Fertilizer Calculator is a valuable tool developed by KVK Banavasi for the farming community, as well as academicians, scientists, and students in the field of agriculture. This Android application provides complete nutrient management for major crops in agriculture, including vegetable crops like chilli and onion. With coverage for 21 different crops, the app aims to educate farmers about soil health and the importance of soil testing.

One of the main features of Fertilizer Calculator is its ability to provide recommended doses of fertilizers for Andhra Pradesh state, in cases where soil test results are not available. This ensures that farmers can still apply the correct dose of fertilizers based on crop-specific requirements. The app also offers soil test-based fertilizer application, allowing users to input their soil test values and receive recommendations for fertilizer combinations.

By promoting the use of crop-specific correct doses of fertilizers, Fertilizer Calculator helps reduce indiscriminate and excessive fertilizer use, resulting in cost savings for farmers and a reduced risk of soil pollution.
