Dry matter measurement with the Martin Lishman dry matter field kit

Dry Matter Field Kit

Test the Dry Matter of Individual Tubers

Dry matter differs between varieties, but dry matter of the same variety may also vary between seasons in the same field. The Potato Dry Matter Field Kit demonstrates this variability in tubers from field samples. The results can be compared with the bulk sample methods by averaging multiple readings

Key Features

  • Highly portable – includes all equipment needed for field use. Does not need water to operate.
  • Measures individual tubers – to create a genuine average dry matter for the sample and identify tubers with hollow-heart
  • Low cost method – an accurate weigh scale, known-volume sample corer and careful technique ensures accurate results
  • Standard ware corer – individually calibrated for ware potatoes; optional salad variety size corer (22mm dia.)
  • Dry matter and specific gravity – both are measured from the volumetric weight of the sample using the conversion chart in the kit

2 Versions available

Standard Ware Potato

High accuracy scale, standard ware potato corer, penknife, filter papers, calibration chart, strong carry case

Salad Potato

How to use the Potato Dry Matter Kit – in 5 easy steps

A core is taken from a pre-cut tuber, weighed accurately together with the calibrated known-volume corer and the weight converted to percentage dry matter and specific gravity using a calibration chart.
