why do farmers need to know the ph level of their soil
Soil pH Soil pH is considered a master variable in soils as it affects many chemical processes. It specifically affects plant nutrient availability by controlling the chemical forms of the different nutrients and influencing the chemical reactions they undergo. The optimum pH range for most plants is between 5.5 and 7.5;[2] however, many plants have adapted to thrive at pHÂ values outside this range.
Leaching (pedology) Laterite soil, which develops in regions with high temperature and heavy rainfall, is an example of this process in action.
