產(chǎn)品描述：
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)
