Agricultural Economics, Farm Management and Marketing
This domain tests whether you can cost an enterprise, keep and interpret records, and explain how produce moves from farm to consumer at a price.
Costs and margins
Variable costs change with the size of the enterprise (seed, fertilizer, chemicals, casual labour, transport). Fixed costs do not (rent, insurance, depreciation of buildings and machinery). Gross margin = gross revenue − variable costs, and it compares enterprises. Profit = total revenue − all costs, fixed and variable. Partial budgets test a single change; cash flow shows timing of money in and out.
Records and marketing
Records include cash book, labour book, inventory, livestock register and production records. Marketing functions are buying, selling, transport, storage, grading, processing and financing. Channels run from farm gate to wholesaler, retailer or cooperative. Price depends on supply and demand, quality, season and perishability; value addition (grading, packaging, processing) raises the share of final price kept by the farmer.
Worked example
Two hectares of tomatoes yield 15 t/ha at 200 units per tonne. Revenue = 2 × 15 × 200 = 6,000 units. Variable costs: seed 400, fertilizer 900, chemicals 500, labour 1,200, transport 600 = 3,600. Gross margin = 6,000 − 3,600 = 2,400 units. Fixed costs are 1,500, so profit = 2,400 − 1,500 = 900 units. The gross margin describes the enterprise; profit describes the whole farm.
Traps that cost marks
Gross margin is not profit. Classifying a cost as fixed or variable depends on the time frame and the decision being made. Convert units carefully (price per kg versus per tonne). Sunk costs should not influence a forward decision. High yield does not guarantee high profit if costs or prices are poor.
