Hanna Instruments HI38050 Nitrate test kit soil / water

$214.50

Hanna Instruments test kit for nitrate in water and soil. This kit tests for NO3-N. The kit can be used for testing nitrate in irrigation water in the range 0-50 mg/L in steps of 1 mg/L or in soil in the range 0-60 mg/L in steps of 2 mg/L. A calcium sulphate extraction is used to extract the nitrate from a soil sample. Nitrate is determined in a sub sample of filtrate. Two times the observed result in mg/l is equivalent to mg/kg or ppm in the soil. The instructions give typical nitrate values and relate these to growth needs and fertilizer applications. To get the best results from this kit, results taken over the growth cycle should be compared to observed growth and production for a particular crop.

All equipment to perform the water and soil tests is supplied. There are 100 tests for water and 100 tests for soil.
