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.
