Plan optimal crop sequences to improve soil health, manage diseases, fix nitrogen, and maximise long-term profitability.
Quick answer: Include a break crop every 2-3 years. Legumes fix 50-150 kg N/ha. Good rotations increase following wheat yield by 0.5-1.5 t/ha. Example: Wheat → Canola → Wheat → Lupin → Wheat.

📐 Why Rotation Matters
Good rotations increase profit by $100-300/ha/year compared to continuous cropping. Benefits include:
Disease control — Break crop every 2-3 years reduces take-all, crown rot, sclerotinia
Weed management — Different herbicides and planting times control resistant weeds
Nitrogen fixation — Legumes add 50-150 kg N/ha for following cereals
Soil structure — Deep-rooted crops improve water infiltration
Include a legume every 3-4 years to maintain nitrogen fertility. Canola is an excellent break crop for cereal diseases. Avoid two grass crops (wheat/barley) in a row.
❓ Frequently Asked Questions
Common rotations: Wheat-canola (2 years), Wheat-barley-canola (3 years), Wheat-canola-lupin-wheat (4 years). Include break crops every 2-3 years to manage disease and weeds.
Breaks disease cycles, manages herbicide-resistant weeds, improves soil structure, fixes nitrogen. Increases yield by 10-30% compared to continuous cropping.
Lupins: 80-150 kg N/ha, Field peas: 60-120 kg N/ha, Chickpeas: 40-80 kg N/ha, Pasture legumes: 50-150 kg N/ha.
A non-cereal grown to interrupt disease cycles and weed pressure. Examples: Canola (breaks cereal diseases), Legumes (fix nitrogen, break diseases), Oats (suppress weeds).
