A reliable, precise, proven and profit driven system, CF N-Min enables farmers to optimise Nitrogen utilisation by making the most of Additional Available Nitrogen. With the aim of balancing Nitrogen inputs to achieve the maximum economic output.
Developed over 30 years in conjunction with leading research organisations and rigorously tested on farms the length and breadth of Britain, the unique and patented CF N-Min is unlike any other soil testing and Nitrogen assessment test.
CF N-Min not only measures the amount of Nitrogen in the soil at that time but also what will become available to the crop between the spring and harvest- the Additional Available Nitrogen. Don't miss out on free Nitrogen!
With the largest soil N dataset in the UK and the our resources behind them, both N-Min and N-Calc are subject to ongoing investment, research and an exacting trials programme. This makes sure they remain as relevant and accurate as possible with rotations changing, new varieties becoming popular and farming practices developing.
FACT: only 50% of fields using RB209 to access SNS predict crop requirements within 50kg N/ha of the optimum.
CF N-Min in practice
Getting started with CF N-Min
CF N-Min and N-Calc are carried out simply and effectively in conjunction with your CF Fertilisers’ distributor.
They will supply the N-Min kit and talk you through how it is used on-farm, collecting soil samples, returning these for analysis and delivering the results.
They will also work with you on using these alongside N-Calc to ascertain the optimum Nitrogen applications for your enterprise based on your crops, varieties, yield targets and quality aspirations.
CF N-Min is an essential tool for all arable growers looking to get the highest economic efficiency from their crops, but is particularly recommended in the following situations:
Fields with unknown history
Where organic manure has been applied
High organic matter is present in the soil
Diverse soil types
Fields that have grown crops that are known to leave behind large residues of Nitrogen.
