency, especially phosphorus (P) deficiency. Phosphorus plays a crucial role in photosynthesis but is usually deficient in acidic soils since it is converted to less available ...

INDONESIAN ROCK-PHOSPHATE EFFECTIVITY FOR MAIZE CROP ON ULTISOLS SOILS [PDF]
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.
