DIY Calibration Method
Every farm is different in terms of Soil type, pasture type and climate. Pasture
measuring devices are calibrated on a regional basis and may not always be
representative of your particular farming operation.
This
DIY Calibration Method will allow you to self calibrate your Pastu
so you can make decisions with confidence on your collected data.
1. Find a range of paddocks to calibrate against
– Pre Grazing, post grazing,
and in between (approximately 5 paddocks).
2. Turn your Pastu on and set the units to mm.
3. Sit the Pastu over each of your pastures of differing growth
stages.
1600KgDM/ha 2100KgDM/ha
4. Read the height off the console and record in Column A in the table
provided.
5. Visually estimate (using consultant or experienced visual pasture
estimator) the pasture cover (kgDM/ha) underneath the pasture sensor
and record in the table provided.
6. Use the calculation steps and table to calculate your personal calibration
equation for your farm.
