iv. Water logged land
v. Cattle shed
vi. Residential area

iii. Large: 10-20 samples
iv. Small area: 5-10 samples
e) Sample size 250-500 gm
f) Shade drying
h) Sieving and storage
i) Make final samples for each category, then analyze and recommend for each category of land separately.
j) Depth of samples
k) Agronomical crops : 0-6 inch
l) Horticultural (tree) crops: 1m
m) Different layers of soil depth can also be taken but tedious expensive.
n) Sampling purpose: It may be for farmer recommendation, research purpose, to study nutrient forms and
