On this episode we discuss bulk density and fertiliser calibration to maximise your fertiliser spreading ability.
Bulk density is a major factor affecting the spreading ability of a particular fertiliser product. Bulk density is the weight of a given volume of fertiliser and measures how heavy a fertiliser is. 
For example, urea has a bulk density of 0.76 (760 g per 1 litre of volume); CAN has a bulk density of 1.0 (1000g per 1 litre volume). Higher bulk density fertilisers are easier to spread at larger working widths.

Fertiliser calibration is a very important task to be carried out going forward given the price of fertiliser and mounting environmental and water quality pressures. Fertiliser calibration will ensure fertiliser is applied evenly and correctly, therefore ensuring maximum efficiency.
When calibrating the fertiliser spreader, it is important that flow rate of fertiliser from the machine is matching the desired flow rate.
