3- ESSENTIAL SOWING CONCEPTS
It should be taken into account that a seed’s germinating power is variable and dependant on multiple
factors. It can be experimentally calculated to be between 70% and 80%, which is practically equivalent
to multiplying the number of grains to be sown by 1,43 or 1,25 respectively.
Next, we describe a practical method to determine the number of kilos per hectare to be distributed
once we know how many plants per square metre we want to obtain.
1)
Place seeds on the “seed counter”
Wipe seed counter with your hand to make sure that there is only one grain per slot (100
grains in total). Do the same 10 more times to obtain 1000 grains
2)
Weigh 1000 grains with the precision scales. We call the result the OPERATIVE WEIGHT.
3)
Once we know how many seeds per square metre we are going to sow, we should adjust
the following kilograms per hectare in the dosing control:
kilograms per hectare = (grains per m2 x OPERATIVE WEIGHT) / 100
