Proba.By (Проба Бел)

Proba.by (ООО «Проба Бел») is a precision agriculture service provider focused on soil agrochemical analysis and nutrient management planning to improve crop yields and optimize fertilizer use. In practice, they offer a technology-enabled soil diagnostics service that includes: 1) Automated soil sampling using specialized equipment with GPS-referenced sampling points and consistent sampling depth. 2) Laboratory analysis of soil samples covering 130+ agrochemical parameters, including pH, macro- and micronutrients, humus content, electrical conductivity, soil type, and base saturation. 3) Digital mapping of fields, including variable-rate fertilizer application maps based on sampling grids of about 1–3 hectares. 4) Agronomic recommendations and nutrient management plans developed by experts based on the analysis results. 5) Agronomic support for implementing the recommended fertilization system.

The service references variable-rate fertilizer maps from a 1–3 ha sampling grid, sampling capacity of ~1000–1500 ha/day, and report delivery in 10–20 working days after sampling completion.

• Large size farms
• Medium size farms

The service is provided for crop farms and agronomy teams that want to stop applying fertilizers “by eye” and move to field-by-field nutrient management. It can also be useful to farm advisors supporting fertility restoration, cost optimization, and preparation of variable-rate application tasks.

• Fee for service

Claimed outcomes include profitability uplift (15–30%), fertilizer cost reduction (up to 30%), and “profitability yield increase” of 10–40%. Operational metrics listed on the site include sampling throughput (~1000–1500 ha/day) and report turnaround (10–20 working days).
