5.6 Soil NPK:
In the soil suitability analysis for grape growing, NPK is an important
input component. Using soil analysis data, maps of nitrogen, phosphorus,
and potassium are created.
Nitrogen (N) is a chemical element that occurs naturally in the
environment. Nitrogen is one of the most significant chemical features
of soil for suitability classification because it ensures that energy is
accessible when and where the plant needs it for optimal output. Soil
data were used to create a map depicting the nitrogen variance in the
research area. Nitrogen levels range from 73 to 594 kg/ha in the studied
area. As a result, the research area’s nitrogen spatial distribution map
reveals that the soil is ideal for grape growing.
Phosphate (P) :-Phosphate is another chemical feature of soil
that is used to classify its suitability. Using soil data, a map of the
research area’s Phosphate variance was created. Phosphate levels vary
from 17 to 139 kg/ha in the studied area. The majority of the soil in
Rahud village is extremely favorable for grape growth, according to the
geographical distribution map of phosphorus.
Potassium (K):- Another essential chemical property for the
Grapes crop site suitability assessment is potassium. Using soil data, a
potassium map for the village of Rahud was created. Potassium
levels in the study area range from 227-860 kg/ha. Potassium levels are
rising in the research area’s centre and northern regions.
