Yield estimate

Expected: 4.2 t/ha — range 3.6–4.8

Capabilities

Four modules: from soil measurements to an NPK plan in kg/ha.

Each module can be used independently. Together they cover the full cycle: simulate yield with WOFOST 8.1, derive an NPK plan in kg/ha, run nitrogen scenario simulations, and query the recommendation reasoning.

01 · predict

Yield prediction

Estimate final grain yield for a selected crop and location using local soil, weather, and management information. The system provides an expected yield value together with an uncertainty range to support agronomic decision-making.

02 · Plan

NPK recommendation

Derives N, P₂O₅ and K₂O doses (kg/ha) from the predicted yield gap and the crop's nutrient demand curve. Each dose is cross-referenced against regional anchor observations to bound the recommendation.

Scenario simulation

Run WOFOST 8.1 with EnKF across multiple N doses (kg/ha) and read the resulting TWSO curves and LAI trajectories side by side. Identify the dose where yield gain no longer justifies the input cost.

Agronomic agent

Ask questions about a recommendation in plain language. The agent returns the underlying indicators, the comparable reference points, and the prediction interval. No opaque outputs, full traceability.

What NPK doses for my maize field - soil pH 6.4, V6 stage?
Recommendation for maize V6, semi-arid zone: N 96 kg/ha, P₂O₅ 48 kg/ha, K₂O 32 kg/ha. Calibrated to WAF-04 anchor region - confidence 0.91.

The interface, as it runs in the field.

Select a coordinate on the map, configure the crop and N management parameters, then run the WOFOST 8.1 simulation. Results appear below the map: a scenario comparison table with yield bars and a TWSO accumulation curve tracking growth day by day through the season.
