The Yara N-Tester is a hand held tool which enables quick and easy non-destructive measurements to be taken in a growing crop to establish its nitrogen status.
What is the Yara N-Tester?
The Yara N-Tester is a hand held tool which enables quick and easy non-destructive measurements to be taken in a growing crop to establish its nitrogen status. This enables both more timely nitrogen applications as well as fast and accurate field specific nitrogen recommendations to help fine-tune final dressings towards the end of the growing season.
This can result in more accurate nitrogen management, improving profitability and nitrogen use efficiency whilst minimizing environmental impact.
Why use the Yara N-Tester?
The nitrogen fertilizer demand is never constant and can vary considerably from year to year and field to field. This has been demonstrated by recent Yara trial work showing that optimum nitrogen rates have varied from under 100kgN/ha to over 300kgN/ha.
Two of the main influencing factors of nitrogen fertilizer demand in a cereal crop are the amount of nitrogen that is supplied by the soil and the efficiency of uptake, neither of which can be accurately measured directly. With the N-Tester it is possible to identify the nitrogen status of plants directly in the field, easily, safely and quickly.
A plant analysis with the N-Tester gives valuable information about the current nutritional status of the plant, helping to identify the amount of both soil nitrogen and fertilizer nitrogen the crop has been able to pick up. The nutritional status of the plants determines both the timing and later in the season, the amount of fertilizer required.
The result? Improved gross margins and greater nitrogen efficiency
