NCEA Level 2 Agricultural and Horticultural Science study plan

Map the full NCEA Level 2 Agricultural and Horticultural Science topic list into a one-page concept map linking soils, plant growth, animal production and management practices

Define in your own words the core vocabulary of soil science (texture, structure, porosity, cation exchange capacity, pH) and write a one-sentence definition for each

Explain how soil texture and structure affect water-holding capacity and drainage, using one New Zealand pastoral and one horticultural example

Practise interpreting a soil texture triangle by classifying five sample compositions you invent yourself

Describe the role of the major plant nutrients (N, P, K, S, Ca, Mg) and trace two micronutrients through a deficiency scenario

Explain how soil pH affects nutrient availability and justify a liming decision for a stated soil test result

Compare three fertiliser application methods (broadcast, banded, fertigation) and state one advantage and one limitation of each

Calculate a simple nutrient application rate from a given area and product percentage

Explain photosynthesis, respiration and transpiration and link each to a practical management decision such as irrigation timing or shade

Describe the environmental requirements (light, temperature, water, day length) for growth of two named New Zealand crops or pasture species

Outline the plant reproductive cycle from flowering to seed or fruit set and identify where pollination failure can reduce yield

Compare vegetative propagation (cuttings, grafting, division) with seed propagation for two named horticultural crops

Describe the anatomy and function of the ruminant digestive system and contrast it with monogastric digestion

Explain how feed quality and quantity influence liveweight gain and milk production, using feed conversion ideas

Identify the main animal welfare requirements under New Zealand codes of welfare for a named livestock class

Explain the purpose and timing of three routine livestock management practices (for example drenching, tailing, shearing)

Describe the components of an environmental management plan for a farm, including nutrient budgeting and effluent management

Explain how riparian planting and fencing reduce nutrient and sediment loss to waterways

Identify the main greenhouse gas sources on a New Zealand farm and describe one mitigation option for each

Summarise the purpose of key New Zealand agricultural regulations and industry assurance programmes relevant to on-farm practice

Describe the main pests and diseases of two named crops and two livestock classes and state one control method for each

Explain integrated pest management principles and apply them to a single named pest scenario

Distinguish between preventative, cultural, biological and chemical control and give an example of each

Explain how biosecurity incursions are detected and managed at the farm and national level

Interpret a set of production data (yields, liveweights, costs) and identify the most likely cause of a stated change

Explain the relationship between inputs, yield and profitability for one pastoral and one horticultural enterprise

Describe how market requirements and quality grades influence on-farm production decisions

Practise writing a structured extended answer that uses data as evidence within a time limit

Revise the whole concept map, filling any gaps identified from earlier weeks' deliverables

Complete a full practice paper under exam conditions and self-mark using the marking schedule

Correct every error from the practice paper by writing a short explanation of the correct reasoning

Condense the glossary and key diagrams into a single one-page revision sheet
