Krashak

Krashak is an offline mobile assistant that calculates fertilizer dosages using crop Recommended Nutrient Value (RNV) and local soil test reports (STR), helping farmers apply appropriate amounts of nitrogen, phosphorus and potassium to improve yield and reduce waste. The app includes an extensive built-in database of soil test reports covering every block in each district and state and also accepts manual soil data input when local test results differ, allowing planning without internet or a nearby laboratory.

Key Features

Key features include an offline fertilizer dosage calculator based on crop RNV and local STR, an extensive database of soil test reports for every administrative block, and manual entry for macronutrients so Krashak adapts to actual soil values. The interface is designed for users with limited technical experience and recommendations are presented clearly to help avoid over-application and reduce input waste.

Advantages

Krashak works without internet, making it useful for farmers in remote areas or those without lab access. The app helps reduce the risk of over-fertilization and supports more sustainable nutrient management by combining local soil data with crop nutrient needs to produce practical, field-ready recommendations suitable for smallholders and larger operations.

Limitations

The app focuses on macronutrients (N, P, K) and does not provide detailed micronutrient analysis or specific micronutrient recommendations. Results depend on the quality and timeliness of soil test data, and complex soil problems may still require laboratory diagnostics.
