Growing the sun flower

[S1lver]

Hi! I want to plant 40 hectares of sunflower. I heard from someone that you cannot grow sunflower a few years in a row and you have to switch to another plant for the land where you planted the sunflower. Is that true? If yes, why?

Can be boggers for sclerotinia never seen any other serious problem that might persist.

They say that the soil is no longer as fertile after several consecutive years of growing sunflower (and I'm not sure if it's only about sunflower or all the agricultural plants ), so I'm asking you, is that true? Do I need to plant something else after 2-3 years of sunflower?

not a good idea to be growing any mono culture crop continuously, a rotation of plant types is always best
Having said that, sunflowers are no harder or easier in the soil than any other crop
They do have a strong aggressive tap root ( like a thistle ) which makes them a good scavenger / recycler of deeper nutrients & moisture
The biggest issue of growing them continually is sclerotinia, as mentioned.
Sunflowers used to be a big commercial crop here in the past, but always in a 3 or 4 year rotation - & we are a much drier environment im assuming
