  • Page 50 7. Adjustments and operations IMPORTANT - Data in the previous tables (seed and fertilizer) may vary due to many factors. Therefore, we request that you carefully pay attention to the following topic: Practical test for seeds and fertilizer distribution The most appropriate way to assess the amount of seed and fertilizer to be distributed is on the same field where sowing will be carried out, as follows: - Whenever it is possible, use the same tractor and operator for sowing.
  • Page 51 7. Adjustments and operations Auxiliary calculation for seeds and fertilizer distribution In order to distribute other amounts of seed and fertilizer using spacing and areas which are different from those depicted in the tables, we suggest a quick calculation, where all used data can be replaced by data of your own interest using the formula below, which contains the following elements: A = area to be seeded or fertilized (m²).
