For determining the nitrate content in soil

The nitrate-nitrogen advisory kit allows you to carry out quick on-site tests to determine the nitrate content in fruits and plant material. It is important to determine the proper amount of nitrogen needed at the correct time for your crops.

The instruction manual includes safety tips and practical recommendations for working with soils (Nmin) with varying depths and when working with water, vegetables, potatoes, grains, corn, sugar beets or grasses. The quantity and quality of your crop will both suffer if you use too little or too much nitrogen. With our nitrate-nitrogen advisory kit, you can accurately determine the proper fertilization schedule for your crops.

Measuring nitrates in fruits, plant materials and soil

Measuring instrument for electronically evaluating the colour scale on Merckoquant nitrate test strips. The "Nitrachek" system has established itself as an indispensable tool in many countries. New: The previous 20 measurements are saved with date and time stamps. There is a new automatic corrective-factor multiplication feature. When used properly, the Nitrachek delivers results with a statistical stray zone of about ±10 % accuracy. This is a respectable value for this application range.
