- 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.
A chemical reaction produces a chemical change as atoms are rearranged resulting in the production of one or more new substances. In all chemical reaction there is a conservation of mass. Atoms are neither created nor destroyed. Chemical reactions are generally difficult to reverse. eg.
