Document Parsing and Chunking for Crop Farming Due Diligence

What the Data for This Category Looks Like

Crop farming due diligence report data primarily comes from grower daily logs, soil test lab reports, meteorological observation records, agricultural product purchase contracts, and local agricultural department statistical reports. Data update cycles cover monthly planting logs, quarterly soil test results, and annual purchase agreements and statistical data. Document formats include plain text logs, test reports with structured tables, and PDF contracts and statistical reports. Fields include crop variety, plot number, yield per mu, pesticide usage, harvest period, and more. Units mostly follow agricultural-specific metrics such as grams per mu, milliliters per mu, and kilograms per hectare.

What Constraints Do These Characteristics Impose on Document Parsing and Chunking

The multi-type structure of crop farming due diligence documents requires the parsing process to adapt to plain text, tables, and mixed-format content without missing structured data. Specialized measurement fields require retaining the binding relationship between fields and units, to avoid splitting and losing associated information. Documents with different update cycles must be split into chunks by time node. Each chunk must cover a complete planting cycle or a single test report, to avoid mixing data across cycles. Bulk-imported logs and test reports must support automatic matching of chunking rules by document type, to improve parsing consistency.

Configuration Settings

Configuration Item	Recommended Value	Rationale
`parse_table_enable`	`true`	Crop farming due diligence documents contain a large number of soil test and planting ledger tables, requiring complete extraction of table content and format associations
`chunk_size`	`800–1200 characters`	Single chunks of crop farming documents need to cover complete planting cycle records or a single test report, avoiding splitting critical data
`chunk_overlap`	`10%–15%`	Retain overlapping content between adjacent chunks to ensure that cross-chunk planting cycle connection information is not lost
`allowed_extensions`	`["pdf", "xlsx", "csv", "docx"]`	Cover common document formats used in crop farming due diligence, including ledger tables, test report PDFs, and contract documents
`file_parse_timeout`	`600 seconds`	Adapt to parsing requirements for large-volume annual planting ledgers or bulk test reports, avoiding timeout interruptions
`table_chunk_strategy`	`row_based`	Split table content by row, retaining complete information for individual test items and avoiding cross-row data splitting

The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require targeted analysis, and it is recommended to test on your own samples before finalizing settings.

Three Common Mistakes

Phenomenon: Imported crop farming due diligence PDF files cannot be opened for preview in the knowledge base. Cause: The pdf_preview_enable configuration item is not enabled, or the system's file storage path is not configured.
Phenomenon: Imported Excel planting ledger files cannot extract table fields. Cause: The parse_excel_table parameter is not enabled, or the correct header starting row number is not specified.
Phenomenon: When calling a custom document parsing tool, parameter verification passes but parsing logic is not executed. Cause: The tool_request_timeout parameter is not configured, or the timeout setting is too short, causing the request to be interrupted early.

How to Confirm Configuration Is Correct

Upload a standard crop farming soil test PDF report, and check if the table content in the parsing result is fully retained.
Upload an Excel planting ledger, and verify that the chunking result is split by table row or date, with no splitting across critical data.
Check the system logs to confirm that the parsing task execution time does not exceed the threshold set by file_parse_timeout.
Test a call to the custom parsing tool, verify that the request body format and parameters match the configuration items, with no error returns.
