The Z955 Nitrogen Pen is a light-weight, battery-powered instrument that can be favorably used for effective nitrogen management in plants throughout their growing season. Essentially, the Nitrogen Pen characterizes nitrogen amount by means of reflectance and by the concept of a close link between chlorophyll content and nitrogen content in plants. Rugged and compact Nitrogen Pen can be favorably used in the field, in the plant biology lab or for education. The use of the Nitrogen Pen is non-destructive and permits quick, repeated measurements throughout the growing season.

Features:

Lightweight, hand-held design

Non-invasive measurement method

Easy two-button operation

Quick and easily repeatable measurements

Battery-operated

Applications:

Significant yield increase

Quick tuning of nitrogen management in crops

Increasing nitrogen use efficiency

Reducing the risk of yield-limiting N deficiencies

Saving labor and/or application costs

Reducing the risk of excessive fertilizer applications and subsequent environmental contamination

Agronomy research

Reading:

Displayed is the actual nitrogen reading

Nitrogen reading is calibrated for particular plant (here wheat and barley)

Calibrations for other plants may be provided

Variety or hybrid differences can greatly affect readings

Plant diseases, nutrient deficiencies and other kinds of plant stress can also affect readings

Sampling:

Simply insert the leaf between the leaf clip and the optical tip

Collects and stores individual readings and calculates the average automatically

Readings should be taken on different plants of the same species

Readings should be taken on the 2nd (maximum 3rd) youngest leaf on each plant

Readings should be taken on about the same location on each leaf (close to the mid part)
