Which of the following is not a method of placing fertilizer in the soil before and after sowing?

  • A.Deep placement
  • B.Contact placement
  • C.Subsoil placement
  • D.Aquatic placement

Answer: D

The method that does not exist is Aquatic placement.

Fertilizer placement methods put the fertilizer where roots can use it. Deep placement puts it in the reduced zone of flooded rice soils, contact placement puts it close to the seed, and subsoil placement puts it in the subsoil of strongly acidic or deep-rooted situations. Others include band, plough-sole and pellet placement.

There is no fertilizer method called aquatic placement; the word refers to water, not to a position in the soil, and is the distractor.
