- 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 The clues of a chemical reaction are production of a gas, change in temperature, color change, production of a precipitate. 2  In a chemical reaction, it takes energy to break the bonds in the reactants and energy is released when bonds are formed in the products.
