Compare export-crop revenue and variable costs for the stated enterprises.
Verified published formula · Enterprise gross margin
Fictional default example · 2025.
What the selected record shows. The supplied 600 kg at 2,000 LKR/kg gives 1,200,000 LKR revenue. After 650,000 LKR variable costs, gross margin is 550,000 LKR.
Next step. Review the prices, quantities and costs behind the margin. Prepare margin comparison in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
Gross margin excludes fixed costs and does not establish net profit.
Gross margin = saleable output × realized price − variable costs. Divide by matching hectares for margin/ha; variable-cost break-even price = variable costs / output.
Keep fixed costs, family-labour opportunity cost, taxes and financing identifiable. Gross margin is not net profit. Crop, prices and costs are fictional coherent enterprise assumptions. Gross margin excludes fixed and financing costs; it is not household income or net profit.
Other required records: Crop; harvested output; realized prices; variable costs; cultivated hectares.
Food and Agriculture Organization of the United Nations · Farm Management for Asia A Systems ApproachInstitution publication · Chapter 4, Gross margin and section 4.7.1
Per-hectare and variable-cost break-even outputs are algebraic rearrangements. Local costs, prices and interpretation still need confirmation.
Calculation appendix
Compare market-development options using quality, buyer, capacity and resource evidence.
Validation required
What the selected record shows. There is not enough information to choose this option. Obtain the records and evidence about conditions listed below. The supplied budget less cost is 300,000 LKR.
Next step. Obtain the missing records before choosing. Prepare evidence request in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
Budget headroom does not establish market demand or export eligibility.
Compare each alternative's stated benefit, adverse effects, domain evidence and mandatory constraints. Where cost and budget are supplied, budget balance = budget − option cost. A budget balance alone does not determine domain feasibility or select an option.
Other required records: Crop-market options; demand evidence; quality requirements; access costs; risks.
Reconcile spice-processing input, output, by-products and stock.
What the selected record shows. Unaccounted physical share: 6.667 %.
Next step. Reconcile the input, output, stock and transfer records. Prepare loss-balance review in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
An unexplained mass balance is not automatically a measured processing loss.
Unaccounted = input − saleable output − usable by-products − closing stock − transfers out. Share =100 × unaccounted / input.
Use a consistent moisture basis and process boundary. Unaccounted mass is not automatically avoidable food loss or spoilage.
Other required records: Crop batch; input weight; output weight; moisture; rejection cause; stage.
Compare matching harvested output and harvested area for export crops.
What the selected record shows. Harvested crop output: 2,800 kg; Matching harvested crop area: 2 ha. This gives 1,400 kg/ha.
Next step. Check matching outputs, denominators and operating conditions. Prepare performance comparison in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
Yield differences do not identify their agronomic causes.
Harvested crop output / Matching harvested crop area, for the same product, process and period.
The fictional example uses saleable dry pepper from matching harvested area; green and dry output are not combined.
Other required records: Crop; harvested kilograms; mature hectares; age; season; production system.
Check soil, climate and crop-requirement evidence for proposed export crops.
What the selected record shows. The required evidence is incomplete for this crop suitability case. The items below identify what must be obtained or reconciled.
Next step. Obtain the missing evidence listed below. Prepare evidence request in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
A complete evidence record does not establish crop suitability.
Check each required item and retain its reference. A documented item is not a scientific, legal or institutional approval.
Evidence completeness alone cannot establish suitability, eligibility, safety, permission or method validity.
Other required records: Crop requirements; soil; rainfall; temperature; slope; shade; water access.
Compare valid planting-material stock with matching demand and delivery windows.
What the selected record shows. Uncommitted usable stock: 310 plants. Review replenishment gap.
Next step. Review replenishment gap. Prepare stock review in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
Availability alone does not establish certification or provenance.
Usable = physical−quarantined−expired (non-overlapping groups). Available = usable−commitments. Additional gap = max(0, new demand−available).
Stock must be compatible by item, lot, condition, expiry and delivery window. Do not allocate quarantined/expired stock or silently erase overcommitment.
Other required records: Crop variety; usable nursery stock; approved demand; lead time; health status.
Identify unusual crop-health observations for a field or diagnostic review.
What the selected record shows. Difference: 6 affected plants per 100 inspected.
Next step. Check the unusual observation and its comparison basis. Prepare investigation brief in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
Observed changes do not establish a disease diagnosis or control treatment.
Later/comparison value minus Comparable reference value. Relative change = 100 × difference / Comparable reference value when the earlier value is positive.
Other required records: Crop; symptoms; diagnostic result; affected hectares; survey effort; baseline.
Compare the spice test result with the stated method, specification and sample details.
What the selected record shows. The supplied Fictional spice-lot moisture, wet-basis mass percent result is 13.5 %. Its stated comparison range is 0 to 12 %. Outside example comparison bounds.
An illustrative moisture bound is not an adopted export specification.
Compare the measured value only with matching parameter, unit, use and averaging period. Retain limit source/version and censored-result status.
Example bounds establish no compliance or diagnosis. Ambient, drinking-water, effluent, crop, food, air and noise standards are not interchangeable. A censored result is not an exact zero. Wet-basis mass percentages must be between 0 and 100; the buyer or laboratory specification still needs confirmation.
Other required records: Lot; moisture; contaminants; analytical method; buyer specification; unit.
Compare rehabilitation and replanting choices for an ageing stand.
Cost alone does not establish future yield or the best replacement strategy.
Other required records: Stand age; yield; disease; replant cost; income gap; options.
Identify export-crop growers without confirmed technical support.
What the selected record shows. 30 growers are known to be uncovered; 5 have unknown coverage. 65% are confirmed covered.
Next step. Check the records behind the uncovered and unknown groups. Prepare coverage follow-up in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
Coverage does not establish whether the support met the grower's need.
100 × distinct covered eligible units / eligible frame. Known uncovered = frame − covered − unknown.
Count each eligible unit once for the selected service and period. Received messages, attendance, adoption and outcomes are separate measures.
Other required records: Grower register; needs; extension visits; adoption evidence; crop area.
Check grower and production evidence for a certification request.
What the selected record shows. The required evidence is incomplete for this certification readiness case. The items below identify what must be obtained or reconciled.
The page does not certify a grower or product.
Other required records: Grower ID; scheme version; production records; inspections; traceability; nonconformities.
Compare grading, drying or processing cash-flow scenarios.
Verified published formula · Discounted cash-flow NPV
What the selected record shows. At the supplied 8% annual discount assumption, the five-year cash flows and residual value give 109,847.353 LKR net present value after the initial investment. The figure compares cash flows under these assumptions.
Next step. Review the cash flows, discount assumptions and constraints. Prepare cash-flow comparison in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
Present value depends on the supplied volumes, prices, costs and discount assumption.
NPV = −initial investment + sum of year1…5 net cash flows discounted at the stated annual rate, including residual value once in year5.
Match currency, price year, real/nominal basis and cash-flow timing. The example rate and five-year horizon are assumptions, not institutional financing terms; no credit approval follows.
Other required records: Equipment cost; throughput; operating costs; product prices; losses; discount rate.
Food and Agriculture Organization of the United Nations · Guidelines for defining financial economic environmental and social informationInstitution publication · Sections 2.2.2 and 2.2.3, discounting and Net Present Value
The five-year horizon, discount rate and cash assumptions are local settings. Verification does not approve an investment or loan.
Find lot-to-farm links whose source identity or lineage needs checking.
What the selected record shows. Broken or affected lineage: 1 items. Investigate linked downstream lot.
Next step. Investigate linked downstream lot. Prepare source comparison in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
A missing link must not be replaced with an invented farm origin.
Follow recorded upstream→downstream links within the same scope and period. Flag missing links; a confirmed defect identifies downstream linked candidates for authorized investigation.
Recorded lineage is not proof of product identity or recall authority. Preserve multi-source batches, transfers and versions; do not clear unlinked lots as safe.
Other required records: Farm ID; harvest lot; processor lot; transfer records; shipment ID.
Check harvest task windows against capacity and quality prerequisites.
What the selected record shows. Planned duration: 3 days. Resolve overlapping resource bookings.
Next step. Resolve overlapping resource bookings. Prepare schedule review in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
The schedule does not establish the best market price or authorise harvesting.
Check start/end order, operating window, effort, predecessor completion and overlapping bookings for the same resource. A conflict is flagged; no optimal schedule is invented.
Other required records: Crop maturity; weather; labour; processing capacity; buyer delivery window.
Compare shade, soil-cover and water-adaptation choices using local evidence.
Stated benefits remain assumptions until supported for the crop and site.
Other required records: Crop exposure; practice costs; water requirement; yield evidence; uncertainty.
Check original planting cohorts after crop-development assistance.
What the selected record shows. Confirmed survival lower bound: 78 %.
Next step. Check unknown follow-up separately from confirmed survival and failure. Prepare cohort follow-up in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
Replacement plants do not count as survivors of the original cohort.
Lower =100 × known survivors / original cohort. Upper =100 × (known survivors + unknown) / original cohort. Survivors + known failures + unknown = original cohort; replacements do not enter it.
These bounds account for unknown status; they are not statistical confidence intervals. Use actual follow-up dates and distinguish cohort membership from repeated visits.
Other required records: Assistance cohort; planted hectares; survival; follow-up date; inspection evidence.
Compare proposed research questions, evidence gaps, resources and expected use.
Affordability alone does not establish scientific merit or research priority.
Other required records: Crop constraints; trial evidence; grower demand; research cost; applicability.
Use supplied soil-loss factors to prepare erosion-assessment evidence.
Verified published formula · USLE factor product
What the selected record shows. Estimated annual sheet/rill loss: 15.641 t/ha/year.
Next step. Check local factor and site evidence before selecting a detailed erosion assessment. Prepare assessment brief in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
The estimate does not itself select a conservation treatment.
R × K × LS × C × P, using a mutually consistent SI factor set.
This USLE factor product is not a full RUSLE2 run, measured loss, delivered sediment, gully loss or landslide forecast. Local factors and uncertainty need review.
Other required records: Erosivity; soil erodibility; slope; cover; conservation practices; site.
United States Department of Agriculture Forest Service · A Guide for Predicting Sheet and Rill Erosion on Forest LandGovernment publication · 1980 technical publication SA-TP 11; Universal Soil Loss Equation, printed page 2; metric conversion appendix, printed page 40
The historical source verifies the factor product. Local factor choice and suitability still need confirmation; this is not a full RUSLE2 implementation.
Find inconsistent crop and variety definitions before reconciling records.
What the selected record shows. The required evidence is incomplete for this grower records case. The items below identify what must be obtained or reconciled.
Names alone do not establish varietal identity or genetic equivalence.
Other required records: Source crop label; scientific name; variety registry; definition; steward decision.
Compare enterprise outcome changes in supported and comparison observations.
Verified published formula · Difference-in-differences arithmetic
What the selected record shows. Treatment change: 170,000; comparison change: 70,000; difference in changes: 100,000 LKR/ha. This comparison alone does not establish causation or benefit.
The difference alone does not establish an effect of the support programme.
(Treatment after−before) − (comparison after−before), using the same outcome definition and periods.
The arithmetic alone does not establish causation. Design, parallel trends, confounding, attrition, uncertainty and adverse effects need appropriate evidence.
Other required records: Supported growers; baseline margin; follow-up margin; comparison group; market conditions.
World Bank · Impact Evaluation in Practice Second EditionInstitution publication · Chapter 7, table 7.2, printed page 140, PDF page 170
The formula is verified. Causal interpretation still requires a defensible study design, comparison and assumptions.
Source. International publication.
Data needed. Product form, lot ID, moisture test result, sampling method and destination specification.
Method. Compare measured moisture with the applicable limit for the stated pepper form and grade. Use a comparable test method and retain the result by lot.
Worked example. A whole black pepper lot tests at 13.5% moisture against a 13% buyer limit. Hold the lot for a quality review and check the agreed method and destination specification.
Next step. Refer a lot outside the applicable limit for drying, retest or quality review under the buyer’s terms.
