Each plant and its soil life form have a particular soil pH it is used to. It is like blood pressure in our bodies, that varies many levels even within a day. Any change can lead to complications in the organism’s metabolism. Decrease in pH modifies top soils, a major source of crop nutrients.
Soil pH declined significantly from the 1980s to 2000s in nearly all crop production areas in India and China. Average decline was between 0.13 and 0.8. Typically pH value hovers at an average of eight across most lands of the world. Continue reading
