Krashak

Krashak is an offline mobile app that helps farmers calculate precise fertilizer dosages for crops by comparing Recommended Nutrient Value (RNV) with local soil test reports (STR), so users can make better nutrient-management decisions without needing constant internet access. The app bundles a comprehensive, inbuilt database of soil test reports covering every block in every district of every state in the country while also allowing manual entry of soil-test values for nitrogen, phosphorus and potassium. Krashak streamlines dose calculation, reduces over-fertilization risk and supports sustainable, yield-oriented fertilizer planning for both smallholders and larger farms.

Key Features

⭐ Krashak calculates fertilizer doses offline by matching crop RNV with local STR data for reliable recommendations.

⭐ Inbuilt soil test database covering every block, district and state across the country removes the need to search for external reports.

⭐ Manual entry for soil test values (N, P, K) lets you override database figures or use your own lab results.

⭐ Simple, intuitive interface designed for users with limited digital experience.

⭐ Dose suggestions aimed at optimizing yield while minimizing waste and environmental impact.

Advantages

✅ Accurate, science-aligned recommendations based on RNV and STR comparisons.

✅ Krashak works offline, reducing dependence on lab access and internet connectivity in remote areas.

✅ Helps lower the risk of over-fertilization and associated environmental harm.

✅ Accessible workflows suit both small-scale farmers and larger agricultural operations.

Disadvantages

❎ Focuses on macronutrients (N, P, K) and does not provide guidance for micronutrients or other soil health indicators.

❎ Database coverage applies to the country included in the app; users outside that area may need local data.

❎ Accuracy depends on correct soil test values, so users should enter verified STR data when local conditions differ from database entries.
