Abstract
Air dry soil should be ground to pass through a 0.5 mm sieve. A 2.5 g soil sample is suspended in 50 ml of NaHCO3 solution of pH 8.5 along with 1 teaspoon of carbon black. Fine suspension is shaken for a period of 30 minutes. The solution is filtered through a Whatman No.40 or other suitable filter paper. A 5 ml aliquot of clear filtrate is pipetted in to 25 ml vol. flask. A volume of 5ml acid molybdate is added and the flask is allowed to stand for the generation of CO2. After that add 10 ml distilled water, then 1 ml stannous chloride (working solution), by immediate shaking and make up the volume to 25 ml and mix thoroughly. Prepare a blank as above and read the intensity of colour developed, at 660 nm, after 10 minutes and within 20 minutes.
