Checking the number of plants per hectare
2 methods are possible:
- Checking by counting over a set distance.
- Checking the spacing between seeds.
Checking by counting over a set distance
Example:
Seed row spacing: 75 cm (2’5’’).
The seed count must be made over a length of
13.30 m
(43’8’’)
.
The count gives 83 seeds over a length of
13.30 m (43’8’’).
Multiply the number of seeds per 1000:
83 x 1000 = 83000 seeds/ha.
Seed row spacing Counting length
30 cm (1.18’’) 33.33 m (109’4’’)
35 cm (1.38’’) 28.57 m (93’9’’)
40 cm (1.57’’) 25.00 m (82’)
45 cm (1.77’’) 22.22 m (72’11’’)
50 cm (1.97’’) 20.00 m (65’7’’)
55 cm (2.16’’) 18.18 m (59’8’’)
60 cm (2.36’’) 16.66 m (54’8’’)
65 cm (2.56’’) 15.38 m (50’5’’)
70 cm (2.75’’) 14.28 m (46’10’’)
75 cm (2.95’’) 13.30 m (43’8’’)
80 cm (3.15’’) 12.50 m (41’)
The KMS412 control box enables knowing
instantaneously the average number of plants
sown per hectare.
If the distance between the real population and
the population target exceeds 4 %, the
difference can be reduced by modifying the
gearbox ratio.
