Usage

Potato Analyses

A specialized suite of crop-specific analyses for potato fields, including yield prediction, starch content estimation, disease risk assessment, and leaf nitrogen mapping.

Growth Period Parameters

Potato analyses use crop-specific date parameters instead of the standard startDate/endDate:

sowingDate REQUIRED

The date potatoes were planted. Must be 2023-01-01 or later.

expectedHarvestingDate REQUIRED

The expected harvest date. Growth period must be between 3 and 9 months after sowing.

1. Potato Yield

Predict total tuber yield across the field based on canopy development patterns.

GraphQL Mutation

mutation { processPotatoAnalysis( polygonId: "abc123-def456-ghi789" sowingDate: "2025-04-15" expectedHarvestingDate: "2025-09-15" analysisType: "Yield" ) { Status Message Result { requestId } } }

2. Potato Starch

Estimate starch content in tubers, a key quality parameter for processing potatoes.

GraphQL Mutation

mutation { processPotatoAnalysis( polygonId: "abc123-def456-ghi789" sowingDate: "2025-04-15" expectedHarvestingDate: "2025-09-15" analysisType: "Starch" ) { Status Message Result { requestId } } }

3. Disease Prediction

Assess the risk of common potato diseases based on satellite-observed vegetation patterns. Uses a different mutation with a diseaseType parameter.

GraphQL Query

query { retrieveDiseasePrediction( polygonId: "abc123-def456-ghi789" sowingDate: "2025-04-15" expectedHarvestingDate: "2025-09-15" diseaseType: "LateBlight" ) { colorlegend tif png json } }

Supported Disease Types

Disease Type	Description
`Aphid`	Aphid infestation risk assessment.
`EarlyBlight`	Early blight (Alternaria solani) risk prediction.
`LateBlight`	Late blight (Phytophthora infestans) risk prediction.

4. Leaf Nitrogen

Map nitrogen content in potato leaves for targeted fertilization.

GraphQL Mutation

mutation { processLeafNitrogen( polygonId: "abc123-def456-ghi789" sowingDate: "2025-04-15" expectedHarvestingDate: "2025-09-15" ) { Status Message Result { requestId } } }

GraphQL Query

query { retrieveLeafNitrogen( polygonId: "abc123-def456-ghi789" startDate: "2025-04-15" endDate: "2025-09-15" ) { colorlegend tif png json } }
