Soil fertility has direct implications on the agricultural
production scenarios of a region. Surface soil
samples at 1 km grid were collected to assess the fertility
status of Lakhimpur district (Assam) in North
East India. Fertility parameters like soil organic carbon,
available nitrogen, phosphorus, potassium, iron,
manganese, zinc and copper were determined using
standard analytical procedure. Spatial distribution
maps of the soil parameters were generated using
regularized spline method in ArcGIS 10.0. The average
soil organic carbon content was 1.05% and the
maximum area was under high availability status
(78%). In the case of nitrogen, 57% of the area was
under low availability status. In the case of available
potassium and phosphorus, the areas under low availability
status were 48% and 49% respectively. But for
micronutrients, in general, the availability status was
high except for zinc, which indicated that 40% of the
area was under low availability. A methodology was
developed to integrate the individual nutrient layers
using a set of decision rules to identify the multinutrient
deficient zones. The integrated map showed that
24% of the area had multiple nutrient deficiencies and
fell under high priority zone that warrant immediate
nutrient management interventions to mitigate the
situation.
