CF Fertilisers N-Calc uses the N-Min result to arrive at the most profitable recommendation for your crops.
With the farmer's yield & quality expectations it will calculate the optimum Nitrogen fertiliser rate for cereals and OSR.
Soil Nitrogen Supply (SNS) = Crop Nitrogen + Soil Mineral Nitrogen (SMN) + Additionally Available Nitrogen (AAN)
N-Calc has been developed from CF Fertilisers own and independent research work. Recently ADAS was commissioned to review, update and improve N-Calc by incorporating all the latest research. It is an ongoing process.
N-Calc recommendations will:
- Ensure farmers' yield & quality aspirations are met.
- Allow changes in economic circumstances to be accounted for.
- Minimise the environmental impact of crop production.
- Ensure that every £ spent on Nitrogen is well spent.
