SR 340, SR 420 English / USA Calculating RequiredQuantity of Solution Step 1: Determine surface area (m2) In the case of ground crops, multiply the length of the field by its width. The surface area of high-growing plants is calculated approximately by multiplying the length of the rows by 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 area in hectares is obtained by dividing the number of square meters by 10,000. Example: A field 120 meters long and 20 meters wide has to be treated with a pesticide. Area: 120 m x 30 m = 3,600 m2 3,600 / 10,000 = 0.36 ha...
