YielixCrop Rotation Planning: Building a Healthier Rotation
Plan sequences before choosing a crop year by year
A rotation changes the crop sequence across a field so disease hosts, nitrogen contribution, and weed-management options are considered together. The Crop Rotation Planner scores a five-crop sequence using its defined disease-family, legume, and diversity rules.

Score your 5-crop rotation for disease break, nitrogen fixation benefit, and weed diversity using family-based analysis.
Use crop families and sequence as planning signals
A useful rotation separates consecutive crops from the same disease family, includes legumes where they fit the farm system, and varies crop families. Those choices can also change planting dates, canopy structure, and herbicide options.
The planner classifies crops into its listed families. It is a transparent planning aid, not a diagnosis: field history, known pathogens, markets, equipment, soil tests, and local restrictions still determine whether a sequence is suitable.
Formula and units
rotation score = disease-break points [0–40] + N-fixation points [0–30] + weed-diversity points [0–30]
different consecutive families = 10 disease-break points per transition
The score is unitless. In the live tool, up to two legumes earn presence points and a legume directly before a high-nitrogen-demand crop can earn a placement bonus.
Worked example: retained five-crop rotation fixture
Enter the live calculator's verified sequence: soybean → corn → canola → potato → onion.
- Each of the four transitions changes disease family, so disease break = 4 × 10 = 40/40.
- Soybean is one legume (10) and directly precedes corn, a high-nitrogen-demand crop (+10), so N fixation = 20/30.
- The sequence has five represented families, so weed diversity = 30/30.
The calculator returns 90/100 with the interpretation good. That interpretation describes this tool's scoring rules, not a guarantee of yield, disease control, or nutrient supply.

Treat the score as a conversation starter
A low factor identifies the next question to investigate: repeated families, no legume contribution, or limited diversity. Compare potential sequences before committing acres, then pair the plan with local disease information, re-cropping intervals, and expected crop heat requirements in the Growing Degree Days Calculator.
Assumptions and limitations
- The tool accepts exactly five crops and applies fixed family and point mappings.
- Its nitrogen points indicate sequence placement; they do not calculate a fertilizer credit or replace a soil-test recommendation.
- It does not model local pathogen species, herbicide carryover, weather, economics, residue management, or field-specific agronomic constraints.
Common mistakes
- Equating a high score with a field recommendation: check the actual disease and pest history for each field.
- Counting a legume as a measured nitrogen credit: use local guidance and soil-test information for nutrient decisions.
- Ignoring the order of crops: the tool rewards a legume immediately before a high-nitrogen-demand crop.
- Forgetting herbicide labels and re-cropping intervals: verify them before finalizing the sequence.
