#estimation

The #sulphur in #soil is #extracted with 0.15%Cacl2 , 2H2O solution the sulphate in soil extract is precipitated by using Bacl2 salt as BaSo4 the BaSo4 precipitated is kept under turbid condition in the presence of stabilizing agent (gum acacia) the intensity of turbidity is determined at 420 nm using a spectrophotometer
Colculation
Available Sulphur= R*25*25/5*10=R*12.5
R= ppm of S from standard curve

Sir volume karane kai bad reading kitani minute Mai Lene chahiye spectrometer pay
