Weeds have purpose. Amount of stress corn (or any crop for that matter) feels due to lack of supporting weeds is often transformed into viral and bacterial sickness.
“Weeds are weeds! No good! Pusley is weed and no good for crop! My textbook says so!”
“That’s what people think. Look at this. Look at this broken corn roots scattered among Pusley roots. You know what does that mean? Pusley roots are helping corn roots by breaking the dirt/soil so that corn roots can go deeper. Got it? Pusley is helping corn to better manage its nutrition and so good healthy crop.”
Weeds are good.
Based on my reading of book :”Weeds, guardians of the soil”.
