Yield losses and damaged area

When it is needed

In disagreements about the damaged area, yield shortfall and the connection between losses and a particular event.

What we examine

Damaged areas and control zones.
Yield and harvest accounting data.
Loss calculations and initial agronomic parameters.

Materials to prepare

Field map and materials about the damaged area.
Inspection, control count and sampling data.
Weighing documents and produce moisture and quality information.
Calculation method applied, fields compared and weather data.

Sample questions

What damaged area is supported by the input data?
What are the grounds for selecting the comparison yield?
Have differences in moisture, quality and cultivation conditions been considered?
Does the calculation include double counting or unjustified assumptions?
What physical extent of losses can be determined within the submitted set?

How the work is carried out

Check damage boundaries and comparability of accounting data.
Analyse the calculation model and alternative input parameters.
Present a calculation of the physical extent of losses with assumptions explained.

Result

A verifiable calculation of area and physical losses, or a list of data without which that calculation is impossible.

What affects the conclusions

A district's average yield does not replace justification of the expected outcome for a particular field. Monetary assessment of damage and lost profit is agreed as a separate brief.

Frequently asked questions

Can a neighbouring field be used for comparison?

Yes, if the crop, variety, soil, cultivation practices and seasonal conditions are comparable. Significant differences must be considered.

Will you assess the amount claimed?

The agronomic part establishes the initial quantitative parameters. Financial calculations require separate checking of prices, costs and the damage model.

How to combine yield accounting documents into a verifiable calculation

Loss calculations may simultaneously use data from harvesting, transport, acceptance, drying and subsequent sales. Before comparing them, identify which produce and stage each entry describes. Mass before conditioning and finished lot mass may differ for reasons unrelated to crop damage.

It is useful to compile a table by fields and dates: area, quantity harvested, weighing document, moisture and impurity information, transfer to storage and subsequent conditioning. If produce streams were combined with other fields or lots, record this separately. An overall farm statement does not always isolate the result for the disputed area.

Cross-checks

Whether the same lot is included in several transport and acceptance entries.

Whether the period, field and crop match in the documents and calculation model.

The mass basis used for the compared parameters and how conversion was performed.

Whether it is known which produce remained in the field, was harvested, sorted or lost later.

The next stage is to distinguish actual shortfall from assumptions about expected yield. The comparison inputs must correspond to the particular field's conditions. If several justified alternatives exist, it is useful to show their effect on the calculation. This check explains the quantitative conclusion's robustness. Monetary claims are considered after agronomic and accounting quantities are established; they cannot be replaced by a simple difference between two incomparable weighing totals.
