Fertiliser plans and nitrogen planning
A fertiliser plan from soil tests, not habit
Nirby prepares fertiliser recommendations for each zone of the field. It takes into account soil nutrient levels, crop needs, Nitrates Directive requirements and eco-schemes, and you turn the plan into a variable-rate map.
- 01
Zone recommendations
Different rates for different parts of the field, based on soil nutrient levels.
- 02
Nitrates Directive and eco-schemes
The plan accounts for the requirements the farm must meet.
- 03
Straight to a VRA map
Turn the fertiliser plan into an application map for the machine.
How a fertiliser plan is made
Soil results turned into a specific rate.
Soil results go straight into the plan: instead of one rate for the whole field you vary it by zone, and Nirby turns the plan into an application map.
Fertiliser plan features
Fertiliser plans in one system with fields and soil.
The fertiliser plan uses the field, crop, previous crop and soil results already in Nirby.
Recommendations from soil results
Phosphorus, potassium and magnesium rates follow the nutrient level in each zone.
Nitrogen planning
Nitrogen rates matched to the crop and Nitrates Directive requirements.
Eco-schemes
The plan accounts for the eco-schemes the farm takes part in.
Nutrient balance
See the nutrient balance for fields and the whole farm.
Field history and previous crop
The plan uses the rotation and treatment history recorded in Nirby.
Export to a VRA map
Turn the plan into a variable-rate map and load it onto the machine.

FAQ: fertiliser plans
Frequently asked questions about fertiliser plans
Does Nirby create fertiliser plans?
Yes. Nirby creates fertiliser plans from the crop, soil nutrient levels and lab results, with recommendations for each zone that account for crop needs, Nitrates Directive requirements and eco-schemes.
Does the fertiliser plan account for the Nitrates Directive?
Yes. Fertiliser plans in Nirby account for Nitrates Directive requirements, so nitrogen rates are planned with the rules the farm must follow in mind.
Does the fertiliser plan account for eco-schemes?
Yes. Fertiliser plans in Nirby account for eco-scheme requirements, which helps plan fertilisation in line with the practices the farm is paid for.
Where does Nirby get the data for the plan?
From the fields, crops and rotation recorded in the system and from soil results assigned to zones. You enter data once and use it in later seasons.
What is a zone fertiliser plan?
A plan in which the rate differs between parts of the field according to soil nutrient levels and crop needs. It can be turned into a variable-rate (VRA) map.
Can the plan be loaded onto a spreader?
Yes. Turn the zone plan into a VRA application map, export it as ISOXML or Shapefile and load it onto a compatible ISOBUS terminal.
How much does fertiliser planning cost?
Fertiliser plans are in the management module and zone plans in the precision agriculture module, billed per hectare per year. Your first year worth up to PLN 240 is free.
For advisers, laboratories and distributors
Do you work with farmers? Let’s build something together.
Nirby can connect farmers, advisers, laboratories, distributors and crop buyers around the same data. Tell us how you work and we’ll suggest a practical partnership model.
- 01
Distributors & advisers
Fertilisers, crop protection, seed and machineryAdd fertiliser plans, application maps and crop monitoring to your offer. Advisers can work from the same field data as the farmer and discuss specific management zones instead of relying on whole-field averages.
- 02
Soil sampling companies
Laboratories and field crewsWe define sampling zones from satellite imagery and turn lab results into nutrient maps and precision fertiliser plans. You collect the samples; the farmer receives clear recommendations and machine-ready files.
- 03
Agri-food supply chain
Processors, crop buyers and producer groupsBring supplier field-operation and crop-protection records into one digital standard. That makes crop traceability, reporting and contract-growing programmes easier to manage.
