Rule Descriptions for Soil Quality and Soil Fertility Assessment using Fuzzy Control System

The three major elements or fertilizers of the soil are Nitrogen (N), Phosphorus (P) and Potassium (K). These three elements are necessary for the plants development and increase the productiveness of the soil. The trend for categorizing soil quality for the diversity of usages is by calculating the Soil Fertility Indexes (SFI). In this paper, we have created a fuzzy control system using scikit-learn-fuzzy or skfuzzy (Fuzzy Logic Toolbox for Python) for Soil quality and fertility assessment, based on fuzzy rules to suggest suitable nutrients for the crops and relate to linguistic classification of soil excellence with degree of confidence in Nainital district of Uttarakhand, India.
