Agricultural Economics and Farm Management
What you must understand
Farm management applies business thinking to the farm. Know the factors of production (land, labour, capital, management) and the difference between fixed and variable costs. Understand gross margin (gross output minus variable costs), gross and net profit, break-even point, and the meaning of cash flow versus profit. Learn record types - physical, financial, labour - and why records support decisions, credit and planning. Understand marketing: supply and demand, price, market channels, grading and packaging, value addition, and the role of cooperatives. Know the meaning of depreciation, working capital, credit and interest, and simple budgeting. Farm planning includes choice of enterprise, rotation, labour scheduling and risk management.
Traps in questions
- Confusing gross margin with profit; gross margin ignores fixed costs.
- Treating depreciation as a cash payment; it is a non-cash charge.
- Mixing up fixed costs (rent, insurance) with variable costs (seed, fertiliser, casual labour).
- Assuming high yield always means high profit; price and cost matter.
- Forgetting that records are needed for credit applications.
Worked example
A hectare of maize yields 4 000 kg sold at 5 units/kg = 20 000 units gross output. Variable costs are seed 1 000, fertiliser 3 000 and casual labour 2 000 = 6 000. Gross margin = 20 000 − 6 000 = 14 000 units. If fixed costs are 9 000, net profit = 14 000 − 9 000 = 5 000 units. Rule of thumb: compare enterprises by gross margin per hectare, not by yield alone.
