What does the crop production module cover in CCEA GCSE Agriculture and Land Use?

It covers the Unit 1 crop and grass content: the common crops grown in Northern Ireland and identifying named grasses, weeds and crops, silage-making and grassland management including dry matter and grass yield, the factors affecting crop yield and the GM crops debate, and the production of one farm crop from site selection to distribution, including machinery and organic methods.

Which exam assesses this module?

These topics are part of Unit 1 Soils, Crops and Habitats, an externally assessed written examination with compulsory structured questions, including data and calculation questions and longer answers, set directly from the specification content.

What calculations come up in this module?

The main calculation is percentage dry matter, found by oven drying a weighed grass or silage sample and using (dry mass divided by fresh mass) times 100. You may also estimate grass yields from a rising plate meter or herbage samples, and identify the costs of producing a crop.

Do I need to know GM crops in detail?

You need to define genetically modified crops and discuss the advantages and disadvantages of their widespread use in a balanced way, linking it to feeding a growing population. You do not need the laboratory detail of how genes are inserted.

How should I revise this module?

Learn the named lists of crops, grasses and weeds, then the silage process and the three quality indicators, and drill the dry matter calculation. Learn the factors affecting yield and the benefits of crop rotation, prepare a balanced GM answer, and rehearse the ordered stages of producing one crop with its costs, machinery and organic alternative. Then practise CCEA past papers and finish with the module quiz.

What this module covers
How it is examined
How to study it

The crop production module of CCEA GCSE Agriculture and Land Use covers how crops and grass are grown, conserved and brought to market. It is examined on the Unit 1 Soils, Crops and Habitats written paper. This page maps the topics and links to a focused answer page for each one.

What this module covers

Crops, grasses and weeds: The common crops grown in Northern Ireland, identifying named grasses, weeds and crops, the need for continuous research, and how grass maturity affects nutritional value. Start with Crops, grasses and weeds.
Silage and grassland management: The silage-making process, judging silage quality by colour, smell and moisture, calculating percentage dry matter, and estimating grass yields. See Silage and grassland management.
Crop yield and GM crops: The factors affecting crop yield, the benefits of crop rotation, the definition and the advantages and disadvantages of GM crops, and the seasonal management plan. See Crop yield and GM crops.
Growing a farm crop: Producing one crop from site selection to distribution, the costs at each phase, the main types of farm machinery, and how organic methods differ. See Growing a farm crop.

How it is examined

These topics appear on Unit 1 Soils, Crops and Habitats. Expect structured questions on identifying crops, grasses and weeds, the silage process and quality, a dry matter calculation, the factors affecting yield and crop rotation, a balanced GM crops answer, and an ordered account of producing one crop with its machinery and costs.

How to study it

Learn the named lists of crops, grasses and weeds first, then the silage process and its three quality indicators, and drill the dry matter calculation. Learn the factors affecting yield and the benefits of rotation, prepare a balanced GM answer, and rehearse the ordered stages of growing one crop with its costs, machinery and organic alternative. Then practise CCEA past papers and finish with the module quiz.
