Phosphorus is an essential element in plants. Plants absorb phosphorus from the soil through root. Soil
phosphorus includes organic and inorganic phosphorus. Soil organic phosphorus can be further absorbed
and utilized by plants only if it is mineralized and decomposed into inorganic phosphorus.
In acid environment the content of inorganic phosphorus was calculated by molybdenum blue method.
