SOIL AND PLANT ANALYSIS (1+1)

Collection of soil samples from a profile

• After the profile has been exposed, clean one face of the pit carefully with a spade and note the succession and depth of each horizon.


• Prick the surface with a knife or edge of the spade to show up structure, colour and compactness.


• Describe the profile as per the standard terminologies.


• Use the Munsell colour chart for noting the colour and find out the texture by feel method.


• Collect samples from each horizon by holding a large basin at the bottom limit of the horizon while the soil above is loosened by a khurpi. Mix sample and transfer to a bag after labelling.
