## What is OpenSoil?

OpenSoil is a powerful tool for farmers and agronomists that helps accurately calculate fertilizer requirements, optimize costs, and increase yields with the support of artificial intelligence.

Main features
Soil analysis
– Enter sensor or laboratory data on N, P, K content (kg/ha).
– Forecast natural yield without fertilizer application.

Fertilizer rate calculation
– Planned yield (t/ha) for a given area (ha, ares, m²).
– Fertilizer dosage per hectare and for the entire field, taking into account conversion factors.
– Automatic selection of a sequence of complex and single-component fertilizers to fully cover NPK deficiencies.

AI recommendations
– OpenAI integration: step-by-step agronomic advice tailored to Ukrainian climate and specific crops.
– Consideration of application timing, dosage, and best agronomic practices.

Professional PDF report
– Automatic export of fertilizer rate tables and textual recommendations.
– Easy sharing of reports via email or messengers.

How it works:

Select a crop from the database.

Enter soil data (N, P, K), planned yield, and area.

Tap “Calculate fertilizers” to get:
• Natural yield from the soil
• Percentage yield increase
• Fertilizer application rates (N, P, K) per hectare and for the entire field

Then move on to fertilizer selection – the system automatically filters out unnecessary options and builds the optimal application sequence.
Get an intelligent AI-powered recommendation and save it as a PDF.

Why choose OpenSoil
– Save time and resources: forget manual calculations, just a few taps
– Accuracy and reliability: algorithms consider actual soil properties and crop requirements
– Innovation: AI suggests the best agronomic practices
– Mobility: work directly in the field, data stored locally
