- Soil acidification due to use of phosphorus fertilizers is small compared to that attributed to nitrogen, due to the lower amounts of this nutrient used and the lower acidification per kg phosphorus. Phosphoric acid is the most acidifying phosphorus fertilizer. - Potassium fertilizers have little or no effect on soil pH.
The factors that change the reaction rates of chemical reactions are: 1)temperature 2)concentration 3)pressure 4)physical state 5)a catalyst.
In the example above, notice that new compounds are formed from the breakdown of other molecules or atoms. Chemical reaction causes that. A chemical reaction is involved in this breakdown. The energy produced keeps us warm, maintain and repair bodies, and makes us able to move about.
