- 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.
1 Factors that affect reaction rates: 2  concentration of reactants. 3  Increasing the concentration of reactants in solution increases the number of reactant particles which increases the number of collisions so the reaction rate increases.
