Di Ammonium Phosphate

It temporarily increases the soil pH, but over a long term the treated ground becomes moreacidic than before upon nitrification of the ammonium.

Calcium Ammonium Nitrate

Can be considered as near-neutral in its effect on soil pH and therefore can be used on soils that have a low pH without lowering further.

Single Super Phosphate

(SSP) was the first commercial mineral fertilizer, and it led to the development of the modern plant nutrient industry.
