STELZNER® agricultural measurement systems

N-min nitrogen quick test

Colorimetric determination of the concentration of nitrogen (and optionally pH value) in soils and plant samples.
 
Depending on the crop, samples should be taken of the soil up to a depth of 100 cm in order to determine plant-available nitrogen. The nitrogen quick test is a proven tool for monitoring and creating the N balance. This can be used to determine the amount of nitrogen required on agricultural and horticultural land.
Depending on the version, the test kit also includes pH strips to determine the soil pH value. The latter is a proven indicator of the availability of nutrients, soil structure and soil activity.
The Nmin test consisting of filter beakers, 50 circular filters, 100 x nitrate test strips, (optional 100 pH test strips 0-14), volume beaker (100 ml) and funnel. Tables and worksheets for N-outdoors, N-substrata and N-sap are also included in the test kit.
