Calculating Required
Quantity of Solution
Determining surface area (m
In the case of ground crops, simply
multiply the length of the field by its
width.
The surface area of high-growing plants
is calculated approximately by
measuring the length of the rows and the
average height of the foliage. The result
is multiplied by the number of rows and
then by two if both sides have to be
treated.
The surface area in hectares is obtained
by dividing the number of square meters
by 10,000.
Example:
A field 120 meters long and 30 meters
wide has to be treated with a pesticide.
Area:
2
120 m x 30 m = 3,600 m
3,600 / 10,000 = 0.36 ha
