Krashak is a pocket agriculture assistant that calculates precise fertilizer dosages for crops and works offline, making it a practical tool for farmers who lack reliable internet or easy access to labs. Krashak combines the Recommended Nutrient Value (RNV) for a chosen crop with local soil test report (STR) data to turn lab figures into clear fertilizer recommendations that help optimize yields and reduce waste. The app also includes an extensive inbuilt database of soil test reports by block, district and state, and lets users enter their own N, P and K soil-test results for tailored nutrient plans.

Key Features

Offline fertilizer dosage calculator uses crop RNV and regional STR data so recommendations are available without an internet connection. The inbuilt STR database provides local context at block, district and state levels. Users can manually input soil-test values for nitrogen, phosphorus and potassium to receive tailored nutrient plans. Crop-specific nutrient recommendations are presented clearly to help minimize over-application. A simple, intuitive interface is designed for users with limited digital experience and for both small-scale and larger agricultural operations.

Advantages

Krashak enables accurate fertilizer planning without an internet connection, supporting decision-making in remote areas. The app helps reduce waste and the risk of over-fertilization by matching doses to soil and crop needs. A large built-in STR database speeds decision-making while manual entry keeps recommendations flexible. The straightforward workflow makes nutrient management accessible to a wide range of farmers.

Disadvantages

The app focuses primarily on macronutrients (N, P and K) and may not provide guidance on micronutrients. Recommendations depend on correct soil-test data or accurate manual inputs, so incorrect values will affect results. Krashak is a decision-support tool and users should consider local extension advice or laboratory guidance when necessary.
