Plantwise Factsheets for Farmers
Recognize the problem
testing is important in estimating the physical, chemical and biological
properties of soil. It will help to decide the exact nutrient requirement for
the crop. It also provides information on the existing nutrient status after
Soil testing helps
to record the available nutrients in the soil. Based on the soil testing
results, precise requirement for each crop can be calculated.
The results can also
give the farmer an idea about what crops are most suitable for the field according
to the availability of nutrients. This scientific method saves the cost of
fertilizer application as the soil will supply nutrients in an available form
during the critical stages of the crop growth. This prevents unnecessary
accumulation of unutilized fertilisers and thereby prevents harmful effects to
- Walk in a
zig-zag manner in the field. Remove the surface litter in 10 randomly selected locations.
Using an auger or spade, make a ‘V’ shaped cut to a depth of 15 cm or according
to the crop cultivation. Collect 0.5 to 1.0 kg of representative soil samples
and put them in poly bags. Label the bag giving the details of the field, crop,
farmer name survey number, sample number and date of collection.
- Do not
collect sample around fences, bunds, trees etc.
not collect sample during heavy rainfall, water stagnation or in fields where
organic manure has been applied
of bio fertilizers could supplement 25% of the total requirement of the
nutrients and also promote soil fertility in an eco-friendly manner
