What this dot point is asking
CCEA wants you to describe the production of one common farm crop (choose a cereal, potato, fruit or vegetable) from choosing the site through to distribution, identify the main costs at each phase, name the main types of farm machinery, and explain how organic methods would change the way that crop is grown.
Producing one farm crop (worked example: potatoes)
You only need to know one crop in detail. Potatoes are a clear example; the same structure works for a cereal, fruit or vegetable.
For potatoes specifically: a well-drained fertile soil is chosen, the field is ploughed to a fine seed bed, seed potatoes are planted in spring, the crop is fed and protected against blight and eelworm, lifted with a harvester, then stored cool, dark and frost-free before grading, packing and transport.
Costs at each phase
Each phase costs money, and a farmer must identify these to work out whether the crop is profitable:
- Land (rent or its value) and seed.
- Fertiliser and manure.
- Sprays (weedkillers, pesticides, fungicides).
- Machinery and fuel (ploughing, planting, spraying, harvesting).
- Labour.
- Storage and transport/distribution.
Farm machinery
Each machine is adapted to its job, and machinery saves labour and time but adds cost.
Organic methods
Producing the same crop organically would differ by:
- Using farmyard manure and compost instead of artificial fertiliser.
- Building fertility with crop rotation and legumes.
- Controlling pests, diseases and weeds by rotation, mechanical weeding and natural predators rather than spraying.
The result is usually lower yields and more labour, but a product that can be sold as organic at a premium price.
Examples in context
Example 1. A maincrop potato grower. A grower selects a well-drained field, ploughs and cultivates it, plants certified seed potatoes in spring, feeds and sprays the crop against blight, lifts it with a harvester in autumn, and stores it cool and dark before supplying a supermarket. Each stage adds cost, so the grower tracks these against the price received to stay profitable.
Example 2. Switching a vegetable field to organic. A vegetable grower converts a field to organic production. They stop using chemical sprays and fertilisers, introduce a rotation with a clover ley to fix nitrogen, and weed mechanically. Yields drop and labour rises, but the vegetables earn an organic premium and the grower gains access to the organic market.

Q1. List, in order, four stages in producing a farm crop. [4 marks]
- Cue. For example: prepare the seed bed, plant the seed, control pests and weeds, harvest, then store and distribute (any four in a sensible order).
Q2. State one way organic crop production differs from conventional production. [1 mark]
- Cue. It avoids artificial fertilisers and pesticides, using natural methods such as manure and rotation instead.

CCEA Unit 1 style6 marksDescribe the main stages in producing a chosen crop (for example potatoes) from preparing the field to getting the crop to the supermarket.Show worked answer →
Six marks for an ordered account of the main stages of one named crop.
Using potatoes as the example:
Site and soil: choose a suitable site with a well-drained, fertile soil of the right pH. Seed bed preparation: plough and cultivate the field to make a fine, firm seed bed, adding fertiliser or manure for nutrients.
Planting: plant seed potatoes at the correct spacing and depth, usually in spring. Crop nutrition and care: feed the crop, and control weeds, pests (such as eelworm) and diseases (such as blight) through the season.
Harvesting: lift the potatoes when mature using a harvester. Storage, processing and distribution: store the potatoes in cool, dark, frost-free conditions, then grade, pack and transport them from the farm store to the supermarket.
Markers reward a logical sequence covering site/soil, seed bed, planting, nutrition, pest/disease/weed control, harvesting, storage and distribution.
CCEA Unit 1 style4 marksExplain how producing a crop using organic methods would differ from conventional production, and name two types of machinery used in crop production.Show worked answer →
Two marks for the organic differences and two for the machinery.
Organic methods differ because they avoid artificial (chemical) fertilisers and pesticides. Instead, the organic grower uses natural fertilisers such as farmyard manure and compost, builds soil fertility with crop rotation and legumes, and controls pests, diseases and weeds by natural means such as rotation, mechanical weeding and encouraging natural predators rather than spraying chemicals.
The result is usually lower yields and higher labour, but a product that can be sold as organic, often at a premium price.
Machinery used in crop production includes the tractor, the plough, cultivators or harrows, the seed drill or planter, the sprayer, and the harvester (any two). Markers reward the no-chemicals point with natural alternatives, plus two correctly named machines.
