WACE ATAR Agricultural Science and Technology study guide
WACE ATAR Agricultural Science and Technology · Work through your exam, one topic at a time.
The WACE ATAR Agricultural Science and Technology course is a Western Australian senior secondary subject examined externally for ATAR ranking. It suits students interested in how food and fibre are produced, from soil and pasture through plant and animal management to the technology, economics and sustainability decisions that shape real farm businesses. The WACE ATAR Agricultural Science and Technology study guide has 6 sections and about 1,731 words.
01Agricultural Systems and the Environment
An agricultural system is a managed ecosystem: energy and nutrients enter, are transformed by plants, animals and soil organisms, and leave as product, runoff, gas or waste. Candidates must distinguish inputs, processes, outputs and feedbacks , and compare systems on productivity, stability, resilience and sustainability .
299 words, about 1 min02Plant Production and Management
Plant production is driven by genotype × environment × management . Understand photosynthesis and respiration , the growth stages of a crop (establishment, vegetative, reproductive, grain fill, maturity), and how temperature, water, light and nutrients limit yield.
313 words, about 2 min03Animal Production and Management
Animal production depends on genetics, nutrition, health, welfare and environment , and the producer's job is to convert feed into product efficiently. Understand feed intake and digestibility , metabolisable energy and protein , the difference between maintenance and production requirements, and how feed conversion ratio and average daily gain measure performance.
260 words, about 1 min04Agricultural Technology and Innovation
Technology in agriculture is adopted when it solves a real constraint profitably. Candidates should understand precision agriculture (yield mapping, variable-rate fertiliser and seed, soil and EM surveys, GPS guidance and autosteer, section control), remote sensing (satellite NDVI, drones, thermal imagery), sensors and the internet of things (soil moisture probes, water meters, animal collars and virtual fencing), automation and robotics , data analytics and decision support , and biotechnology (marker-assisted selection, genetic modification, gene editing) within regulatory frameworks.
292 words, about 1 min05Sustainable Resource Management
Sustainable resource management means maintaining or improving the resource base while producing profitably. Understand soil as a resource: texture and structure, soil organic carbon , cation exchange capacity, pH, biology and the role of ground cover in erosion control.
276 words, about 1 min06Enterprise Planning, Economics and Marketing
Farm decisions are economic decisions. Understand fixed versus variable costs , gross margin (enterprise income minus variable costs), gross margin per hectare , overhead costs , whole-farm profit , cash flow versus profit , and return on assets .
