N-tester Agronomist

 

 

Can measure the Chlorophyll content of plants immediately . LCD show the results.

Chlorophyll content and leaf nitrogen content has a very close realationship .The meter is conductive to impose reasonable nitrogen and improve the utilization of nitrogen. So this purpose can be to protect the environment ,espacially water resources, rather than using too much nitrogen fertilizers.
