GCE A/L Agricultural Science study plan

Map the full Domain 1 syllabus into a one-page concept tree covering photosynthesis, transpiration, mineral nutrition, and crop growth stages

Explain in writing how light, CO2 concentration, and stomatal behaviour interact to set net assimilation rate in a C3 crop

Draw and label the internal anatomy of a monocot and a dicot stem and root, then state two functional consequences of each difference

Classify ten named field crops by life cycle, photosynthetic pathway, and photoperiodic response

Compute crop water requirement for a named crop using reference evapotranspiration and a published crop coefficient

Sequence the operations for land preparation, sowing, and transplanting of one named crop and justify each timing decision

Describe the formation of the three soil texture classes and predict drainage and water-holding behaviour for each

Interpret a soil pH value and select an appropriate liming or acidifying amendment with a reasoned rate

Compare cation exchange capacity of sandy, loamy, and clay soils and explain the practical consequence for fertilizer timing

Distinguish the roles of the three primary macronutrients and diagnose three named deficiency symptoms from written descriptions

Solve monohybrid and dihybrid crosses including test crosses, and state the expected phenotypic ratios

Explain how soil organic matter and microbial activity influence nutrient availability and soil structure

Label the ruminant digestive tract and explain the fate of dietary carbohydrate, protein, and fibre at each compartment

Calculate a simple ration to meet the crude protein and energy requirement of one named class of livestock

Compare rumen fermentation with monogastric digestion and list three feeding implications of the difference

Outline the reproductive cycle of one named species and identify the timing of service or insemination

Describe the causes and control of three named livestock diseases, distinguishing infectious from nutritional causes

Explain the principles of silage and hay making and identify the moisture and fermentation conditions that determine quality

List the main causes of post-harvest loss in a named perishable crop and match each to a control measure

Compare storage methods for a named grain crop in terms of moisture content, temperature, and expected storage life

Calculate gross margin for a named enterprise from given yields, prices, and variable costs

Distinguish fixed from variable costs and explain how the distinction changes a short-run production decision

Compute the cost of operation of a tractor or a pump set, including depreciation, fuel, and maintenance

Describe the working principle and field adjustment of one tillage implement and one harvesting implement

Explain the principles of conservation agriculture and evaluate one trade-off against conventional tillage for a named soil type

Describe three practices that reduce soil erosion and quantify the mechanism by which each reduces loss

Outline the components of a farm record-keeping system and state how each record supports a management decision

Identify the main environmental risks of fertilizer and pesticide use and name a mitigation for each

Re-derive the five weakest concepts identified across weeks 1 to 7 and explain each aloud without notes

Complete two full-length timed practice papers under exam conditions and record the score by domain

Analyse every incorrect practice answer and assign it to a domain and a cause of error

Build a one-page revision sheet of formulas for water requirement, ration, gross margin, and machinery cost
