How to make better informed nutrient decisions

Information and knowledge is fundamental to making better informed nutrient decisions. Our collection of tools help you to make better nutrient decisions in making the right fertiliser choice and applying the right amount of nutrients at the right time and in the right place so that the crop yield and quality can be maximised whilst still keeping costs in check, avoiding over-fertilisation and protecting the environment.

Atfarm | Variable rate nitrogen | Photo analysis | Precision nitrogen management | Remote crop monitoring
Atfarm - precision nitrogen management made simple
Atfarm is a free online service to help farmers manage crop nitrogen by combining state of the art technology with Yara expertise
Yara N-Tester - to measure leaf nitrogen
N-Tester - to measure leaf nitrogen
The N-Tester is a hand held leaf nitrogen measurement tool which enables quick and easy readings to be taken in a growing crop to establish its exact nitrogen status.
Yara N-Sensor ALS 2 - variable rate nitrogen
N-Sensor - to variably apply nitrogen
The Yara N-Sensor is a variable rate sensor that measures crop nitrogen requirement at the time of application and variably adjusts the fertiliser rate accordingly.
Recommended analyses for arable crops
Soil testing and analysis - to identify limiting factors
Soil testing and analysis gives the background knowledge on the chemical, physical and biological status of a soil that we need in order to properly manage our soils and crops.
Leaf analysis - to identify nutrient deficiencies
Leaf analysis - to identify nutrient deficiencies
Leaf analysis is the only sure way to determine the nutritional requirements of a plant and to identify if it is suffering from a nutrient deficiency.
Grain analysis - to benchmark nutrient levels
Grain analysis - to benchmark nutrient levels
Grain analysis is an increasingly useful analytical tool, testing the nutrient content of harvested as a basis for future nutrient management decisions.

Grass growth map
Grass growth map - to benchmark production
Grass growth map shows actual regional growth rates recorded on farms throughout the country in the past seven days.
Conversion calculator
Conversion calculator
A useful tool to convert between various different units, particularly relevant for fertiliser and crop nutrition such as converting concentrations from oxide to elemental.
Fertiliser calculators
Fertiliser calculators - to compare costs
A useful collection of calculators to compare the return on investment and margin over fertiliser when using different fertilisers
CheckIT - to identify nutrient deficiencies
CheckIT - to identify nutrient deficiencies
Yara CheckIT is an agricultural mobile device app that gives farmers a photographic library of crops to allow a simple and fast identification of possible nutrient deficiencies.

What do other farmers say about Yara precision farming tools?

Dr Alastair Leake - Director of Policy at the Game & Wildlife Conservation Trust, England

"Nitrogen Use Efficiency is one of the most significant challenges mankind faces if we are to reduce carbon and nutrient emissions, yet feed a growing global population. The Yara N-Tester is a valuable and practical tool for farmers to use, backed by decades of research results, to improve efficiency.”

Graham Porter, Naveby, Lincolnshire

"The Yara N-Sensor transformed our business - It would be very difficult to farm this variable land without an N-Sensor, it is a marvellous tool for us." Read more

James O'Reilly Ballyragget Fm, Kilkenny, Ireland

"A fantastic first year with the Yara N-Sensor - we got on well with the N-Sensor last year, it is fantastic, the system worked well in daylight and darkness"  Read more

Jorin Grimsdale - Mountfair Farming, Duns, Berwickshire

“Atfarm is very simple to use, taking just 10 mins to load all my field boundaries over the 2200 hectares of farming. I like to use satellite imagery to scout for any management issues. The maps are a very visual way of picking out differences in growth and development to help prioritise decisions. There are plenty of products being developed for farmers, but some do not deliver and I wouldn’t recommend, however I would recommend farmers to try Atfarm.”
